However, SSD cells wear out after a limited number of writes. Controllers help mitigate this, allowing for many years of use under normal conditions. [27] HDDs have moving parts prone to mechanical wear, but the storage medium (magnetic platters) does not degrade from read/write cycles. Studies have suggested HDDs may last 9–11 years. [28]
Sold its NAND flash memory and SSD businesses to SK Hynix. Intel has terminated its Optane line of memory. Sold its NAND flash memory and SSD businesses to SK Hynix. Intel has terminated its Optane line of SSDs. No Sold its NAND flash memory and SSD businesses to SK Hynix, so SK Hynix now makes those controllers.
A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts. [4]
The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14] The drive, which uses a controller from Marvell Technology Group, [15] was released using 34 nm NAND Flash and came in capacities of 120 GB and 250 GB. The second product announcement, the SSD 320, is the successor to Intel's earlier X25-M.
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
While traditionally these products have used HDDs, Western Digital has started to offer SSD versions, such as the My Passport SSD, its first portable SSD. [79] Western Digital external hard drives with encryption software (sold under the My Passport brand) have been reported to have severe data protection faults and to be easy to decrypt. [80 ...
Compared to hard disk drives and similar electromechanical disk storage that use moving physical parts to spin a platter or disc, SSDs are typically more compact, quieter, more resistant to physical shock, and have higher input/output rates, lower latency [13] and less power consumption.
As a family of form factors, it defines specifications for the mechanical dimensions and electrical interfaces devices should have, to ensure compatibility between disparate hardware manufacturers. The standard is meant to replace the U.2 form factors for drives used in data centers. [1] EDSFF provides a pure NVMe over PCIe interface. One ...
