Bests & Worsts Reviews from Amazon

I am really unhappy with the deceptive way this flash stick is described by SanDisk. Windows 7 only supports booting from USB devices that are 'removable', and this flash stick has a bit set telling the OS it is a 'fixed' drive. What possible reason, except for incompetence, can there be for SanDisk to not specify this parameter? I had put this product in my Wish list a while back when there were only a handful of reviews and no mention of it being a 'fixed disk'. Last week I moved it from the wish list to the cart without rereading the reviews. I feel I have been blindsided by a deceptive and incompetent company since my main purpose in buying it was to use it as a bootable device in Windows 7. To add insult to injury a SanDisk representative added a smarmy comment to one of the unhappy reviews saying, oh yea we changed it from 'removable' to 'fixed' without offering any explanation of why the spec didn't change. He then continues, there is a way to make it bootable, but we aren't going to tell you how to do it! Can you believe such a response? I take this as a company that has no respect for its customers. I ran some head-to-head speed tests copying a folder (890 Mbytes, 5,300 mixed files) between my Crucial M500 SSD and this SanDisk flash and a fast PNY Turbo USB 3, which is substantially cheaper than the SanDisk. Both flash sticks were connected via a USB 3 port (on a plug in card). While all three of these flash products are fast, the folder copy time varied by a factor of 19! Baseline was the copy time for the SSD writing the folder to itself: 10 sec. Writing the folder from SSD to flash sticks: 71 sec (SanDisk) and 191 sec (PNY). Writing folder from flash sticks to SSD: 25 sec (SanDisk) and 18 sec (PNY). In other words in reading the cheaper PNY was faster than the SanDisk, but in writing the SanDisk was nearly three times faster than the PNY.
