I bought this to use in a server build as an OS boot drive. My OS (Linux-based) installs usually take no more than 4-5GB, so this is total overkill. But this size made it also useful for other purposes and at the price I paid, it was the best $/GB.
I read elsewhere that this flash drive has a tendency to get really hot. In fact, because of such reviews I read, I was considering the equivalent Samsung model. In fact, I got both for comparison. What I found out is that in a USB 3.0 slot, under heavy writes, this drive does indeed get hot, but in my opinion not so hot that you can't handle it with your bare fingers; some might have more sensitive fingers than I so YMMV. When compared to the Samsung option, this drives seems to have better sustained performance, where as the Samsung has a tendency to slow down under sustained writes (like if you're transferring a 30GB file). However, when I've used this drive in USB 2.0 slot, albeit with slower performance, it does not get hot at all. So, if you're worried about this thing getting hot, consider the above.
Either way, as an OS boot drive, which typically has a lot of smaller files they both perform well. I've been using this SanDisk one in the onboard USB 2.0 slot of a Supermicro motherboards to have a bootable OS that I can use to test out the hardware and run diagnostics. It has worked great in that capacity for quite some time now. Since it has such a high capacity, it allows me to install all the various hardware diagnostic tools I need for multiple platforms.
I've been considering partitioning this drive so I can triple boot Linux, FreeDOS, and Windows so I can have access to diagnostic tools from all 3 OS platforms. The FreeDOS is especially useful for doing BIOS/Firmware flashing.
