WD Blue SA510 Spec and Price in the United Kingdom

SATA2TB2.5-inch560 MB/s read

Released May 31, 2022

As the only SATA drive among these four Western Digital models, the SA510 caps out at 560/520 MB/s sequential and around 89K/75K random IOPS, limits set by the SATA interface itself rather than the controller. Endurance sits at 700TB written, the lowest figure in the WD Blue/Black lineup, backed by the same 5-year warranty as its NVMe siblings. It suits older systems or budget builds where a motherboard lacks NVMe slots, where raw NVMe speed was never part of the equation.

Tied 87th of 106 models in the SSD catalog on Sequential read — 8 models share this figure. Tied 94th of 106 models in the SSD catalog on Sequential write — 3 models share this figure.

How to choose an SSDFour questions decide almost every SSD purchase — what fits, how big, how fast, and how much it should cost.NVMe or SATAWhich interface your machine takes, how to tell without opening it, and what the speed difference actually buys you.How much SSD capacity you actually needHow to size a drive from what you already use, why leaving headroom matters, and when one bigger drive beats two small ones.M.2 sizes and SSD form factorsWhat 2280, 2242, and 2.5-inch mean, which one your machine takes, and how to check the keying before you buy.What SSD speed numbers actually tell youSequential versus random performance, why the number on the box describes the rarer case, and how to read it without being misled.PCIe generations for SSDsWhat Gen 3, Gen 4, and Gen 5 change, why a newer drive always works in an older slot, and when the extra speed is worth paying for.TLC, QLC, and DRAM-less SSDsWhat the NAND type and the controller's cache change about how a drive behaves, and when either is worth caring about.SSD endurance and warrantiesWhat TBW and DWPD actually promise, how much a normal machine writes, and when endurance is worth paying extra for.How to install an SSDFitting an M.2 or 2.5-inch drive, choosing between cloning and a clean install, and what to check on the first boot.When an SSD price is actually goodWhy price per terabyte beats any discount percentage, and why a good price on one capacity says nothing about the others.

What owners and reviewers say

Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Consistent performance for daily workloads and light creative tasks, with wide compatibility.
  • Fast boots, smooth multitasking and easy cloning.

Commonly criticised

  • The SATA interface caps speed, and sustained heavy writes can dip compared to top-tier SATA models.
