WD Purple 4TB Surveillance 3.5" Internal Hard Drive, AllFrame Technology, 180BT/yr, 256MB Cache, 3 Year Warranty

I always use this hard drive, and it has proven to be extremely reliable over time. I’ve installed many of them, and faulty units are incredibly rare. The performance is consistent, making it a dependable choice for various needs. If you’re looking for a hard drive that delivers reliability and peace of mind, this one is an excellent option!

I bought these as I was building a home server/nas and wanted a raid 5 setup (min 3 drives) and they were going into a Jonsbo N1 case which is really small and doesn't have really the best airflow through the drives ( If you look at the pic the highest temp drives are directly behind the fan hub ). These drives however are designed to run constant and hotter than most (upper limit is I believe 70 degrees), they're not the fastest drives but as I'm using these for serving Movies, Music and TV Shows And running Home Assistant i just wanted the reliability. I'm running them via OMV6 in low power and low acoustic mode (I have no idea whether these drives support this but they are virtually silent and the server sits approx 2ft away from me in my office) These came in sealed WD branded boxes in bubble wrap with silica desiccant and all checked out with 0 hrs power on time and no bad sectors etc (Brand New )... ( I got caught out buying from China and received a drive with a 2023 label but over 5 YEARS of runtime !!! ) Will be purchasing 2 more very shortly to replace my other old drives. Recommended.

Purchased for a replacement in my CCTV swann system, for the price paid I was able to double my storage too from 2TB to 4TB. The transfer from broken orginal system HDD was really easy took no more than 10min once attached and formated it began recording straight away. Happy with the drive and cost I paid for 4TB

Absolutely rubbish, I have installed the disc and dvr formated for me and went abnormal. Completely damaged and start rebooting my camera all the time. Also I’m waiting for my money back 3 weeks already!

This is still in my NVR and has been recording and overwriting with no errors or issues for over 10 months

Still working today

very good

I installed two in a new Hikvision DVR and they initialised quickly and have run smoothly and silently ever since. Cannot comment on longevity, but they are Purples!

Utilisé dans un NAS Synology

Came as defective, the HDD can't be started. It is either defect from factory, but likely mishandling by Amazon. The packing came ok-ish but with a lot of deformations.

Fungerar som den ska och den känns relativt snabb.

This is a very reliable drive; I have three and they work great in both my camera system and my computer. Since it is basically plug and play there is no issues with installation. These are not the cheapest drives but then again you get what you pay for, and these are definitely worth the little extra cost. They seem to last forever, got one that is 6 years old and is still working without a hiccup. Since these are a 4 TB drive, they actually hold about 3.86 TB of data and are pretty quiet compared to other drives I've had in the past.
