#CRYSTAL DISKMARK INFO INSTALL#
Youre looking at data from an HDD, holding D: and F:, not the SSD. Read the following instructions on using CrystalDiskMark to measure read/write speed of hard disk: Download CrystalDiskMark and install it Run the application: Select the the following settings: In the left drop-down list select number of runs: 1 In central column select size to test: 50 MB In the right drop-down list select the. If you need help interpreting the disk IO data you can send them along to our support team. 3 Answers Sorted by: 2 Note ' 5400 rpm ', which is not relevant for an SSD, Id say should not be present. Currently, the program allows you to measure sequential and random read/write speeds. It displays basic HDD information, monitors S.M.A.R.T. SQL Server does a lot of random stuff in 8KB chunks, and 64KB chunks. Instead there are better tools for IO testing the database. CrystalDiskMark is designed to test the performance of your hard drives quickly. CrystalDiskInfo is an Open Source HDD health monitoring utility. To live up to server requirements you need high performance hard drives on your VisionFlow servers, especially on the database and SAN server, at least 500 MB/s but preferably faster.įor database IO tests it is better to use another tool than CrystalDiskMark since the database uses really small data chunk sizes. Smaller test file sizes may look fast but don’t really reflect how a large database will work.
