Pros: Benchmarked at 250 mb/sec running on 3.0 usb port.

Cons: Died suddenly after 2.5 months. Pain to get warranty replacement from Samsung. Update: Samsung made me jump through hoops to return this for a warranty replacement and finally they sent me a cash refund claiming the drive was out of stock. It took me 3 email exchanges and two phone calls, all for a cheap drive that obviously has a high failure rate.

Overall Review: Would be afraid to buy again.
