SSD Storage: The Upgrade Guide.

An SSD is the single biggest speed difference you’ll feel in a computer. This guide explains SSD vs hard drive, the sizes (256GB to 2TB), SATA vs NVMe/M.2, what to avoid, and how much storage you actually need — so you buy the right machine the first time.

Why an SSD changes everything.

A solid-state drive (SSD) has no moving parts, so it reads and writes data many times faster than an old mechanical hard drive (HDD). In real terms: your computer boots in seconds, apps open instantly, and files copy in a fraction of the time. It’s the upgrade people notice most — far more than a faster processor for everyday use. That’s why every laptop and desktop we sell comes with an SSD as standard; we never ship a machine with a slow hard drive as its main drive. This guide helps you choose the right size and type, and avoid the common mistakes.

SSD vs HDD

SSD vs hard drive — no contest.

  SSD Hard Drive (HDD)
Boot time ~10 seconds 1–2 minutes
Durability No moving parts — shock-resistant Spinning disk — fragile
Noise/heat Silent, cool Audible, warmer
Everyday feel Instant & responsive Sluggish, especially multitasking

For a deeper comparison see SSD vs HDD. The short version: never buy a computer with an HDD as its primary drive in 2026.

HOW MUCH DO YOU NEED

SSD sizes, explained.

From 256GB to 2TB — match the size to how you use your computer.

256GB

Fine for browsing, email, Office and cloud-based work. The practical minimum.

512GB

The sweet spot for most people — room for apps, photos and a decent file library.

1TB

For large photo/video libraries, big games, or storing lots of work locally.

2TB

Creators and power users with large video projects, VMs or big datasets.

SATA vs NVMe

SSD types & what to avoid.

SATA SSD — the older SSD standard; still far faster than a hard drive and great for everyday use. NVMe / M.2 SSD — the newer, much faster type used in modern laptops; best for creative work and heavy multitasking. Both are excellent; for most buyers either is a huge upgrade over an HDD.

What NOT to do:

  • Don’t buy a cheap new laptop with eMMC storage — it’s slow and can’t be upgraded.
  • Don’t buy any computer with an HDD as the main/boot drive — it will feel sluggish from day one.
  • Don’t over-buy — 4K video aside, most people are happy on 512GB and can add external storage later.
  • Don’t assume you can always upgrade later — many thin laptops have soldered storage. Ask us first.

Every CLS computer has an SSD.

You don’t need to buy a separate SSD — our laptops and desktops already ship with fast SSD storage, and we can fit a larger one before despatch on request.

FAQ

SSD questions, answered.

How much SSD storage do I need?
For browsing, Office and email, 256GB is enough. 512GB is the sweet spot for most people. Choose 1TB–2TB if you keep large photo/video libraries, games or work files locally.
What’s the difference between SATA and NVMe (M.2) SSDs?
Both are SSDs and both are far faster than a hard drive. NVMe/M.2 is the newer, faster type ideal for creative and heavy work; SATA is older but still excellent for everyday use.
Do your laptops and desktops come with an SSD?
Yes — every machine we sell ships with an SSD as standard. We never use a slow hard drive as the main drive. We can also fit a larger SSD before despatch — just ask.
Can I upgrade the SSD in a refurbished laptop?
On many business laptops and most desktops, yes. Some thin ultrabooks have soldered storage. Tell us the model and we’ll confirm and fit a larger SSD before it ships.
Is an SSD or more RAM the better upgrade?
An SSD gives the biggest everyday speed jump; RAM helps with heavy multitasking. Ideally you want both — see our RAM guide. All our machines pair an SSD with 8–16GB RAM.
