DiskMark - harddisk benchmark at Mac App Store analyse

Test the performance of your solid state drives (NVME/SATA), hard disk drives and flash drives (pen/usb) in just one minute. DiskMark performs real world speed tests and shows: + Sequential read/write speeds which is the performance you see when copying large files. + Random read/write speeds which is the performance you experience when opening or using programs that read and write a lot of files to disk. DiskMark is extremely simple to use and invaluable if you work with any USB drives (flash or external harddisks). It also exhausts I/O buffer caches, resulting in highly accurate results which you can expect to see in real life. A history of benchmarks lets you quickly compare your own drives. The latest NVME/M.2 SATA SSDs employ various techniques such as SLC caching and DRAM buffers to showcase better speeds. DiskMark is specifically built to take these into account so that the read/write performance reported in the benchmark is as close to the real-life performance. Lifetime upgrades are included when you purchase the app. We dont have any recurring charges or in-app purchases in any of our apps.
