74GB Raptors in RAID 0

[nick112]

Hi, I was thinking of getting two of these - Western Digital Raptor 74GB 10,000RPM SATA 16MB Cache and putting them in RAID 0.

Does anyone know what speed increase I should expect from these?

Is the 150GB versions any faster than the 74GB versions?

Thanks for any advise.

Compared to what?


If comparing the 16mb cache versions then not really. They might not perform exactly the same in every benchmark but should have similar performance overall.

Just to a normal 7200RPM drive.

IMO a single 150GB would be faster than 2x74GB.

Saying that I wouldnt use raptors as they are sinularly as fast as 7200rpm discs in RAID 0 or there abouts and dont get any beneficial performance boosts in raid configs as far as I have seen

So basically I'm better off just getting a single 150GB Raptor and not bother with the whole RAID chestnut.

Thanks for the advise guys, I'll prob get this on monday (pay day ) with whatever TFT I end up choosing.

Hmm those Seagate's do look pretty nice and the RAIDing seems a bit better as well.

ATM I'm thinking of getting a 150GB Raptor (for windows, apps etc) and 320GB Seagate 7200.10 (storage).

I could always put in another Raptor at a later date if I fancied a speed increase.

Theres a pretty nice review of the Seagate over at AnandTech: click.

Thanks for all the info.
