    Fastest way to push data?

    You have a dual processor dell. You obviously don't have an inexpensive machine or a particularly restrained budget. I suggest you go all out. Get 2 15000k rpm drivers and run them in RAID 0 on a good SCSI RAID controller. Maybe even a third for photoshop and windows to scratch over. Not cheap, and you need to keep backups, but you should be scaling your hard drive speed at the same rate as the rest of the system, not leaving it strangled by a commodity 7200rpm drive.
  2. The 3112 chip, and its bigger brother 3114, is used on many motherboards for SATA support. It is a fast and inexpensive solution that works in both windows and linux. (You may need a driver disk to install windows though) I would say it is better then the promise and highpoint cards, who are pretty much known for their problematic performance (at least with the older ATA cards).

    sygate firewall taking 2/3 bandwidth away

    It is a protocol you must install. Click the Install ... button, select protocol and then select the one with IPX/SPX on it. Do this for both computers and disable the TCP/IP option. (if you want to try bypassing all this internet software/firewall crap)
  4. An SATA card based on a Silicon Image chipset is likely to be the best supported under Linux and XP. Both have drivers that just work

    sygate firewall taking 2/3 bandwidth away

    Yep, user space firewalls add a large overhead to the TCP/IP stack, with the inspection of each packet probably requires that the packet is copied from the TCP/IP stack to the firewall program, inspected and then put back. Such memory copying and the context switches associtated with a user space firewall mean that throughput will be poor in any case. It is fine for low speed internet connections, not good for LAN transfers. You should completely remove sygate and install smoothwall on an old box to handle internet firewalling if NAT is not enough protection for you. Another possibility is that you turn off TCP/IP on the intel cards, and use something like IPX/SPX instead. That way, sybase won't inspect the packets because they will never touch the TCP/IP stack. Not sure how quick it will be though, because there is probably no IPX acceleration in the intel drivers.

    Fast IDE drive, size doesn't matter

    I second this recommendation, but with my own spin. The Hitachi's mechanics are also somewhat faster then the competition, which really does improve performance. My 7K250 160gig drive was fast when I was using it as a boot drive. (I now have a raptor as a boot drive, since I am a sucker for fast/affordable hard drives)

    Spin down when not in use

    Don't forget that the PSU is not 100% efficient. If it's 50% efficient (not sure on real-world amounts), you can double those figures. The main thing for me is to have the system run quieter & cooler whilst drives are spun down. cheers, Martin 199318[/snapback] Actually, the raptors are really NOT designed to handle repeated spin down/up cycles. They are rated at only 20000 stop/starts as opposed to desktop drives which are ussually rated at 40000-50000 stop/starts. Laptop drives are much more rugged in this respect, ussually rated for 100000-200000 stop starts. That indicates that the raptors head/parking design wasn't built for constant shutdown/startup.
  8. Ok. my main concern was the first one, that things would be slower through an addon controller in a PCI slot. Regarding choosing the biggest drive - i just meant that each drive mentioned was the largest 2 platter drive (I just have this thing against 3 or more platter drives..lots of bad luck over the years w/ them). the extra 50gb certainly would be nice, but that wasn't my determining factor. 199277[/snapback] Use which ever drive you want. Or better yet, use whatever drive is easiest, which is probably the PATA drive because you don't need to do fancy crap to install windows on the PATA drive. The performance difference between a SATA 7200.8 and a PATA 7200.7 will not be particualarly great.
  9. Yes there is .... unplug the PATA drives, and install windows on the SATA drive. The SATA drive will become C. Then plug in your PATA drives, start windows on the SATA drive and use disk manager to set the PATA drive to D! Edit: after you install windows, go into the CMOS setup and MAKE SURE that the SATA drive is booted first by the BIOS, otherwise it will boot the PATA drive and won't use the correct windows install.

    Terabyte desktop drives

    Problem is that there is virtually no market pressure for larger drives. And, even scarier is that there is even less market pressure for faster drives. OEMs just seem to want slow, cheap drives that they can stuff for minimal cost into their slow, ugly machines.

    SCSI HDD diagnostics

    Of course, you could exersize the drive to death for however long it takes, and then claim that there was a latent failure waiting to happen. You could do that with ANY drive though, new or old. I think a short run for an hour or so will be suffiencent to determine if a drive really has had a head crash that caused head damage, or if the heads are still in good working shape. Of course, the drive may still fail after a few months, but all drives have a chance of failing, new, old, recovered or not.

    Daveseeton: Use broadband instead of dialup.
  13. Sheeze: Its really, really simple. 1) Set BIOS to boot SATA drives first 2) Disconnect other drives. 3) Install XP 4) Reconnect other drives.
  14. Make sure the BIOS boots from the SATA first then in the CMOS setup

    Question for PSU experts

    Newer motherboards power their processors from the 12V lines rather then the 5V and 3.3V lines. Using 12V lines to power the processor means that the PSU can transmit more power to the motherboard over fewer wires. This means that newer PSUs focus on supplying more 12V rather then 5V/3.3V
  16. I think there is simply a big hole in the SR desktop drivemarks. The I/O trace was recorded in a certain order, and is played back in the same fixed order. The whole point of TCQ/NCQ is to allow the drive to reorder I/O's so that some threads/processes can run faster than they otherwise would. The SR DeskTop Drivemark adds delays after any I/O reordering, so of course it comes out slower!!!! See further details here. This is also why SCSI drives don't reach there full potential in these tests, despite people's real-world reports of better performance. cheers, Martin 198480[/snapback] I can see that being true. While I would love to have SCSI, the price is simply too high for the benefit. The raptor is good because it brings performance at an easy to aquire price point. Prices have dropped so far that getting a raptor today is cheaper then getting a midrange hard drive was 5 years ago.
  17. FAQ Entry on WIndows issues with SCSI and cures for the problems! As for performance comparison, check out the "performance database" here at SR (Raptor vs. 15K MAU) and compare your favourite 15K and the raptor. This will give you the cold hard facts. PS. We are friendly enough here, that we don't believe in charging for advise! PPS. Exactly what application do you want the drive for? 198413[/snapback] a fairer comparison is TCQ is bad for desktop duties, and blunts the raptor considerably.

    Best bet for 250g HDD

    It doesn't seem like the newer hitachi drives make that noise anymore .... I have certainly not heard it from my drive.
  19. Errr, I cannot believe that 14 hard drives would not cause a significant effect on the heat level in a case. Each hard drive will always be consuming about 8 watts on idle. Thats 8 watts for each hard drive. Thats a total of 112W of power constantly being used, and a total of 112W of heat being dissipated. While that 112W is being spread over much more air, it still would increase case temps a lot, making the cooling of the processor much harder. On top of the hard drives themselfs, the PSU would probably be expending about 30-50W of heat to supply the power for the hard drives. Try disconnecting most of the hard drives and see what effect that has on CPU cooling.

    Raidcore Problems

    Right .... As if the engineers who designed molex connectors 20 years ago were any better! And the sad part is that we still use these bastard connectors, and they still break, get stuck, hurt people.
  21. See:;308421&sd=tech Apparently, you have to log into safe mode to get the security tab on XP home. From there, you can claim ownership of the files/directories and reset their permissions.

    Clear Windows

    It would certainly be a good idea for hard drive makers to do. Put a BIG window on the top of their high end drives and sell it for an extra $50. I am sure there is a reasonable market for this. Of course, the question is, just how big a market is it? Hard drives are run with razor thin profits and MASSIVE economies of scale. Unless a lot of people are willing to buy the pre-modded drives at a significant price premium, it may simply be not profitable enough for the drive makers to pursue.

    WD3200JB at Tom's

    Only way to protect your data is to do proper backups. Nothing else will come close. Any drive you buy, from any manufacturer, is more likely to die from some random factor that you cannot predict beforehand, rather then from the actual design of the drive itself. Unless you are buying 100's of drives, your experiences will have nothing to do with the design reliability. Only a few drives models end up with systematic design or implementation problems, eg the IBM 75GXP.

    Did I really have bad sectors?

    Yep, thats typical of a serious head crash. You lose a whole pile of sectors, and your drive heads become damaged. Soon afterwards, more and more bad sectors develop as the damaged heads and loose magnetic particals spread chaos over the drive. Eventually (in a few days or so) the hard drive becomes useless. If you are lucky, a head crash will not cause major damage to the heads, and you will be able to use the drive for some time without further problems.

    Failed Hard Drives

    Yep, rare earth magnets are definitely worth retreiving from a hard drive. The rare earth magnets in hard drives have an amazingly high magnetic strength. Don't put one on the fridge if you ever want to get it off (easily that is)
