8/29/2023 0 Comments Ssd external hard driveSamsung’s 8TB 870 QVO remains the absolute sweet spot and the benchmark for large capacity SSD at less than half the price of the Teamgroup QX ( $799 at Newegg). Despite its target audience, it remains expensive at just over $2,800 or around $190 per TB. It is, according to its manufacturer, the largest SATA SSD with a three year warranty and a 2.56PBW warranty. Note that this is a SAS drive which means that it will be difficult to shove one of these in a NAS drive or in an external enclosure to turn it into a portable SSD (or indeed the largest portable SSD ever).Įnter the Teamgroup QX, a 15.36TB SSD with a SATA interface that makes it compatible with almost all desktops and laptops that have a free 2.5-inch bay. Its 9400 Pro matches both Intel and Samsung for capacity and warranty and comes in at a cool $3,645. The third player with a large capacity SSD is Micron. Intel (now Solidigm) has an SSD - the D5-P5316 - in the same form factor (U.2) but with a faster read/write speed and a much lower price tag ( as low as $3,088 ) which is less than $100 per TB. It is an expensive part at $4,375 (or around $140 per TB) even if it comes with a five year warranty and a 1-drive-written per day capacity. Samsung’s PM1643a, a three-year old enterprise solid state drive with a SAS interface was the first 2.5-inch SSD with a capacity of 30.72TB. There are three SSD that compete for the crown of biggest SSD ever at 30.72TB. Removable Laptop SSDs take the shape of 2.5-inch slabs or M.2 bars. This is essentially disassembling the external HDD and reusing the hard drive inside either in an array or in a desktop computer. This price difference, then, gave rise to a popular technique known as shucking. The basic Elements/Easystore desktop HDD retails for $450 while the souped up My Book costs $600 prices do fluctuate though so expect price drops around Black Friday and Cyber Monday. Note that these drives tend to use CMR rather than the controversial SMR technology.Įxternal hard disk drives of similar capacities sell for a bit more, a far cry from a few years ago when they were selling for much less, which is paradoxical given that they cost more to build. Western Digital has seeded multiple 22TB models in the wider retail market: the data center version (HC570) ($449), the purple surveillance hard drive ($458.18), the NAS Red version ($509) and the enterprise model ($549) all have 512MB cache and target the prosumer up to enterprise level looking for the largest internal HDDs. It has a 256MB cache and a 7200RPM rotational speed, which means that it is likely to be one of the fastest HDD around. It features 10 platters and uses CMR (conventional magnetic recording) rather than the controversial SMR to reach that capacity. In April 2012, Seagate also unveiled a 22TB version of its Iron Wolf Pro HDD (ST22000NT001) for a mere $363 ( at Amazon). It is available with SATA or SAS interfaces and comes with 5-year warranty, 256MB cache and a 7200RPM rotational speed. The Seagate Exos X22 is not listed on Seagate's website (although there's a product support page for it) but widely available ( online retailer Wiredzone sells it for $406). Toshiba has a 20TB CMR Hard disk drive but no plans for a 22TB one yet. 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).
