WD 4 TB Surveillance Hard Drive - Purple

Last drive (WD 3T blue) was great, as (I hesitate to say incase they get complacent after their excellent work - was the previous WD 2T RED & WD 2 T Green). I use for reliable storage but this time I needed a drive for possible OS & storage (win 7, XP 64 Pro). Over the past 18 years various drives have dominated (in 2000 I would not best a WD drive). Now after years of use the Seagate Barracudas & definately Maxtores are mostly dead. The Hitachis are balanced between fine & quite problematic. The WD's I have bought in the last decade are still semless:Red: Perfect - used as storage for 8+years in an external enclosure (Probox - god i miss these indestructable esata boxes and the old prices)Blue: Perfect - used as a drop in for the Icy Box Dock. 1 Year. Solid & no real speed difference over e-sata (love e-sata)Green: Perfect - as drop in again this is still solid, reliable and holds e-sata speed (not much in it but blue & red seem very marginally better)Purple: Great/Perfect - they really know what they are doing. I tried this for a change. Good E-sata speed, very Reliable as to date. Well built as norm, nice drive.At the moment I love n trust WD's work. Have not tried black but do not see the need with PC speeds non server. The rest are all excellent. Purple? I guess time ...several years will tell (or use in much security recording as designed...still awhile I would say). Green are fine, red n blue I feel more comfortable with, as too do I purple. A larger size may lead you to their proposed red or blue, and for a speed margin perhaps black (not needed for regular home PC). Nice to have options but better to have ones data still accessible. For now I don't look elsewhere, I just check price & needed size (I don't need NAS so only pure storage drives I get will be over 2T - this is the tec that does move on...& prices get better). Cheers WD... lifesaver.

Have installed in my Annke DVR, all working well so far, good value for the price compairing with the other 4TB HDs out there.

It's been running non-stop for over a year now with no hiccups. So, seems good so far.

Eventually fitted the new WD Purple drive into my new DVR base unit and it seems to be working as it should. Only time will tell as to whether this dedicated surveillance hard drive will prove a good buy and batter than the WD Green drive fitted in my old ailing Swann DVR unit.

Currently working well in a Swann CCTV system. Loads of space, plenty of speed.

Designed for Surveillance DVR, works a treat. I have used WD drives for 20+ years and only ever had one go faulty and despite it being just out of warranty, WD replaced it but it is worth getting the extra years warranty for £19.99 if you didn't purchase it as part of the price :) If I wasn't confident with WD, I wouldn't be planning to purchase 4 x 4Tb WD Red NAS Drives via Amazon.

Working great in my pc no noise at all passed all the self tests and a full surface test. The Drive is to replace my over 4 year old WD green which has been running nearly 24/7 and is still working now 08/01/19 and is now over 6 years old hope this lasts as long time will tellVery well packed which was a surprise from passed experiencesjust have to see how long it lasts but very happy with it so farUPDATEFAILED just over 2 years oldReallocated Sectors Count 131 in no timefailed read test elementon all 3 self testscrashes pc when trying to read from diskAnd to find out no warranty Out of Region on WDs website2nd time trying to update my review amazon not updating it

Used in 24/7 cctv system, 3 full he cameras constantly recording to the drive with no issues. I have software limited it to only record upto 95% then record over and it's fine. Ideally you should raid them so if you do get a drive drop you won't loose footage but these drives seem very reliable. Also use reds for file storage and have 6 of them ranging upto 4 years old without issues. I replace drives every 5 years regardless but never had a wd drive fail on me
