Would it be OK to use a SATA 6Gb/s desktop drive in a server?
Say for example a 4 Seagate ST31000524AS drives in a raid 10 array.

I will be using NexentaCE.
I will be using a 240Gb SSD as a L2ARC cache (read) to the RAID array.
I will be using a smalled SSD as a ZIL for the write cache.

I cannot find any 1TB Constellation drives for reasonable prices anymore.
