## Description

Purple WD43PURZ - Hard drive - 4 TB - surveillance - internal - 3.5" - SATA 6Gb/s - 5400 rpm - buffer: 256 MB

Review: Reliability - I have used these drives for over 10 years without issue. The existing one was 7 years old which is approaching the reliability end of life for this drive type although nothing was wrong. The first drive I had to send back as faulty but this was not the companies fault as although the packaging was marked fragile it didn’t have an adequate amount of packaging protection and the Royal Mail postman posted the item through my letterbox so it was probably the fall that damaged the delicate rotor arm.
Review: Great replacement - 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

## Features

- WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.
- WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications
- Supports up to 180 TB/yr workload rate(3) | (3) Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
- Support for up to 16 bays(7) | (7) 1TB through 2TB support up to eight bays; 3TB and above support up to 16 bays.
- Tarnish-resistant components(6) | (6) Tarnish resistant components for capacities 3TB and higher.

## Questions & Answers

**Q: can it replace older hhd in nightowl dvr**
A: Yes. This hard drive is compatible with all recording units.

**Q: What is the difference between 3tb purple wd30purz and wd30purz, very confusing?**
A: Absolutely nothing. They are the same.

**Q: Is this compatible with annke surveillance camera system 8ch 1080p lite h.264+ dvr with (8) hd 1080p outdoor weatherproof cameras cctv security camera**
A: As the owner of South Jersey Surveillance Systems, I can assure you that any WD purple or Seagate Skyhawk hard drive is the appropriate type of storage drive for any and all DVRs and NVRs.

**Q: Whats the difference between this and the red plus?**
A: WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue.

WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap.

WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs.

WD Red is a NAS drive. It’s optimized for NAS systems.

WD Purple is for surveillance. Advised for 24/7 operation.

WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.

### ⭐⭐⭐⭐⭐ WD Purple for NAS drives? YUP
*by P***R on 14 September 2023*

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.
