Expand your game library with the Corsair EX100U — 2.0TB of 1.6 GB/s NVMe storage purpose-built for consoles and gaming PCs.
1.6 GB/s reads means games load 3-5× faster than from an external HDD. The Corsair EX100U eliminates the lag between pressing start and being in the action — whether you are fast-traveling across a map or loading into a multiplayer match.
Roughly 25-51 AAA games fit on 2.0TB — enough to keep your current rotation installed without juggling uninstalls every time a new title drops.
At 1.6 GB/s reads, this is one of the fastest USB drives you can pair with a console. Load times will rival internal SSD performance for many titles.
While USB-connected externals store and play Xbox Series X|S and PS5 titles, native internal SSDs may be required for full next-gen optimized performance on certain titles.
The Corsair EX100U targets users who need maximum throughput from an external drive. If you edit 4K or 6K video, move large project files between workstations, or work directly from external storage, the 1,600 MB/s read speed puts this drive in elite territory for a 2.0TB portable SSD.
At 2.0TB, this drive hits the sweet spot for users with substantial storage needs. Photo and video libraries, game collections, and professional project files all benefit from the headroom — you will not be juggling free space or swapping files between drives.
One important note: reaching the full 1,600 MB/s requires a USB 3.2 Gen 2x2 (20 Gbps) host port. On a standard USB 3.2 Gen 2 port, the drive still works perfectly but negotiates down to 10 Gbps. Most laptops from 2022 onward include a compatible port on premium models, but verify your hardware before expecting peak performance.
On paper, the Corsair EX100U delivers 1,600 MB/s reads and 1,500 MB/s writes. In practice, a 50GB file — a typical 4K video project, a large game install, or a full photo shoot — transfers in ~33 seconds. A 100GB batch of raw files moves in ~1 minutes. For users who regularly shuttle large files, these transfer times are a meaningful productivity improvement over slower SATA-based externals that take 3-5x longer for the same tasks. Note: those numbers describe large sequential transfers — everyday tasks (opening documents, app launches, game loads) feel equally fast across all NVMe portables because random 4K performance is similar drive-to-drive.
The 1,600 MB/s peak is achievable for burst transfers, but sustained writes of 100GB or more will see speeds settle to approximately 1,275-1,350 MB/s as the controller manages thermals. This is normal for compact NVMe enclosures and does not affect everyday use — only continuous large-file writes are impacted.
The Corsair EX100U is rated for 900 TBW (terabytes written) endurance. To put that in perspective: if you write 50GB per day — an aggressive daily workload for most users — the drive would take approximately 49 years to reach its endurance limit. For typical use patterns involving backups, file transfers, and game storage, the 900 TBW rating provides comfortable headroom well beyond the 3-year warranty period.
