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

I used this 4t hard drive for my surveillance cameras, it worked perfectly for a couple weeks and then stopped recording, I’m really disappointed

Funciona a la perfección, 4 teras me dan casi un mes de grabaciones, fantastico Cuento con 8 camaraspara referencia

The HDD was very easy to install in my reolink NVR. I just removed the old drive and installed the new drive without formatting it. It was plug and play. The old drive lasted for about 4 years. Ill update this review if it fails anytime soon.

This plug and play replacement for a failed NVR hard drive was exactly what I hoped for and did not disappoint.

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.

Bought this at a great price, but came with bad sectors and no-functional

Nothing

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.

Works in my harbor freight 4K NVR surveillance system.

I install home camera systems. Most home recorders come with 1tb drives. With 4 cameras running 24/7 that is only a few days of recording time. I installed this in a 6 camera system and it extended the time to 25 days.
