About this deal

As an industry-leading hard drive manufacturer, Western Digital stands behind their NAS storage solutions with the assurance of a 3-year limited warranty and world-class support services for hassle free data storage. False. Various sized drives come with various size caches. You can’t instantly detect SMR/CMR by cache size.

Lower operating temperatures - Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on NAS environments.NASware™ grows to 3.0 - Built off of our determination to deliver the best NAS experience, NASware 3.0 extends our promise by further optimizing WD Red for the NAS environment with added support for 6 to 8 NAS bays. WD Red now supports small NAS systems from 1 to 8 bays thanks to NASware 3.0, which further improves drive compatibility and reliability. At 48 TB of total capacity in an 8 bay system, WD Red expands your NAS experience. Western Digital’s exclusive NASware™ technology fine tunes drive parameters to match NAS system workloads which helps increase performance and reliability.

You may want to get a spare drive before these old EFRX drive are not available any more. if you are still going around in circles and need direct consultation, we have just started providing one-hour consultations via zoom. You can find out more about them via the link below: It had initially 5 disks of type WD30EZRS. One of them crashed few months ago and I replaced with WD30EZRX which appeared to have same specs.We also measured the power consumption of each Synology model filled with Western Digital Red hard drives through our Eaton Advanced Monitored ePDU, which monitors devices at the outlet level. The eight-bay Synology DS1812+ used 59 watts during active write activity and 55 watts at idle, while the five-bay DS1512+ used 49 watts under load and 44 watts at idle, while the small two-bay DS712+ needed just 31 watts under load and 24 watts at idle.

Condition The obvious question may be then, what’s wrong with the WD Greens and other low power drives that have been performing NAS duty to this point? The answer is really about projected use. The WD Green for instance, while the leading low power drive on the market, wasn’t designed for the 24×7 access requirements that NAS systems require. The WD Red was engineered specifically for this duty, complete with customized NASware firmware which includes critical features like intelligent error recovery controls that prevent drives from dropping off the RAID due to long recovery cycles. The drives also are engineered with "3D Active Balance technology" which tunes the drive to eliminate vibration leading to improved reliability and overall performance. We tested our batch of eight WD Red hard drives in varying configurations ranging from single drive to 2, 5 and 8-bay Synology NAS deployments.In terms of performance, the WD Red did very well not only as a single drive, but increased proportionally as we scaled up the testing in the Synology DiskStations. With link-aggregation we measured read speeds in excess of 200MB/s (8-bay) and write speeds coming in just below 170MB/s (5-bay). Random I/O performance with each model in RAID was good, showing a nice linear increase in speed with each larger RAID array. In both active and idle settings, we found power consumption to be very good, with even the eight-bay DS1812+ filled with Reds measuring under 60 watts under load and 55 watts at idle.

The WD Red comes in 1TB, 2TB and 3TB capacities with 64MB cache, SATA 6Gb/s interface and Intellipower low power spindle. For data migration Western Digital has included a copy of Acronis True Image software. WD offers a three year warranty, dedicated support line and QR code on the drive for mobile access to product documentation and support. Reliability: Desktop drives aren’t typically designed for the demands of an always-on NAS environment. WD Red hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments. Experienced in NAS - WD Red is a reflection of the most extensive NAS partner compatibilitytesting list that is available on the market.* That means when you buy a NAS enclosure, you can trust that WD Red will be the most compatible drive available. Our pride is in our product and our vision is shared with our customers. It’s an interesting decision – WD is expanding their low-power 3.5" hard drive offerings with a second line at the same time Seagate exists the "green" market, claiming low-power drives aren’t really all that beneficial or quite frankly, special. The Western Digital Red family of hard drives is designed for the 1 to 6 bay SOHO NAS space, which is about as specialized as it gets. WD has several features that they’re touting as critical for the NAS user including; NASware specialized firmware, Intellipower low power spindle, robust NAS compatibility list, three year warranty and a dedicated WD Red 24×7 customer support line (1-855-55-WDRED if you need them). If you connect by example 10 SSD, you will be near to load 6G/s * 10 = 60Gb/s = 7.5 GB/s (very theorically, but maybe reach the PCH bus limit ?)

Thank you!

For a long time there was an obsession with ashift=9 vs ashift=12 because of various reasons. This has an impact on a variety of things including space consumption and performance. Using ashift=9 on 4Kn is particularly bad for performance. Several different things have been done over the years to try to make this work correctly. I don't recall what the exact current strategy is, but I believe it tries to optimize correctly.
