I'm looking to buy 2 Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard drives and use Raid 0.

I have heard that the caviar black does not do well in raid 0. Can someone confirm this for me? If so what other hard drive with specs of 64mb cache and SATA 6.0Gb/s would you suggest? Or even what would you suggest as a raid with equal performance? I’m looking to spend under $100 a piece. So was interested in the caviar's until I heard that comment.

A minor point which does not answer your question. At this point SATA3 (6 Gb/Sec) is irrelevant for HDDs because no HDD can transfer at that speed. Only a few SSDs can. And you can connect an SATA2 HDD to an SATA3 port and get full SATA2 speeds (or whatever the HDD can manage). So SATA3 ability on the HDD is a null issue for now.

Where did you hear that the Caviar Blacks don't do well in RAID0?

Finally, the Obligatory Warning: RAID0 will lose all of your data if either drive goes bad, or if the controller goes bad. Keep backups if you user RAID0.

(I sure had a lot to say for someone who couldn't answer your question.)
