TSSDR TEST BENCH AND PROTOCOL
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.
SYSTEM COMPONENTS
This Test Bench build was the result of some great relationships and purchase; our appreciation goes to those who jumped in specifically to help the cause. Key contributors to this build are our friends at ASRock for the motherboard and CPU and be quiet! for the PSU and cooling fans. Also, a big thank you to Thermaltake for the case and Kingston for the RAM. 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!

BENCHMARK SOFTWARE
The software in use 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, Iometer, PCMark Vantage, and PCMark 8. 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.
Crystal Disk Info shows that NCQ and TRIM are supported, however just as in our Mushkin Reactor review, DevSleep does not show as being supported even though the manufacturer states it is. In addition, there are several useful S.M.A.R.T. data values, such as a working temperature monitor and Total Host Reads and Writes counters.
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.
Our results with ATTO are very good. Both read and write meet specifications no problem. The maximum sequential read speed is 562MB/s while the maximum sequential write is 461MB/s. We can also see that based on the graph that read speeds are in the 500MB/s range for file sizes as small as 32KB in size.
If you’re after 1.8″ drives, it would make more sense (from price perspective) to just buy a msata to 1.8″ sata converter card . You can get them for a few dollars off ebay. Much cheaper than buying 800$+ part.
Otherwise its nice to see more manufacturers going away from sandforce to something more respectable like siliconmotion.
Whether 1TB mSATA product of 2bit MLC is cheaper than this?
In sandforce2281, it is not put out 1TB of capacity.
You have 840evo for 360€ using TLC.
Or if you for some reason cant have TLC (you would _really_ need a good reason not to take TLC) apperently there is a M6PRO msata, thats also 1TB (cant find it on their website, but i see it selling for 600€).
840Evo I will exclude from a short life.
MSATA of M6Pro is suspicious information of 1TB product.
Number basis of memory chips, 1TB in 2bit MLC will feel like difficult.
But if M6Pro mSATA 1TB can buy at 600 euros, I likely can rest assured prefer over there.
>Number basis of memory chips, 1TB in 2bit MLC will feel like difficult.
Its not. 256GB MLC packages (so 4 of them makes 1TB) are not that uncommon. 128Gbit dies and 16 of them in a single package is perfectly achieveable with MLC.
>840Evo I will exclude from a short life.
Where are you getting the idea, that 840evo has short life ?
>Where are you getting the idea, that 840evo has short life ?
I’m sorry.
The life was short, it’s a 840.
Certainly I was life test in the Japanese site.
Like 840Evo is, SMART value becomes trough by writing to 171TB position in 120GB. It’s much longer lasting likely to if 1TB.
At 1TB, you’re likely gonna get 1PB of writes, before you even reach smart at 0%. But even when you do reach 0%, its still gonna work just fine, because its just a predetermined value for segmentation purposes.
And you have to have a really good reason to write soo much data.
