Re:Why doesn't every company buy developers the best hardware? by jrockway on Tuesday July 19, 2011 @09:39PM (#2783930)
Pretty sure this is not the case for Linux. LVM supports discard, so md probably does as well.

Also, you don't immediately need a replacement drive: RAID1 boots fine with only one device. Assuming your company policy is to have RAID1'd SSDs for all developers, you're probably going to have extras on the shelf anyway.

Time machine is for accidental data loss. RAID is for disk failures.
