Buying an SSD: How to choose the right storage for your laptop, desktop or console

An SSD often makes a computer noticeably more responsive, but not every drive is compatible with every device. If you only focus on high read speeds, you could end up with an SSD that doesn't fit your laptop, isn't cooled sufficiently, or barely works any faster due to a limited connection.

The main pitfalls when buying an SSD are:

  • High speed without the right connection: A PCIe 5.0 SSD offers little added value in a system that only supports PCIe 3.0 or SATA.
  • Wrong physical size: M.2 is a connector type, not a guarantee that every M.2 SSD will fit your device. For example, check if your laptop supports M.2 2280.
  • Underestimating capacity: A 1TB SSD might seem spacious, but the operating system, games, video files and temporary files can quickly take up space.
  • Forgetting about cooling: Fast NVMe SSDs can get hot during sustained transfers. Without adequate airflow, the speed may temporarily drop.

Which SSD is right for your device?

Internal SSD or external SSD

An internal SSD is installed inside a laptop, desktop or console. This provides a neat, permanent storage upgrade, but you'll need to check the connection type and may require some installation know-how.

An external SSD works via USB and is more practical for backups, photo libraries and taking files with you. A portable SSD like the DigiEra uses USB-C. The specified speed of up to 2,000 MB/s is only achievable if the computer, mobile phone or console also supports USB 3.2 Gen 2x2. With an older USB port, the transfer rate will be lower.

SATA SSD versus NVMe SSD

A 2.5-inch SATA SSD uses the Serial ATA III interface. The Kingston A400 models in this selection, for example, have specified read speeds of up to 500 MB/s. This is suitable for an older laptop or desktop that has a hard drive and a SATA connection.

An NVMe SSD typically uses the M.2 form factor and the PCIe bus. According to the product specifications, a PCIe 4.0 SSD can reach several thousand MB/s. A PCIe 5.0 SSD goes even further, but requires a compatible motherboard, sufficient cooling and, in some cases, an active fan. For everyday office work, such an extra-high speed isn't always necessary.

Three specifications to check beforehand

1. Connection and form factor

Check the manual for your laptop, desktop or PlayStation 5:

  • Is there an M.2 slot available?
  • Does the slot support NVMe PCIe or only M.2 SATA?
  • Is the length 2280, i.e. 22 × 80 mm?
  • Is there space for a heatsink?
  • Does the PS5 have an expansion slot that meets the required PCIe specification?

For a PS5 SSD, the interface isn't the only important factor. The console also has requirements for dimensions and cooling. According to the product information, the Lexar NQ790 is listed as PS5-compatible, but it requires a heatsink. The Samsung 990 PRO with heatsink is also listed as PS5-compatible in its product specification. Always check the latest guidelines from Sony and the size of the heatsink before installation.

2. Read speed, write speed and use case

Manufacturers usually list sequential read and write speeds. These are useful for large files, such as video projects or game installations. For normal browsing and word processing, other system components like the processor, RAM and software also determine the perceived speed.

For gaming, a gaming SSD with NVMe and PCIe 4.0 is often a practical middle ground. Content creators who move large video files may benefit more from a 2TB or 4TB SSD with a high write speed. Also, look at the specified TBW (Terabytes Written) value if you write large amounts of data daily. This is an indication of the specified write load, not a guarantee that a drive will fail immediately afterwards.

3. Capacity and backup

Choose a capacity based on your usage:

  • 500GB to 1TB: Suitable for office work, studying, the operating system and a limited game library.
  • 2TB SSD: Handy for multiple large programs, games, photos and video projects.
  • 4TB SSD: A good option for large media collections, work files and extensive game libraries.

An SSD is not a substitute for a backup. Always keep important files in a second location, such as a NAS, external drive or cloud storage.

Frequently asked questions about buying an SSD

Is an NVMe SSD always faster than a SATA SSD?

According to the specified interface and speed specifications, an NVMe SSD can offer significantly higher sequential speeds. However, the actual difference depends on the device, the software and the type of files. For an older computer with only SATA ports, a SATA SSD is a more suitable choice.

How much storage do I need?

For a basic laptop, a 1TB SSD is often sufficient. Gamers and users with lots of photos or videos will usually find 2TB to be a more practical choice. If you store large projects locally, you might consider 4TB. Also, remember to leave free space for updates and temporary files.

How long does an SSD last?

The lifespan depends on the write load, temperature, usage and model. Manufacturers sometimes state a TBW value and a mean time between failures (MTBF) in the product specifications. You should view these figures as technical guidelines. Always make backups of important data and install firmware updates according to the manufacturer's instructions.
