A 1TB WD My Passport SSD with a slim profile and 256-bit AES hardware encryption. The slim metal-and-plastic body is half the thickness of WD's non-SSD My Passport HDD — both USB-C and USB-A cables are included, removing the classic "Mac needs a converter" hassle.

Reliable 1TB storage with 1.1 GB/s reads — the WD My Passport SSD Portable 1TB is a practical, affordable choice for daily backups and file transport.
With 1.1 GB/s reads and 1.0 GB/s writes over a USB-C connection, the WD My Passport SSD Portable 1TB delivers reliable performance for daily computing needs. Backing up documents, transferring photos from a laptop to a desktop, or storing a media library — it handles routine tasks with consistent speed.
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.
SATA-based externals like the WD My Passport SSD Portable 1TB are the sensible choice when NVMe speed is overkill — the 550 MB/s ceiling is plenty for system backups, media playback, and document storage, and the savings are significant.
The WD My Passport SSD Portable 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 1,050 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 WD My Passport SSD Portable 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 1,050 MB/s performance without compatibility concerns.
On paper, the WD My Passport SSD Portable 1TB delivers 1,050 MB/s reads and 1,000 MB/s writes. In practice, a 50GB file — a typical 4K video project, a large game install, or a full photo shoot — transfers in ~50 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 1,050 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 WD My Passport SSD Portable 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.
