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.

    Only 120GB, 160GB and 500GB sizes available? Hopefully the rest follow shortly.. I'd like to get two of the 300 or 400GB drives. Reply

    I'm intrigued by the idea of SAS, but I'd really like to see a PCI-E SAS controller. Any idea when such a beast might appear? Reply

    Why would you need a standard SATA controller unless you are running a large RAID array? I don't even think there any motherboards out there that have PCI-E and lack SATA. Reply

    He asked about SAS, not SATA. Almost 0% of systems come with a built in SAS controller which is why he would want a PCI-E device.

    SAS could turn out to be very nice for gamers or people who want high performance.

    Right now Raptor is pretty much the only high performance choice. SCSI drives are faster but (besides the price) have complications of needing a controller, termination, and other config issues that can make them a real pain.

    SAS has the potential to let you just drop in a 15k drive no muss no fuss, and the controller still supports all SATA drives.

    So the ideal configuration for a high perf machine might be:
    1 SAS Controller
    1 Small 36 or 72GB 15k drive (blows away a raptor)
    1 300-500 SATA drive for storage

    Much faster than a raptor system, easy to install and configure, and only $200-300 more in price (not huge for an enthusiast system).

    Windows boots and game levels load *very* fast on a 15k drive.

    Ahh, my mistake.

    Regarding the 15k SCSI drive for Windows XP, it's deffinitely NOT faster for general use. I have a 73GB 15k Fujitsu in my workstation at work. With bootup and general tasks it is SLOWER than the Raptor I have at home. It would be a waste of money for a home user, especially since SAS is currently A LOT slower than standard SCSI drives. 15k drives are only useful when you have many concurrent I/O's, which homes users will not have unless they are running a file server for their whole neighborhood over a Gb backbone.

    HP is trying to sell SAS on the new Proliants but I don't know anybody who has purchased them yet to get an idea of the pros/cons of using SAS in the real world. But again, since SAS is currently slower, why spend more for less?

    That's interesting to hear. I'd been told before that SCSI drives tend to be more optimized in the firmware for server tasks than for workstations, but despite that I didn't really think that a 15kRPM SCSI drive would "feel" slower than a 10kRPM SATA. Although, I'm not sure that I see where you're getting the idea that SAS will be that much slower than SCSI; I'd like to see some proof (either logical or benchmark) of that.

    Largely, I was contemplating SCSI or SAS because I thought it would bring at least a slightly noticeable improvement in "snap" over my 1st-gen Raptor. I obviously don't posses the budget for a solid state drive right now, and without doing some insane RAID setup (which wouldn't help for access time, which is what I need anyway), I don't see how there's much room for improvement of the hard disk bottleneck in my current system. For what it's worth, I have 2GB of RAM and don't find that limiting, so going to 4GB probably wouldn't help (loading Photoshop the _second_ time is plenty fast enough, so I'm convinced that my Raptor is holding me back).

    What's the failure rate of a 15K drive? and at 36GB, thats not gonna cut the mustard for my game drive. Right now, I'm at 42 gigs on just my games partition. True, about 15gb of that is Steam, but still, it takes 20+ gigs for Steam, Morrowind, KotOR, Galaxies, and Doom3 alone. I don't think even the 72 gig 15K drive would satisfy my needs, and I've never considered myself a massive gamer, games are just getting bigger. Reply

    Wow, I didn't even realize Silent Hill 3 was 5 gigs?! But seriously, SATA is the way to go. There are so many limitations to IDE that it's a little rediculous. Raid is easier on sata, you dont have to worry about the whole master-slave relationship (my pet peve of pata) and the cables are already rounded! (ok, that was a cheap one) Reply

    Is there really any benefit to going SATA?

    I'd say that if you are comfortable enough with PATA, pick one up at your local BB or CC. I recently picked up a seagate 160 GB hard drive for 20 dollars.

    But when's the expected delivery date of your mail-in rebates? Oct 2009? Reply
