AnandTech Storage Bench - The Destroyer

The Destroyer has been an essential part of our SSD test suite for nearly two years now. It was crafted to provide a benchmark for very IO intensive workloads, which is where you most often notice the difference between drives. It's not necessarily the most relevant test to an average user, but for anyone with a heavier IO workload The Destroyer should do a good job at characterizing performance. For full details of this test, please refer to this article.

The 2TB Pro appears to be marginally slower than the 1TB model, but honestly we are talking about a ~5% difference. As I mentioned on the previous page, managing more NAND requires more controller resources and since the MHX is fundamentally an MEX with a beefier DRAM controller, a tiny performance hit is normal and despite that the 2TB Pro and EVO are still the fastest SATA drives on the market.

There's an increase in >10ms IOs, which I suspect is again due to the higher performance variation caused by the additional management resources required by the extra NAND.

The 2TB Pro turns out to have better power efficiency than its 512GB sibling. Normally smaller drives are more efficient due to having less NAND drawing power, but it may very well be that Samsung has moved to a more power efficient process node for the MHX controller, which would explain the lower power consumption.

    with the 2TB drive they should be good up to 2-6PB of written data at least (the 150-300TB is for warranty purpose past that they will not cover it) the Pro drive would be recommended if you know you're going to be doing lots of writes as tends to keep on going till it fails with 0 errors (EVO does not bold as well under mass data loads when exceeding its endurance spec)

    In the worst case at 14nm with the 840 Pro they saw ~800TB of writing before they acted up. They should easily see more than that with 40nm MLC 3d nand. 300TB is great way to to beat everyone else at the warranted writes and still only offer a warranty that covers 10% on the low of its projected use allowance. The 2 TB version is probably good for damn near 10 PB of writes (could be a lot more not using a calculator to figure out its true longevity).

    since your average modern ssd will manage much more than 300tb anyways, upping the (guaranteed) durability from 150 to 300tb doesn't really take much and might as well be considered a marketing move. not that it's a bad development.

    Even without the 3D V-NAND tech, when Samsung upped the warranty to five years on their 850 EVOs (compared to 3-years on the 840 EVOs) and still kept prices competitive, I was sold on their drives. If a company backs any of this PC tech for five years (and even 10 years on the 850 PRO series!) or more, their on the short list for any of my builds.

    the length of their warranties sold me too. I've been recommending them to friends to. One of those friend's 840 Pro however has been having some problems, attempting to do an RMA, Samsung only said they'd send out a refurbished drive (and never an upgraded model). This has put quite a sour taste in my mouth with Samsung (sadly). I don't know if Intel or others are any better with their RMA SSDs, but I sure hope so.

    It's common practice to send out refurbs for RMA replacement. For items under 30 days old, sometimes you can get a new replacement, depends on the manufacturer.
    What do you mean by upgraded model? Did he want an 850Pro for his 840 or something?

    did a RMA recently and in the email there was a notice that said they give New units within 90 days of purchase as long as you provide the proof of purchase.

    To be fair, SanDisk did the 10 years thing first on the Extreme Pro; Samsung may just be responding to that. The number of drives returned for warranty, even among drives that actually fail, is likely extremely low.

    Hmm, already got a 1TB EVO... Chances are I'll find a better deal (GB/$) on a second one by the end of this year than on the 2TB. I wish these had been out for a while already, if it were $700 or less already I would've picked one up instead of the 1TB I got recently (for $340). Trying to ditch HDD for anything but backups, but it'll come down to how much storage my photography ends up gobbling thru the year.

    The article is wrong about 1TB drives not being around at $1,000 and above. There were plenty of those drives.
