I knew you were not testing it, but I didn't know you had two SF2281s in one rig. I think idling is the opposite extreme of the endurance test anyway for SF2. On my system, I've been writing about .7 to 1.2 GB a day on the system drive. I was using my Intel X25-E, but cloned that to my Vertex Turbo 128.

Incidentally, I've been wondering about SF 1 and 2. Since they don't have DRAM caches, they use nand on the drive. Maybe SFs aren't limited by the NAND endurance overall, but perhaps they keep wearing out the same NAND device from storing all the associated SF data. If it didn't adequately rotate where it stored all the data necessary to make SF work, maybe writing millions of files is more detrimental than just writes to NAND.
