Advertised speeds FALSE !!

But my key did not exceed 20MB / s write even on very large files. After extensive research, it appears that for the same key reference: 64GB CMFSL3B-there are at least two versions: a PMAP version and a version 1.00. You can not know in advance which you will receive and the difference is significant:

Version 1.00 has very good rates as those announced by the manufacturer and the PMAP version seems to be a version of "restrained" in writing that tops out at 20MB / s. I'm not the only one who found this (see Corsair forums).

Such a difference in my view is unacceptable for products intended to be strictly identical. Corsair was contacted about it ... for now no response.

If people want to respond to this comment by posting their key version (PMAP or 1.00 identifiable by AS SSD Benchmark) and max write speed (With H2testw 1.4 software). Remember to test the key on a USB 3.0 port
