crystal disk mark output sandisk ultra 200 gb

Calculate 1GB = 1000MB like the SanDisk package does.)īenchmarks and real-world writes are reporting two different write speeds, but real-world numbers (~14MB/s writes) measured during everyday file writes to the card seem more consistent.I've been looking at these and wonder if they worked with the MPZ.ĭji sales scan disk and the Evo's are a lot cheaper, but no one talks about using them. (Read this as: “If you write data at a speed of 13.9 MB/s for 7620 seconds, how much data will you have written?” The result of 105918MB (almost 106GB) is close to the actual 106GB of written data.

Hmm… This is still a reasonable write speed for a class 10 microsd card, but much higher than the Disks and CrystalDiskMark benchmarks show. This averages to about a 13.9 MB/s write speed (almost 14 MB/s). It took 127 minutes to copy 106GB worth of data to the SanDisk 200GB microsd. To test this, I copied a few thousand miscellaneous files from a mechanical drive (~85MB/s read/write) to the SanDisk 200G connected via a USB 3.0 adapter. Command line was used with time. exFAT tended to show a 2-5MB write speed increase over FAT32 in both Linux Mint 18 and Windows 7, However, FAT32 is far more universal and enjoys much greater compatibility with various devices, so FAT32 is my preferred choice.

exFAT or FAT32?įrom these benchmarks and from everyday, usage, there is practically no real-world difference in performance between exFAT and FAT32. Then again, Disks will always report lower numbers than CrystalDiskMark because they are two different benchmarking programs. Certainly not class 10 (10MB/s) write speeds. This card might transfer a few files at first at ~20MB/s, but remaining writes continue at a slower 4-6 MB/s. This makes me suspect the accuracy of the CrystalDiskMark test and its 20MB/s results. While low, this is actually similar to other microsd benchmark write speeds. In both cases, the write graph begins around the 9-18MB/s range, but as the writing continues, writes drop to 4-6MB/s for the rest of the benchmark. Read speeds remain consistent around 86 MB/s.ĭisks revealed something other online reviews have demonstrated also: The write speeds start with a bang, but they soon drop to low speeds and remain there. Again, we see the slight increase in write speed with exFAT over FAT32 with the SanDisk 200G.
