Kingston KC600 Spec and Price in the United Kingdom

SATA2TB2.5-inch550 MB/s read

Released October 22, 2019

As a 2.5-inch SATA drive, the KC600 tops out at 550/520 MB/s — the ceiling the SATA III interface imposes regardless of controller — but its Silicon Motion SM2259 controller, DRAM cache, and 1200TB TBW rating exceed what typical SATA drives in its class carry. That endurance figure and 5-year warranty read closer to a workstation-grade drive than a basic boot-drive upgrade, useful for anyone replacing an aging HDD or SATA SSD in a system that can't take NVMe. It fits users prioritizing drive lifespan and reliability over the raw throughput only PCIe NVMe can offer.

Tied 96th of 106 models in the SSD catalog on Sequential read — 4 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 14, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers measured sequential read and write speeds at essentially the SATA ceiling.
  • Its quoted 600TBW endurance for the 1TB model is a significant step up from many competing SATA drives.
  • It supports hardware encryption, and the optional bundle adds mounting hardware, cables, and a USB enclosure.

Commonly criticised

  • It is not as fast as NVMe drives and lagged behind a rival SATA drive in PCMark 10 storage traces.
  • It is not the cheapest SATA option at its capacity.
