Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5 - WD42PURZ

Good solid hard drive. If it performs as well as the other WD drives Ive bought over the years, I will be very happy.

Ottimo prodotto,consegna più veloce del previsto però ho riscontrato uneccessiva rumorosità durante la scrittura ,ovviamente da molto fastidio perché montato allinterno dì un nvr deve essere più silenzioso possibile. prima di questo cera montato un hd da 1tb sempre wd purple..silenziosissimo, valuterò se restituirlo perché il rumore si sente abbastanza.

Does not work

I needed more storage for my NVR, the manufacturer suggested another brand but had not tested this version. I saw that it was a performer in the testing data and after install I have had zero issues. The NVR interface was able to increase my storage and I am able to record much more.

Working perfectly

Bought this to replace a failed drive in a Reolink NVR. The r/w head seek sound is significantly louder than the old drive. The NVR is in my bedroom and constantly recording 4 streams of 4k camera video, so the sound goes on 24/7. You may want to find a quieter drive if you expect to use it in a similar situation and are sensitive to constant drive noise, especially at night when the house is quiet. Other than that quibble, it is doing the job.

Received 4tb HD earlier than expected from seller. Plastic wrapped HD shipped in unmarked sturdy corrugated cardboard box which was in a bubble-wrap sleeve. HD itself was suspended within the box by hard plastic inserts. WD HD was marked with a manufactured date of April 2022. Item is being used in a surveillance DVR. No issues, very quiet, showed just 3.6tb available during initiation but believe that being due to proprietary formatting by DVR. Very pleased thus far with product and seller.

This was a replacement for a worn out security camera HDD. Easy to install. It does NOT come with connection or power wires.

Nulla da dire fa quello che deve e non costa tanto
