Last years in the market of stores appreciable growth of popularity of external devices is observed. The reasons of it are clear — rarely tops can, and bottoms want. Could not Earlier, even because of a sluggishness of standard mass external interfaces. However, at some users of a choice special was not, so stores (as optical, and NJMD) with LPT-interfeysom were on sale in the certain quantities. Only it was possible to use them only owing to a hopelessness — very much slowly. Even for then rather slow drives CD-ROM slowly — as soon as the quantity «iksov» became more than scientific notebook software two, external LPT-CDD have ceased to like buyers :) Introduction USB has helped a little, but it is only a little — the best, on what the given trunk, it approximately 6h CD-ROM while internal devices by then were already close to tops of technology, vigorously having passed for 36h is capable. Winchesters on USB worked too is rather sad, especially in view of that their volume already then was estimated in gigabaytah. To let out external DVD-ROM with USB-interfeysom in such conditions to anybody and in a head could not come — even 1h in case of these stores it already more mbyte to a second, that is it is more, than the trunk allowed. Certainly, in some cases scientific notebook software it was possible to take advantage SCSI-ustroystvami, the blessing in their case external stores is worse than nothing internal, however it demanded purchase of the controller, and external execution to and without that not to the low price of the store added on the average dollars 80. Position has significally changed after the beginning of use of trunk FireWire, to which and till now (let alone events of almost ten years' prescription) has enough even for many winchesters. No, certainly, modern model on plates on 3.5” inches "classical" FireWire 4 will limit, however not any user will notice it, not using special test programs. :) Then winchesters were scientific notebook software more slowly, and the opportunity of increase in throughput in the trunk has been incorporated initially. Not without reason specifications RS offered such variant, as Device Bay — leaving from "cleanly internal" and "cleanly external" stores aside universal models with FireWire-interfeysom. Later, the truth, Intel has grown cold to FireWire, having preferred to let out on the market the accelerated updating USB and the new high-speed consecutive trunk specially for stores (SATA). But every cloud has a silver lining — controller USB 2. quickly became a standard accessory of any computer (and, is free-of-charge" for the user), and speed of work of this trunk, let and was below, than in case scientific notebook software of FireWire, but all the same approached for the majority of applications. Supporters FireWire, first, having let out on the market updating IEEE1394b with throughput up to 8 Mbit/s (basically, it even in practice is hardly better, than not so long ago popular ATA66), and secondly did not surrender also, having brought down the prices for simple controllers of " the old sample » approximately up to dollars for a payment (while they began with 100). Plus popularity of digital chambers that has affected and popularity of controllers. As a result we today can use easily and cheaply for work with external stores USB 2. or FireWire 400, and those to whom speed is important without compromises (and is on it of money) gradually start development FireWire 8 and modern eSATA. But all this would be not so scientific notebook software interestingly, if not new needs of users. Usual bulky desktop computers gradually lose the increasing and the most part of the market. And that remains, often fill noutbuki which users not always wish to carry with themselves that is quite capable to not be useful on business trip. The optical store, for example. But it would be desirable to connect houses and it, and the winchester on 3.5” plates (last if necessary in storage of great volumes of the information where is more favourable for buying, than built in in noutbuk apgreydit'). Besides — in rather for a long time bought (but till now quite arranging) noutbuke there can be an idle time kombo-drayv, and scientific notebook software presently already and to write on DVD-diski it is time. To change noutbuchny'y a drive dorogovato, and external it will be possible and after replacement noutbuka to use. Or to use not only with noutbukom. And many users who till now have not passed to mobile computers, instead of desktops buy SFF PC. There opportunities of expansion not such and bad, however, all the same can appear insufficient. Besides — idea to hide in a case the writing drive can appear very seductive. And at the some people at home more than one computer (that is frequent, again taki, it is connected with distribution noutbukov) so stores were to be got nevertheless in a singular and to share with all them. Means, scientific notebook software the external store which it is necessary either to collect independently is required, or to buy ready. The second quite often is more compact also a guarantee on the complete set give, but at independent assembly it is possible to save often appreciable enough sum, and flexibility of such approach is a lot of above. Therefore the idea of purchase of the corresponding container and independent manufacturing of the external store from usual internal always was rather attractive. Even more attractive it became recently when transition with PATA on SATA has begun. Company Intel, for example, already has cut by half number supported by the chipsets RATA-ustroystv, and in the near future the part of chipsets will refuse any compatibility with them. And all anything, but at many users devices scientific notebook software which would be desirable to continue for using were kept. Position is even more aggravated with that till now with SATA-interfeysom is not enough optical stores. What to do after a upgrade? The conclusion is obvious — to not start better a situation, and at once "to hang up" pisalku on one of external interfaces. About such variant we today also shall talk — on an example of the container for five-inch stores from ViPowER. Basically, it can be used and for work with hard disks by means of the special adapter for installation of the last, but it, more likely, collateral functionality. We shall consider it in one of following clauses for now some words about the family of containers Smart Family, its concrete representative and experience of use of the last for creation of external drive DVD-RW. Smart scientific notebook software Family conceptually this ruler exists already more than two years, and is extremely interesting from the technical party. However, apparently, at its creation the manufacturer has overestimated it interesnost' for buyers why instead of a victory over "classical" containers we see, more likely, a return situation. Other manufacturers have not picked up undertaking ViPowER, and the firm from it, similar, refuses. Actually for everyone actual Smart-varianta already there is a "classical" replacement So in what idea Smart Family consists? In this family designers have decided to go on division actually boxes and the converter of interfaces. The idea had pluss, the main thing from which was that the user could receive easily that variant which approached it in the best degree. For example, there was no problem in buying the device in a variant for work with USB 1.1, scientific notebook software later to pass on USB 2.0, and now to get over on eSATA for house use, having kept the previous variant for « exit work ». Charm that anything to change it was not necessary — to get simply cables novee. An interesting variant also could be and economy on converters — for example if to buy two boxes (5.25” for optics and 2.5” for carry of data, for example), but one cable and to use it with that device which is necessary at present. Each box costs cheaply, the blessing of complex electronics in it is not present. At the moment of start of a series during a life scientific notebook software the main interface was PATA — ego-to updating and have accepted as standard. More precisely, inside of the container no updatings existing, and outside all devices Smart Family are supplied by identical contact sockets Mini-Centronics. Everyone « the clever cable » on the one hand is supplied by a socket of that interface which it supports, and with another a uniform socket in the increased case in which all electronics disappears also. On the market send six various Smart-ustroystv (including a box studied by us today under five-inch stores VP-6024V), and the number possible Smart-kabeley has in total made eight pieces (from ancient LPT up to modern eSATA—, at least, theoretically, it it is possible to use all this with any container). Model VP-6029V which we today consider, turns out very simply is an scientific notebook software association in one packing container VP-6024V and cable VP-9009, being converter FireWire-IDE. Why such beautiful decision has not got accustomed? First, such flexibility and scalability was required not all. The only thing, that users, probably, also would wish proapgreydit' — variants with LPT and USB 1.1. But that such was much, the device should to start be let out years pyat'-shest' back. Besides the company itself has spoiled to itself I shall impoverish, reluctantly putting on sale "naked" containers therefore with an opportunity to save, using pair boxes with one cable, it was necessary to say goodbye. And if to work with scientific notebook software the device the same as and with the usual external container advantages at it already any, but lacks remain on a place. First, it is more dear, as it is more complex. Even the in itself socket is already more complex, so and on it already any cents leave. Secondly, problems with a cable are possible. Sama-to electronics is covered seldom enough, and casually to break a cable (or still something bad with it to make) much it is possible. The owner of the usual container will go to shop and will buy to itself new USB or FireWire a cable scientific notebook software for ridiculous money, and chosen Smart it is necessary to fork up. The concept has not justified itself why in due course becomes only a part of history. So, for example, tested today VP-6029V already has disappeared from a site of the manufacturer — there were only variants with USB 2. in the complete set, and users FireWire, apparently, should look narrowly to VP-60 « without bukovok ». The box has remained same — have changed only iron back wall on which now usual FireWire-raz`em, instead of Smart, but and on the internal party it is not simple conductors, but also bridge FireWire-IDE. However VP-60 while up to our edges has not reached, but VP-6029V to buy it is possible. Besides — if someone wishes to take advantage of universality Smart Family it has all chances of scientific notebook software it. While. From the point of view of the usual user, the difference between these two variants is insignificant (except for an opportunity of failure of a cable) so to all of us it is equal what to consider. :) Very much much in their case equally. Box VP-6024V we Shall look more closely at the container, as as I have already told, in ne-Smart-modelyah it same. As it is a question of use of five-inch devices, it is obvious, that the box small cannot be: its sizes make 2 h 1 h mm. Not and it is a lot of — attempt reduce sizes could scientific notebook software to cause problems of compatibility with some devices. Structurally consists of the top and bottom half connected by metal fixture (to which the drive is fastened also) and not only. Still there are four plastic ledges and, accordingly, dredging (just the last initially were required — that assembly apertures to reach), with assistance of which and without a twisting vintikov the design appears rather strong. The matter is that for disassembly of a cover it is necessary to pull in the parties very accurately, keeping between them parallelism. The slightest skew, and all is fixed. However, for the constant use, naturally, it is scientific notebook software better vintika to twirl four, and the store to fasten, on an accessories the manufacturer did not save the blessing :) That vintiki in did not draw attention, grooves with them are closed by four elastic bands which are carrying out also functions of legs. I shall notice, that on that part which is turned upwards, left vpadinki that hints at convenience stekirovaniya several stores in such cases. « Muzzles » at the container are not present, that, probably, will upset those who plans to use it and as the chassis for the winchester. On the other hand, at assortment of the company there are many cases calculated on 3.5” devices so it is necessary to make simply correctly a choice :) Besides — if so will strongly secure, it is possible to buy at ViPowER any of Mobile Rack (which too weight) and scientific notebook software to solve a problem thus. And the back end face is closed with a metal plate to which basic elements of a design are concentrated. First, it is the switch of a feed and a socket for connection BP which continuation inside is typical konnektor type Molex. There's nothing to be done — « treshki "and" the five » to feed from the trunk, as a rule, does not leave. Unless in case of FireWire 8 it can turn out, but there and then before us a universal box. Some manufacturers build in a power unit directly the container, ViPowER prefers the separate approach. Each variant has pluss and minuses, but I scientific notebook software shall not direct to them attention now. And about parameters BP I shall tell — it provides a current 3. And on a line In and And for Century Basically, it should suffice quite to any device which you decide to establish in the container. Secondly, the interface socket. For Smart Family as I already spoke, it is contact Centronics, directly connected with internal IDE-shleyfom. In case of "usual" models the typical socket for the chosen interface is used, and on the internal printed-circuit-board is unsoldered also the bridge from it on IDE. Thirdly, is present linear audivy'hod, and inside — a four-contact comb for connection with a corresponding socket scientific notebook software of a drive (the cable in the complete set is not present). However, this way of connection has already ceased to be actual — for a long time already the majority of players "swings" data directly on the trunk, and transformation CD-ROM in CD-pleer has lost a urgency together with disappearance of button Play. And last element — the fan. It is necessary or not, solve. Basically, at me it all time drove cold air, but it together with one of last optical stores, and in case of older models all can be. To disconnect it it is simple — a feed through a standard two-contact socket. What for it can be necessary? All the same the fans of such size rotating on 60 rev/min, seldom happen silent. In this case it is impossible to scientific notebook software tell, that it very loud, but the rustle of air is audible very well. On the other hand, if to include the device only when it it is required, noise from the fan will not have time to bother:) The container can be put simply on a table or to put, using a special support (therefore it was found out, that bokoviny' not smooth not only from aesthetic reasons). However, for the given model the vertical order is should all optical drives love such orientation in space. Smart-kabel' VP-90 At first sight, it can be confused with a usual nonintellectual cable — whether a little, that one socket is a little hypertrophied :) On other end at the given model absolutely standard six-contact socket FireWire is located. For connection to mini-sockets scientific notebook software the complete set includes an adapter (of a feed in this case to care it is not necessary, the blessing it always external). Almost usual cable. The only thing that — absolutely "usual" also would be more convenient, the blessing is initially calculated on hot-plug, and Centronics not absolutely. Practice of use is the most interesting, certainly, not how it looks and as works. For practical check VP-6029V I have taken one of the newest optical drives NEC. Installation has not borrowed a lot of time, then the received assembly has been connected to integrated on parent payment FireWire-kontrolleru on the basis of chip VIA VT63 (I have taken advantage of it, instead of one of two other controllers available in a computer owing to which will be explained below).
The drive at once has been found scientific notebook software out Windows. That is pleasant, under the list of devices in case of FireWire-periferii it is possible to define the manufacturer of the concrete bridge more often. In this case it is Initio Company which makes a suitable series of bridges IEEE1394a-IDE. However, concrete products in it the whole four. The basic differences of first of them are supported ATA-protokoly': INIC-14 it is calculated only on ATA33, INIC-14 already supports ATA66, and INIC-14 — ATA100. Last chip with an index 14 it, like as, 14 in the form of one microcircuit. And what of variants is applied in VP-9009, I do not know. Basically, scientific notebook software it is very probable, that it is compact 1440. If is not present, the main question — 14 it or any of remained? The matter is that FireWire as a whole has higher throughput, than ATA so last trunk can become a bottleneck. However, happen such can only at work with the winchester — optical stores in itself slower so we shall postpone finding-out of this interesting question up to the second part of tests. Nero InfoTool has correctly defined a drive, the basic vkladke at all not paid attention to the interface of its connection :) In case of a configuration of devices it is precisely specified, what store is connected to what controller. Pay attention, that on controller VIA hangs also external hard disk ZIV Pro. The matter is that in due time to us scientific notebook software to force to work two FireWire-ustroystva simultaneously.
More precisely it was possible, but with clauses: files could be copied from CD on the winchester, but it was impossible to write on CD from the winchester. Whether there was it a problem of concrete bridges, operational system, drivers or programs of record of disks - behind prescription of years to recollect any more it is not possible. However it would be desirable to check up — whether the problem now has disappeared. Therefore one of tests was record DVD+RW by the files laying on ZIV. As the store old enough, too greater speeds to it to provide tyajelovato, but for 4h more than it is enough its scientific notebook software opportunities. For record it was used Ahead Nero versions 6.3.1. which has informed, that record will be made for minutes of seconds, all process (with creation of borders, etc.) Has borrowed minutes of seconds. Practically all time the buffer of a drive has been filled on %, with rare falling up to %. As a result it was found out, that with simultaneous work of two FireWire-ustroystv already problems any does not remain. And with data recording, at least, for the speed 4h, that gives not such small final speed in 5. Mb per second, too. But it, certainly, slowly. Earlier somehow and on 2.4h disks wrote, and especially did scientific notebook software not suffer from it, and now — alas: 4h seem to something too melancholy. We shall struggle with melancholy. Was overlooked at me three bolvanochki about which InfoTool has told shown above. Jacobs Verbatim, however what actually to meet under this trade mark in case of purchase of disks by banks on pieces in «Ashane» it can is not known (Verbatim so much disks does not let out, how many they in one Russia are on sale :)). But problems with them was not earlier, speed 16h support — ih-to and it has been decided to use. The drive was going to work on the maximal speed three and a half of a scientific notebook software minute, was in practice taken twice longer, and the indicator zapolnennosti buffers behaved, as the madman — to be devastated to it not distances, but already on first half of disk it managed to fly few times up to %, and on the second almost constantly chaotically stirred between and %. Then I have decided to write down too most on the same disk for the speed 8h. Time of record has grown time in an one and a half (but not in two), and the behaviour of the buffer almost has not changed in any way, so it not deficiency of throughput of the trunk, and something another. But what exactly and why at speed of record 4h all as a hand removes — while to tell I do not undertake. Certainly, I scientific notebook software did not try to provide to a computer hothouse conditions, but this winchester during record "touched" nobody. Having thought, I have decided to write down third bolvanku on checked up by time Plextor PX-708A. In due time it was the most high-speed drive. Now its abilities can cause only affection, but on 8h it is capable. Record has borrowed noticeably less time, than at NEC on 8h and all for a minute (!) It is more, than the last could burn down" a disk for the speed 16h, the buffer both has shown right at the beginning of %, and did not move up to the end. And exact figures scientific notebook software of time of record are resulted in the table: NEC 16x NEC 8x Plextor 8x Prospective time of record 3: 6: 6: Actual full time of record 6: 9: 7: the conclusion in due time made in Plextor Has proved to be true, in the chapter of a corner at creation of a drive speed, speed and once again speed have been put. It allows a drive later two a year after release to compete with the newest models (and, and with let out by company Plextor, and not just competitors, by the way) which can win it only a method of "brute force", and that — not always the gain is so great, predictably. Thus, when functionality of scientific notebook software an old drive has enough, it is frequent more reasonable it will appear to try to keep it, rather than at a upgrade to search for model with the new interface, at all replacement murder will out on soap differently will turn out. And the basic conclusion within the limits of our testing is those — application of external boxing even does not limit high-speed stores. You can easy write down disks for the speed 12-16h irrespective of, the drive inside of a computer is established or is connected by the external interface (only consider, that in this case it is necessary to take care and of a defragmentation of files as Mb per second figure already enough serious). Frighten a little, unless, fluctuations zapolnennosti buffers. But scientific notebook software up to zero of figure do not fall, and if have fallen — now it not so terribly (somehow that Plextor after attempt of reading of the killed disk has fallen down in PIO-rejim, and I, not having noticed it, has decided bolvanochku to burn — process has borrowed hour an one and a half and went with greater pauses, but the main thing — the result has turned out quite normal :)). The latest connection ND-3550A is direct to IDE-kontrolleru has shown, that it concerns to it «bagoficham», instead of to features of the bridge in Smart-kabele more: and in scientific notebook software this case the buffer, let also was not devastated completely never, but to fall approximately up to % (that is, as well as in « external execution ») sometimes is capable Total As we have found out, with the problems the mentioned container from ViPowER consults, really allowing to use optical stores in that case when in the case there is no place or on parent payment PATA-kanalov. And, it consults and in case of the newest high-speed drives, let alone a case when there is a desire to continue use something old and checked up by time. Thus cost of boxing is rather insignificant — in area of dollars (I did not begin to use our technique for the instruction of the scientific notebook software prices as VP-6029V from the market already leaves, and VP-60 on it has not come yet so the mess can turn out) so totally even at purchase of a new drive it is possible to be entered easily in one hundred dollars, and about use of already available equipment I am silent :) And as in VP-6029V myself will feel the winchester, we shall talk hardly later.
