WD Blue SA510 1 TB SATA SSD

The WD Blue SA510 is a 2.5 inch internal solid state drive with a 1 TB capacity. It uses triple level cell NAND and a SATA 6 Gbps interface to boost system responsiveness. The drive suits desktops and laptops that need reliable storage for everyday workloads.

SATA 6 Gbps interface limits

SATA 6 Gbps caps sequential throughput at the bus maximum, so sustained transfers cannot exceed that ceiling. Random read performance reaches up to 8200 IOPS for small block access. The interface is backward compatible with older SATA ports at reduced speeds.

2.5 inch form factor and build

The 2.5 inch form factor fits standard drive bays and caddies in most PCs and laptops. Physical dimensions are 10 mm height, 8 mm width and 4 mm depth with a weight of 2 grams. The drive has no moving parts, so it resists shock and runs silently in daily use.

Questions about this item

Should I pick the 1 TB capacity or is a smaller version available?

The only capacity listed for this WD Blue SA510 is 1 TB; no smaller versions appear in the specifications.

What does the 8,200 IOPS random read figure mean once the drive is installed?

It shows how quickly the SSD can fetch many small files at once, so operating-system boots and application launches feel snappy.

The drive uses SATA — what does that cap in practice?

SATA 6 Gbps sets the maximum interface bandwidth, so the drive cannot transfer data faster than that link allows.
