A 950 MB/s Gen 2 portable in a brushed-aluminum case the size of a credit card. The SL100 Pro is one of the smallest 1TB Gen 2 SSDs at retail — buy it for the form factor, not the rated speed (which undershoots the Gen 2 ceiling).

1TB of 950 MB/s storage for everyday use — the Lexar Lexar SL100 Pro 1TB delivers reliable performance without the premium price tag.
The Lexar Lexar SL100 Pro 1TB offers 950 MB/s reads and 950 MB/s writes — enough for everyday computing without breaking the bank. System backups, file transfers between machines, and external media storage all run smoothly.
1TB of storage provides generous headroom for everyday files. The compact, lightweight design slips into any bag pocket. 600 TBW endurance covers moderate daily use across a multi-year lifespan. The 3-year warranty provides standard coverage for the expected lifespan of the drive.
This drive delivers SATA-class speeds over USB — adequate for documents, photos, and backups, but video editors should budget for a faster NVMe-based external.
In the speed hierarchy, the Lexar SL100 Pro 1TB sits above HDDs and below NVMe. Think of it as a SATA SSD in your pocket — fast enough for 95% of daily tasks at a fraction of the cost of the fastest USB drives.
The Lexar SL100 Pro 1TB is a solid all-around 1TB portable SSD for everyday use. If you need fast backups, reliable file transport between devices, or external storage for documents, photos, and media, the 950 MB/s reads deliver performance that makes daily tasks feel instant compared to an external hard drive.
The 1TB capacity covers most daily workflows comfortably: system backups, a working photo library, a dozen game installs, or a collection of documents and media. If you need more space, higher-capacity variants of the same product line are worth considering.
The USB 3.2 Gen 2 interface means the Lexar SL100 Pro 1TB hits full speed on virtually any modern USB-C or USB-A port — no special hardware required. Plug it into a laptop, desktop, game console, or tablet and you get the same 950 MB/s performance without compatibility concerns.
On paper, the Lexar SL100 Pro 1TB delivers 950 MB/s reads and 950 MB/s writes. In practice, a 50GB file — a typical 4K video project, a large game install, or a full photo shoot — transfers in ~53 seconds. A 100GB batch of raw files moves in ~2 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 Lexar SL100 Pro 1TB is rated for 600 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 33 years to reach its endurance limit. For typical use patterns involving backups, file transfers, and game storage, the 600 TBW rating provides comfortable headroom well beyond the 3-year warranty period.
