AnandTech Storage Bench - The Destroyer

The Destroyer is an extremely long test replicating the access patterns of heavy desktop usage. A detailed breakdown can be found in this review. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.

We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.

The M6V falls in the middle of the pack for its capacity class, and again its performance is a little behind its sibling with the same controller.

The middling to poor latency results echo the poor write performance consistency, but these results are nothing too concerning for a client drive designed for a typical consumer workload.

The SM2246EN continues to deliver impressive power efficiency, though again the BX100 beats the M6V.

    I beg to differ. For 90% of all use cases, the performance difference of a pcie drive to a sata one will be minimal if not unnoticeable whereas the pcie one is a lot more expensive (for now - I don't see a technical reason for this, really). Whereas everybody probably agrees the performance difference from sata ssd to sata HD is definitely noticeable.
    Albeit this drive indeed doesn't really offer anything interesting. There's nothing wrong with that but that means it has to nearly exclusively compete based on price, which it currently does not.

    simply not true, having used an sm951 for 3 months now the performance increase over the 850 is absolutely noticeable from bootup to shutdown and everything in between. Reply

    According to techreport boot times are noticeably faster and general loading times are not.

    We're still just talking about a few seconds difference. Most people won't notice the difference between a boot time of 37 seconds and 33 seconds. What people will notice is the difference between *any* SSD and any regular HDD.

    Most consumers should just get the cheapest SSD at the highest capacity they can afford. The performance difference isn't enough to justify going with e.g. a higher-performance 250GB SSD over a slightly slower 500GB drive (which allows you to store more of your data on the SSD instead of your much slower HDD).

    Irony is, right now the 850 EVO is also one of the best value SSDs available. Atm I wouldn't choose anything else for mainstream use. Reply

    Even if this were true (which really depends on your workload - for common workloads it really isn't), that doesn't mean it'd be a good idea to pick between the extremely expensive PCIe solutions and the extremely slow HDD solutions - old fashioned SATA still commands the sweet spot.

    Perhaps not for much longer, of course :-).

    Also, try hotswapping a PCIe-card :) Reply

    M.2 doesn't support hotplug, but it's been part of PCIe forever and is supported by both the normal full size expansion card form factor and the U.2 connector. The problem is that consumer-class systems often don't bother to fully implement support for the feature, though obviously they support it on some level for the sake of ExpressCard and Thunderbolt.

    Not taking in consideration that you cannot add or replace (most) laptops HDD with PCI-Express versions, so you have to use a SATA drive forcefully ... Reply
