I have two 80Gb SATA hard drives set in a RAID array and now ned to ugrade to perhaps two 500Gb hard drives. The current drives available are now listed as 'SATA-2'.

What is the difference between SATA and SATA-2?

Can I safely upgrade to the SATA-2, will they be compatible with my Gigabite GA-8KNXP?

TIA, Peter.

They should be backward compatible. SATA2 will run at SATA1.

SATA1 is 150MB/sec. SATA2 is 300MB/sec. If not mistaken :D
In practice they probably won't be twice as fast :D

Yup 150 and 300MB.

Just make sure you jumper them to SATA 150, or else they'll never work.

As some SATA 2's maybe set to SATA 2 by default

When buying harddrives the important things to look for is : Connection, Revolutions per minute (the higher the better), Memory Cache( the higher the better).
