diglloydTools classic is deprecated, but still runs on macOS 10.6 through macOS Ventura . Older versions can be downloaded for use back to OSX 10.6. At their most powerful using the command line (Terminal), simple GUI wrappers are provided also.
DiskTester is performance testing software for your hard drives and solid state drives, especially RAID. DiskTester will tell you how your drives are performing, map out bad sectors, and help track down problems. DiskTester can also recondition an SSD quickly and conveniently.
MemoryTester enables you to stress-test your memory and Mac before you put it into "production" use. It helps prove that the machine and memory are reliable. No other tool can push the machine to its limits like MemoryTester can.
IntegrityChecker enables you to verify your files and backups, detecting even single-bit errors. With IntegrityChecker, you can be sure that the files you have copied, backed-up or restored are perfect, even years later.
