256GB SATA SSD for Laptops and Desktops

The DUCI 256GB 2.5-inch SATA internal SSD uses the SATA 3.0 interface to deliver read speeds up to 500MB/s and write speeds up to 376MB/s. It is built for gaming, work and everyday computing on both laptops and desktop PCs. The drive fits standard 2.5-inch drive bays.

Shock-Resistant Build with Silent Operation

A durable design withstands shocks and drops while power failure protection helps keep data secure. The drive runs silently with a maximum power draw of 2W, making it suited for quiet, energy-efficient systems. Standard SATA data and power connectors enable straightforward installation.

Upgrade from Mechanical Hard Drives

Replacing a traditional hard drive with this SSD removes moving parts, cuts noise and reduces power consumption. The jump is worth it when faster boot times, quicker application launches and improved responsiveness are priorities. Trim, ECC and S.M.A.R.T. support help maintain performance over time.

Questions about this item

What real-world throughput does the SATA 3.0 interface limit this 256 GB drive to?

The SATA 3.0 link caps sequential reads at 500 MB/s and writes at 376 MB/s, so the drive cannot exceed those figures in sustained transfers.

What are the exact dimensions I need to clear in a 2.5-inch bay or caddy?

The drive measures 4.94 in long, 2.76 in wide and 0.28 in high, matching the standard 2.5-inch form factor for laptops and desktops.

Which step do people skip when installing this SSD in a laptop?

Many forget to enable AHCI mode in the BIOS before cloning or installing the OS, which is required for TRIM and full SATA performance.
