The Storage Networking Industry Association (SNIA), a working group made up of SSD, flash, and controller vendors, has a testing procedure that attempts to control as many of the variables inherent to SSDs as possible. SNIA’s Solid State Storage Performance Test Specification (SSS PTS) is a great resource for enterprise SSD testing. The procedure does not define what tests should be run, but rather the way in which they are run. This workflow is broken down into four parts:

  1. Purge: Purging puts the drive at a known starting point. For SSDs, this normally means Secure Erase.
  2. Workload-Independent Preconditioning: A prescribed workloadthat is unrelated to the test workload.
  3. Workload-Based Preconditioning: The actual test workload (4 KB random, 128 KB sequential, and so on), which pushes the drive towards a steady state.
  4. Steady State: The point at which the drive’s performance is no longer changing for the variable being tracked.

These steps are critical when testing SSDs. It’s incredibly easy to not fully condition the drive and still observe out-of-box behavior, which may lead one to think that it’s steady-state. These steps are also important when going between random and sequential writes.

For all performance tests in this review, the SSS PTS was followed to ensure accurate and repeatable results.

All tests employ random data, when available. Intel's SSD DC P3700 does not perform any compression prior to writing, so there is no difference in performance-based data patterns. We also chose to focus our comparisons on the Micron P320h and P420m, which are quite similar in performance and architecture. Both employ a proprietary driver that, while not NVMe, yields a very close approximation.

    A large heat sink on an SSD? This thing is too hot to touch!

    will this kind of ssd suffer from write wear out/reduce lifespan?

    In the 1st table on page 1, the "4k random write IOPS" are reversed :)

    (3500 scores highest, while the 3700 scores lowest)

    OCZ already went there and even made their own connector for providing more bandwith to SSD... just a shame that now Intel try to remove the carpet from beneath the feet of OCZ. Well, old tech is new tech.

    By the way, OCZ revodrive was priced similarly, I don't see that big fuzz from Toms here.

    "Intel's 2 TB model purportedly needs 650 LFM across the drive"

    What the hell is LFM?

    The active power consumption numbers on first table are wrong (I hope!) 35,000 watts active?

    Edit:
    It's not actually wrong it might just be my out of date browser I'm using in the office but for me the numbers aren't lining up correctly.

    Ah that makes sense now
