External SSDs offer high-speed storage expansion for laptops

External SSDs are becoming a primary solution for expanding laptop storage, particularly for devices with soldered internal drives or limited upgradeability. Biwin, a memory and storage manufacturer, notes that entry-level laptops often feature low internal capacity to reduce costs, which can be quickly exhausted by modern games and media files.

Modern external SSDs offer high-speed alternatives to internal drives. Recent models can reach sustained read and write speeds exceeding 2,000 MBps, comparable to some internal PCIe 3 SSDs. These devices typically utilize USB-C connections and are compatible with various standards, including Thunderbolt 4/5 and USB4.

In the consumer market, specific hardware like the SanDisk Extreme Portable SSD provides high-speed NVMe technology, offering read speeds up to 1,050 MB/s and write speeds up to 1,000 MB/s. Such portable units are designed for durability, often featuring silicone coatings and drop protection, making them suitable for handling large files like RAW photography or video projects on the go.
