  geizhals.at also finds 32GB version for 32€. Although i dont think many people will buy this.

  "The StaticDataRefresh technology monitors the error rates and when a preset threshold value is reached, the data will be rewritten to restore the correct cell charge level. I suspect all SSDs do this because it's vital to ensure the health of old data, but it's the first time I've seen it mentioned in a data sheet."
  
  I've also believed this for some time. This is a little off-topic, but doesn't this mean that TRIM is more important to drive longevity than is widely believed? Sure, garbage collection and over provisioning can usually maintain a drives' performance levels, but if the drive is re-copying around unused blocks, then this seems like a problem. (I'm looking at you, Apple!)

  Technically yes, because the drive would be rewriting invalid (i.e. deleted) data as well. However, even without TRIM the drive will know what pages are invalid once the OS writes to the same LBAs again. The invalid pages will then be deleted sometime during garbage collection, which will return the drive to "TRIMed" state (i.e. no invalid data).
  
  It's basically the same with TRIM too because the drive doesn't necessarily erase the data immediately (i.e. data will initially be written to OP space). TRIM merely gives the drive a heads up and the data can be deleted when appropriate, whereas non-TRIM system will give the heads up when there' already new data coming in.

  Anyone have an explanation for how the middle 256GB size used the most power in this test?
  (or was there a typo?)

  with new OCZ prices I'd rather go for Arc... http://www.kitguru.net/components/ssd-drives/leo-w...

  I've been waiting for this review for months. These drives were being showcased inside a low end server at Computex. I bought for 512GB drives and put them inside a HP server, connected in RAID 5 to a P410i controller.
  After a few months I started experiencing one drive failing every week. It all went downhill, as the failures started ocurring almost every day.
  I removed those drives and they are now working fine inside laptops.
  Transcend support told me they could not provide any support, as these drives were not tested in server environments.
  
  Although these are working fine and fast in laptops, I was a bit disappointed that they show it running in servers at Computex and then fail to support that same scenario in the real world.

  Please read "I bought *four 512GB drives".
  Also, I'd like to add that when placed in laptops, the drives reported 100% health as per Transcend's app.

  "the SSD370 is also listed at even lower prices on Amazon Prime right now"
  
  What about regular Amazon? I don't have a Prime account.

  What firmware was used on the Plextor M6S during testing, or are those old historical results provided for comparison testing? Newer Plextor firmwares (released over the last 6 months) are supposed to have addressed their service time issues, and it would be interesting to see Crucial / Micron's M550 and M600 with their recent (early Jan 2015) firmwares that hopefully address the same issues.

  Thanks for the extensive review. I recently purchased the Kingmax 256GB SME35 which has the same controller and memory. So far the drive has been excellent.
