SSD Write Endurance 25nm Vs 34nm

[Christopher]

Christopher: Someone has to help me work out if these samsung 840's are any good!

I'm impressed with the read speed. To be certain, the write speed is not in the 830 's class, but considering TLC has seven guard bands and 8 voltage levels, I think it's a miracle it works at all! It's still supposed to be 3K PE cycles (I think) but the MWI is based on 1K PEs.

Sequential and random reads are significanty better than the 256GB 830, while write speed is worse than the 64GB 830. All writes are limited to about 130MB/s. All in all, I'm incredibly impressed -- it's faster than many of the SLC drives I have, and I don't just mean the MTRONS.

THe 830 is up to 12.5 trillion LBAs written. It's not significant in any way, except it sounds like a whole lot.
