Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V7.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously.
Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.
The PCMark 10 Data Drive Benchmark has been designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.
The Data Drive Benchmark uses 3 traces, running 3 passes with each trace.
Trace 1. Copying 339 JPEG files, 2.37 GB in total, in to the target drive (write test).
Trace 2. Making a copy of the JPEG files (read-write test).
Trace 3. Copying the JPEG files to another drive (read test).
Lexar quote read speeds for the drive of up to 1,750MB/s but as the Professional CFexpress USB 3.1 card reader only supports speeds of up to 1,050MB/s we couldn’t get to that maximum figure. The best read scores we saw were 1,045MB/s in ATTO and a slightly faster 1,066MB/s in CrystalDiskMark 7.
The official write performance figure is up to 1,000MB/s. Using the ATTO benchmark we couldn’t get close to that figure at 677MB/s. However, when tested with CrystalDiskMark’s Sequential default test we saw a figure of 1,012MB/s, confirming the official performance figure.
