Micron M510DC (480GB) Enterprise SATA SSD Review
by Kristian Vättö on July 21, 2015 8:00 AM EST128KB Sequential Write
While most enterprise IO patterns are random by nature, there are use cases such as media streaming where sequential performance has a significant role. The sequential write test is a two-hour run with performance being measured during the last 500 seconds for accurate steady-state performance.
The M510DC offers mediocre sequential write performance, but making a direct comparison is hard given the different capacities. Random IO performance isn't as heavily impacted by the amount of NAND, but in sequential write performance the capacity plays a significant role (take the two 845DC EVOs as an example).
Queue depth scaling doesn't present any surprises. Nearly all drives reach maximum data rate at QD2, which is well below the average queue depth of a typical enterprise workload.
Unfortunately my script had a minor error in it and I don't have consistency to report. I've now fixed the script, but in order to deliver this review on a timely matter I decided to leave it out for now because retesting all drives would have taken an extra week or so.
The efficiency isn't admirable, but honestly only the 845DC PRO shines here thanks to the higher power efficiency of 3D NAND.

Bring on the 10TB SSDs. The 512GB-2TB models have lost all interest for me.thulasiram.valleru - Monday, August 10, 2015 - link
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.
