xfer speed nice. Have had only 2 weeks, so don't have a long term evaluation. So far so good.



SanDisk and Samsung are the only flash drives that have not failed on me. Samsungs are about 50% higher in price. so I usually buy SanDisk. I have never had one fail and some I use every day. Don't ever buy the no-name drives. The ones is have tried have all failed. Fortunately, they usually fail within the first couple of uses. Lexars fail after you use them for a while so you lose many files.
