![]() On SSDs it can make a huge difference reading small files, since the time it takes for the drive to transfer the data to the computer can be a lot longer than the time to read the data. It doesn't make much difference on HDDs since you're mostly limited by the physical speed of the platter and read/write head. That is, you queue up a bunch of read/writes in the drive, and the drive does them as quickly as it can. For a modern drive, it's about 0.7-1.3 MB/s. There's OS and drive overhead in locating the file, then the time associated with moving the read/write head to the proper location and waiting for the right section of the platter to spin under the head. On many larger drives, this is the smallest cluster size, so it's the lower speed limit. For a modern 7200 RPM drive, it ranges from about 80-160 MB/s today.Ĥk is the speed at reading/writing really small files (4KB in size). So if you were copying a bunch of 1GB movie files (which weren't fragmented), the sequential speed is what you'd expect. Sequential is the speed at reading/writing big files. ![]() 3 are standard CDM results, 1 is not, and you're missing 1 which is standard. Not sure how you got CrystalDiskMark to produce those results.
