The first is sequential speed, which reflects how fast a drive can continually read and write large streams of data, such as raw video files; we use the CrystalDiskMark benchmark to measure this. The second is random-access performance, which gives insight into how a drive will fare when lots of programs are accessing it at once.
We test this by copying a folder full of small files to and from each drive and measuring the average transfer speed. Flash memory degrades each time data is written to it, so SSDs do have a limited lifespan. Expensive drives tend to have much greater write endurances than cheap ones, but even a low-cost SSD should last you for many years of ordinary, everyday use.
Some SSDs focus on speed, while others seek to keep the price down. These figures are impressive for this test, showing that the SX zips along even when tasked with the toughest workload. Almost no one will come near those limits within the useful life of the drive, and certainly not within the generous five-year warranty period.
If you crave the speed of a high-end SSD on a slightly more sensible budget, it hits the sweet spot perfectly.
