TRIM is an ATA command (Advanced Technology Attachment Command) that allows an OS to inform SSD about the blocks of data no longer in use. The SSD then deletes such blocks of data to make a way for newer blocks of data. TRIM is basically used for enhancing the performance and life span of the SSD.
Write amplification goes down and SSD speed goes up when data compression and deduplication eliminates more redundant data. This writes data at a rate of one bit per cell instead of the designed number of bits per cell (normally two bits per cell or three bits per cell) to speed up reads and writes.
Intel Rapid Storage Technology. Intel Rapid Storage Technology (RST) is a driver SATA AHCI and a firmware-based RAID solution built into a wide range of Intel chipsets. Currently also is installed as a driver for Intel Optane temporary storage units. It contains two operation modes that follow two Intel specific modes rather than the SATA standard.
Versions since Mac OS X 10.6.8 (Snow Leopard) support TRIM but only when used with an Apple-purchased SSD. [195] TRIM is not automatically enabled for third-party drives, although it can be enabled by using third-party utilities such as Trim Enabler.
The X25-M SSD. The Intel X25-M was a line of Serial ATA interface solid-state drives (or SSDs) developed by Intel for personal computers, announced in late 2008. The SSD was a multi-level-cell solid-state drive available in a 2.5" form factor, came in 80 GB and 160 GB capacities and utilized NAND flash memory on a 50 nm process.
Wear leveling. Wear leveling (also written as wear levelling) is a technique [1] for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid-state drives (SSDs) and USB flash drives, and phase-change memory. There are several wear leveling mechanisms that provide varying levels ...
IOPS. Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to ...
