GS Series 4TB SATA SSD

The GUDGA GS-4TB is a 2.5 inch internal solid-state drive built for consumer desktops and laptops. It uses 3D TLC NAND flash and connects through the SATA III interface. The drive offers 4TB of storage for operating systems, applications and large file libraries.

SATA III 6Gbps interface

This drive communicates over the SATA III protocol with a 6Gbps link speed. Maximum sequential read reaches 550MB/s and maximum sequential write reaches 500MB/s. Endurance is rated at 2400TB written and MTBF at 1000000 hours.

7mm z-height installation

The drive measures 7.00mm in height so it fits standard 2.5 inch bays in most laptops and desktops. No heatsink is included and the unit draws power from the SATA 5V rail. Operating temperature range is 0°C to 70°C.

Questions about this item

How do the 550MB/s read and 500MB/s write speeds translate to everyday use?

The drive delivers up to 550MB/s sequential read and 500MB/s sequential write over SATA III, so operating-system boots, application launches and large file copies run at the interface limit.

What does the SATA III 6Gbps interface cap in practice?

SATA III tops out at 6Gbps, so the drive cannot exceed roughly 550MB/s read and 500MB/s write regardless of the NAND speed.

Will the 7.00mm height fit my laptop drive bay?

The drive measures 7.00mm high, 69.85mm wide and 100.00mm deep, matching the standard 2.5-inch 7mm bay used in most laptops and desktops.
