Score: 62/100Rankings
The SanDisk Extreme Portable SSD 1TB delivers high-performance NVMe speeds of up to 1,050 MB/s read and 1,000 MB/s write while offering IP65 water and dust resistance in a lightweight 52 g package. Its capacity is limited to 1 TB and it lacks the ultra-fast 2,000 MB/s class of newer models. Ideal for creators and mobile professionals needing fast, rugged portable storage.
The Fanxiang S101 1TB SATA SSD offers an affordable upgrade path for older laptops and desktops, delivering up to 550 MB/s read speeds with reliable TLC NAND. Its limitations include the SATA III bandwidth ceiling and lack of advanced features such as DRAM cache or hardware encryption. It is best suited for budget-conscious users needing a simple storage boost on legacy systems.

Professional reviewers commend the Extreme Portable SSD 1TB for its high sequential read speed, noting it delivers smoother playback when editing video files. They also appreciate its lightweight, bus-powered design and the inclusion of both USB-C and USB-A adapters, which together make it a solid choice for creators on the move.
Everyday users have limited publicly documented feedback, but the available comments emphasize appreciation for the drive's speed, portability, and cross-platform compatibility.
Professional reviewers consider the S101 a solid, low-cost option for users who need a simple SATA upgrade. While it delivers the expected speed gains over HDDs, its SATA III bandwidth and lack of premium features make it unsuitable for performance-critical workloads, and external use via USB shows markedly lower speeds.
“the speed of this SSD mainly when reading files will provide smoother playback”
