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.

Cctv HD worked fine

So far so good, direct replacement for an old Seagate drive in the DVR box, old one out, new one in, auto format and away it goes. Seems to work fine, ask me in a couple of years! Old one lasted a couple (was a cheapy from auction).

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.

Have been using this disk drive for many years. It has worked well with no problems. Recommended

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.

Arrived quickly, well packed and absolutely new. Put it straight into my CCTV DVR, no problems, quiet running, working well for me. So pleased to get a good price and NEW, unlike many marked as "Seller Refurbished". What do they do?, open it up and vacuum clean it. Refurbishing is for a manufacturer not a seller. Won't hesitate to use this seller again, thanks

Only gave this 3 stars because of the PACKAGING! Very poor for a harddrive. The WD box is fine, but the outer Amazon box only had a bit of paper in it...I would have expected a lot of foam ect for a harddrive...Great product. If you pay someone to fit your CCTV system they usually just put a generic Harddrive in it, but I'd definitely recommend a WD Purple. My system feels a lot smoother on playback now and it should last a lot longer than the previous HDD as this one is made for the job. Can't go wrong with WD.

Western Digital社が、色分けでモデルの特色を区別する中で、紫色のこの WD Purple モデルは映像記録用に特化された『All Frame™テクノロジーによりストリーミングのパフォーマンスを向上し、フレームロスを防ぐ』モデル。監視カメラ用の連続稼働や各カメラ・チャンネル映像の同時並行でのアクセス、連続運転のための静粛性・低騒音のための低回転駆動を優先した、Seagate Pipeline HD シリーズや Western Digital の WD-AV シリーズの後継にあたる。最大８台のHDDで、同時に最大３２台の監視カメラ映像を同時並行で毎日２４時間連続で書き込むのを止めずに、そのまま確認のために映像を再生することもできるような使われ方を想定したモデル。データサーバーなどの高速アクセス・データ化けの致命度とは異なる設計で使い分けるのに好適。これを実現する、ATAストリーミングコマンドを意識したテレビ放送の全録機や、複数チャンネル・複数チューナーを同時録画再生するような HDDレコーダーには、アクセス速度を追及した WD Red や WD Black のような発熱の犠牲を連続して受ける副作用よりは、この WD Purple のように多少のデータ信頼性がなくとも静かでフレーム落ちはしない淡々と常時駆動するのに向いたモデルが良い。＜利用例＞東芝のレグザ・タイムシフトマシン(地デジ6チャンネル同時全録機)DBR-M190 では、２台入っている Seagate Pipeline HD ST2000VM002 (2TB, 5900rpm, SATAII, 64Mcache) が異音や書き込み不良を起こした際、２台とも WD Purple 2TB WD20PURX に交換することで正常動作を得ています。２台交換→タイムシフト設定を削除するため「初期設定／管理設定」→「設定の初期化」→「レコーダーの初期化２」ののち、本体録画用の2.5インチHDDのアクセスケーブルだけ抜いて再起動させ、タイムシフトマシンHDD２台だけで起動、デッキの初期設定をすべて終えて、本体2.5インチHDDを接続して再起動により、すべてのHDDが適切に認識されて復旧できました。

I'm sure there's going to be more than enough highly technical and lengthy reviews of this drive sooner than later here so I'm going to keep mine short and sweet.First, my home surveillance system:Aver 8-channel "Hybrid" HVR/NVR which employs two ports for IP cameras, and six ports for full D1 analog cameras. For the two IP cameras I'm using Vivotek 1.3MP units, and for the analogs I'm using six 750TVL Sony SuperHAD II / EFFIO DSP chipped units.My problem:I've owned this system for nearly a year now, and have always had issues with the two ip cameras not recording smooth video. Any time motion would occur to activate full fps recording the system would freeze/pause and result in lost frames. I was also limited to a slow 5fps with the ip cameras as well before massive stuttering would occur.My initial troubleshooting attempt:After spending an insane amount of money on all new network equipment, upgraded cat6 wiring, etc. nothing seemed to help. I even suspected the Seagate Enterprise drive that was originally supplied with the unit by my retailer, so they elected to swap it out for a Western Digital Green AV-GP drive, which at that time was supposed to be the latest and greatest for surveillance systems, but that didn't help either. In fact, I think it actually made things worse. So after spending countless hours researching over the course of several months, I stumble on a cctv forum and see that people are talking about this new "purple" drive so I go to the Western Digital website, and start investigating.........and I am SO glad I did.And, finally, the resolution:Having nothing to lose, and already owning, and loving, the Red drives in my home server (the drive this purple drive is based on) I went ahead and ordered a 4TB WD Purple drive to try to rule out the hard drive being my issue one last time, and low and behold, that's exactly what the issue was all along. Instantly upon turning my system on with the new purple drive installed, I saw a huge difference. CPU usage was down almost 30%, video was smooth, and there wasn't a single stutter or loss of frame that I could see. In case you're wondering why CPU usage dropped, it's because my system was being bottlenecked by the hard drive and it was trying to write to a drive that couldn't keep up with the task thus causing higher than normal CPU usage.Being in this position before I almost thought it was too good to be true so I didn't get too excited just yet, but after running for 3 days now, this purple drive hasn't missed a beat. It's near silent, runs cool, and has solved all of my stuttering and loss of frame issues. I am also now able to increase the fps of my ip cameras as well.I know I'm only 3 days into this, but so far so good. After using both the Seagate Enterprise and the WD AV-GP drives, this drive simply runs circles around them.I highly recommend this drive for anyone with a surveillance system, hands down.

Buen servicio, llegó antes de lo esperado y lo mejor de todo es que el equipo es de excelente calidad y adecuado para el servicio de grabado en DVR.
