Pros: Windows 10 recognized the device as a hard drive from a PCI to M.2 adapter. On an older motherboard, you can use this device as a secondary hard drive though the PCI to M.2 adapter as long as you are running Windows 10.
Cons: Motherboard with no M.2 interface will not recognize the device from a PCI to M.2 adapter. No way to set this as your boot drive without a M.2 interface on the motherboard. Windows 7 does not have a driver for this device when in a M.2 to PCI adapter.
Overall Review: I hoped to install this in a Gigabyte motherboard I purchased in 2014. But without a M.2 connection, the motherboard did not detect the device in the BIOS. Without the motherboard recognizing this device as a hard drive, I could not set it as the boot drive. I could have used it in the PCI to M.2 adapter as in auxiliary drive in Windows 10, but I needed it to be a boot drive.
Pros: I like the way it looks and feels.
Cons: Write speed is disappointing, but I'm seeing reviews for other flash drives that note write speed as being slow. I use it to create a copy of a file that's approx 60GB and it takes an hour or more to copy.
Overall Review: Has a sleek appearance. Its small size makes it easy to use in ports that are close together. If you want to load large files, you'll need to format it to NTFS.
