WD Blue SA510 2TB M.2 SATA SSD: features, specs and who it suits

The WD Blue SA510 is an internal solid state drive from Western Digital. This version, model WDS200T3B0B, holds 2TB and comes in the M.2 2280 format, a small stick that fits into a motherboard or laptop slot. It suits anyone replacing a slow hard drive or adding storage to an older machine without moving to a newer type of drive.

What SATA III and M.2 mean together

Two separate ideas are packed into the drive's name. M.2 2280 describes the physical shape: a stick about 22 mm wide and 80 mm long, which matches the roughly 3.1-inch length given in the dimensions. SATA III at 6 Gb/s describes how the drive talks to the computer.

This matters because M.2 slots come in different types. Some carry NVMe (PCIe) drives, some carry SATA drives, and some handle both. The SA510 is a SATA drive, so it needs an M.2 slot that supports SATA. Western Digital also lists a 2.5-inch version of the SA510 for machines that use a conventional drive bay, but this page covers the M.2 model.

What up to 560 MB/s means in practice

Western Digital rates read speeds at up to 560 MB/s for the 500GB to 4TB capacities, based on its internal testing, and notes that results vary with the host device, usage and capacity. That figure is close to the ceiling of the SATA III connection, which is typically around 550 to 600 MB/s in real use.

Compared with a mechanical hard drive, that usually means faster start-up, quicker application loading and less waiting when opening large files. It is slower than NVMe drives, which use a faster connection, but it is a straightforward upgrade for systems that can't use NVMe.

Capacity, endurance and power draw

At 2TB, the drive has room for an operating system, a large software library and sizeable media projects. Western Digital notes that 1TB is counted as one trillion bytes, so the capacity your operating system reports will be somewhat lower. That is standard for storage products.

The brand also points to high endurance and low power draw, which can help laptop battery life, and to the absence of moving parts, which means less vibration than a hard drive. Solid state drives are typically silent.

Included software

The listing mentions Acronis True Image for Western Digital, a backup and cyber protection tool, with a five-year licence for a compatible drive. It needs to be downloaded and installed, and must be redeemed within a set period after purchase. Offers like this can change or end, so confirm the current terms on Western Digital's website.

Who it suits

• People upgrading an older laptop or desktop from a hard drive.
• Content creators and editors who want more working space on a SATA-based system.
• Anyone building a secondary drive for projects, games or backups.

What to check before you buy

• Slot type: confirm that your M.2 slot supports SATA drives, not only NVMe. Your motherboard or laptop manual will say.
• Length: 2280 means 80 mm; check that your device has a mounting point for that length.
• Height: thin laptops can limit the space above the slot, though M.2 sticks are very slim.
• Migration: plan how to move your existing data, using cloning software or a fresh install.
• Backups: keep a copy of important files elsewhere, as with any storage device.
