Reliable 2TB storage with 1.1 GB/s reads — the Transcend ESD310C Portable 2TB is a practical, affordable choice for daily backups and file transport.
With 1.1 GB/s reads and 950 MB/s writes over a USB-C connection, the Transcend ESD310C Portable 2TB 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.
2TB of storage provides generous headroom for everyday files. The compact, lightweight design slips into any bag pocket. 1,200 TBW endurance exceeds what most consumer drives offer — engineered for creators who write terabytes per week. Backed by a 3-year warranty, this drive offers typical protection for its class.
2TB provides generous headroom for creative workflows — a working photo library, active video projects, and a game library all on one portable drive.
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 Transcend ESD310C Portable 2TB 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 2TB portable SSD.
At 2TB, 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.
The USB 3.2 Gen 2 interface means the Transcend ESD310C Portable 2TB 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 Transcend ESD310C Portable 2TB delivers 1,050 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 1,050 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 Transcend ESD310C Portable 2TB is rated for 1,200 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 66 years to reach its endurance limit. For typical use patterns involving backups, file transfers, and game storage, the 1,200 TBW rating provides comfortable headroom well beyond the 3-year warranty period.
