WD Red 6TB 3.5 Inch NAS Internal Hard Drive - 5400 RPM - WD60EFRX

Product Information

FANS: 3xFractal R3 120mm - 3 Front, 1 Rear. Corsair Commander Pro to control the fans (see script and code) Note that the width of the access time graph is about 8ms which is the max rotational latency of a 7200 RPM drive. However, WD's spec sheet states that the drive's performance is "5400 RPM class".

Or of course third option would be to slowly replace all three of the exsisting WD60EFRX drives I have with the newer WD60EFAX SMR version one by one. This option seem the least value as I would really be swapping out 3 good drives for no reason. Are you sure that WD hasn't changed the small Purple drives to SMR? These prices are almost the same as the WD Blue SMR drives. Turns out while both are offered as RED drives the EFRX is native Western Digital, EFAX is a drive technology acquired as part of Western Digital integration of Hitachi Global Storage and built in a different factory and probably has many other differences than just cache. The local distributor did not have WD60EFRX available and offered me a RED WD60EFAX at the same price which was supposed to be the same, newer, but a bit better - more cache. The logic was it wont be any better in your NAS but it wont be any worse.

As WD Red is the only 5400 rpm disk on the market it isn't the best choice if high performance is expected to begin with. They are mainly bought for being NAS compatible, not using a lot of power, running cool, running silent and being relatively low cost. All available alternatives on the market are 7200 rpm so most likely make more noise, run hotter and use more power but are generally faster. So far none of these 6TB Red drives have failed and compared with the older 2TB drives very fast indeed.

Use this modified string, for example "HUH7280??ALE60?" to search for model name in the tables below. Any capacity drive is from the same family as the found model name and all the fields from the found table row are valid for it, meaning HUH728060ALE601(6TB) and HUH728080ALE600(8TB) are from the same family. xLSI Logic Controller Card 05-25699-00 9305-24i 24-Port SAS 12Gb/s PCI-Express 3.0 Host Bus Adapter If your drive is not found in this guide, please send me pictures from both, the label and the PCB sides of the HDD (or full model and serial number if you cannot take the pictures) and I'll try to add your drive to the guide.

WD60EFRX Western Digital Red 6TB 5400RPM SATA 6Gb/s 64MB Cache 3.5-inch Hard Drive.I'm using Raid 5 I'm a little under half full at about 8TB and get about 75MB/s read 55MB/s write on a video file copy which is well under the theoretical throughput (125MB/s) of Gigabit Ethernet. Error recovery controls: WD Red™ NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Use this string "??L0BN?" to search for model name in the tables below: can be found as WD60EFRX-??L0BN?. Any capacity drive with the name "??L0BN?" is from the same family and all the fields from the found table row are valid for it, meaning model WD60EFRX-68L0BN1(6TB) and WD40EFRX-00L0BN0(4TB) are from the same family. x WD Green 3D NAND (120GB, 2.5") - - Boot drives (maybe mess around trying out the thread to put swap here too link) If your drive follows HGST model naming convention, then you would have to replace one or two capacity encoding numbers and the very last number in the model name with "?". For example HUH728060ALE601 would become HUH7280??ALE60?, and HUS726T6TALE6L1 transforms to HUS726T?TALE6L?.

SMR does result in lower performance, but it enables cost savings that are attractive to some users, and if used in the correct types of workloads, those savings are worth the exchange of gaining access to deeper capacity. However, using SMR tech for desktop and laptop boot drives will likely remain a topic open for debate, as their underwhelming performance in sustained random write workloads could hamper performance in standard operating systems. Shingled Magnetic Recording (SMR) technology helps hard drive manufacturers to produce HDDs with larger capacity.That's a welcome announcement for users who want to make the decision of when, and where, to use SMR drives in their systems and NAS arrays. Then modify this short model name, replacing first two characters and the very last one with "?", for example 68L0BN1 would become ??L0BN?. Thanks @sretalla thanks for the info re purples... I'll keep that in mind when I look at expanding if the pricing works... not too attractive at this moment. https://www.tomshardware.com/news/sneaky-marketing-toshiba-seagate-wd-smr-drives-without-disclosure Introducing the innovative Western Digital WD60EFRX-68L0BN1 desktop hard drive, designed to provide unmatched reliability and outstanding performance.

It is what it is but just a warning that while the "Red"branding may be the same, the drives arent. These new drives seem to be an upgraded version of their older CMR drives that used the same recording technology. When they silently replaced CMR with SMR drives they had more cache available. Now they have matched the cache size with their SMR drives. In a RAID situation, you will not benefit from this cache since all data is written randomly across many drives. But it is interesting that their speed has been increased from around 150 to 170 MB/s. If you have older drives that are slower you will not benefit from this. But if you have a new NAS then certainly choosing these faster drives would theoretically improve NAS speeds. In the existing setup, the speed will be as fast as the slowest link in the chain. If you connect via 1GbE LAN then you will not notice a speed difference anyway. WDC naming convention: all model names in this naming convention start with letters "WD", WDC full model name would aslo have a dash, for example WD60EFRX-68L0BN1. I am in the looking to replace my WD Red 3TB drives with WD Red Plus 6TB drives (making sure CMR tech is used). Now i noticed that a new WD Red Plus line has entered the market in 2021, namely the EFZX series with 128mb cache instead of 64mb cache currently used by the EFRX series. HGST naming convention: all model names in this naming convention start with letters "W" or "H", and there is no dash in the model name, for example HUH728080ALE601, WUH721010AL42L4.Compatibility: Unlike desktop drives, these drives are tested for compatibility and optimum performance. As I write this I can see a pile of 9 similar hard discs, all made by Seagate or one of their badge engineered names. They are all faulty and in under 4 years. Two 5 year warranty Seagate drives failed but were replaced under warranty. Also on the pile there are two WD discs, one was over 7 years old and the other almost 10 years old when they failed. We have 20+ WD disks in use, mostly in NAS units running RAID and on 24/7 and the last two remaining Seagate units which I would only ever use in a RAID array as I don't trust them. This is a review of a WD disc, so I expect it to last well beyond its warranty period and would recommend to all Aiming to mostly replicate the build from @Stux (with some mods, hopefully around about as good as that link) Ideal for Home Offices, Power Users, Small to Medium Businesses and Consumer/Commercial NAS systems drtweak said:Yea think I'll be buying Seagate now. They are even a little cheaper.Seagate was doing the same thing: https://www.tomshardware.com/news/sneaky-marketing-toshiba-seagate-wd-smr-drives-without-disclosure
