How to choose a hard drive (HDD) in 2026 — and do you still need one?

CMR or SMR, form factor, speed, capacity and reliability: the buying guide

By the FlowUP team, gaming PC builder in Genappe (Belgium) · Updated 29 September 2026

In short: in 2026, a hard drive (HDD) is no longer the main drive in a gaming PC: Windows and games go on an NVMe SSD. The HDD remains, however, the best choice for storing lots for cheap: archives, videos, backups, NAS. To choose well, four criteria: the recording technology (CMR rather than SMR), the form factor (3.5-inch for a desktop PC, 2.5-inch externally), the spindle speed (7,200 RPM if you often copy large files) and the capacity (4 to 8 TB for most players).

Is the HDD still useful in 2026?

Yes, but no longer for the same reasons as before. A hard drive reads at about 200 MB/s, whereas a recent NVMe SSD runs at several thousand: for booting Windows and games, there’s no contest. Some games, like Call of Duty Black Ops 7, even require an SSD in their minimum configuration. The details of the figures are in our comparison SSD or HDD in 2026.

Where the hard drive remains unbeatable is on the price per terabyte. With the rise in flash memory prices in 2026, the gap has even widened. For everything that doesn’t need speed, it remains the most logical solution.

UseIs an HDD suitable?
Photo and video archives, rushes, exportsYes
A large library of films, music, ISO filesYes
Local backup (in addition to the cloud)Yes
NAS (network storage, Plex, automatic backups)Yes, with CMR NAS drives
Windows and softwareNo, SSD required
Recent games, especially open-worldNo, risk of stuttering when loading scenery

CMR or SMR: the criterion you forget most

Not all hard drives write data the same way. With CMR (conventional recording), tracks sit side by side. With SMR ("shingled" recording), they overlap to gain capacity, but any rewrite forces the drive to reorganise neighbouring tracks. Result: throughput that collapses during large transfers, and well-known problems in NAS or RAID setups.

The issue caused quite a stir in April 2020, when Western Digital admitted to having slipped SMR into certain WD Red drives intended for NAS without clearly stating it. Since then, the brand distinguishes WD Red (SMR on some capacities) from WD Red Plus and Red Pro (CMR). At Seagate, several 3.5-inch BarraCuda models (2, 4 and 8 TB) are SMR, while the company claims it uses no SMR in IronWolf and IronWolf Pro.

Simple rule: if in doubt, choose CMR.

Hugo Fortier explains in a video how CMR and SMR work, and what impact they have on a NAS:

Hugo Fortier, “SMR/PMR/CMR drives: how does it work? What impact on NAS performance?”, November 2021.

3.5 or 2.5 inches, 5,400 or 7,200 RPM

Form factorAdvantagesIdeal for
3.5 inchesMore capacity, better €/TB, often fasterDesktop PC, NAS, large storage
2.5 inchesCompact, powered by USB externallyLaptop, portable external drive

When it comes to spindle speed, a drive with 7,200 RPM delivers better throughput and faster access: it’s the right choice if you frequently copy large files or work on videos. A 5,400 RPM drive is quieter and runs cooler, perfect for archives and backups.

Which capacity should you choose?

ProfileRecommended capacity
Light documents and backups2 to 4 TB
Gamer with a video library and captures4 TB in CMR at 7,200 RPM
Gamer with a large game library and backups8 TB in CMR
Streamer or creator (4K rushes, large projects)8 to 16 TB in CMR, plus an external backup
NAS at homeDedicated NAS drives in CMR, capacity based on your needs

On a hard drive, between “faster” and “bigger”, capacity is often the best investment: that’s why you buy it.

Reliability: what can you expect?

Backblaze publishes every year the failures affecting its tens of thousands of drives. In 2025, the annual failure rate for its fleet (344,196 drives, 30 models) was 1.36%, down from 1.55% in 2024. In other words, the vast majority of drives last for years, but a failure can always happen: a hard drive is never a backup on its own. On the warranty side, count on 2 years for a Seagate BarraCuda and 3 years for an IronWolf, according to the manufacturer’s datasheets.

Internal or external? And why not an external SSD?

A internal hard drive (SATA) is installed in a desktop PC and simply acts as a storage drive. A external hard drive (USB) is handy for backups and for transporting data, as long as you protect it from shocks: an HDD really does not like that, especially when it’s running.

For storage that travels in a bag, an external SSD is often a better choice: much faster, more drop-resistant, and more compact. The external hard drive still has the advantage of price per terabyte for large-scale archiving, something you only plug in from time to time.

Our formula: an external SSD from 1 to 2 TB for frequent backups and ongoing projects, and an external hard drive for the archive.

And what about games?

You can store games on an HDD, but loading times increase significantly: recent open-world titles may stutter while loading environments, and updates take longer. The right strategy: Windows and the games of the moment on the SSD; games you rarely launch, and your archives and gameplay recordings on the hard drive.

FAQ: hard drives in 2026

Is a hard drive still useful in 2026?

Yes, for storing a lot of data at low cost: archives, videos, backups, NAS. Not for Windows or games, which should be on an SSD.

Can you play with a hard drive?

For older games or lighter titles, yes. For recent games, no: long loading times, stuttering in open worlds, and some games require an SSD.

CMR or SMR, which one should you choose?

CMR in almost all cases, and mandatory for a NAS or frequent backups. SMR only has an advantage for archiving that is rarely rewritten.

5,400 or 7,200 RPM?

7,200 RPM if you often copy large files; 5,400 RPM for archives and backups, quieter.

What hard drive capacity for a gamer?

4 TB is enough for most gamers for captures and games you don’t use often; 8 TB if you keep a large library and your backups.
