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.

The item arrived promptly and worked like I thought it should. The only thing I would suggest to improve this item would be to ship it with a carrying case to hold the meter and the testing wires.
