Micron M600 SSD Review (256GB/1TB)


SSD Testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise SSDs.  For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

Sean Webster Test Bench Update 1

This is an updated test bench and, as such, we would love to thank those who jumped in specifically to help the cause.  Key contributors to this build are our friends at ASUS for the motherboard and be quiet! for the PSU and cooling fans. Also, a big thank you to Thermaltake for the case. We have detailed all components in the table below and they are all linked should you wish to make a duplicate of our system as so many seem to do, or check out the price of any single component.  As always, we appreciate your support in any purchase through our links!


This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project. All of the components we use for testing and evaluation can be easily purchased at a relatively affordable price. The links provided below can assist in pricing, as well as availability for those of you who may find interest in our equipment.

PC CHASSIS: Thermaltake Urban T81
MOTHERBOARD: Asus Maximus VI Extreme
CPU: Intel Core i5-4670K
CPU COOLER: Thermalright Silver Arrow
POWER SUPPLY: be quiet! Dark Power Pro 10 850W
SYSTEM COOLING: be quiet! Silent Wings 2
MEMORY: G.Skill Ares DDR3-1866Mhz Memory


The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, and PCMark Vantage. In our reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

As we can see above in the Crystal Disk Info screenshots, the M600’s S.M.A.R.T. data covers a broad range. It shows us a working temperature sensor, a host write amount counter, as well as many other helpful drive health figures.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

ATTO shows us some very good initial results. The 256GB M600 reaches 563MB/s read and 511MB/s write speeds and the 1TB version reaches 533MB/s read and 515MB/s write speeds.

    I really hope Crucial brings DWA to their consumer line aswell someday 🙂

    New Samsung 850 Pro is rated for only 150 TBW with a bigger lithography and Vertical NAND technology. And it claims the best endurance ratings on the market. But 16 NM Micron MLC is rated for 400 TBW. 3 times more endurance than the Samsung 850 Pro V-NAND. I am only a curious reader and I can see that: We – consumers do not need “Pro” tags. We only need more affordable! and more endurable products. Micron M600 may be a bit slower than Samsung 850 Pro but it is three times more endurable. And it will be much cheaper than 850 PRO.

    Wow, I really thought I could use the m600 as laptop ssd, but with such bad and much worse than advertised idle power consumption I’ll think twice before buying it. Eagerly waiting for the mSATA review, but because the 2.5″ results are already that bad, I’ll most likely wait for an Samsung 850 EVO mSATA which will probably be more alike to the 840 evo mSATA 210mW active idle.

      I’m sorry, I had not enabled hipm and dipm support for the drives when I tested the idle power draw. I have gone back and enabled it and new, much better idle results have been found. The 256GB model sits around 55 milliwatts idle and the 1TB sits around 45 milliwatts idle. The new results have been added to the review.

    Hey Les. Anandtech also reviews the M600. But service time of the M600 is the worst of all SSD drives. Despite DWA?

      I make it a habit not to read through others reviews, but thanks and… I did take a read. Thanks. The beauty of independant reports is that one gets to make the best decision through several differing opinions.

    Sorry to go off here but when are we going to see 1TB PCIe m.2 solutions at 4x? Is 1TB possible?
