The first such drive I bought as a backup medium before three quarters of a year. Since then, he came regularly to update the backups are used. Data loss I experienced one yet. This part is a little hot after prolonged use, but that has had no further consequences for me. Speed is subjective acceptable, not very fast, but especially for large files more than sufficient (lots of small files takes - as always with storage media - much longer). Easily compatible with Windows Bitlocker.
Price / performance ratio is good - in this amount of space you get almost anywhere else what favorable. Who wants it very fast, must stop touching some extra cash.
