I noticed you are using QD=4 in your ATTO benchmark run. Were you able to achieve this QD in any of the other benchmarks? If not, then how do you explain BluRay write and PCMark8 writes being faster than CrystalDiskMark sequential writes?
The 'throttling' is taken into account in the benchmark numbers. Our robocopy tests actually transfer the data contents to and from the drive three times each and the average is reported. The three different workloads are executed in succession - This process takes 30 minutes to 1 hour for a total data transfer of more than 250 GB. Workloads beyond that are not in the realm of what a flash drive might be used for.
The throttling and heat issue are probably why Mushkin doesn't promote these as portable OS drives. I still stand by the conclusion that it is one of the fastest drives for the typical flash drive use-case.
I'm super stoked about the emergence of the category of SSD-on-a-stick. They're a huge boon for bootable USB tools or OS install drives. In a pinch they're great for large file transfers too. I've had a SanDisk Extreme USB 3.0 for a while and was wondering how it compares (in your workloads) to the above products, specifically the Corsair Voyager GTX.

Can be get a review of the Sandisk CZ80/CZ88 drives?prasun - Tuesday, November 11, 2014 - link
Which driver was used for these tests? Was it a UASP driver?ganeshts - Tuesday, November 11, 2014 - link
The drives are connected to Intel's PCH USB 3.0 port. It is indeed UASP enabled.prasun - Tuesday, November 11, 2014 - link

robocopy's default queue depth is 8.eddieobscurant - Tuesday, November 11, 2014 - link
come on, i was expecting you to acknowledge the issue that it gets too hot and throttles after a whileganeshts - Tuesday, November 11, 2014 - link
