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.

    Maybe I missed it, but warranty information?
  • twizzlebizzle22 - Tuesday, July 21, 2015 - link

    Would there be warrenty information available for the same reason price wasn't?

    My question is how longevity is affected from 1-2 DWPD

    5 year or NAND wear out, whichever comes first.

    I whish to have also the tests for non enterprise SSDs.

    These drives are not meant for the mass consumer, but enthusiasts like to try, or at least know how enterprise hardware performs on common PCs.

    And is not the same to have "an opinion", even if valid, that actually knowing the experimental data.

    Somebody will answer that, obviously, enterprise SSDs have different performance and workload targets, but that is no reason to discard consumer tests.

    There is a big difference between actually knowing how they work, and just making an educated guess.

    Also, enterprise users need to know how common hardware performs on server environments, because sometimes is cost effective to use common hardware for enterprise.
    For example, Google used lots of common hardware on his servers, and that gave him a large advantage over older companies, with larger budgets.

    Also, server hardware tends to have large validation and life cycles, and that means that it tends to have obsolete hardware. Sometimes is reasonable to use cheaper hardware, which can fail, but also has lower costs of replacement, or other benefits.

    Agreed. Also, as prices drop SSDs will be making their way onto client OS VM servers; and those will mostly see amped up versions of client workloads on them.

    You say that, but I recently picked up two 800GB Intel DC S3500 SSDs for use in my desktop, since they were near enough to the 960-1TB consumer drives, but brought me the nice benefit of full power-loss protection, higher performance than the Crucal M500/M550/M600/MX200 (though I doubt i'll ever notice it), and at $300 each, were really not that far from the $275 I've seen the 960GB M500 go down to.

    It's also always interesting to see if the price differential for "DC" hardware is justified or if you're just paying up for the label.

    Any idea what those ridicluously large caps on the PCB are for? I would hope for better unexpected power failure recovery -- but didn't see anything in the article touting that as a feature.
  • extide - Tuesday, July 21, 2015 - link

    Yes that's what they are for, it mentions it on the first page.

    Your conclusion is based on the manufacturer's reported reliability rating, but you never tested it. Who's to say if this drive actually is more durable than it's competition? Or even a cheap consumer drive?

    I know that testing this would be impractical, but it's difficult to judge hardware based solely on the manufacturer's claims.
