But unlike the IronWolf Pro, the 20TB design shows no improvements in operational power demands over the 18TB models, and the SAS models use an extra 0.4W over the SATA versions at idle.

PiranhaTech said:This is making me wonder if motherboards will start coming with SAS ports instead. There's no news for SATA 4. Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. U.2 also allows you to install multiple SSD drives on workstation mobo. Which of course you can't do with consumer M.2 mobo, because you would end up with a giant mobo.

That said, as a platter-based hard drive, it's best equipped to store a game library; you're better off loading the games you're currently playing from an SSD. If you conservatively figure an average game size of 100GB, the 4TB version tested here can hold about 40 titles, serving as the stylish main repository of your collection for years to come, and for a much more modest outlay than you'd spend on an SSD of similar capacity. Who It's For Another Seagate drive with ten 2TB platters in the classic 3.5-inch form factor to sit alongside the new IronWolf Pro 20TB. The only significant difference on the outside is that the EXOS comes in a SAS flavor in addition to a conventional SATA variety model.And for those seeking recommendations, we've curated a list of the best NAS hard drives suitable for personal, home office, and small business use, utilize our custom price comparison tools to ensure you're obtaining value for money. Triple-Level Cell (TLC): TLC stores 3-bits per cell for up to eight levels of charge. Commonly used for consumer grade products, TLC has a lower performance, reliability and endurance to the previous two. However a cheaper price and higher memory density make up for the drop in performance. The 3D variant can reach up to 3K P/E cycles.

The SATA EXOS comes either with Standard or SED FastFormat, and the SAS model adds SED-FIPS to those options. I feel like I'm in the dark ages when installing or switching out an M.2 SSD that requires a screwdriver. The company’s current largest drive is an 18TB model, which lags behind the 20TB drives currently on offer from Western Digital and Seagate.Seagate’s Exos X20 drive is very similar to its IronWolf Pro line. Its higher workload rate and MTBF specification suggest it is more for enterprise use, however. It doesn’t reach 22TB like the WD Gold, and also has less cache. That aside, the performance and warranty are both good, so this is a choice that comes down to pricing. According to the makers, the Seagate EXOS 20TB is targeted at those with cloud data centres, massive scale-out data centre applications, bulk storage and enterprise NAS systems. Where the IronWolf Pro was meant for commercial and Enterprise NAS to support the needs of Creative Pro and Medium-to-Large businesses. U.2 also allows you to install multiple SSD drives on workstation mobo. Which of course you can't do with consumer M.2 mobo, because you would end up with a giant mobo.U.3 to the rescue, replace the SATA ports on the right edge of the MoBo with U.3. U.2 is SATA 4.0 really, and it is successful on workstations and servers because you can change out a drive in 2 seconds. But apparently they think consumers prefer diving into their case with a screwdriver like an idiot instead of simply plugging something in and out.

The IronWolf Pro has larger caches for many of its models with the same storage capacity, including 20TB, and also a corresponding workload rating increase, from 300 to 550 TB/year. The two biggest hard disk drive vendors have released 22TB hard drives with Western Digital unveiling a 26TB model in 2022 (although you won't be able to buy it as it is a data center only product). Toshiba has a 20TB CMR Hard disk drive but no plans for a 22TB one yet. It is rumoured that by the end of the year, Toshiba will reveal a 10-platter 26TB drive based on microwave-assisted switching (MAS-MAMR) technology, to be then followed by an 11-platter 30TB model next year. Solid-state drives (SSDs) have fewer moving parts than traditional hard drives, and they offer the speediest access to your data. Unlike a conventional disk-based hard drive, which stores data on a spinning platter or platters accessed by a moving magnetic head, an SSD uses a collection of flash cells—similar to the ones that make up a computer's RAM—to save data. Most of the damage to the NAND cells occurs during random writes in an SSD, and relatively minor wear happens when reading.CrystalDiskMark: 289.07MBps (read); 295.75MBps (write) Atto: 281.32MBps (read, 256MB);275.27MBps (write, 256MB) Obviously, the ultimate goal is every actuator arm being fully independent, that would be "AWESOME". Additionally, the number of bits a cell contains serves as one of the primary ways to classify NAND Flash: Where the IronWolf Pro 20TB offered an MTBF (Mean Time Between Failure) is 1.2 million hours, and the yearly workload is 300TB. The EXOS 20TB exceeds those levels with a 2.5-million-hour MTBF rating and 550TB annual workload. This hard drive has very similar specifications and pricing as the Seagate IronWolf Pro, which has the advantage of a slightly higher maximum sustained write speed and Seagate’s three-year rescue plan. The Red Pro has a larger DRAM cache, though, and its OptiNAND technology gave better 4KB results, so its better for workloads that have small I/O.
