What is a portable hard drive? A portable hard drive is a lightweight, high-capacity external storage drive (similar to a beefier USB flash drive) that connects to our computers, TVs, and other devices to expand their storage (or more commonly copy large files between devices).
Sequential read/write speeds are only 100–200 MB/s, with slow random read/write performance (approximately 100–200 IOPS). Multitasking often results in lag.
Sequential read/write speeds reach 500–7000 MB/s (NVMe protocol), with outstanding random read/write performance (IOPS exceeding 100,000), enabling extremely fast system boot-up and file transfers.
A portable hard drive is a device for storing data. It is suitable for large-capacity storage, easy to carry, and plug-and-play. Portable hard drives are the mainstream tools for future large-capacity storage.
