WHAT DOES CRYSTAL DISK MARK DO WINDOWS

It works by constantly reading and writing precisely sized blocks of data from various storage disks. I think all the data it's pushing (data = electricity) we may need to begin putting heatsinks on the NAND chips. CrystalDiskMark is a storage benchmarking utility that can test the performance of read and write operations of storage disks in your computer. Using this tool will help you quickly determine if your storage device is performing as it should. It generates read/write speeds in sequential and random positions with varying numbers of queues and threads. The issue was benchmarks were nearly all 1 thread. CrystalDiskMark works by reading and writing through the filesystem in a volume-dependent way. Early benchmarks from pcper showed that the programming of benchmarks needed to be changed since CPU speeds began to affect benchmarks. SATA SSDs will max out sequentials for their maximum rates.

$10 Flash drives have embarrassing random 4k writes WELL under 1. HDDs have slow random 4k reads usually under 1. I've seen 8 queue only when I directly stress the disk and is beyond everyday use.Īs for different values, there are only the obvious ones.

Only when you do windows udpates/spyware scan will you see 1-4 queue. With SSDs it's almost always below 1 queue. IMO is trying to measure the advantage of going NVMe. I wouldnt be concerned with it unless you are. The average user probably writes no more than 10 TB per year. Trying to measure the maximum speed of the interface minus any CPU help.ĤKQ32T8 = 4k, 32 Queue, 8 Thread, Means 4k (most common smallest block of data) 32 requests, 8 simultaneous. Autobahn said: When CrystalDiskInfo is running does it continuously read/write anything to the hard drive, which from what Ive read is not good for a SSD You can easily track how much you are writing to the SSD. SeqQ32T1 = Sequential, 32 Queue, 1 Thread, Maximum speed with 32 disk requests, one CPU instruction or one at a time. Based on Microsoft's MIT-licensed Diskspd tool, this graphical benchmark is commonly used for testing the performance of solid-state storage. In the top bar there are five menus: namely Fillet, Settings, Profile, Subject, e Language (Language). CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. The last two results seq (Sequential) and 4k hasn't changed. Regardless of the version you have decided to download, Crystal Disk Mark allows you to benchmark through the same options. This is efficient application designed as a benchmark system for your hard drive, enabling you to assess read and write speeds.
