It combines both read and write tests with transfer ratios manually selectable (default is 70% read and 30% write). We also run a test recently added to CrystalDiskMark called Mix.

The CrystalDiskMark test file size is set to 256MB and each test is run with 5 passes to give an average. This is what really sets a solid state drive apart from a mechanical hard drive in terms of performance.Įach RAM disk created is 512MB in size (or close to it) and formatted to NTFS. You’ll notice the 4K scores in particular for the SSD are vastly superior. The next screenshot is a typical NVMe SSD result. The screenshot below shows a CrystalDiskMark result from a standard 7200RPM hard drive. Depending on the intended use for the RAM disk, one set of scores may be more important than the other.Ī good score in both 4K and sequential tests would be the best result for general all round good performance. The 4K scores test small file performance while Sequential (Seq) scores test the speed of transferring larger files. The popular CrystalDiskMark tool is used to run the benchmark. Here we look at 11 free programs that can create RAM disks and run a performance test to see how fast each program is when reading from and writing to the RAM disk. Better coded and optimized RAM disk software really can make a difference in how well the disks perform. Although you might think RAM disks all work at the same speed because they use the same physical RAM, that is not the case. There are several applications around that can create RAM Disks for you, some are shareware or commercial products but quite a few are free to use. For example, we’ve talked previously about how Firefox performance can be improved by storing some of its files in RAM. Another usage scenario is storing specific programs or data files you use often for faster loading. One common usage is storing the system temporary files or cached files from your web browser or other software. RAM Disks can be very useful and if you have the memory available, using system RAM as a disk drive can really speed up certain operations.
