Western Digital WD4000FYYZ - HDD RE 4TB 3.5 SATA RPM 6Gbs 64MB

Product Information

When it comes to data recovery one of the most common problems Western Digital WD4000FYYZ Hard Disk Drive experience is burnt circuit board(PCB). So if you will need to match a replacement PCB, it is important that you note the “ Board Number” of your current circuit board in addition to the hard drive’s “ Model Number“.

We get a better idea of the supported features using FinalWire's AIDA64 system report. The table below summarizes the extra information generated by AIDA64 (that is not already provided by HD Tune Pro). Western Digital offers three Enterprise class drives to their consumers, RE – SATA 6Gbps & 3Gbps, RE – SAS 6Gbps and Xe – SAS 6Gbps. Both the RE classes are a 3.5″ form-factor and range from 250GB to 4TB capacities. The Xe class, which is an Ultra-fast SAS drive, comes in 300GB to 900GB capacities. The Western Digital RE 4TB stands at top of Enterprise class capacities for Western Digital. Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4K read and write speed and 8K 70/30, which is commonly used for enterprise drives. We also included two legacy mixed workloads, the traditional File Server and Webserver, each offering a wide mix of transfer sizes. This answer explains why some WD RE drives do not work as a replacement or upgrade for some WD Sentinel products, despite having a similar model number to a supported drive.*END For a complete list of drives that work as a replacement or upgrade for the WD Sentinel DX4000, RX4100, DS5100, or DS6100 please see the table below:If purchasing from a location other than the WD Online Store, please refer to the Drive Part Numbers column. Western Digital RAID Edition (RE) 4TB Enterprise drive takes the RE family to the 4TB capacity limit. The new drive offers a SATA 6Gbps interface with RAID-specific, time-limited error recovery (TLER), dual actuator technology, enterprise build quality to name a few of the features that make the Western Digital RE’s ideal for Enterprise users looking for the fine balance between performance and capacity. The WD Sentinel devices support specific WD disk drives (RE or SE class) that provide the highest reliability to customers. Although WD Sentinel family of products will accept other drives, WD highly recommends the use of preferred drives listed in this article.

The Western Digital RE hard drives have little difference in appearance from their consumer counterparts, except the nice bright yellow label stating “Enterprise Storage.” It is a nice touch just in case you have a bunch of drives in your spare parts box, as it would be difficult at first glance to tell what is Enterprise or what is a Consumer Western Digital Drive.The Western Digital RE SATA 4TB provides fast, and reliable performance with the largest available capacity and will give enterprise users a density boost for bulk storage applications. Examining the 8K 70/30 average response times, the Western Digital RE 4TB maintains less than 1000ms average response times up through effective queue depth of 24. It spikes to slightly above 1600ms at an effective queue depth of 32. It is possible to use hard drives that are not on the list for the DX4000 and RX4100. It is recommended that replacement drives in a RAID configuration match the original drive as close as possible. For example, if the failed drive specifications are 7200 RPM, 64 MB cache, SATA III, 4TB, the replacement hard drive should have the same specifications. WD hard drives are engineered with Data Lifeguard Tools, a combination of hardware and software that work together to provide you with the best performance and reliability you've come to expect from WD drives. The Data Lifeguard Tools software includes the Acronis True Image WD Edition (ATIWD) which will assist you with your hard drive installation and management; and the WD diagnostic tool which allows you to perform different diagnostic tests on your drive.
