TESTING METHODOLOGY

   Memory cards are pretty much identical to flash drives so to make things easier for everyone I'll be using roughly the same testing methodology to successfully record achieved read and write data transfer numbers. The benchmark suites used for memory card tests are HD Tune Pro (Read - Write average and max speeds), AIDA 64 Engineer Edition (Average Linear Read / Random Read - Write performance), Crystal Disk Mark x64 (4GB Read / Write speeds) and ATTO (Average Read / Write speeds). Every test is repeated a total of 6 times after which the average performance numbers are recorded into the charts (0 = test was unable to complete).

   Tests are performed on the X79 test rig running Microsoft Windows 10 Pro installation on a HyperX Predator 480GB PCIe SSD with all updates installed up to the day of this review (for ATTO and Crystal Disk Mark cards are formatted using the NTFS file system – however partitions need to be removed for the write tests of both AIDA64 and HD Tune Pro).

* As of April 2020, I’ll be using the X299 test rig for SDXC & microSDXC UHS-II (and above) memory card reviews.
** As of March 2022 the Z590 test rig will be used for memory cards requiring a USB 3.2 Gen 2x2 card reader.
