MyDigitalSSD BPX M.2 NVMe 480GB SSD Review
IOMeter Sequential and 4K Random Performance
IOMeter Sequential Performance
Legit Reviews is once again adding IOMeter v1.1.0 testing to our Solid-State Drive reviews as we feel that the canned benchmarks no longer show enough of the performance picture nor do they expose many of the heat issues that we are starting to encounter on M.2 PCIe SSDs and sustained write issues on TLC NAND based drives. We start out testing each drive with IOMeter, but first we prepare the drive. This is done by using Parted Magic to complete a full Secure Erase each and every drive. Next we use IOMeter to prefill the drive by performing the industry standard 128KB, aligned, sequential write workload across the entire drive for a period of 30 minutes. Once the drive is conditioned we run our saved sequential test profile that runs our 128KB test for one minute with a five second ramp time before each test. The queue depth is set to 32 as we feel with NVMe drives starting to come out that we need to increase our IO depth.
The 128KB Sequential Read/Write test is done primarily to make sure the drives we are testing meet or surpass the manufacturer specifications for sequential Read/Write performance. The MyDigitalSSD M.2 480GB drive is rated at 2.6GB/s read and 1.3GB/s write and we were able to get 2.8 GB/s read and 1.5 GB/s write when performing each test for a period of 1 minute. We are happy with these scores and they mostly line up with the Corsair Force and Patriot Hellfire.
IOMeter 4K Random Performance
When it comes to 4K Random Read/Write IOPS, the Corsair Force MP500 M.2 480GB PCIe SSD is rated at 150,000 IOPS for Random Write and 265,000 IOPS for Random Read. We got 240,000 IOPS for the 4K Random Writes and 236,000 IOPS for the Random Read IOPS and those are good scores. The 80/20 mixed workload test that we ran dropped the performance down to 180,000 IOPS, but that too is a solid score.
