Key takeaways
- PC and Steam Deck: run games directly from the external SSD. Fast drives help load times.
- PS5: external USB drives store PS5 games but cannot run them, while PS4 games can run from the drive. Games must be moved to internal or M.2 storage to play.
- Xbox Series X|S: an external USB 3.0 drive can run older Xbox One and 360 titles and store Series games, but Series games need the internal drive or the official expansion card to play.
- Nintendo Switch 2: its game storage uses microSD Express, so a USB drive is not a game drive.
The best external SSD for gaming for most people is the Samsung T7 Shield if you want a rugged, reasonably priced drive, and the WD_BLACK P40 or Samsung T9 if you want about 2,000 MB/s for faster installs and transfers. Speed matters less than most buyers expect on consoles, so match the drive to the platform you use before paying for the fastest model.
Quick comparison
| Drive | Best for | Rated speed | Interface | Standout feature | Price tier |
|---|---|---|---|---|---|
| Samsung T7 Shield | Rugged value | Up to about 1,050 MB/s | USB 3.2 Gen 2 | Rubber shell, IP65, 3 m drop rating | Mid-range |
| SanDisk Extreme Portable (newer model) | Durable all-rounder | Up to about 2,000 MB/s | USB 3.2 Gen 2×2 | IP65 and drop protection | Mid-range |
| WD_BLACK P40 Game Drive | Console and PC gaming | Up to 2,000 MB/s | USB 3.2 Gen 2×2 | RGB lighting, console-ready | Upper-mid |
| Samsung T9 | Speed | Up to 2,000 MB/s | USB 3.2 Gen 2×2 | Drop-resistant, large capacities | Upper-mid |
| Crucial X10 Pro | Compact speed | Up to about 2,100 MB/s | USB 3.2 Gen 2×2 | Small body | Upper-mid |
| SanDisk Extreme PRO (USB4 model) | USB4 laptops and handhelds | Higher on USB4 ports | USB4 | Needs a USB4 port to pay off | Premium |
Speeds are the makers’ maximum sequential ratings; real file copies vary with file size, port and temperature.
Best rugged value: Samsung T7 Shield
PC Gamer calls the T7 Shield its best budget durable drive. It runs at about 1,000 MB/s on a standard USB 3.2 Gen 2 port, which is plenty for loading games, and its rubber casing handles bags and desks. Its limit is sustained speed; it is not the fastest option for huge continuous copies.
Best durable all-rounder: SanDisk Extreme Portable
The newer Extreme Portable models list up to about 2,000 MB/s, IP65 water and dust resistance and drop protection. Older versions are limited to around 1,050 MB/s, so check the model number before buying. It is a good fit for people who carry a game library between machines.
Best gaming-branded drive: WD_BLACK P40
GamesRadar ranks the P40 first overall. It is rated at 2,000 MB/s, comes in 500GB, 1TB and 2TB, and adds RGB lighting and console-friendly styling. The trade-offs are the higher price and no 4TB version, so it makes more sense if you want those extras.
Best for speed: Samsung T9 and Crucial X10 Pro
Both reach around 2,000 MB/s or a bit more over USB 3.2 Gen 2×2. You only see that rate if your computer has a matching 20 Gbps port; on a standard 10 Gbps port they behave like a 1,000 MB/s drive. Check your motherboard or laptop before paying for the extra headroom.
Best for USB4 devices: SanDisk Extreme PRO
PC Gamer picks the Extreme PRO as the best USB4 external SSD for gaming. It is only worth it if your laptop, desktop or handheld has a USB4 or Thunderbolt port. On plain USB 3 you pay extra for speed you cannot use.
Worked calculation: how long does a game take to move?
Transfer time is size divided by speed. Using a 100 GB game, ideal sequential speeds give:
| Drive type | Typical speed | Time for 100 GB |
|---|---|---|
| Portable hard drive | about 100 MB/s | about 17 minutes |
| 1,000 MB/s SSD | 1,000 MB/s | about 100 seconds |
| 2,000 MB/s SSD | 2,000 MB/s | about 50 seconds |
Real transfers run slower, since many small files cut the speed and large copies can trigger cooling slowdowns. Still, the gap between 1,000 and 2,000 MB/s is under a minute per large game, which is why the cheaper drive is often the right choice.
Which platform can use it?
- PC and Steam Deck: run games directly from the external SSD. Fast drives help load times.
- PS5: external USB drives store PS5 games but cannot run them, while PS4 games can run from the drive. Games must be moved to internal or M.2 storage to play.
- Xbox Series X|S: an external USB 3.0 drive can run older Xbox One and 360 titles and store Series games, but Series games need the internal drive or the official expansion card to play.
- Nintendo Switch 2: its game storage uses microSD Express, so a USB drive is not a game drive.
These rules follow each console maker’s support pages; confirm them before purchase because firmware updates change them.
How to choose capacity
Modern AAA games often fall between 50 and 150 GB. A 1TB drive holds about 8 to 10 large titles after formatting, while 2TB roughly doubles that. If you play on a laptop or handheld, 2TB is the better balance than paying a premium for peak speed.
Format and setup tips
Most external drives arrive formatted as exFAT, which works on Windows, Mac and PS5 for storage. Xbox consoles will reformat the drive to NTFS, which erases it, so back up first. For a Windows-only game library, NTFS is the better choice since it handles large files and permissions. When you plug a drive into a console, use a port on the console itself and the supplied cable rather than a hub, because hubs often reduce speed or cause disconnects.
On PC, you can point Steam or another launcher to a library folder on the external drive. Use the Safely Remove option before unplugging, since pulling a drive mid-write risks a corrupt library that needs verifying.
Cables, ports and heat
The drive’s speed rating only applies when the port and the cable both support it. A blue USB-A port is often 5 or 10 Gbps, while only USB-C ports labelled 20 Gbps or USB4 can feed a 2,000 MB/s drive. Using the cable supplied with the drive is the safest route, because thin cables from old devices can limit it to 480 Mbps without any warning. Long copies heat the controller; if speeds fall off after the first few gigabytes, move the drive away from other hot hardware and leave air around it.
Decision matrix by situation
| Your situation | Choose | Reason |
|---|---|---|
| Steam Deck or handheld, bag use | Samsung T7 Shield or SanDisk Extreme | Rugged, power-efficient, small |
| PS5, storing PS5 games | WD_BLACK P40 or T7 Shield | Fine for storage; speed barely matters because games must move to internal storage |
| PC gamer with a USB 20 Gbps port | Samsung T9 or Crucial X10 Pro | Gets the full 2,000 MB/s |
| Laptop with USB4 | SanDisk Extreme PRO | Uses the faster interface |
| Large library on a budget | A 2TB T7 or similar | More capacity matters more than raw speed |
Mistakes to avoid
- Paying for speed your port cannot use. Check the port rating first.
- Treating the drive as a backup. A single external drive is a second copy at best; important saves should live in cloud or another disk.
- Buying too little space. Game sizes keep rising, and patches grow installs well beyond the launch size.
- Using a cheap unbranded drive. Low-cost drives can have slow controllers and short warranties, and real speed can fall far below the label.
Frequently Asked Questions
Can I play games from an external SSD?
On PC and Steam Deck, yes. On consoles it depends on the console and generation, as listed above.
Is an external SSD better than an external hard drive?
For games, yes. SSDs load faster and survive knocks better, while hard drives are only better for cheap bulk storage.
Do I need USB 3.2 Gen 2×2?
Only if you want the roughly 2,000 MB/s rating and your device has a matching port. Otherwise a 1,000 MB/s drive is almost as practical.
Will an external SSD get hot?
Fast drives warm up during long copies and may slow down to protect themselves. Metal-bodied drives usually manage this better.
How long do external SSDs last?
Makers rate endurance in terabytes written, and gaming workloads rarely approach it. The warranty period, usually several years, is the better guide.
