GUDGA GS-256 2.5" SATA 256GB SSD

The GUDGA GS-256 is a 2.5 inch SATA III internal solid-state drive built with 3D TLC NAND flash. It targets users upgrading a laptop or desktop that only accepts the 2.5 inch form factor and a SATA connection. The 256GB capacity provides space for the operating system and core applications.

Thermals noise and power draw

The drive operates between 0°C and 70°C and can be stored from -20°C to 75°C. It runs on 5V power with no moving parts, so it produces no audible noise during operation. Sequential reads reach 550MB/s and writes reach 500MB/s while drawing minimal power. Endurance is rated at 150TB written and 1,000,000 hours MTBF.

Upgrade from a mechanical hard drive

Replacing a 2.5 inch hard drive with this SSD cuts boot time and application load time dramatically. The 7mm height fits most laptop bays and desktop trays without adapters. The jump is worth it when the system feels sluggish on a spinning disk and the motherboard lacks an M.2 slot for newer protocols.

Questions about this item

How do I install the 2.5 inch GS-256 SATA SSD in a laptop, and what step is often missed?

Mount the 7 mm drive in the 2.5 inch bay, connect the SATA data and power cables, then initialise and format the 256 GB volume in the operating system — the formatting step is the one people forget.

What maintenance or replacement will the GS-256 256 GB SATA SSD need over its life?

The 3D TLC NAND is rated for 150 TBW and 1,000,000 hours MTBF; no scheduled maintenance is required, but the drive should be replaced once the 150 TBW endurance limit is reached.

What performance limit appears first on the GS-256 256 GB SATA SSD during sustained heavy writes?

Sequential write speed peaks at 500 MB/s and the 150 TBW endurance budget is the first hard limit reached under continuous heavy write workloads.
