It generates read/write speeds in sequential and random positions with varying numbers of queues and threads. It works by reading and writing through the filesystem in a volume-dependent way. Based on Microsoft's MIT-licensed Diskspd tool, this graphical benchmark is commonly used for testing the performance of solid-state storage. This benchmark tool measures the performance of a storage device by testing its sequential read and write speeds as well as its random read and write speeds using blocks 512K and 4K in size. CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Looking at the screenshot above, you can see that it performs equally well with both incompressible (0%) and compressible (100%) data.įirst, I ran a few quick tests using CrystalDiskMark. Like the M6M, the M5S is based on Marvel's 88SS9188 controller chip. For comparison, I've also included test results from the Toshiba Q Series Pro, Plextor PX-256M6M, Samsung SSD 840 EVO mSATA, OCZ Vector 150, OCZ Vertex 450, Silicon Power Slim S55, Samsung SSD 840 EVO, Seagate 600 SSD, SanDisk Extreme II, Plextor PX-256M5M, OCZ Vector, Plextor PX-256M5Pro Xtreme, Samsung SSD 840 Pro, Samsung SSD 840, Kingston Ultra Plus, OCZ Vertex 4, OCZ Agility 4 and Kingston HyperX 3K. To test the performance of the Plextor PX-256M6S, I ran a series of benchmarks using CrystalDiskMark 3.0.1, HD Tach RW 3.0.4.0, ATTO Disk Benchmark 2.46, AS SSD, HD Tune Pro 4.61, Anvil's Storage Utilities and Iometer. For the operating system, I installed a fresh copy of Windows 7 Enterprise. The computer came equipped with an Intel Core i5-2400 CPU, 4GB of DDR3 1333MHz memory, Seagate Barracuda 7200.12 ST3250312AS 250GB SATA 6 Gb/s hard drive, NVIDIA Quadro FX580 512MB PCIe graphics card and an Intel 82579-LM gigabit network card. The test system used in this review was an HP 8200 Elite.
