Solid-state drives tend to excel at random IO, as unlike hard drives, they do not need to seek for the specific position to read from or write to. It generates read/write speeds in sequential and random positions with varying numbers of queues and threads. It works by reading and writing through the filesystem in a volume-dependent way. Based on Microsoft's MIT-licensed Diskspd tool, this graphical benchmark is commonly used for testing the performance of solid-state storage. So - I am curious as to what these different categories actually mean? I've tried to look on youtube and online - only to find basic information.English, Japanese, Russian, Chinese, etc.ĬrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Results are presumably below par as the USB3.0 adapter is bottle necking - was too lazy to unplug and open my case to hook up to SATA - besides, wanted to get actual USB 3.0 results that I could expect - as the setup is being used specifically for my Xbox One to get some better performance out of certain games.įinally - just for the hell of it, I ran the test on my 1TB Western Digital Passport, external HDD - and WOW! I had no idea how slow HDD's were compared to SSD's!!!! (Also presumably slower than a HDD connected thru SATA)

Test : 1024 MiB (x5) Īlso, I found a 250gb Samsung 850 EVO at work, which I formatted and I have hooked up via a USB3.0 Case Adapter.
