About this deal

PiranhaTech said:This is making me wonder if motherboards will start coming with SAS ports instead. There's no news for SATA 4.

An Enterprise-class 20TB NAS drive

And while disk drive capacities are increasing, they can't match the exponential growth seen in competing media. The largest SSD right now is a 100TB model from Nimbus Data, while a prototype of a 580TB tape was unveiled only a few days ago.

For those that use SAS to connect arrays to multiple servers for fail-over functionality, this might be another reason for going with the EXOS, as it doubles the potential pathways from one to two on each drive. A collection of spinning drives configured with a RAID level designed for faster data access can approximate the speeds of a basic SSD, while you should consider a drive with support for RAID levels 1, 5, or 10 if you're storing really important data that you can't afford to lose. Hit the link above for an explanation of the traits and strengths of each RAID level. Some require you to sacrifice raw capacity for data redundancy, so you'll want to pay attention to the nuances of each level. The most common use for hard drives, though, is simple file transfers. Our DiskBench test estimates transfer performance with a real-world workload that is useful for calculating how long a transfer could take. Hard drives have consistent performance and will hit their maximum sustained speed at QD1 with large enough I/O, which is illustrated in our ATTO benchmark results. This is particularly useful for showing differences in technology and capacity as drives get bigger and faster.The SATA EXOS comes either with Standard or SED FastFormat, and the SAS model adds SED-FIPS to those options.

My first reaction: Is it really 20 TB of uncompressed data? How much of that is reserved for overhead? These are the first 2 questions that should be answered about any hard drive before you even know if will fit in your case. Most of the damage to the NAND cells occurs during random writes in an SSD, and relatively minor wear happens when reading. The EXOS drive beats the IronWolf Pro with a workload limit of 550TB, a significant improvement over the 300TB of its brother mechanism. These are the same workload limits as the Western Digital UltraStar DC HC560 20TB and WD Gold 20TB. Additionally, the number of bits a cell contains serves as one of the primary ways to classify NAND Flash: That's why you no longer see people experimenting by putting SSD in RAID 4 to get ridiculous speeds, like people did with SATA SSD. You simply can't do that with M.2 SSD, there's no mobo that have 6+ M.2 slots, but there's plenty of workstation solutions with many U.2 slots.The latest Windows 11 update won't install for some users, and tanks gaming performance even if it does Max Payne 1 & 2 Remake in the “production readiness stage” while fans will have to wait longer for Control 2 Probably won't see U.3 on consumer either. Maybe it will make it into Threadripper and Sapphire Rapids boards, at least in the OEM space. Call of Duty's new stupid launcher is a data management nightmare, and it may get worse with Modern Warfare 3

Another difference is that the EXOS 20TB comes in both SATA and SAS connections, whereas the IronWolf Pro is exclusively SATA. Western Digital is planning to split its SSD memory and hard drive operations into two new businesses You'll only see the speed benefits of Thunderbolt, however, if you have a drive that's SSD-based, or a multi-drive, platter-based desktop DAS that is set up in a RAID array. For ordinary external hard drives, Thunderbolt is very much the exception, not the rule. It tends to show up mainly in products geared toward the Mac market. 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.Say, what's "UltraStar" and what happened to their Gold series? UltraStar sounds like it was inherited from IBM - did WDC buy them? You can build your own Starfield space stations thanks to this modder who found the code 'already in the game' 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.
