Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data. AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs.
Examining the different capacities of the Intel SSD 525 left to right, we can see that the Total Score increases significantly and, even a better example of how performance improves with capacity, is seen in the Copy Bench results. Let’s take a look at the smallest vs the largest first hand.

Looking at these benchmarks, the performance difference, at every level, can be observed. Looking at the Copy Bench results below renders a more realistic point of view. AS SSD Copy Bench is a very effective benchmark for measuring ‘true to life’ performance. Through creation of .ISO, Program and Game files, the entire of file is move from one place on the SSD to another, providing the total time of transfer and top transfer speed reached.

It is similar to you moving a movie, music or pictures to or from your system. The result of the 240GB 525 on the right is excellent with very short transfer duration and all speeds reaching the SATA 3 area. The result of the 30GB 525 on the left, however, displays that it would take significantly longer to move your data, as much as 7 times longer in the case of the .ISO!
ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)
You may not see this for long (and its definitely not common) but you get a free-bee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.
COMPRESSIBLE DATA TESTING
INCOMPRESSIBLE DATA TESTING
Due to space constraints, we have only displayed the Anvil results for the Intel SSD 525 240GB capacity as an opportunity to demonstrate how ATTO falls in line and confirms the results of benchmarks seen thus far. We can see that utilizing incompressible data samples provides better results and, in fact, the Score of 4353 is one of the highest we have seen with an mSATA SSD. The top chart also provides IOPS numbers of 87,094 that surpass the specification number of 80,000 IOPS.

Which brand and model of mSATA to SATA did Intel supply?
It is just a generic adapter with the Intel name on it and is not available for purchase that I am aware of.
That is all nice but Mushkin is shipping a 480 GB mSATA that will outperform any of the Intel drives.
Wanna buy my first ssd and I’ m going crazy with all those bench.
Which one would be better between an old samsung 830 64gb and an intel 525 30gb for my T420 with Ubuntu? – I already have a 500gb hdd in ultrabay for storage –
According to various sites benchmarks, the first one seems to have better performance in heavy/light workload 2011 write test, the second one is way better in desktop iometer 4k random write…
I bought the 90GB MSATA 525 SSD this on Ebay for only $8 to use it with this cool enclosure from Orico at Amazon. It is working perfectly fine and has not been used a lot, but it is weird how there is not so much information about the 90GB model. Although I also have a 2230 enclosure with a 256GB KIOXIA BG6 2230 NVME (from a laptop upgrade), this 90GB 525 MSATA SSD and enclosure is also good to use for projects and is much faster than a USB disk.
