  1. There is no mention of which controller they used. I suppose it must have been a Marvell 88SX6041/88SX6081 or Silicon Image 3124, both PCI-X, since these are the only ones I have seen that currently support NCQ.
  2. Yes you can have Win98 and WinXP use the same swapfile on a partition, but I think it has to be a FAT partition otherwise Win 98 will not be able to use it. You will have to rename WIN386.SWP to pagefile.sys in Win 98's system.ini file. More detailed instructions can be found here

    Sata Bridge Chips

    I think all the bridge chips fitted by manufacturers to hard disks to enable "bridged SATA" are Marvell 88i8030. Silicon Image also make bridge chips such as the Sil 3611 however, which are used on adapters including the Abit Serillel 2 adapters and also in some enclosures. Sil 3611 Satalink Device Bridge
  4. The Marvell 88i8030 mentioned by nikitusha is a bridge chip so only supports ATA command queuing. The Marvell 88SX60xx series (88SX6041 and 88SX6081) that I mentioned in a previous post are Serial ATA II Host Controllers and feature "Support for both Serial ATA II Native Command Queuing and Serial ATA I/ATA-6 Tag Command Queuing". These are also PCI-X the same as the Silicon Image 3124. This means there are no PCI versions I have seen that support NCQ. I suppose this means that mainstream users may have to wait until PCI Express or Intel ICH-6 and other brands of newer Southbridge chips before they are able to use NCQ. When the Seagate 7200.7 series was introduced I read that these disks would support NCQ. I have now seen posts by people suggesting that only the new 200GB ST3200822AS version will support NCQ. If this is true then I wonder if a firmware update will be necessary to enable NCQ on 7200.7 models released prior to the 200gb model or if the earlier models will not support NCQ. I know that all of the 2.5" Fujitsu MHT-BH models support NCQ for notebook users, but they are only 5400rpm and will not be available for a few months.
  5. Very high figures for Business Disk Winmark 99 occur on all Seagate SATA drives running on a Silicon Image controller with any driver that includes the Windows Accelerator Driver. This optimises performance for small file file sizes and in effect tweaks the results for this test. The result of this is the figure is proportional to the size of the disk cache, because the data is streaming directly from the cache. This was reported by Lost Circuits on page 7 of their review of the Seagate Barracuda V in February 2003 where the result is 38,300. My own result for Business Disk WinMark 99 with a Barracuda V in March 2003 was 35,400, (High-End was 39,200). Both these results were on FAT 32, results may be a bit less using NTFS.
  6. Yes in that demo they used a Sil 3112 based controller, which Silicon Image thay said they had made with enhanced capabilities to enable it to support Native Command Queuing, yet they do not mention this ability in their product documentation today, only for their later chips. Also the current Seagate 7200.7 drives are also supposed to support Native Command Queuing. So I wonder why the delay in NCQ being available to users? Must be still waiting for Intel to optimise the software needed. It will be interesting to see if the performance of NCQ when it is available to end users matches that shown by the prototypes tested.
  7. I don't know how much difference NCQ will make. Seagate and Fujitsu of course claim it to be a great advantage but you would expect them to say that seeing as they are the only ones who offer it at the moment. I suppose it is only a standard and how well it is implemented is up to the manufacturers. It is possible for manufacturers to optimise the firmware in their drives to suit different kinds of usage, so NCQ may be the same. We will possibly see nice charts from the manufacturers showing the increase in I/O and perhaps other benchmark results used in extolling the superiority of NCQ drives. However how this translates to "real world" performance for different kinds of users will probably have to to wait until we see some comprehensive testing that will give us more useful results, like a review from Storage Review!
  8. The TCQ that SCSI uses is different to the TCQ used in ATA or SATA 1. ATA or SATA 1 TCQ I suppose is the same as the "tag 'n seek" used in IBM ATA drives. SATA 2 NCQ is different again. I know very little about this but I think the differences relate mainly to whether it is done in hardware or software and the number of commands that can be queued and reordered. For NCQ this is 32. I assume it is less for ATA or SATA 1 TCQ. I am certain that the number is much higher for SCSI TCQ. Perhaps an SCSI expert will be able to enlighten us about this. I don't know the performance implications of any of this, but I assume the greater number of commands that can be queued would increase the I/O performance in server type use. Whether this would be of very much use for many desktop single-users is probably debatable.
  9. The 74GB Raptor is a bridged SATA drive and supports TCQ (Tagged Command Queuing). The Seagate 7200.7 is a "native" SATA drive and supports NCQ (Native Command Queuing). TCQ and NCQ are different. The only other drive I know of that supports NCQ is the recently announced 2.5" Fujitsu MHT-BH. It uses the Marvell 88i6535 SOC (system on chip) to enable native SATA.

    Ad And Spyware

    For some people, perhaps those with children, prevention may be better than cure. SpywareBlaster (donationware) is good to prevent spyware fom ever being installed in the first place. SpywareBlaster
  11. I think the Silicon Image 3512 chip also supports Native Command Queuing but I've only seen it integrated on Shuttle and Gigabyte Athlon 64 motherboards. The Marvell 88SX6041/88SX6081 chips also support Native Command Queuing but the website says they only come in PCI-X form. Marvell 88SX60xx Serial ATA II Host Controllers
  12. "As has been the case with all bridged solutions (that is to say, all serial ATA drives except Seagate's Barracuda series), the new Raptor features both a newer 15-pin power connector as well as the more traditional 4-pin molex receptacle." That's strange, I thought the Samsung Serial ATA drives have a bridge chip and only a 15 pin power connector and no molex. I'm sure I saw a photo of a Samsung Serial ATA drive in a review somewhere and it had no molex connector. Anyway that's only a minor matter, I enjoyed reading the preview. These new Raptors are the ant's pants now that they've got rid of the whine. The larger capacity should make them appeal to many more people who would like super speed and a five year warranty. If they become a popular choice, it may convince other manufacturers to speed up the development of their 10,000 rpm (or 15,000 rpm ) Serial ATA drives, which will be good.
  13. As I mentioned I haven't read that magazine test but have only seen the extract I posted. However there are many reviews of these Samsung drives in both PATA and SATA forms and all of them commented favourably on the low noise: modthebox digit-life.com/sata-summer-2003 digit-life.com/samsung-80gpp ixbt-labs.com/pata-8mb/ Details of NoiseGuard, SilentSeek, and ImpacGuard in this review: mbreview.com/sp1614n
  14. I don't know about the US, just letting you know they do exist. If they are available now here in Australia, is it reasonable to assume they will be available in the US soon? I don't know. A recent Australian computer magazine has these SP model Samsungs as their hard disk shootout champions. I do not subscribe to the magazine, so I do not know which other hard disks they tested or the way they test, but I thought you may be interested. It would be good if Storage Review could get some from Samsung to test. Labs Winner Nov 2003 PC Authority "The Samsung SP1614N is our Labs Winner - and by a big margin too. It scored strongly in both benchmarks to yield pole position in performance, and following our current labs-trend, it outperformed its SATA counterpart (only just)."
  15. The Samsung SP0812C, SP1213C and SP1614C became available during the last week in Australia. They are for sale at PC's On A Budget and Microtrade and possibly others. Hopefully they will be available in your country soon as well.
