    Wow....35TB writes. A 2009 Intel X25E has like 2-3 PB worth of write cycles and the M600 512GB has 300TB worth of write cycles. 35TB is pathetically low.

    Would rather opted for a good old-fashioned Hdd instead of this new garbage :D.

    Micron was using 72TB rating across the entire consumer lineup for a while.

    The write endurance rating is just a warranty limit. There's no way the actual hardware can be this weak.

    I think that 35TBW is OK for the 120GB size. I'm approaching 15TB in 21 months on my 840 EVO. I also find it interesting that they claim 520GB write - 120GB drives usually have relatively slow write performance.

    The writing is SLC cached.

    No such thing. Pseudo-SLC (and even then, still pathetic total write limit - Samsung just wanting to warranty the drive, right before failure is imminent).

    I think it's appropriate to call it SLC. The NAND cell itself is analog. It doesn't have layers. The mutile-layer write and read behavior comes from the controller and is only logical from the NAND's perspective.

    The TLC NAND itself is not somehow magically weaker. The PE is low only because the target voltage range is smaller. If you use TLC NAND only as SLC with voltage and pulse duration that fit this purpose, its P/E should match normal SLC, but capacity is much smaller.

    No. Not even close.

    Pseudo SLC has some benefit when compared to MLC and TLC, but compared to true SLC - it is like comparing a Ferrari to a Pinto.
