Buying an SSD: how to choose the right storage for your PC, laptop, gaming and mobile use

Buying an SSD seems straightforward until you have to choose between an internal SSD, external SSD, NVMe SSD, M.2 SSD or portable SSD. Manufacturers quote high read speeds, large capacities and new PCIe standards, but those figures don’t tell the whole story.

The most important question isn’t which SSD has the highest speed on the box. It’s whether the drive is right for your device, connections and the way you work.

Common pitfalls when buying an SSD

1. High speed without a suitable connection

On paper, a PCIe 5.0 SSD can be much faster than a PCIe 4.0 SSD. However, if your motherboard only has a PCIe 3.0 or PCIe 4.0 slot, your system will limit its speed. The same applies to an external SSD: a model with USB 3.2 Gen 2x2 will only reach its stated speed if your computer supports this standard too.

So check the following beforehand:

  • Which PCIe generation your motherboard or laptop supports.
  • Whether the M.2 slot supports NVMe, rather than SATA only.
  • Which USB version your computer, smartphone or console uses.
  • Whether the right cable is included.

2. M.2 doesn’t automatically mean NVMe

M.2 mainly describes the SSD’s form factor. An M.2 SSD can use SATA or NVMe. An NVMe SSD uses PCIe and is generally capable of higher transfer speeds. An M.2 SATA drive has the same physical form, but a different interface.

So when looking for a drive for your laptop or desktop, don’t just search for “M.2”. Also check for:

  • M.2 2280: the most common length for desktops and many laptops.
  • NVMe: the protocol for PCIe storage.
  • PCIe 3.0, PCIe 4.0 or PCIe 5.0: the supported connection standard.
  • Available space for a heatsink.

3. Underestimating storage capacity

A 1TB SSD is suitable for Windows, programmes, photos and a number of games. For large game libraries, 4K video or lots of RAW photos, a 2TB SSD may be more practical. A 4TB SSD gives you more space, but usually costs more and isn’t necessary for everyone.

Remember to leave some free space. An SSD that’s almost full all the time gives you less flexibility for temporary files, updates and video projects. For important files, a separate backup is still essential; an SSD isn’t a substitute for a backup strategy.

Which specifications really matter?

Internal or external SSD?

An internal SSD is installed directly in a desktop, laptop or, in some cases, a PlayStation 5. It’s usually the natural choice if you want your operating system, games or programmes to load faster.

An external SSD connects via USB and is handy for backups, large media files and use on the go. A portable SSD such as the Samsung T7 is easy to move between Windows, macOS, Android devices, cameras and consoles. Always check that your device and file system are compatible.

Sequential speed and everyday use

The stated read speed, for example 7.000 MB/s, is generally a maximum sequential speed. This matters when working with large files, editing video and transferring data for extended periods. For everyday office work or opening small files, random read performance, system software and the processor also play a part.

So a fast SSD won’t automatically make an older system faster in every respect. The connection and other hardware also affect the result.

Heat, heatsinks and PS5 compatibility

NVMe SSDs can get warm during extended transfers. A heatsink helps dissipate heat, but it needs to fit in the available space. If you’re choosing an SSD for PS5, pay particular attention to the dimensions, including the heatsink. Also check the console’s requirements before installing an internal drive.

A model without an integrated heatsink can work perfectly well in a desktop if the motherboard has its own M.2 cooler. Laptops often have less clearance.

Recommended SSDs for different user profiles

Suitable for: Budget-conscious beginners

Frequently asked questions about buying an SSD

Which SSD do I need for a laptop?

First, check the type of connection. A laptop may have an M.2 2280 NVMe slot, a 2.5-inch SATA bay or both. Check the laptop’s manual or specifications. With an M.2 SSD, also check its length and maximum thickness.

How long does an SSD last?

Lifespan depends on usage, memory technology, temperature and the amount of data written. Manufacturers sometimes list a TBW rating, which indicates the total number of terabytes that can be written to the drive according to its specifications. Always back up your data, even if your SSD is still within its expected lifespan.

Is a PCIe 5.0 SSD worth the extra cost?

It depends on your system and what you use it for. PCIe 5.0 may be worthwhile for large video files, professional applications and some gaming PCs. For everyday use, gaming and many creative tasks, a PCIe 4.0 SSD already offers plenty of performance. Also check that your motherboard supports PCIe 5.0 and that adequate cooling is available.
