An M.2 SSD (formerly known as Next Generation Form Factor or NGFF) is a type of solid-state drive that is designed to be used in smaller devices like laptops, tablets, and ultrabooks.

These include having a PCIe 4.0 M.2 NVMe interface (key M), ... 2242, 2260, 2280, 22110 SSD form factors are compatible, and the SSD's thickness must not exceed 11.25mm.

These SSDs commonly come in the 2.5-inch form factor (the size of a laptop’s hard drive). The latest SATA SSDs use the SATA revision 3.0 interface, which has a maximum transfer speed of 600MB/s.

KIOXIA’s breakthrough Enterprise and Datacenter SSD Form Factor (EDSFF), also known as E3, is designed to maximize system density, efficiency and simplicity.

The new SSD is built with 16 of Samsung’s 512-gigabyte (GB) NAND packages, each stacked in 16 layers of 256 gigabit (Gb) 3-bit V-NAND chips, achieving an 8TB density in an ultra-small footprint ...
