1TB Class Performance Testing

Product Comparison

With two firmware revisions and four capacities to look at, the charts today belong the MyDigitalSSD Pro today. We look at the initial release firmware and the new 12.1 updates on the 240GB, 480GB, 960GB, and large 1920GB drives.

Sequential Read Performance

The new E12 12.1 firmware update fixes the queue depth 2 (QD) dip issue found in our testing for most capacities, but there is a new drop at QD4. We suspect this is mainly an issue with cache, the amount of time we test for, and the order we perform the test. The peak performance is virtually unchanged with sequential reads, but that changes in other areas as you will soon see.

Sequential Write Performance

All drive BPX Pro capacities over the 240GB see a sequential write performance increase with the largest on the 1920GB model.

Sustained Sequential Write Performance

Sustained writes increased for every capacity with the hard dip we found around 20% removed.

Random Read Performance

The random read results show higher peak performance, but that only comes at high queue depths. This allows E12 sellers my MyDigitalSSD and Corsair to advertise higher results, but under real-world conditions under consumer workloads, the increase is meaningless. The drives all lost a small amount of random read IOPSs at low queue depths.

The random write performance also increased at high queue depths for all capacities, but again that comes at the expense of low queue depth performance where consumer workloads run.

70% Read Sequential Performance

Moving over to mixed workloads, we start with sequential data with a 70% read workload. The peak performance is nearly the same between the two versions tested. The problem we spot is lower performance at QD4 with the latest release compared to the 11.1 release.

70% Read Random Performance

The random test with 70% reads show a regression at low queue depths as well but much higher peak performance. The increase comes at QD16 where MyDigitalSSD raised the ceiling before the random IOPS plateau, but that is well outside of the consumer workload window.
