What it is
A Samsung 128 GB 2.5-inch SATA III SSD with MLC (Multi-Level Cell) flash memory is a type of internal solid-state drive (SSD) designed for laptops and desktops:
Form factor: 2.5-inch standard drive (fits in typical laptop/desktop SATA bays).
Interface: SATA III (6 GB/s) — backward compatible with SATA II/I.
Capacity: ~128 GB of storage.
Performance
Sequential read: ~500–520 MB/s
Sequential write: ~300–500 MB/s
MLC NAND Flash
MLC (Multi-Level Cell) stores 2 bits per cell, offering higher endurance and longevity compared with older TLC or QLC designs (especially in older Samsung SSD generations).
Works with any system that supports 2.5″ SATA drives (laptops, desktops, small form factor PCs).
Ideal for OS installation, data storage, and general application use.
