A compact 1050-class Gen 2 portable at a budget price point. The SE800 is one of the cheapest brand-name 1TB external SSDs in retail — the cost-cutting shows in the plastic body and shorter warranty.

The ADATA SE800 1TB: 1TB, 1.0 GB/s reads, 950 MB/s writes, and a price that makes it an easy choice for daily backups and file transport.
The ADATA ADATA SE800 1TB offers 1.0 GB/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 balances durability with affordability — suitable for regular use with room to spare. Backed by a 3-year warranty, this drive offers typical protection for its class.
This speed range is typical of a SATA SSD running over USB — noticeably faster than any HDD, but well below what NVMe drives achieve over Gen 2x2 or Thunderbolt.
This drive performs like a SATA SSD over USB — roughly 5-6× faster than an external HDD for random reads, but not in the same league as NVMe-based externals. For documents, photos, and backups, the difference is academic.
The ADATA SE800 1TB 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 1,000 MB/s read speed puts this drive in elite territory for a 1TB portable SSD.
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 ADATA SE800 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 1,000 MB/s performance without compatibility concerns.
On paper, the ADATA SE800 1TB delivers 1,000 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.
At 1,000 MB/s, thermal throttling is minimal during typical use. Only sustained sequential writes exceeding 100GB — such as backing up an entire media library in one pass — may cause the controller to reduce speeds temporarily. For everyday transfers and backups, you will consistently see performance near the rated specifications.
The ADATA SE800 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.
