Samsung PM981 512GB NVMe
A fast NVMe M.2 SSD for laptops and desktops, delivering sequential read speeds up to 3000 MB/s for quick boot times and file transfers. The 512GB capacity works well for OS and applications, while the single-sided PCB design fits easily into thin laptops and compact systems. Built on TLC NAND with DRAM cache for consistent performance, it's a solid upgrade for anyone looking to speed up an older machine.

Drive Type
SSD
Interface
The physical connection to your computer, console, or camera. NVMe is typically fastest, but SATA, USB, and SD speeds vary a lot between products, check the Read Speed row too.
NVMe
Form Factor
The drive's physical size and shape. M.2 is a slim stick for modern SSDs, 2.5″ and 3.5″ are older cased formats.
M.2 2280
Read Speed
How fast data can be read from the drive. Higher is better, especially for boot times and load screens.
3.0 GB/s
Write Speed
How fast data can be written to the drive. Matters most for copying large files, recording video, or heavy multitasking.

PCIe Gen
Each PCIe generation roughly doubles the drive's top speed. Your motherboard needs to support it too.
Gen 3
NAND Type
TLC is the mainstream flash type with a solid balance of speed and endurance. QLC costs less per gigabyte but slows more under heavy writes.
TLC
DRAM Cache
A DRAM cache gives steadier performance under heavy or random workloads. Drives without one are usually fine for everyday use.
Yes
Sided
Whether the flash chips are mounted on one side of the circuit board or both. Single-sided drives fit in more laptops and handhelds with tight internal clearance, and their heatsinks are an easier fit in the PS5's expansion bay too.
