    Re: Drive Alternatives to Raptor

    I have an older version of this drive:

    http://www.newegg.com/Product/Produc...82E16822145082

    Actually I have two, and I'm using them in Raid 0. For less than the price of one of the regular raptor 150's (not the X version) you can buy 4 of these drives and use them is a Raid 0+1 array. My 2x80GB Hitachi's give me reads in the area of 97mb/s on the nVidia controller for my board. They have some 160GB drives for $70 (x 4 = $280. Close to the price of a Raptor 150.)

    There is also this drive:

    http://www.newegg.com/Product/Produc...82E16822144424

    It's a WD 400GB Raid edition drive. It sells for $182, but I think intelliboy in the trades forum had one for around $165 (he's had it a while, so he might deal - it's brand new). This drive features some of the same specs as the raptors, but it doesn't have the same RPM's.

    Or anywhere near the performance of raptors, especially the new 150 gig model. Raptor access time in particular is much much better.

    it probably shares no parts at all with the raptor. the raptor's platter is smaller and thicker, and the drive arm is much heavier duty to facilitate the short access times.

    they might share things like a memory chip or controller of similar design, but that's about it.

    also, when you raid lots of drives, access times suffer.

    Re: Drive Alternatives to Raptor

    I know that the performance mostly comes from the rotation speed. By the same features I was referring to this:

    NewEgg lists both the 400GB drive and the Raptor having those features. That's all I was referring to being the same...

    Re: Drive Alternatives to Raptor

    i see.

    btw, the raptor's performance is probably more due to the better seek arm/motor and the smaller platter. the higher speed is icing on the cake, but probably doesn't help as much as you think it does.

    stephen is correct. The 10k spindle speed acounnts for only 1.2 ms of the 5-6 ms access time improvement relative to 7200 rpm models.
