Dollar for life wise the cheaper ones may not make sense, but ZFS would help detect and mask failures.

The 'I' in RAID can stand for "inexpensive". It can make sense to mirror two cheap drives on non-big data server applications. So the HD form factor for solid state storage is a good thing in this case. Two 60GB SATAIII drives for $45/ea is really cheap. $60 for 120GB. Wow.

Is there any point trying to do RAID with these, and can that even be done?
