Read Speed and the Write-Speed Catch
Samsung quotes read speeds of up to 300MB/s over USB 3.1, and in everyday use reading is where the drive shines: files open quickly, media plays straight from it and software run from the drive responds well. One owner moved frequently used apps onto it to speed up an ageing office computer and found them launching noticeably faster. Writing is much slower. That is typical of compact flash drives, which put their effort into reads, and it shows up when copying large files onto the drive: one owner who benchmarked three units found consistent results but writes well below reads, and another found that copying a large batch of files took an hour or more. For documents, photos, music and backups of modest size it hardly matters. For regularly moving large video projects, it is the main limitation.
