64-Layer 3D TLC SATA 6 Gbit/s M.2/2.5" Silicon Motion SM2259 550/500 75/90 August 2017 Endurance: 144 TB to 288 TB, Power Active Average: 4.5W [86] DC S4500
They phased out around 2015 to replace with the newer M.2 format which is way faster in a traditional 2.5" SATA SSD as it uses the PCI Express standard. A solid-state drive ( SSD ) is a type of solid-state storage device that uses integrated circuits to store data persistently .
In 2013, Samsung introduced V-NAND (Vertical NAND, also known as 3D NAND) with triple-level cells, which had a memory capacity of 128 Gbit. [27] They expanded their TLC V-NAND technology to 256 Gbit memory in 2015, [24] and 512 Gbit in 2017. [28] Enterprise TLC (eTLC) is a more expensive variant of TLC that is optimized for commercial use.
In July 2016, Samsung announced the 4 TB [clarification needed] Samsung 850 EVO which utilizes their 256 Gbit 48-layer TLC 3D V-NAND. [183] In August 2016, Samsung announced a 32 TB 2.5-inch SAS SSD based on their 512 Gbit 64-layer TLC 3D V-NAND. Further, Samsung expects to unveil SSDs with up to 100 TB of storage by 2020. [184]
Historically, most SSDs used buses such as SATA, SAS, or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate for SSDs, which ...
On 7 July 2016, Samsung announced its first UFS cards, in 32, 64, 128, and 256 GB storage capacities. [22] The cards were based on the UFS 1.0 Card Extension Standard. The 256 GB version was reported to offer sequential read performance up to 530 MB/s and sequential write performance up to 170 MB/s and random performance of 40,000 read IOPS and ...
