512GB Class Performance Testing

Product Comparison

A few of the same names carry over to the 512GB class testing. We've included the original BPX and the entry-level SBX to get a strong comparison between the three. The Intel 760p joins the party but is another drive with the SMI SM2262 controller.

Sequential Read Performance

The QD 2 and 4 sequential dip carries over to the 512GB class. This is more of an issue with our test script and not a problem with the drive. On the high-end, the BPX Pro achieves just under 3,500 MB/s, and the QD1 performance is actually higher than every other drive in the charts today.

Sequential Write Performance

We nearly hit MyDigitalSSD's claimed 2,100 MB/s sequential write speed with the 480GB BPX Pro without using more than one CPU manager. The drive trails the Samsung 970 EVO in this burst test by close to 500 MB/s.

Sustained Sequential Write Performance

The sustained sequential write performance is very strong. We measured right around 1,900 MB/s with a single thread transfer.

Random Read Performance

The 480GB drive also delivers just over 13,000 random read IOPS at QD1 like the larger 960GB. The HP EX920 and Adata SX8200 both lose some performance in this test compared to the larger capacity versions. The 480GB BPX Pro is very close to the SX8200 with less than 900 IOPS difference.

You will notice the MyDigtalSSD SBX shows superior random write performance compared to all of the other drives. We thought we updated all of the drives with new tests running the Spectre and Meltdown patches but missed the SBX. The test shows how the patches hurt write performance at high queue depths. We decided to leave the SBX numbers as is for this review since it's not a serious contender to the new BPX Pro premium SSD.

The BPX Pro shows strong random write performance at low queue depths. The series leads all of the comparison products before they all hit the Spectre / Meltdown brick wall that limits performance at higher queue depths.

70% Read Sequential Performance

We said in the sequential read test that we are not too concerned with the dip at QD2 and 4 because it doesn't show up in any other test. That also includes the same test perimeters in other software.

It also doesn't show up in the mixed workload tests with 70% read sequential data. The 480GB BPX Pro walks away from the other drives in this test, and there is significant distance in the important QD 4 to 8 range.

The random mixed performance test shows performance that is more subdued but it sits right in the middle of the three SM2262 controller drives.
