Micron M510DC (480GB) Enterprise SATA SSD Review
by Kristian Vättö on July 21, 2015 8:00 AM EST128KB Sequential Read
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).
Consistency wise the M510DC isn't very good either, especially compared to the EVOs with outstanding consistency.
The same goes for power efficiency where the EVOs are again more efficient than the M510DC.

The endurance rating is basically the warranty for the drive, so it's a quite practical measure. If the drive fails before exceeding the rating, then you are eligible for replacements.nils_ - Friday, July 24, 2015 - link
It's a bit pointless to have a warranty on DC hardware if you have to send in your broken drive to get a replacement, since you're supposed to destroy it.Kristian Vättö - Sunday, July 26, 2015 - link
I'm not sure how exactly enterprise warranties work, but I would expect them to be more flexible given that the customers often do business worth of at least hundreds of thousands of dollars. Besides, with encryption the data is safe even when sent to the manufacturer.toyotabedzrock - Wednesday, July 22, 2015 - link

The problem with the Samsung 845DC (EVO and Pro) is that it is already EOL.andjohn2000 - Wednesday, July 22, 2015 - link

Hi, Kristian.Long time reader, here (since '98, I think), shy poster, though.
I wonder if you guys would consider evaluating real-life endurance in enterprise SSDs. Much like this:

The problem with evaluating endurance, especially on enterprise drives, is that by the time we have any useful data to show the drives are already obsolete. A sample size of one isn't enough either for any statistical analysis, so to really test endurance in real world we would need our own mini data center with hundreds of drives to get sufficient amount of data.
