Everyday external storage done right: 2TB capacity, 1.1 GB/s reads, and the reliability you expect from Transcend.

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.
At 2TB, this drive hits a sweet spot for photo and video libraries. You can store thousands of RAW images or hours of 4K footage without juggling multiple drives.
In the speed hierarchy, the Transcend ESD310C Portable 2TB 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 Transcend ESD310C Portable 2TB is a solid all-around 2TB portable SSD for everyday use. If you need fast backups, reliable file transport between devices, or external storage for documents, photos, and media, the 1,050 MB/s reads deliver performance that makes daily tasks feel instant compared to an external hard drive.
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.
Sequential read and write speeds — the numbers manufacturers advertise — matter most when transferring single large files. For everyday tasks like opening documents, browsing photos, running applications from the drive, or loading games, random 4K performance is more relevant. All NVMe-based external SSDs deliver random IOPS in the same general range, so the $Transcend ESD310C Portable 2TB feels similarly responsive to other fast portables for daily use. The real differentiator shows up during large file transfers, where the $1,050 MB/s read speed pulls noticeably ahead of slower SATA-based externals.
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.
