  "cheese in in" -> "cheese in it"?

  The above was meant to not be a reply to yours. In general, there's isn't much, though, because with SATA, we're still stuck needing striped RAID to improve bandwidth. Assuming they can keep costs in check, the rapid shrinking,m and thus capacity increases over the next few years, will give us something much more useful. That said, it's nice that they caught up in terms of consistency.

  More relevantly, the 150TB warranty figure applies to all capacities. All things being equal, a 128GB drive with 150TB written will have the same amount of flash wear as a 1TB drive with 1200TB written.
  
  So in practice the 1TB model will have far higher endurance than 150TB. But its warranty will expire when its flash is only 12.5% worn. Samsung aren't the only manufacturer to have low TBW warranty figures; Micron/Crucial does it as well, with the same TBW figure for all drive capacities.

  Yawn. Another SATA 2.5" SSD.
  
  How does this compare to m.2 PCIe drives like the XP941 and M6e?
  
  Will we see m.2 PCIe NVMe drives before xmas?

  The 850 Pro is now in the Bench so you can compare the two easily:

  thanks, the XP941 demolishes this thing, why isn't it in the charts of this review? clearly PCIe m.2 would be on the radar for anyone looking for a high end SSD these days... ?
  
  it may not be readily available in the channels, but it is a taste of what is to come... personally I just got a 256GB plextor M6e PCIe m.2 for $220. It's easy to find in the market.

  I didn't want to put the XP941 in the graphs because the availability and support are relatively limited and it would have broken some of the graphs.

  just a quick dumb question:
  the bandwidth for SATA 3.0 - 6 Gbit/s is 600 MB/s right? so, it's 300MB/s read and 300MB/s write
  correct ?

• thesavvymage - Tuesday, July 1, 2014 - link

  no, its 600MB/s in total in either direction. you can max the 600 read if you arent doing any writes, etc. It isnt 300 max per direction, its 600 max for total data bandwidth

• zmeul - Tuesday, July 1, 2014 - link

  yes, I forgot to mention, duplex (at the same time) 300r+300w
