  1. 6,12TB on the 160GB Intel X25-M G2 with 18 reallocated sectors in my desktop. Will post info from a few more SSDs around here when if i can extract any meaningful numbers. Do you know any way to get write-info from MTRON SLC drives or OCZ Revo drives? (I can 'guesstimate' but it would be nice to be precise). Morten

    Spare area / redundancy

    I was more worried that the different models didn't have the same features. My main reason for buying Intel is reliability (when we bought our first SSDs in 2007, we bought 40 MTRON SLC SSDs, more than 30 have failed since then. We have had a failure rate less than 5% on nearly 100 Intel X25-E drives). The Intel SSD 320 should survive a single failing NAND die, but I was wondering if the lower spare area percentage on the smaller drives meant that this feature wasn't enabled on the smaller drives, thus giveing then lower reliability.
  3. One thing that bothers me a bit: It seems that the smaller drives has a lower spare area percentage than the 300GB drive. 120GB: Physical 120GB, user capacity 111GB, spare ares 9GB which is 7.5% 160GB: Physical 160GB, user capacity 149GB, spare area 11GB which is 6.9% 300GB: Physical 320GB, user capacity 279GB, spare area 41GB which is 12.8% 600GB: Phycical 640GB, user capacity 558GB, spare area 82GB which is 12.8% The user capacity numbers are from anandtechs review. Does this mean that the smaller drives does not have the same RAID4-like redundancy as the 300GB drive? Or am I wrong about the physival sizes of the smaller drives?
