The following were the largest NAND flash memory manufacturers, as of the second quarter of 2023. [26] Samsung Electronics – 31.4%; Kioxia – 20.6%; Western Digital Corporation – 12.6%; SK Hynix – 18.5%; Micron Technology – 12.3%
This is true for all versions of Mac OS X from 10.7 through macOS 10.12.x. TRIM is supported for RAID (0,1,4,5 & 10) volumes when using the third-party SoftRAID® application, including TRIM support with non-Apple SSD devices. (Note: TRIM for non-Apple SSD devices must be specifically enabled using the terminal command "sudo trimforce enable".)
SanDisk Fusion ioMemory PX600-5200: 5.2TB FH/HL PCI-E SSD. NexGen n5 in 2012, renamed ioControl hybrid storage ION Accelerator. Fusion-io, Inc. was a computer hardware and software systems company (acquired by SanDisk Corporation in 2014) based in Cottonwood Heights, Utah, that designed and manufactured products using flash memory technology.
The Flash Modules were designed from the ground up by Texas Memory Systems using proprietary form-factors, physical connectivity, hard-decision ECC algorithm, and flash translation layer (FTL) contained completely inside the SSD. The flash controllers used a hardware only data path that enabled lower latency than any other commodity controllers ...
As SSD technology continues to improve, they are increasingly used in ultra-mobile PCs and lightweight laptop systems. The first flash-memory SSD based PC to become available was the Sony Vaio UX90, announced for pre-order on 27 June 2006 and began shipping in Japan on 3 July 2006 with a 16 GB flash memory hard drive.

When the system or device needs to read data from or write data to the flash memory, it will communicate with the flash memory controller. Simpler devices like SD cards and USB flash drives typically have a small number of flash memory die connected simultaneously. Operations are limited to the speed of the individual flash memory die.
The number of program/erase (PE) cycles is limited. Because of these constraints SSD controllers write data to NAND flash memory in another order than the logical block order. This implies that the SSD controller must maintain a mapping table from host (logical) to NAND (physical) addresses. This mapping is usually called the L2P table.
In practice, flash file systems are used only for Memory Technology Devices (MTDs), which are embedded flash memories that do not have a controller. Removable flash memory cards and USB flash drives have built-in controllers to manage MTD with dedicated algorithms, [2] [3] like wear leveling, bad block recovery, power loss recovery, garbage ...
