  • Write Speeds very Slow

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I've tried it on 2 computers. Write speeds on a large file are maxing out at around 15 MB/s. Note that with less then 1 gb it seems faster. It's probably using an internal buffer. Yes, I still recommend it. It's large and was cheap. You just have to know what you're getting. It is tacky that the product page only lists the read speed.
