256GB Class Performance Testing

Product Comparison

In this section, we compare the 128GB and 256GB Inland NVMe SSDs to popular 256GB class SSDs.

In most of the read centric tests, the 128GB Inland NVMe will keep pace with the larger 256GB model, but that will change in the write tests. Many companies chose to ignore the 128GB capacity starting in 2017, especially for NVMe products. In this section, we're not trying to compare the 128GB Inland NVMe to the other products but want to simply show its performance.

Sequential Read Performance

The smaller Inland NVMe drives trail the other drives in our sequential read test throughout the queue depth range.

Sequential Write Performance

The sequential write test allows us to see the performance gap between the 128GB and 256GB Inland NVMe SSDs. The larger drive has twice the number of NAND die and is able to leverage them in parallel writes to double the performance.

The sequential write test also shows how these products fall into different performance classes that is often closely associated with the cost. The Samsung 970 EVO rides high and is a premium SSD with a price to match. The SMI SM2262 drives, Adata and HP, come just under the Samsung. The 256GB Inland NVMe and MyDigitalSSD SBX trail the others and round out the premium, mainstream, and entry-level NVMe tiers.

The unicorn of the group is the MyDigitalSSD BPX with the older Phison E7 controller and Toshiba 15nm MLC flash. When this drive first came to market, it held an entry-level price but delivered mainstream to premium performance. Products like the BPX are why we keep such a close eye on the smaller companies like MyDigitalSSD and Inland Professional. You never know when these companies will release a product that shakes up the status quo.

Sustained Sequential Write Performance

The 256GB Inland NVMe shows nearly identical sustained write performance to the MyDigitalSSD SBX. The performance is in line with what we expect from the entry-level products.

Random Read Performance

The two smaller Inland NVMe drives both hover around the 10,000 random read IOPS mark at QD1.

The QD1 random writes are so high for all of the drives in the charts today that we can overlook the performance. This only plays a role in the mixed workloads in the age of very large high-speed SLC buffers. The buffers are so fast that many modern NVMe SSDs ship with higher random write specifications than random reads.

70% Read Sequential Performance

Reading and writing sequential data closes the performance gap between the drives. The 256GB Inland NVMe performs really well here and gets very close to the two SM2262 controlled drives. The main difference is the very low queue depth range where the other drives have a significant advantage.

The low-power controller in the Inland NVMe drives is a disadvantage in the random mixed workloads test. The MyDigitalSSD BPX quad-core, 8-channel controller paired with MLC flash follows the same performance curve between QD2 and 4. So, Inland made really good progress with less resources, but the drives fall well short of the MyDigitalSSD SBX that manages to break into the top performance tier with drives that cost quite a bit more.
