Hard disks with interface SCSI in 2000. July.

September 5, 2000



Traditionally SCSI disks were considered to be intended for the class High-End however recently some fall in value and the high level of tasks fulfilled on usual PCs increase interest to them. The development of multimedia, digital video and DVD has required from drives not only large capacity (for example MPEG2 of high quality on usual CDROM will be only 20 minutes and the source film occupies up to 200 GBytes) but also increased speeds - one stream of source digital video requires approximately 20 MBytes/sec. Certainly today IDE hard disks have appeared and they are not a match by speed for SCSI and even IDE RAID controllers. It has mined positions SCSI (even AMI and Adaptec have released their IDE controllers!). But we shouldn't forget that SCSI today provides speed up to 160 MBytes/sec and capacity more than 1000 GBytes on one channel. IDE won't catch up with it by these parameters soon. Thus for systems with necessity of such speeds and capacities there is no alternative. Just don't forget to keep a lot of money.

As for speed where one of main metrics is a rotation speed, first SCSI disk with RPM 7200 was represented in 1992 then in 1996 Seagate presented revolutionary 10K RPM Cheetah. And then in 4 years the first disk with RPM 15K Cheetah X15 was announced. And all this progress at first came to the market of SCSI disks. Even the first ATA model with RPM 7200 appeared only in 1997 later than SCSI Cheetah.

The development of interface SCSI also didn't lag behind. We have already written about its last versions - Ultra2 SCSI and Ultra160. The standard Ultra3 (ANSI SPI-3) covers some innovations. The manufacturers first used a little bit capsule version called Ultra160 MBytes/sec SCSI and it used three innovations from five provided ones: 160 MBytes/sec transfer rate and double transition clocking (data transmission on both fronts of clock signal), check CRC and domain validation (supervision of environment). The modern disks (Quantum, IBM) already use a complete variant which includes Packetization and Quick arbitration select (QAS) except three ones named above. These technologies are directed to optimisation of control SCSI bus, lessen delays at command passing and protocol overhead. Let's note that there is also some mix-up in titles - SCSI-3, Ultra3, Ulta160/m, Ultra160 however it is not so terrible as all implementations SCSI-3 are compatible by definition. More problems can be caused by selection of SCSI controller as it is unknown what exactly is realised for example in Adaptec 29160, a manufacturer has only a mention about 160 MBytes/sec speed and domain validation. So it seems that controllers lag behind hard disks and for complete usage Ultra160 it is necessary to wait their second generations. Besides Ultra/160 is completely inversily compatible with Ultra2 and provides in this mode operation with speed up to 80 MBytes/sec. You can read about Ultra160 in detail on http://www.ultra160-scsi.com/.

In the tables you can see master data of hard disks which are fighted for. Except high-speed metrics they are: physical size of the disk - height, noise level, power consumption and stability to external mechanical effects. The data are indicated only for models with traditional SCSI interfaces. For released variants with Fibre Channel buffer and power consumption are usually more. Let's note that as the procedures of parameters measurement can differ for different companies, then the matching of disks by this data is not absolutely correct. It even happens that for the same model different figures can be resulted in different documents. Therefore we have made testing some models of hard disks in the programs Winbench 99 and Adaptec ThreadMark 2.0. In spite of the fact that the testing was effected on the controller which maximum data transfer rate by SCSI bus reaches only 40 MBytes/s (more exactly Ultra2 the controller was used in UltraWide mode), none of tested disks reached read rate from surface up to this rod (except one represented the last. You can read about it in detail below. For reliability we have compared operation of fast disks in UW and Ultra2 modes, thus the difference in the tests Winbench 99 has not exceeded 2%. Certainly at usage more than one disk on the channel usage Ultra2 is more appreciable and justified. As for the configuration of PC it is the last tests which are done on UWSCSI controller and processor Celeron (SuperMicro P6DBU, Celeron 450, 64 MBytes RAM). Faster controller and processor Pentium III will be used in the following testing. For the latest models of disks it was necessary to change the parameter of the test Winbench 99 Disk Inspection CPU Utilization Test Transfer Rate from usual 4000 thousand byte per second up to 20000. Also some tests on new disks simply did not work. Besides some results seemed to be strange - for example speed 68300 MBytes/sec in the test FrontPage can seem but we shall keep it on conscience of the developers of the tests and we shall look for the new one.

Quantum

Quantum for the series SCSI disks already for a long time uses a title Atlas and probably is not going to change it. Such conservatism simplifies a finding of particular model as against Seagate and IBM which name the disks using 2-3 titles at the same time. Production of Quantum is often advanced both by possibilities and on speed (though the first 10000 RPM disk was released by Seagate). As for subjective impressions there are no claims to production Quantum either on speed or on reliability. The disks work silently enough and are not heated strongly. But certainly Atlas 10k needs to be extra cooled. The proposed maximum operating temperature is 50-55 degrees. It is pleased that the figures indicated in the description are well matched with measurements (especially Sustained Throughput). Tested Atlas 10k also was distinguished by absence of defects on a surface (Adaptec SCSI Explorer 32 was tested), though it is just alternative implementation of distribution the defect list instruction. Despite of existent technology S.M.A.R.T., each manufacturer invents its own solution. For Quantum it is Data Protection System (DPS) which together with Quantum Shock Protection System and temperature control increase common reliability of systems.

Seagate

The company Seagate has a little bit more range of models. However it is possible to note that for example the model Barracuda 36 is similar by parameters to the series Barracuda 18LP and as a matter of fact is 36.4 GBytes version of this set. Traditionally disks with RPM 7200 are released under the brand Barracuda and faster ones under the brand Cheetah. Unfortunately it was not possible to find out what features of SCSI-3 are really used in implementation Ultra160 disks interface. Seagate does not give these data. But the latest model - Cheetah X15 with RPM 15000 has pleased us with its speed, it is the really first disk for which interface UltraWide SCSI is already not enough. Read rate at the beginning of the disk really reaches 41.3 MBytes/sec! Seagate very attentively concerns not only to high-speed parameters of the disks but also to reliability. Having conducted mass probing the company has developed even special container for packing disks which appreciably reduced the number of faults connected with incorrect transportation.

Seagate Cheetah X15

As Cheetah X15 undoubtedly is the remarkable product and we shall tell about it in detail.

At first some descriptor data:

  • RPM: 15000
  • Seek Time Average: 3.9 ms
  • Sustained Throughput: 38.0-47.4 MBytes/sec
  • Buffer Size: 4 MBytes
  • Interface: Ultra160

And photos:

As you remember Seagate was the first to present the disk with 10000 RPM. Then the first generation Cheetah was in comparison with remaining disks not only faster but also noisier and besides the first forced cooling was required for. Today Cheetah X15 does not differ much from 10000 RPM disks by the last two parameters. By noise it is quite comparable with Cheetax 18XL and Ultrastar 36LZX. And as for temperature all disks at the tests were cooled by one 80mm ventilator with the large rotation rate. In these conditions on Cheetah X15 it was possible to note small heating of tank and the rest of disks were just of room temperature.

Now about measurement technique and problems connected with it. Firstly as this disk's read rate from the first tracks exceeds 40 MBytes/sec, this disk was measured already on Ultra2 the controller. Actually UW tail with active terminator was changed on Ultra2 tail and the appropriate terminator.

Secondly the test Winbench 99 represented at the end of 1998 does not cope any more with the task - the results of some tests are obviously erratic - even if to consider that the data is taken from disk cache, it is impossible to reach 68 MBytes/sec by 40 MBytes/sec bus. Hang-up of the program also was marked at the attempt to measure percent of processor loading during the tests for Windows NT. As for results for one part (Access Time, Transfer Rate, CPU Utilisation) the spread in several measurements of one disk did not exceed 2%, therefore these tests repeated only 3-5 times. But the results Business and High-End Disk WinMark 99 could differ in 3-7%! For reliability these two tests were conducted 10-12 times and the average was sampled. Most likely there is unambiguous dependence the results of these tests from the first ones but the process of measurement gives the random corrections connected with the large speeds and insufficient period of measurement, so that while we should take the obtained results carefully.

At choice UltraWide or Ultra2 interface having compared for example Seagate Cheetah 18XL and IBM Ultrastar 36LZX in these modes we have got a difference in results no more than 2%, so that it is possible to say that in our case the choice of UW SCSI has not resulted to significant losses of productivity. For Cheetah X15 the difference was already more appreciable, the losses for UW in Business and High-End Disk WinMark 99 were 4.2% and 7.6% accordingly to say nothing about the decrease of transfer in the beginning of the disk from 41 up to 35 MBytes/sec. It is all correctly only for the case of one disk on the channel. The advantages Ultra2 in RAID systems are unconditionally higher. But the replacement of the processor for the faster one (P3-600E) will for certain be reflected in results of all disks - for example for Cheetax X15 increase has made 8.2% and 7.9% in the tests Business and High-End Disk WinMark 99.

Well and at last results of the tests in the configuration similar (except interface - here Ultra2) remaining disks for matching: Cheetah X15 (ST318451LW).

IBM

IBM set of SCSI disks is released under the brand Ultrastar. Except the set the hard disks IBM have also a four-letter title of model. Under Ultra160 we understand the implementation only of three items SCSI-3 but under Ultra160 + of all five ones As well as each large manufacturer IBM offers also unique technologies reliability of systems operating its disks. In particular "Drive-TIP" serves for the temperature control but " Predictive Failure Analysis " as it is clear from the title notifies the users about potential problems in disk system.

Nowadays IBM offered disks:

Fujitsu

Having presented in November,1998 series MAE and MAG Fujitsu a year later refreshed its bar of SCSI. Usage of the fifth generation GMR heads and increase bit density up to 9.1 GBytes on the disk has allowed to increase productivity on 30%. For new models interface Ultra160 (160 MBytes/s data transfers, domain validation and CRC) is used. Unfortunately SCSI production Fujitsu is aimed mainly to the corporate American market and in another areas the new models have not appeared yet.
