AS-SSD Incompressible Sequential Performance
The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.
Although we saw the 830 take a backseat to the SandForce based offerings in our compressible sequential write test, the roles are reversed in our incompressible write test. Most huge sequential writes are going to be incompressible in nature (e.g. moving a H.264 movie around) so these numbers are quite relevant.

problem is everyone else has had more problemslanderf - Saturday, September 24, 2011 - link
Speaking of reliability, aren't those the old results on the M4?Anand Lal Shimpi - Saturday, September 24, 2011 - link
Thanks for the heads up, updated :)Take care,
Anand

...anyone noticed? Though this one would be nice for like a x220 that only takes 7mm drives but with power consumption more than double of a crucial m4 especially at idle...basically kills it for mobile use.MrSpadge - Saturday, September 24, 2011 - link
Yeah, it almost approaches 5400 rpm HDD idle levels..MrS

Update: Storagereview.com measured idle power consumption of a 256 GB drive to be just 0.31 W, which is much better and just normal (or even good).MrS

Once again, for mobile the issue is not IDLE power use, it is PEAK power. If your system is not specced to handle that peak power, it will crash whenever there is a sequence of back-to-back writes.7Enigma - Monday, September 26, 2011 - link
I think you're misinterpreting his comment. IDLE power matters for laptop users from a battery standpoint. Yes it's going to be a small % difference due to the large(r) draw of the screen, cpu, gpu, etc. but it does add up. We do understand your comment about crashes but I think the OP's comment is in reference to something that is going to ALWAYS be using more power than a competitor as being bad.I do not know what burst power consumption is on mechanical HDD's but would imagine they are at or above what even the most power-hungry SSD consumes. This would be an interesting mini-article Anand!

Burst on SSDs tend to use more power than many HDDs.Alexo - Monday, September 26, 2011 - link
So what 7mm SSD would you recommend?
