Pros: Quite, no vibration in my external hdd enclosure, and great transfer speed compared to older drives even at 5400 rpm.

Cons: Bought 2 and 1 failed while formatting but newegg replaced with great rma service and the replacement is running great.

Overall Review: Hope they last, they are only on about 30 minutes or less, long enough to backup movies and not that often.

Pros: Previous review in September 2014 5 eggs, price/performance good. Read/Write about 50/25MBps according to Windows 7.

Cons: 8 months after previous review, 2 years after purchase died, good while it lasted, not so good considering it has a lifetime warranty.

Overall Review: I forgot to register it and threw away the package with the serial number on it, so can't tell you if Adata's RMA service is any good.

Pros: My favorite OS till Win 7.

Cons: Did get hack attacked a lot.

Pros: Price and reads and writes large files like backup dvd's faster than rated speeds and still about twice as fast as the 16GB version if you write lots of smaller files.

Cons: none.

Pros: Very happy with this since XP.

Cons: none.

Pros: Nice for the price.

Cons: Could use more padding for my behind.
