Bought two of those for raid 0, well one of them worked for 1 day only. Now i have to replace it with WD (a bit of a pain)

Drives where delivered in a bag instead of box for maximum protection as stated on western digital website

Great Buy

I'm not going to bother going into any details. Because put simply this is an awesome HDD and does exactly what it says on the box. Bought this back in May and has been so far very reliable and stable.

Why 4 stars? It's not the quietest HDD around. It really doesn't bother me at all though, it's not some really annoying loud sound or anything, but it is quite audible. May be a problem for those of you who are picky about that.

Other than that this is a great buy and you won't be disappointed (especially not for

Brought two for use in raid 0. Been working OK for well over 6 months now. Great buy.

Excellent product

This is a good hdd although sometimes it can be a bit noisy. Not too much though which still allows me to rate this a 4 star. Go for it!

very fast HDD

Coming from a 250GB HDD with 8MB Cache XP Windows, to this HDD and Windows 7 there is a huge difference in speed, web pages come up instantly where as before i could wait up to 15, 20 seconds. I very happy with this and the fact its 640GB. How much faster are the SSD ?????. Personally i think there to small space capacity and over priced, this is well worth the money.Also ordered this wednesday afternoon came thursday morning excellent service thanks overclockers.
