well thanks for clearing that up for me LeJimster, i was considering buying a transcend 128GB sata 2 SLC SSD for my pirmary boot drive but the read/write rates were abysmal (150mb sec read 110mb sec write if memory serves correct), i was questioning why the prices ranged to rougly £200 more than an equivical mlc drive, now that i know why i don't think that, tbh, the slight performance increase warrants the vast increase in cost. And to be honest, if a standard mlc has a 2 million hour mtbf thats not really going to affect longevity too much since most of us will have moved on long before then (specifically when 128GB drives become more cost/performance effective) unless this is a one in a time upgrade for enthusiasts which i can't really see being the case.
I would have expected crucial to have performed much, much better though in comparison to other memory vendors like OCZ and G.skill (which does dissapoint me a bit as they have great products available in the Memory arena) and it is suprising really when i think about it that intel are currently producing the best MLC/SLC drives on the face of the planet (although they are also extremely expensive, i would have expected intel to be under dogs though in this area tbh), the best guess that i have is that Crucial are/were trying to capitalise on the budget scene but left it a little too late in the game for their drives to be considered a proper alternative to drives like the OCZ Apex/Vertex or samsgun which proves even more, imo, that samsung still produce the best performance/gigabyte/cost effective SSD drive even up to 128GB capacities (where their only other real competitor is the OCZ Solid Series and G.Skill Titan at which point prices start going mad again), which leaves me to ask one last question, why are'nt samsung yet in a dominating position in the SSD range.
All in all though, Samsung must be beaming over how fortunate they have been as of late, they look like they have had a really good run with hard drive releases lately, their F1 range has shot straight into the spotlight probably becoming WD's largest competitor (don't think that the F1 Raid range have been too successful though) and now they're having a very good run with SSD's. You've really got to admire the company's enthusiasm considering where they were 2 or 3 years ago.
