2TB SATA internal SSD with enclosure and toolkit

This bundle combines a 2TB 2.5" SATA III solid-state drive, a USB 2.0 drive enclosure and a five-piece mini toolkit. It is aimed at consumers who want to upgrade a laptop or desktop and then reuse the original drive as external storage. The drive uses 3D NAND flash and a Silicon Motion SM2246EN controller with no DRAM cache, relying on host memory buffer support instead.

Sustained write behaviour with real-time redundancy

The controller allocates 128GB of the 2048GB total flash to real-time data redundancy and error correction, leaving 1920GB usable and 1860GiB formatted. Native command queuing handles up to 32 commands, and the drive is qualified for RAID 0, 1, 10, 0+1 and SPAN configurations, so performance remains consistent during extended multi-drive workloads rather than only in short bursts.

Check SATA port version and USB 2.0 speed limit

Before ordering, verify that your system has a free 2.5" SATA bay and a SATA 6Gb/s, 3Gb/s or 1.5Gb/s port to match the drive's backward-compatible interface. The included enclosure connects via USB 2.0 mini-B, so external transfers will be limited to USB 2.0 speeds regardless of the drive's internal SATA capability.

Questions about this item

How much power does the 2TB SATA SSD draw during all-day operation?

The drive has no DRAM cache and uses Host Memory Buffer, keeping power draw low for a 2.5-inch SATA SSD.

What else must I own to install this 2.5-inch SATA drive internally?

A free 2.5-inch drive bay, a SATA data cable and a SATA power connector from the power supply.

Will this SATA 6Gb/s SSD work in an older laptop that only supports SATA 3Gb/s?

Yes, the drive supports SATA 6Gb/s, 3Gb/s and 1.5Gb/s, so it will run at the slower speed automatically.
