Default Hard drives in RAID

Guys just looking at getting some new drives. Currently have WD 250GB SATA 2 drives 4 of them RAIDed in RAID 0.

Looking at reducing the number of drives and more storage. Deciding between to go for either 2 x 640GB or 2 x 1TB drives. Whichever is the bang for the buck and will RAID better. Seagate or WD.

Thanks

Well the 640s are about half the price of the 1000 so I would go for those. I doubt you would see much RAID performance difference but the 640s also have a really good rep for speed.

It really shoulsdnt mater what brand you get for RAID, oh, cept for the actual seek times. Remember that you are reading and writing to multiple disks at once. The more the disks, the faster the performance. I would look at sustained throughput, cache size and seek times. Just make them all the same, or very similiar.
