One-standard kartovod Pretec microSD Card Reader and cards of memory microSD from A-data and GOODRAM
Format MultiMedia Card was initially developed as the most compact fle`sh-carrier specially created for needs of multimedia household electronics (as it is reflected in the name) in a counterbalance to cards for more bulky phototechnics. However, in due course original MMS parts of manufacturers became less interesting, why in the market there were cards Secure Digital. From "primogenitor" they have inherited small length and width, "have a little grown stout", however, despite of last circumstance, long time remained one of the most compact fle`sh-cards in the market. It seemed, that greater and to wish there is no sense. However general miniaturization has led to that "original" MMC and SD have asus a6000 notebook appeared too greater. No, certainly, and now they can be pushed" into a player or a mobile phone, let alone kommunikatore, however manufacturers of the last for the sake of it should go on the certain cunnings. For convenience of embedding slota in portable technics, the sizes of cards it was necessary to reduce even more strongly. First steps on this way of steel miniSD and RS-MMC, however and it it has appeared a little. More precisely, it is a lot of. Obvious steps on a way of reduction of the sizes became the cards offered by company SanDisk. It is asus a6000 notebook necessary to note, that already at the first stage when the format was something like the intrafirm standard, SanDisk it was possible to convince to pass to it some manufacturers. In particular, it has appeared those Motorola — for that moment the second-largest manufacturer of mobile phones within the limits of world deliveries, and in the market of the USA if I am not mistaken, the first. At such support of a card have been doomed to popularity, and it was not slow to be to them as soon as the SD-association has accepted the standard as interbranch under the name microSD. The MMC-alliance some time has asus a6000 notebook given on it the symmetric answer in the form of the cards developed Samsung, and similar parameters on the majority back, but speech today will go not about them. As company Samsung in many products uses microSD, no less than Motorola many other things continues to prefer them, and firms too. Tiny microcards have a number of the certain lacks, being continuation of their basic advantage, - the size. For quite clear reasons to achieve the big capacity from more voluminous card with a greater pressure of a feed is much easier, than from as much as possible compact: it is possible to place inside of the case of more microcircuits of fle`sh-memory. For this reason while even announcements microSDHC it is not asus a6000 notebook observed — not all manufacturers have managed to master accessible within the limits of SD 1.x officially two gigabayta. At the same time capacity SDHC is already cunning up to Gbytes (at least, such cards already are declared by many), and miniSDHC — up to Gbytes. However, HC-cards can be applied only in the corresponding equipment so to the majority that microSD on Gbytes all the same rather actively appear in the market that equalizes actually users of all updatings SD (non-standard "full-size" SD on Gbytes separate conversation — all the same they non-standard so their use can quite cause a number of problems), probably, is more important. The second lack of the small size is... As it is paradoxical, the size. Yes, microminiaturization is convenient to manufacturers a host-devices, but users frequently forces to refuse such asus a6000 notebook important feature of fle`sh-cards as working in shifts. Really — and where to store the card taken from the device? How for it in case of need to search in things? How such krohu, in the end-ends to establish in « field conditions »? However and many are quite ready to go through this lack – the huge quantity of users gets only one card. The some people never take it from the device — unless at replacement of more capacious. And manufacturers in stationary with an opportunity of replacement too with might and main promote this process of transformation of the replaceable carrier: in very many phones, for example, slot for cards it is located in such a manner that asus a6000 notebook for installation/extraction of a card of memory it is necessary to switch off not simply a mobile phone, but also to take it to pieces (to remove a back cover and the accumulator at least). On the other hand, sometimes to take cards all the same it is useful — for reading and record of the information. Certainly, for this purpose it is possible to use opportunities a host-device, but it always is appreciable more slowly, rather than by means of specialized kartovoda. And sometimes and very slowly, or it is dear: when the cable besides to phone in the complete set is not present also it asus a6000 notebook it is necessary to buy for separate money (and after change of phone, probably, it it is necessary to throw out), and from universal interfaces any brake, type Bluetooth is accessible only. The given report and on a paper is sluggish — speed is estimated in units megabit a second, moreover and practical realizations quite often add "pleasures" therefore data transmission through VT can quite go for the speed e`tak to Kb\ss. That by'stren'ko podredaktirovat' a telephone directory or to leave in the Internet, normally. But zakachivat' on such speed even one hundred mbyte of music... Can calculate, how much given process "is pleasant". And in fact capacity of cards, I shall remind, has reached already gigabaytny'h sizes! Hence, the fast asus a6000 notebook interface between a card and a computer is demanded, means, are necessary and kartovody' with support microSD. Basically, it is possible to manage and special support — having taken advantage of full compatibility of cards with SD at a logic level therefore only simple passive adapter is required, but also here there are the "but". First, last is usually applied only on Retail-versions of cards of memory — in case of applied on the device (and and in this case speech often goes about one hundred-other mbyte) the knowledge of existence of adapters will not help you, yet we shall not get a card with those. Secondly, it is inconvenient. It is simply inconvenient. For it is complex: to pull out a card from the asus a6000 notebook device, to thrust in the adapter, to thrust the given design in kartovod, upon termination of process to do all actions upside-down. In view of time expenses in case of not too capacious card it can turn out so what more quickly nevertheless to take advantage of a cable for communication with a computer a host-device. Even in the event that with extraction of a card from the adapter there will be no problems, and they happen rather often: cards are very compact, to be hooked practically there is nothing. Special sloty' for microSD have appeared not yesterday and not the day before yesterday, but also till now with «nativnoy» support of these cards not and it is a lot asus a6000 notebook of devices (while work with miniSD without an adapter actually became a standard opportunity modern kartovodov). We today also shall consider one of them. Pretec microSD Card Reader one-standard kartovody' it is enough for a long time also have densely registered in the list of production of the company. Especially they are actual just for small "telephone" cards: to carry with itself constantly big mul'tiformatnoe the device it is not interesting, and compact odnostandartnik it is possible and in a pocket for emergency to put. And today at us on studying the next such store from Pretec (earlier we have studied calculated on full-size cards SD/MMC so in something universal, and, and also for MemoriStick Duo). Nothing reminds the device? Means, you inattentively read last clauses (references on which above) asus a6000 notebook :) For a basis have been taken successful enough design e-Disk II, allowing the store to look in the same way, as usual USB-fle`shdrayv. The positive moment is that kolpachok, a closing socket, to lose it will not be possible — hangs on shnurke when it is opened. And slot for cards disappears under a "leaning back" cover in a back part of the store. Considered today kartovod from base model differs unless in the sizes and a little bit modified slotom for cards (for quite clear reasons) and all. Is not any modern revelation and the applied controller — according to VID/PID, it Alcor Micro AU63 (or its clone). Old enough microcircuit with support MMC, Memory Stick Pro and SD, applied in the first e-Disk and its analogues. In view of the respectable age, the given controller does not support last updatings of formats. And, if only asus a6000 notebook four lines of data in case of MMC 4. in this case are unimportant (the given cards physically are not supported) restriction SD 1. is already worse: means, the maximal speed only in area of Mb per second. However, running forward while it cannot serve as restriction — manufacturers of cards all the same do not pass on 1.1. Whether will be in the future? Not necessarily. A host-device, calculated on microcards, of high speed of work with them cannot brag. And in case of data exchange with a computer by means of kartovodov at present volumes of cards on double (in the theory) a difference in speed it is possible to give up as hopeless — asus a6000 notebook not fatally. Most likely, microSD will jump with 1. at once on 2.0: there both speed above, and volumes supported too. As soon as old controllers will cease to be delivered, and will jump. For now corresponding specifications of 1. microcircuits cost more cheaply, them with might and main and use. For new cards be required both new devices, and new kartovody'. It is necessary to note, that data kartovod any more is not the senior model from Pretec — already in it (on CES 2007) the company has presented year. The given model applies for a rank of the most compact in branch of the device (the sizes only x x mm), and very much can be, that supports asus a6000 notebook already SD 2. (anyway, announced then i-Disk II/i-Disk II Plus, come in the stead e-Disk II/e-Disk II Plus accordingly, from primogenitors differ support of last specification). But while novelties exist only in the form of the announcement dated for the largest exhibition, and several samples, on it shown so when they will appear on sale even difficultly to predict. And microSD Card Reader if necessary it is possible to find in sale already now, and it at rather compact sizes already now will provide to you support microSD without any adapters. However, only their one — a payment for simplicity and compactness. Accordingly, for needs of testing I had to look and suitable cards, the blessing and questions on their speed of work are not present-is not present, and arise. For asus a6000 notebook cleanliness of experiment two cards have been taken, we shall get acquainted with them more in detail. A-data microSD GB Popularity of production A-data, despite of some arising while in service separate representatives of given production of a roughness, in our country is high enough, and the given segment of the market has even more strengthened it. The matter is that, first, A-data one of the first has begun deliveries of cards in capacity two gigabayta, and secondly, one of the first has begun their deliveries to Russia, essentially having outstripped overwhelming majority of competitors. As I have told above, such capacity for "classical" cards of the given type, most likely, will appear limiting therefore many users had quite reasonable temptation to get at once such card, then to not think — enough it of memory or asus a6000 notebook its volume it is better to expand: All the same there is no place to expand already :) At a today's price level this quite reasonable decision, and in general — the prices on fle`sh from A-data always were rather democratic. Accordingly, the cards similar tested us, were bought up and bought up actively enough. Complete with a card there is also an adapter, allowing its use in the technics calculated on "greater" SD. However, in case of technics it is not absolutely justified — the full-size card will manage more cheaply, and with various kartovodami this adds compatibilities. However, it is a little popol'zovavshis' the card and the adapter, I on own experience was very well convinced that devices with direct support microSD are extremely necessary. The matter is that a card flat enough — "inflow" in the top asus a6000 notebook part (to which it is necessary to cling to take it from slota or an adapter) it is swept hardly up, and in photos it is absolutely not visible. In this connection it is very difficult for seizing fingers, and in the adapter the card sits very densely. Thoroughly having impaired a little a nail already at the first attempt to take a card from an adapter, I have understood, that in practice hardly began make often such procedure — very much it is tiresome. And at presence in an arsenal of the user of the device similar Pretec microSD Card Reader, from this Chinese torture it is possible to be free. As it is possible so dearly, as convenience of use... Conclusions are obvious :) GOODRAM microSD GB In spite of the fact that company Wilk Elektronik S.A. (the owner of trade mark asus a6000 notebook GOODRAM) has borrowed in fle`sh-memory only in 20 (before the firm of years specialized exclusively on operative memory), at us on testing one of its fle`sh-products, - fle`shdrayv GOODDRIVE has had time to visit. The turn and microSD-cards Now has come. Volume of tested model "classical" — if dvuhgigabaytny'e updatings many manufacturers have mastered only to the beginning of this year, and that yet everything gigabaytnaya the mark has been passed much earlier (though and too, by and large, not so long ago — and year has not passed since such cards have started to be issued massovo). However, in the market of any stores "capture" of new top does not mean uteryu a urgency production of smaller capacity — as a rule, the best parity « dollars on unit of capacity » at all at topovy'h on capacity asus a6000 notebook of products, and it is far not all the maximal volumes are necessary. As well as in the previous case, the card is delivered together with an adapter. Impressions of use of the given accessory much more pleasant, than have remained after A-data. The reason of it is well visible on skane a face sheet of a card — here rather precisely expressed inflow which is easy for picking up a finger, a nail or any else subject. It will affect, for certain, not only at use of the adapter, but also at extraction of a card from many devices. So at purchase I advise to pay attention on such, like insignificant subtleties — it seems, that a trifle, but in case of unsuccessful design of blood it can spoil much. A technique of asus a6000 notebook testing Experience of application "full-size" kartovodov series e-Disk has opened one of their lacks, - problems of compatibility with the some people a host-controllers. On this raker I have come also, the blessing the basic test stand already almost year is supplied by a parent payment on nForce SLI. Faults of company Pretec here are not present — a problem of compatibility with realization of trunk USB in chipsets NVIDIA nForce3/nForce - "merit" of old controllers Alcor Micro. For the sake of justice, arise problems even with the given chipsets not always, and with other (from Intel or VIA, and with more modern microcircuits NVIDIA asus a6000 notebook too) are not noticed absolutely not, but the fact remains the fact. And I the next time with it have collided, therefore testing was spent on two computers with a different hardware configuration. At the same time and for comparison it has been taken two stores as internal Apacer to rearrange it would not be desirable (plus and as cards interest us not to a lesser degree, it was interesting to look at how they of will messages on the different equipment). A configuration ¹1: EpoX 8NPA SLI on the basis of chipset NVIDIA nForce SLI AMD Athlon 32 + (512K L2) Gbyte RS32 DDR SDRAM system winchester Western Digital WD16 JS Kartovod Apacer Internal Card Reader AE1 (on Alcor Micro AU6375) the Configuration ¹2: ASUS M2NPV-VM on the basis of chipset NVIDIA GeForce 61 (northern bridge GeForce 61 and southern asus a6000 notebook nForce 430) AMD Athlon X 36 + Gbyte RS 54 DDR SDRAM system winchester Western Digital WD740GD Kartovod Apacer Mega Steno AM2 (on Genesis Logic GL819) As to the software on both computers it has been established Windows XP Pro SP2, and for measurement of parameters of examinees program Lavalys Everest Ultimate Edition 20 2.80, more truly, the test of disk stores entering into it was applied. Tests of data reading it is well appreciable, that in both cards the controller on speed of work corresponds to a level of specifications SD 1.0. However, at a good level — actually cards quite could receive marks 66h, that not so long ago was the best for asus a6000 notebook SD result. Distinction in speed between cards is, and on all three kartovodah, however the smallest, so in practice by it mojBut also to neglect. Even in the most unsuccessful case (on nForce4) odnostandartnik from Pretec only slightly concedes in speed of work to competitors on the advanced controllers so use concerning an old microcircuit is quite justified. Here problems of compatibility kartovoda with a chipset are visible very well. However it is necessary to clean a weak part (in the form of nForce SLI), and its results noticeably improve, let and do not allow to keep up with modern competitors. As to cards the difference between GOODRAM is well visible and A-data — such asus a6000 notebook distinction in time of access can easily be shown and in practice in the device. Though if a card to use for storage of music in ¬»¬/PHONE it will not be shown. And if to speak about processing a plenty of fine files — it is easy. Tests of data recording the Picture is similar to the speed of reading received at testing, with that only a difference, that value of speed is much less — approximately twice. However cards again almost equally conduct themselves. And in view of rather low speed of work with them in the devices which are distinct from kartovodov, it is possible to asus a6000 notebook consider similar results quite normal. And to use a card instead of full-size updating somewhere in the digital camera of the big sense is not present: many modern models CFK are capable of greater. The strange has appeared different behaviour of cards in this case. On both computers and with all kartovodami the card from GOODRAM has shown about equal time of access at record — even in the worst case it has increased slightly. And the disorder for a card from A-data is great enough. And in absolute values its results are worse, but, in view of the previous remark, in relative calculation the difference varies from the minimal and poorly appreciable %, up to quite osch'utimy'h % (even if to not look at a unsuccessful sheaf from nF and AU6331). The prices In the table further are resulted three devices tested today, actual at asus a6000 notebook the moment of reading of the given clause by you: Pretec microSD Card Reader A-data microSD GB GOODRAM microSD GB $ (4) $ (4) N/D (0) Total Summarizing we shall begin with cards. It is simple to notice, that while the maximal capacity microSD has reached or nearly so has reached similar for larger updatings cards, about high-speed parameters of it you will not tell. Whether it is true for other representatives of the given class of carriers? Or it to us so "has carried" with today's examinees? Whenever possible, in due course we shall check up, however while I nevertheless tend to the first variant. All the same two cards obviously made by the different companies at different factories, behave equally – already much. « In the same heap » it is possible to send in advance one more model asus a6000 notebook — by that SanDisk microSD carries the to family Ultra II where models with a speed less than Mb per second enter, and it will show the same to us. All this, together with some higher by tiny cards, does their application in a role of a substitute full-size SD unjustified. Unique plus of such approach is greater universality of purchase — will approach to a lot of the equipment that can affect if there will be a desire/necessity to change that device for which the card is at the moment got. However presently active changes in the market to be pawned on prospect of sense is not present is the best way to punish financially ;) And in the devices initially calculated on microSD, both cards tested today will be quite on the place — asus a6000 notebook shown speed of work will suffice with a stock, the volume is great enough for all problems which usually solve on devices with slotami such type (kommunikatorah, smartfonah or phones). As to next one-standard kartovoda Pretec, that, unlike the data carriers, the necessary equipment it is not: always it is possible to take advantage of opportunities a host-device for switching with a computer, and in some cases — the adapter for a card of memory and any store with support of full-size SD-cards. However both the first, and the second is less convenient. In the first case speed of transfer of the information much more below will be, and the additional equipment, probably, all the same to asus a6000 notebook get it is necessary (and very much can be, that more dear, rather than kartovod). In the second case inconvenience is, at least, the adapter. And, if to speak about two cards tested today, in case of model from GOODRAM it does not deliver superfluous inconveniences (except for necessity to insert/take out and somewhere to store a card the adapter when it is not necessary) on a regular basis to use it together with a card from A-data … to tell the truth, I long would not sustain :) And kartovod all the same though any it is required. Thus, the idea of creation of specialized compact model with support microSD is asus a6000 notebook quite reasonable. As purchase those is reasonable also. The only thing — possible problems of compatibility not on a hand microSD Card Reader, but here it can't be helped (anyway, before occurrence on sale i-Disk Micro Reader). Well though, that the given problems arise only at use together with pair chipsets, and that not in 1 % of cases.
Kartovod it is given on testing by the company of the Card of memory are given on testing
