128KB Sequential Read

128KB Sequential Read (QD32) Performance

Given that the M510DC is supposed to be a read-centric drive, the sequential read performance is quite poor. The performance is by the spec, so it seems like it's a limitation in the firmware design itself. 

The scaling of Samsung drives is pleasant to watch, but the others not so much. I'm actually a little surprised by how poor the sequential read performance is, but it could simply be a matter of random IO optimization (but still, Samsung delivers in both random and sequential IO). 

128KB Sequential Read (QD32) Consistency

Consistency wise the M510DC isn't very good either, especially compared to the EVOs with outstanding consistency. 

128KB Sequential Read (QD32) Efficiency

The same goes for power efficiency where the EVOs are again more efficient than the M510DC.

    Bring on the 10TB SSDs. The 512GB-2TB models have lost all interest for me.

    In 4KB IOPS category, Samsung beats against most of its competitors and I am surprised no SSD delivers the speed in category 4KB read and writes as this company with this price range. Any body has a reasonable answer. I am not sure whether in house design and manufacturing of components made it possible for Samsung to achieve the difference.
