erm...Bulanula... write endurance in this thread alone has been proving you wrong, the 25nm drive has been having fairly substantially higher writes per MWI percentage ( 34nm- 90.49TB @ 50%, 25nm- 97TB)
and looking at intel spec sheets (I still havn't seen an official review on a 320 series 40GB drive),
Writes- ~28% faster (45mb/s vs 35mb/s)
reads- ~17% faster (200mb/s vs 170mb/s)
4k IOPS read- ~20% faster ( 30k vs 25k IOPS)
4k IOPS write- ~48% faster ( 3700 IOPS vs 2500 IOPS)
on what is essentially the same controller
