I bought these on sale for under $20 which makes them a great choice for the price. I tested all five drives. Read speeds ranged from 60MB/s to 100MB/s on five different drives. This is quite a wide spread since it's probably the same hard drive. Even at 60MB/s they are worth their price. Write speed is another matter and all disks worked at around 25MB/s with a difference of only 1-2MB. Not the fastest, but acceptable in this price range. That makes me think about the longevity of these devices. The time will show.
