Muy bueno

Works as it should. In service for several months now with no issues

Used this product as an external drive to my reolink dvr. Worked really well. Just have to use an external housing with esata connection

Buon prodotto adatto per videosorveglianza

Works great for my video surveillance system. Easy to install. I would recommend it.

Lasted less than 3 months in a NVR. Reformatting did not help. It constantly returns an error status. As SSDs have come down in price since then (and work perfectly fine in my other NVR), this is probably the last hard drive I will ever buy. SSDs are still more expensive, but that is a trade off I am willing to make. I have had many failed hard drives (usually after a year or more, though), but not a single SSD failure that I can think of. The hard drive was also noisy with constant thumping noises when it was originally working. Noticeable and annoying in a quiet office. It was warm to the touch even when the only thing it was doing was sending a error status back. The SSDs are much nicer to live with.

Does what it is supposed to

Estoy muy satisfecho con el producto

The drives a piece of junk. DOA. The motor doesnt even seem to spin. It was purchased supposedly new from HardDriveGeeks through Amazon.
