Buying an SSD: how to choose the right storage for your PC, laptop or console

Buying an SSD may seem straightforward, until you have to choose between an internal SSD, external SSD, NVMe SSD or traditional hard drive. Manufacturers quote high speeds and large capacities, but those figures do not always tell the whole story. The right choice depends on your device, how you use it and how you want to store your files.

Common pitfalls when buying storage

1. Choosing high speed without the right connection

According to the product specifications, an NVMe SSD with PCIe 4.0 can achieve read and write speeds of thousands of MB/s. You will only see that benefit if your computer also has a suitable M.2 slot and supports PCIe 4.0. In an older PCIe 3.0 system, the SSD may still work, but at a lower performance level.

Also pay attention to the difference between an M.2 SATA slot and an M.2 NVMe slot. They may look similar, but the technologies are not interchangeable. Always check the manual for your motherboard, laptop or handheld console.

2. Confusing capacity with usable space

An SSD 1TB or SSD 2TB does not provide exactly 1,000 or 2,000 GB of free space after installation. The operating system and formatting take up part of the capacity. Games, 4K videos and photo libraries can also fill a drive faster than expected.

For everyday use, 1TB may be sufficient. Gamers and content creators often benefit more from 2TB or 4TB. For archives and backups, an external hard drive with 5TB, 10TB or 16TB is worth considering.

3. Using an external hard drive as if it were an SSD

An external HDD contains moving parts. This generally makes this type of storage less suitable for frequent movement during data transfers. A portable SSD is more compact and has no spinning platters, while an external hard drive often offers more storage per pound.

Neither replaces a backup strategy. It is best to keep important photos, documents and projects in at least two different storage locations.

Important specifications when buying an SSD

Internal or external storage?

Choose an internal SSD if you want your operating system, programmes or games to load more quickly. An M.2 SSD is installed directly onto the motherboard. An NVMe model uses the PCIe protocol and is designed for devices with a compatible M.2 NVMe slot.

You connect an external SSD or portable SSD via USB. This is practical for backups, large media files and use with multiple devices. Check whether your computer uses USB-A or USB-C. A USB-C SSD is not automatically faster: the USB version supported by the port and the cable also help determine transfer speeds.

Speed and interface

Look out for these terms:

  • PCIe 3.0 SSD: suitable for systems with an older PCIe generation.
  • PCIe 4.0 SSD: designed for compatible newer systems.
  • NVMe: a communications protocol for fast PCIe storage.
  • USB 3.0 or USB 3.2 Gen 1: suitable for external storage, but the stated interface speed is not the same as a guaranteed file-transfer speed.
  • USB 3.2 Gen 2x2: can support higher transfer speeds, provided the device, cable and port can all handle them.

The quoted sequential speed is particularly relevant for large files. Random read and write performance also plays a role when opening small files, programmes and games.

Compatibility with gaming devices

When choosing an SSD for gaming, check the available space, form factor and heat dissipation. A PS5 SSD must meet the console’s requirements. Some M.2 models are described as PS5-compatible, but require a suitable heatsink.

Upgrading an internal SSD requires the device to be completely powered off, correct installation and often initialisation or formatting in the operating system. Back up important data beforehand. If you are unsure about installing an SSD in a laptop or console, follow the manufacturer’s instructions.

Internal SSD, external SSD or hard drive?

Use an internal SSD for faster PC start-up, quicker game loading and smoother file editing. Choose an external SSD when portability, shock resistance and short transfer times are important. An external hard drive is a good choice for large archives, media files and backups where capacity matters more than maximum speed.

A 10TB or 16TB desktop HDD usually requires its own mains adapter. A 1TB, 2TB, 4TB or 5TB portable HDD often runs from USB power. For USB-C models, check that the cable actually supports data transfer and is not suitable only for charging.

Frequently asked questions about buying an SSD

How long does an SSD last?

Its lifespan depends on the number of write cycles, temperature, usage and the quality of the controller and memory chips. Manufacturers sometimes state a TBW value, meaning the total number of terabytes that can be written to the drive according to their specifications. This does not guarantee a fixed service life. Always back up important data.

Is an SSD for gaming faster than a hard drive?

According to the product specifications, an internal NVMe SSD can offer higher transfer speeds than a mechanical hard drive. This can reduce loading and installation times. The eventual effect also depends on the game, processor, graphics card, motherboard and software settings.

How much does it cost to expand storage?

The price is determined by capacity, interface, speed, brand, warranty terms and any security features. An SSD 2TB generally costs more than an HDD with the same capacity, while an HDD of 10TB or more may be an attractive option for large archives. So do not compare only the price: also consider the price per GB, compatibility and how you expect to use it.
