WD 22TB Elements Desktop External Hard Drive - USB 3.0

Product Information

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. One common question is, " Is an SSD a hard drive?" While many might call an SSD (Solid State Drive) a hard drive out of habit, an SSD is quite different from a traditional HDD (Hard Disk Drive) with spinning platters in terms of design and performance. Without going too deep into the ' SSD vs HDD' debate, in essense, SSDs offer faster data access and are more durable due to the absence of moving parts, but typically have lower maximum storage capacities than HDDs and are more expensive. For instance, finding an SSD over 8TB can be challenging, while HDDs, while slower, can have capacities of 20TB or even more. Fates_Demise said:hdd companies are cutting production from lower demand which will keep prices up. 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 Gold drives are available in capacities up to 24TB utilizing the OptiNAND technology's capacity-enabling feature. It boasts exceptional read and write speeds; we recorded speeds of 286.8MB/s and 279.3MBps respectively in the 20TB iteration, based on testing via CrystalDiskMark, although This is roughly 10% faster than the previous 18TB drive and is sure to be beaten again by the newly launched 22TB iteration of the zippy HDD.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. Specifically designed for use in enterprise-grade storage systems and data centers, WD Gold HDDs are broadly compatible with major enterprise operating systems. Testing the WD Red Pro 22TB is going to be performed across multiple methods, but still rather unconventional. This drive is designed for deployment in 8+ Bay servers and higher and although I have several NAS in the studio that could accommodate this frequency of drives, I do not have multiple WD Red Pro 22TB units. Therefore the testing I have conducted are all examples of single-drive performance. These will include several PC testing sessions using popular and recommended storage testing applications and two NAS tests involving Synology and QNAP. 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. With up to 2.5M hours MTBF 3, WD Gold hard drives deliver enhanced levels of dependability and durability.

We also test power consumption and temperature. Power consumption will vary with drive performance, RPM, and more, and it’s important to look at four different cases: maximum power draw, average power draw, idle power draw, and workload efficiency. Power usage can add up with multiple drives. Temperature is also an important metric for hard drives, as overheating is a common cause of failure, particularly during sustained workloads. 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. Overall, the WD Gold 22TB HDDs aren’t trying to break a ton of new ground, they don’t really need to. Data availability is the name of the game for HDDs, but the 22TB Golds do offer a good performance profile as well. The WD Gold 22TB HDDs should find plenty of practicality for any application where data density and availability are the primary factors. The hardware architecture of the WD Red Pro 22TB NAS hard drive is a combination of everything that we have seen in previous revisions of this long-running drive media series, combined with a new method of drive and data metadata management. This drive errs away from the energy-assisted magnetic recording of the Ultrastar 22TB released earlier in 2022, instead managing to provide this herculean 20 terabytes of storage via traditional conventional magnetic recording. It does this with data being split across TEN 2.2TB platters internally, spinning 7200RPM and with 512MB of onboard cache for buffering. The Pro moniker in the model ID is based on portfolio separation in the WD Red series (featuring WD Red, WD Red Plus and WD Red Pro) with this new 22TB NAS HDD being heavily aimed at a larger scale business use. This architecture (along with the noise and vibration protection being handled by 3D Active Balance and geared with the NASWare 3.0 firmware) allows a 300TB per year workload rating, (data center class is 550TB), a 1 million hours MTBF rating and the brand including a 5-year warranty with the drive. Below is a greater breakdown of the WD Red Pro 22TB specifications: Model Number While Seagate's product roadmap for the rest of the year looks extremely promising, the company's quarter ended on December 30, 2022, is nothing but depressing as the company reported its first loss in years.The Seagate Skyhawk AI HDD is designed with “AI'' firmware to improve the drive’s ability to handle recording, video analysis, and GPU analytics workloads. This includes up to 64 HD video streams and 32 AI streams with zero dropped frames. This is combined with a robust warranty, including a high workload rate and Seagate’s three-year data recovery service.
