King of SSDs 11/08/2012
This is the new performance king of consumer SSDs. I measured incompressible sequential writes (and reads) of over 500 MB/s with AS-SSD. It has QD1 4K random read speeds of 35-40MB/s. And its QD32 4K random reads and writes are over 300MB/s.
Has a 5 year warranty.
Uses new 21nm flash, and I cannot find a spec from Samsung on how many erase cycles it can endure.
If you hit the 840 Pro really hard (eg., fill it up with small random writes and keep writing) the performance degrades significantly, the same as other consumer SSDs. But at this price, I'd rather see it hold up better under sustained heavy loads, like the Intel S3700 enterprise SSD.
It is too early to tell if the reliability of the 840 Pro will be as good as the 830. I guess the 840 Pro will hold up well, but anandtech had a review sample die and apparently Samsung has not been able to explain the failure. Hopefully that pre-release model was an anomaly and the production units will be fine.
