## Description

WD Purple Pro drives are designed for new generations of high-end AI-enabled recorders, video analytics appliances, deep-learning servers and cloud solutions that can benefit from high-capacity storage with high performance and additional workload capability. WD Purple Pro drives feature AllFrame AI technology, which helps reduce frame loss, improve overall video playback, and not only enables recording of multiple streams per camera but also supports up to 32 AI streams per drive for deep learning analytics within the system. WD Purple Pro drives also feature enterprise-class performance, data integrity and drive reliability, especially in larger-scale systems and enclosures where operational vibration is present.

Review: NICE HD ;-) albeit they give a fairly loud thumping sound - This is one of the many WD Purple label Hard disks that I have ordered. They are great drives, very reliable and fast. I use these WD purple drives in my NAS drives. Just install and forget about them ... :-) From my past experience, these drives will go many years in always on situations without a hitch. Last NAS I had some HD running non-stop for 10 years. Only upgraded the NAS for more speed and installed WD hard drives again for maximum capacity and their bulletproof reliability. Only caveat is they have this continuous fairly loud "thumping" sound. I just ended up placing the NAS drives a little aways, so that the noise of the HD's would not disturb. Highly recommended!!!
Review: Use these beasts for my personal 3D animation mini-render farm - These robust, high speed, "24-hour video recording" 18TB HD's make for a terrific solution for churning out monster-sized file renderings from 3D software (Maya, Houdini, etc). The things are absolute beasts, and their resilience and beefiness is exactly why I use them for my "small" personal render farm (one 2-disc 36TB RAID-0 for smaller renders, and a 5-disc 90TB RAID-0 tower for bigger renders) in my home office. Sure, I could have gone for the "Black" version that a lot of gamers prefer (if they are using SATA instead of SSD), but these drives are larger capacity with the same speed, and built to handle even more stress. Should last me several years, no problem, but I will collect a couple more to keep on hand in case (or when) any of the originals fail...Eventually, yes, I'll likely go all-SSD in the future, but not until they are at the same price-point, with the same-or-greater TB size, and equally "indestructible". Brilliant slabs of hardware.

## Questions & Answers

**Q: Can it be installed vertical instead of horizontal inside my lorex nvr?**
A: I don't see any reason why not.  Mine is installed in a Lorex NVR, but as I recall, it mounts horizontally.

**Q: Are these OEM or retail drives?**
A: OEM

**Q: Will this work in a Desktop Computer ?**
A: I had a bunch of issues with this in my desktop... I ended up sending it back and getting  two of these Seagate FireCuda HDD 8TB Internal Hard Drive HDD - 3.5 Inch CMR SATA 6Gb/s 7200RPM 256MB Cache 300TB/year with Rescue Services (ST8000DX001)

**Q: In case of failure, should we contact the seller or the WD?**
