Winchesters on Gbytes. A part 3. Samsung HD080HJ, SP0812C and SP0802N
In the third part of our review of modern hard disks in capacity of Gbytes we shall consider popular models from Samsung Electronics, attractive not only low by and the mark untwisted for some years, but also a combination of modern technologies and interfaces in last updated models. I shall remind, that earlier we have already considered original series of disks and, designed specially for the given segment of the market, in comparison with similar models from Western Digital and Maxtor.
Series Samsung SpinPoint P has appeared in the market very much for a long time to measures of the modern computer industry in the middle of 2003. Also it has fujitsu s7000 notebook turned out so successful, that continues to remain on plavu till now. The blessing, density of record about Gbit on kv. Inch that corresponds 80-gigabaytny'm to three-inch plates, became an original stumbling-block, overcome which manufacturers could not long enough. And even having overcome, continued and continue to let out successfully till now winchesters on checked up by time and reliable 80-gigabaytny'h plates as typical needs of the modern consumer are those, that hard disks even on one such plate are capable to serve a modern budgetary computer quite adequately.
Having begun series SpinPoint P with UltaATA/133-modeley with the buffer of and Mb, koreycy' have soon added to them and model with support fujitsu s7000 notebook of interface Serial ATA 1.0, and later, already in the middle of 20 have renewed this series younger models with faster (on skorsti linear access) magnetic plates of new generation and the new controller with support of interface Serial ATA II with speed of data transmission Gbit/s, Native Command Queuing (NCQ) and Staggered (Delayed) Spinup (consecutive promotion). In passing having passed and on a new designation of the disks: if earlier SATA-model' carried the name, for example, SP0812C novelties began to be called, for example, HD080HJ. That is now figures designate only capacity in gigabaytah, two letters before figures designate a class (H — rigid a disk, M or D — mobile or desktop accordingly), the letter after figures designates quantity and type of heads (L=6, J=4, I=3, H=2), and last letter designates fujitsu s7000 notebook a series of disks and the interface.
Disks Samsung of series SpinPoint P80: HD080HJ (above), SP0812C (in the center) and SP0802N (below).
Which instead of the former decision with separate chipom-serializatorom interface Marvell 88i80 began to use the integrated controller of new generation Marvell 88i65 with support Serial ATA II as well as in stores Samsung which have appeared approximately at the same time of a series.
Payments of controllers of disks Samsung of series SpinPoint P80: HD080HJ (above), SP0812C (in the center) and SP0802N (below).
However, to save a place and to make a payment of much more compact koreycy' thus for some reason were afraid, unlike of some competitors.
The fujitsu s7000 notebook basic passport characteristics of considered disks are presented in table 1.
Table 1. The basic characteristics of hard disks in capacity of Gbytes.
In updated 80-gigabaytnoy models HD080HJ of series SpinPoint P (which to us it is now most interesting) in comparison with predecessors of the same series has exchanged not only the controller and the interface. With 7 up to 8 Mbit/s the maximal speed of linear reading has increased (due to transition to the plates made on new technology it is similar 1 and 125-gigabaytny'm to plates Samsung), noise of rotation (with up to dBA) and e`nergopotreblenie in a mode of rest fujitsu s7000 notebook (idle) with 7, up to 7, watt for SATA-modeley (however, UATA-modeli Samsung consume even less) has in passing decreased. Other passport parameters of stores have remained at the same level.
Original rubber legs at cases of models Samsung, as usual, are present.
On label UltraATA-modeley the applicability of jumpers is in detail painted, and new SATA-model' allows to choose a jumper speed of the interface of 1 or 3 Mb per second (NCQ in both modes it will be supported).
SATA-diski Samsung are deprived a feed through socket Molex so at a upgrade them of old systems it is necessary to buy in addition an adapter of feed SATA.
Stores Samsung are traditionally delivered in plastic udarozasch'itnoy to packing and completed with a unpretentious management on installation and, attention, a set of fixing screws, and also the crosspiece on pin-djamper.
Interface UltraATA/133, Serial ATA 1. or Serial ATA II ( Gbit/s, NCQ) fujitsu s7000 notebook Fluid Dynamic Bearing Spindle Motor Technology
I shall remind also, that the designation of models of hard disks Samsung (see above) not so long ago was replaced.
Following disks in volume of Gbytes (everyone have on heads) take part in tests:
Samsung SpinPoint P HD080HJ (Serial ATA II, Mb),
Samsung SpinPoint P SP0812C (Serial ATA 1.0, Mb),
80-gigabaytnikov we shall consider the remained representatives of modern series in following parts of our review.
For check of work NCQ the controller on chip Silicon Image SiI3124-2, established in PCI-slot the specified parent payment was used.
Disks were rigidly fixed on metal the chassis of the case of the system block and connected to controllers of interfaces UltraATA/1 and SerialATA 1. bridges ICH on a parent payment. The basic winchester was "master" on the first channel of the controller of a chipset, and the fujitsu s7000 notebook examinee a disk was connected by "master" on the second channel of the same controller. Additional heat removal from disks (special coolers and fans) it was not carried out. Before testing disks got warm within minutes start of the program with active casual access.
Tests were spent under control of operational system MS Windows XP Professional SP1. Winchesters were tested as not marked on sections (in tests Intel Iometer, H2Benchw and AIDA32), and broken and formatted by regular means of operational system depending on a kind of the test: one NTFS-razdelom the greatest possible capacity for tests of average time of access and removal of the schedule of speed of reading in WinBench and two equal sections NTFS or FAT for other fujitsu s7000 notebook tests (WinBench Disk WinMark 99, copyings of files by various patterns, test ATTO Disk Benchmark, the test mnogopotokovogo chteniya/zapisi Nbench 2. and the test of speed of disks in program Adobe Photoshop). Sections NTFS had the size in half of volume of a disk everyone (that is the second section began exactly with second half of disk), and sections FAT had the size on 327 Mb, and the first began in the beginning of a disk (on the "fastest" paths), and the second — is equal from the middle of a disk on volume. The size klasterov NTFS and FAT got out by default — and Kb accordingly. For definition of physical characteristics of disks (average time of access, speed of the interface and linear speed chteniya/zapisi plates) tests AIDA32, H2benchw and WinBench were used. fujitsu s7000 notebook For an estimation of the general productivity we use numerous patterns in Intel Iometer, quite good test C'T H2Benchw, work with a disk of program Adobe Photoshop, mnogopotokovy'e reading and record of files and conventional WinBench (though we not so lean on last in conclusions as optimization of disks and controllers under it has repeatedly been noticed).
First — schedules of speed of linear reading for disks (click on them to look full figures).
At the analysis of schedules for disks Samsung first of all attracts attention change of the approach for adaptive formatting. If earlier (at initial 80-gigabaytny'h plates Samsung) steps with the different density, numbers of a zone periodically changing in process of growth at HD080HJ we see the smooth schedule with fujitsu s7000 notebook traditional to steps of zones were observed. However, by the analysis of last disks Samsung of greater density, adaptive formatting is present here again, is simple in the advanced kind, with adaptive border of zones and more "intellectual" compiler of the logic addresses, allowing to smooth roughnesses of the schedule.
On the maximal and average speed of linear access Samsung HD080HJ it has appeared noticeably better the predecessors and has overtaken all competitors on 80-gigabaytny'h plates though former 80-ki Samsung of high speed could not brag (and they, by the way, till now actively are on sale in shops).
On speed of work of interface Serial ATA disk HD080HJ has appeared far not fujitsu s7000 notebook the quickest, having conceded in even to senior brother SP0812C. However, application of the system chipset of controller SATA built in the southern bridge II is capable to eliminate this injustice, having lifted real speed of interface HD080HJ almost up to 2 Mb per second.
On average time of access Samsungi cannot to argue, certainly, with leaders from Hitachi and ExcelStor, but nevertheless there are little bit more quickly, than disks WD and Maxtor. However, here there is one difficulty.
The matter is that stores Samsung support hardly more complex, than usually, the scheme of management acoustics and in the speed of search. Traditionally Samsung appoints three different modes of search with use AAM (and it is present in specialized samsungovskoy to the utility for management of acoustics which, unfortunately, is not present in an easy approach): fast search, average search and silent search. fujitsu s7000 notebook And last is activated, when in register AAM is registered 00h! Other manufacturers do not use this zero value, therefore, for example, the same universal Hitachi Feature Tool simply does not understand this value of register AAM (probably, will understand in the future versions). And so, the difficulty has appeared that if models SP08x2x are delivered « in a mode of fast search » new store HD080HJ taken in the channel has appeared preestablished in a mode of the most silent search (AAM=00h), whence its any usual means to deduce it was impossible. Therefore we ottestirovali this disk in deflotnom (by delivery) a silent mode of search on different controllers (with NCQ and without), and as a bonus, especial image having translated it in a mode of fast search — once again with controller ICH5. I shall tell on a secret what to deduce this disk from a stupor fujitsu s7000 notebook (that is from a mode of silent search) besides inaccessible mere mortals utilitki Samsung can be helped by program HDDLife which allows to operate with values AAM below 128dec. However, as it has appeared, tired out in a mode of silent search HD080HJ it has appeared at all in vain as in a mode of fast search its noise on value judgment noticeably exceeded those for all other investigated by us 80-gigabaytnikov, including former samsungovskie. That is it "cracked" on active search rather loudly.
Now we shall estimate an overall performance of algorithms of the postponed record firmware a disk and ke`shirovaniya written down data in the buffer of a disk fujitsu s7000 notebook on falling an average of time of access measured by operational system at record concerning reading at included write-back ke`shirovanii the store.
Ahead here models Hitachi and ExcelStor, and for disks Samsung the given parameter ke`shirovaniya records has appeared not at height, though on the average and better, than at disks Maxtor and WD. And, new model HD080HJ differs the best characteristics in comparison with predecessors.
Let's pass to tests of productivity in appendices and all over again we shall look, how much disks are optimized for mnogopotokovoy works. For this purpose I traditionally use tests in program NBench 2. where files in the size of 1 Mb enter the name on a disk and are read from it by several simultaneous streams — both is close, and far otstoyasch'imi from each other on a disk fujitsu s7000 notebook (in this case it is used FAT32). On the first diagram the results average on several patterns for reading and are shown only to record, and below diagrams in detail are resulted.
At mnogopotokovoy records of the leader traditional before from Maxtor easily advances new disk Samsung HD080HJ though former SP0812C and lags behind. If we shall recollect, that at koreycev differed excellent parameters in this test becomes clear, that kid HD080HJ has inherited from them not only the controller, but also the best algorithms firmware.
Thus it appears, that HD080HJ also the best and in mnogopotokovom reading, obviously having overtaken former leader WD800JD. And, in a mode fujitsu s7000 notebook of silent search it even is hardly faster, and use NCQ in this case strongly ruins productivity.
In popular tests Disk WinMark from package WinBench new SATA-disk Samsung again takes a palm tree of leadership, both with NCQ, and without NCQ.
It is necessary to note, that former SATA-model' SP0812C in High-End-teste obviously concedes to the majority of the competitors with the same size of the buffer.
In a disk dough of popular package Futuremark PCMark all stores from Hitachi, ExcelStor and WD, however Samsung HD080HJ smog-taki to interfere with traditional dispute, in a mode with support NCQ having added in this test already % (at ExcelStor NCQ here has added only % of productivity). And, that is surprising, — in a mode of fujitsu s7000 notebook silent search!
And younger UATA-model' Samsung here itself conducts not too badly, competing with Hitachi.
In similar test C'T H2benchW where influence NCQ is not shown, upwards with the minimal advantage takes Samsung HD080HJ in a mode of fast search whereas in silent search it, as well as in PCMark04, loses much. But younger SP0802N here obviously is faster than the soprenikov from Hitachi and ExcelStor and almost catches up Maxtor 6Y080P with four times about l'shim the buffer.
But on speed of work of disks with a time file of program Adobe Photoshop disks Samsung cannot brag of outstanding results, and SP0812C so in general has shown unexpectedly low parameters. Tests in Intel Iometer
Though considered stores hardly can be considered seriously as a basis in the slightest degree a powerful server, testing in server patterns all of us we shall lead fujitsu s7000 notebook — for reception of the general picture. Traditional widespread patterns DataBase, File Server, Web Server and Workstation here are average by us on final diagrams, without detailed elaboration. Averaging was spent vectorially without weight factors in all turns of inquiries.
In a mode of fast search (and without it here in any way) disk Samsung HD080HJ could even overtake a little SATA-diski Hitachi and ExcelStor though older models Samsung act here more modestly.
The small prize from application NCQ with controller SiI31 at HD080HJ here is by slow search.
Now — our patterns for IOmeter, closer to destination to users of usual desktop personal computers. At imitation of casual record of large files (type mp3, video, greater photos and so forth), as well as earlier in test NBench, forward leaves Samsung HD080HJ, advancing even disks Maxtor, traditionally strong in the given problems. fujitsu s7000 notebook Thus former stores Samsung show the worst parameters in one and a half time! However, the stick has appeared about two ends, and at reading large files HD080HJ it appears in the end of the list, having conceded even to the predecessors.
The similar picture is observed and at chtenii/zapisi fine files to casual addresses within the limits of all physical disk though leadership is grasped confidently already with winchesters from Hitachi and ExcelStor, and samsungi are amicably restricted in the bottom half of list.
And here at imitation of copying of files to casual addresses within the limits of all disk we, as well as in case of with Samsung SP2504C, are convinced of their fantastic optimization firmware under the given type of problems — model HD080HJ in any variant of application does not allow anybody any chances to come nearer. Though former models fujitsu s7000 notebook Samsung act here firm serednyachkami.
As a result, by results of geometrical averaging six previous patterns (reading, record and copying of files to casual addresses) at depth of turn from up to only due to the test of copying forward with appreciable otry'vom leaves Samsung HD080HJ in a mode of fast search though and in a mode of silent slow search it behaves rather not bad among loud competitors! Surprises here (as well as in test Photoshop) appreciable backlog of the first SATA-modeli Samsung SP0812C.
At imitation of a defragmentation the leader former (who would doubt), and other two disks Samsung — in seredinke.
At last, in a pattern potokovogo simultaneous chteniya-zapisi large or fine blocks disk Samsung fujitsu s7000 notebook HD080HJ shows fantastic results on fine blocks (it is again recollected SP2504C) whereas on large blocks its speed leaves much to be desired, conceding even those at old stores of this manufacturer, any more not speaking about disks WD and Maxtor.
In general, the "average" information in this tablet very much reminds notorious average temperature on hospital proceeding from which the diagnosis this or that patient to put slojnovato. :) Especially if to consider, that the buyer usually goes to that shop, where the prices for an interesting product below.
Budgetary models of hard disks Samsung of series SpinPoint P as it has fujitsu s7000 notebook appeared, have shown enough wide scatter of parameters of productivity. If former disks (development actually 2003) with the old controller, firmware and 80-gigabaytny'mi plates especially not blesch'ut on a background of competitors, losing them in the majority of tests new model 20 Samsung HD080HJ with the integrated controller Serial ATA II originally optimized firmware and updated, faster magnetic plate shows, at times, fantastic results in a number of tests and is for today one of the fastest in desktop problems model in capacity of Gbytes. Besides this model possesses also one of the smallest among analogues in noise level of rotation (see specifications), excellent shockstability, small enough thermal emission and, that is important for disks in capacity of Gbytes, — traditionally low for stores Samsung by. In general, Samsung HD080HJ, probably, one of the best at present desktop winchesters of small capacity. For what it is not a shame fujitsu s7000 notebook to it to award our award « For original design » though and upakovka/komplektaciya too is worthy to be noted.

The Golfing Greats - Arnold Palmer
Arnold Palmer, General of Arnie ' s Host, was eloquent of golf, but he could obtain disused describing his separate breath before long he oral, " Success fashionable golf depends less onward g6computer health of trunk cadaver than upon lustiness of computerless marbles and reputation.
