About this deal

And here is how the WD Red Pro 22TB sounds when the HDD is being HEAVILY accessed. using a benchmarking tool and extensive random 4K IOPS in read/write testing. Note, the higher the frequency of files, the noisier it will be, as the actuator inside will be working considerably hardware to allocate the small size/high frequency of data to the platters):

These last tests are important as not only is the WD Red Pro 22TB HDD designed for NAS use, but also at the time of writing neither brand lists this hard drive as compatible. There is more to this though that I will touch on later. Specifically designed for use in enterprise-grade storage systems and data centers, WD Gold HDDs are broadly compatible with major enterprise operating systems. The uncompetitive (only three manufacturers globally) HDD market is doing what the GPU market is. Old capacities are keeping their prices years after release and newer higher capacities are pushing prices ever higher. Hard disk drives are cheap and offer plenty of capacity but they are bound to disappear in a not-so-distant future. Right now, the biggest portable hard disk drive has a capacity of 5TB; it uses a special drive that is slightly bigger than a standard laptop HDD which has a width of 2.5-inch and a height of 7mm.The Seagate 60TB SSD that was launched in 2016. It was a prototype but we don't know whether it was sold. I approached Seagate in May 2023 to find out what happened to it.

The WD Gold 22TB did not disappoint at the SMB level, posting solid numbers throughout. Professional offices like architects and content creators will find that these massive hard drives will bring a lot of flexibility, performance, and room for growth when combining them with a NAS solution like the Synology DS1821+. For standard deviation, the WD Gold recorded 611.48ms read and 333.9ms write in SMB, and 51.12ms read and 165.22ms write in iSCSI.It is important to be aware of the drive’s form factor, with 3.5” being the most common for the best HDDs (this is the only type we cover). If you need 2.5”, your options are more limited, especially for capacity. Otherwise, your computer case’s ability to house a certain number of 3.5” drives might be your primary limitation. WD states that OptiNAND drives can secure more than 100MB of write cache data in the event of an unplanned power loss, a 50X improvement over standard drives that can flush about 2MB. Hybrid Drive media is not new, but whereas older generation hybrid drives were more parallel in architecture, this is far more intertwined. It also brings enhancements to the firmware algorithm and system-on-a-chip (SoC). Once again, to be clear, OptiNAND and its iNAND isn’t flash cache (such as the 512MB this drive also features). Rather, it’s a portion of flash memory used to store metadata–or data about existing data–so they can be managed more efficiently. WD’s unique OptiNAND-enabled ArmorCache technology combines the performance of write cache enabled mode with the data protection of write cache disabled mode without having to compromise by choosing between the two. The sides of the WD Red Pro 22TB are quite standard and exactly what you might expect, completely sealed from all sides and feature the usual screw holes. The interface of the drive is a SATA data+power connector that does manage to give you a little perspective about the height of this drive and the density of those contained platters in this 2.61cm high media casing (it pretty much maximizes the full conventionally available space a 3.5″ can suitably occupy in any NAS server bay right now. This SATA port allows the drive to provide a reported maximum performance of 265MB/s Sequential Read (the tiniest pinch lower than the 272MB/s of the 18TB WD Red Pro) which is still remarkably impressive, almost halfway saturating the bandwidth of SATA and closing in on the speeds of early SSD technology in the late 00’s and early teens. Moving on to the max latency, the WD Gold hit 2,453.2ms read and 3,779.2ms write in SMB, while the reaching 1,461.1ms read and 846.9ms write in iSCSI.

Our next test shifts focus from a pure 8K sequential 100% read/write scenario to a mixed 8K 70/30 workload, which will demonstrate how performance scales in a setting from 2T/2Q up to 16T/16Q. Our first throughput test measures 4K random performance. Here, the WD Gold 22TB posted 107,303 IOPS in reads and 4,730 IOPS write (SMB). In comparison, the 12TB WD Ultrastar was able to reach 107,884 IOPS read and 5,600 IOPS write. Solidigm and its two 30.72TB SSDs: The D5-P5430 (coming later this year) and the D5- P5316 , as well as the 61TB D5-P5336 Turn off or choose between three modes of brightness (off, default, and bright) to easily adjust the LED lights.

Thank you!

WD Gold drives are available in capacities up to 24TB utilizing the OptiNAND technology's capacity-enabling feature. Moving on to max latency numbers, the 22TB WD Gold had a range of 10ms to 40.2ms while the 12TB WD Ultrastar showed 10.01ms through 87.95ms.

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.Available with a SATA or SAS interface, it offers an unlimited drive write per day for five years (the length of the warranty) thanks partly to the use of SLC technology (which explains the price as well). A cheaper version of the Exadrive, the EDNLT064, is also available and is the second largest solid state drive on the market with a capacity of 64TB but swaps TLC for QLC. The eventual technological road you can go down with using Multi-Actuator technology easily allows you to make R/W of 1 TB reasonable when you can easily pump up R/W speeds into the GB range. For performance, we installed eight of these drives in our 36-bay Supermicro Storage SuperServer (configured in SMB) and compared them alongside a set of WD’s 12TB Ultrastar HDDsfor reference. We saw some pretty great throughput across our benchmarking, including 107,303 IOPS in reads and 4,730 IOPS write in random 4K, 109,454 IOPS read, and 105,577 IOPS during our 100% read and write activity at 8K sequential workload, a range of 14,333 IOPS to 26,882 IOPS for our mixed 8K 70/30 workload, and 2.31GB/s in both read and writes. Nevertheless, you can still push through this warning and proceed to testing the performance of the WD Red Pro 22TB HDD from within the Synology Storage Manager. Here was the results. The company's publicly available roadmap indicates that Seagate intends to deliver 50+ TB hard drives in calendar 2026, so the HDD maker has plenty of time to polish off its 50TB media for mass production. 22TB and 24TB HDDs Due Shortly
