CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.

CrystalDiskMark shows some interesting things. Here, the T5 puts up some strong numbers in the sequential and large file transfer tests. And it also does well with 4K transfers, though it actually trailed the T3. Once the queue depth is increases, the limitation of the USB-C interface holds the drive back versus the SATA-based offerings, though it still has no trouble dispatching the T3 or slower USB thumb drive.
