SATA - 3.0Gbps

SATA drives in the 3.0Gbps category have gone up about $0.02/GB since our last analysis two weeks ago. It seems as though the 250GB hard drives are still the “best bang for the buck” at the moment with the 250GB Hitachi Deskstar [RTPE: T7K250] leading the competition at $0.44 per GB. Coming in close behind is the Western Digital 250GB Caviar SE [RTPE: WD2500KS] at $0.45 per GB. The prices on most drives are also trending down at a steady rate, with the WD drive dropping about $1 per week.

Those interested in the fastest access times will benefit from the 10,000 RPM of the WD Raptor. The Raptors often fluctuate quite a bit in price, with an overall slow drop as time passes. Although they are not much cheaper than our last analysis, at least one vendor still has a $20 mail-in rebate. The best price that we can find this week is for $166 shipped, or $152 if you're willing to wait for the MIR.


Western Digital 1.5Gbps 74GB 10000RPM 8MB Raptor

The new Seagate 7200.9 SATA drives have only been available for a week (and many models are still on pre-order), but a few are already starting to come down in price. We noticed that the 500GB Seagate Barracuda [RTPE: ST3500641AS] has dropped over $20 in just one week, and clearly, prices have not yet stabilized. Currently at $0.75 per GB or $377 total, the drive is very expensive, but there really isn't a lot of competition in the half TB market yet. If size matters to you, be prepared to shell out more money, similar to the 10K RPM "tax" on the WD Raptor. Worth noting is that the 500GB model does have a 16MB cache, so performance should be better than most other SATA drives. The cheapest 7200.9 SATA drive that our RTPE is showing is the Seagate 160GB Barracuda [RTPE: ST3160812AS] at $0.58 per GB, which is quite a bit higher than competing drives. We’ll be sure to keep an eye out on the 7200.9 drives for the next coming weeks and see how they fair.

    Smaller cables, and on many chipsets slightly faster performance. Overall, it's not enough that I'd really upgrade to SATA (i.e. get rid of a PATA drive for an SATA). However, I'd purchase SATA if buying new, unless there was an awesome deal on a PATA drive. Many intel motherboards, for example, only come with one PATA connection, so you'd max out at a DVDR and a single HDD.

    another reason I am hesitant to go with SATA with a new build is that you need a floppy drive to install the SATA drivers.

    I've heard of using USB keys or CDs to install the drivers. Anyone have a link on how to do this?

    Whenever I recommend new systems to people, I always suggest PATA, because its cheaper and they don't have to worry about obtaining a floppy drive in the future if they ever have to reformat.

    While the cables are nice and thin, ive also heard of cables falling out, because the attachment system isn't very secure.

    I didn't need any SATA drivers to install Windows XP SP2 on my SATA drive connected to an nForce4 SATA channel. The box doesn't even have a floppy drive.

    oh. somehow i was under the impression that all SATA controllers required drivers from a floppy.

    btw, I've already gotten my rebates. i purchased the drive sometime in early september.

    Both of my computers run SATA with no floppy drives. Whether or not you need a floppy to install drivers depends on the the SATA controller.

    Most motherboards do not need a special driver for SATA.

    There is no reason not to use it in a new system. Less cable mass, simpler configuration, etc.

    I've been under the impression that it's best not to run an optical drive and a hard disk on the same IDE channel, as well. Maybe it isn't the case with newer optical drives, but if true, it's definitely another reason to prefer SATA drives on a mainboard with only one IDE connection.
