Mushkin Atlas 240GB mSATA SSD Review – Top Performance at an Unbeatable Price

ATTO DISK BENCHMARK VER. 2.46

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.

Performance result highs of 556MB/s read and 531MB/s write are some of the highest we have seen yet and meet manufacturer specifications.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.  We have provided compressible (oFill) results on the left with incompressible (random data) results on the right.

The overall performance of both benchmarks is great but, in examining the right result while testing in incompressible data, the high sequential and 512k write result might be just a bit low. The 4k random write result of 110MB/s is the highest we have seen yet in a mSATA SSD and definitely in the top 3 of all typical form factor SSDs we have looked at.  Such a result could easily see the Atlas top out in its testing with PCMark Vantage HDD Suite.

AS SSD BENCHMARK VER 1.6

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. Transfer speeds are displayed on the left with IOPS results on the right.

AS SSD once again confirms some great high sequential read performance, however, once again the write performance is a bit low and the 4k random write has dropped down just over 30MB/s.  When we followed through with AS SSD Copy Bench testing, the result was one of the best we had seen yet with all three transfer speeds being in the 6Gbps zone.

Any reason that Anvil RC2 and Intel RST 11.2.0.1006 are not being used in the benchmarking?

No reason… we change our systems quite often and test with a number of different versions. There is no appreciable difference.

What’s your opinion on the differences between this Mushkin Atlas 240GB and the Crucial/Micron M4 256GB mSATA especially with the current price difference?

Les@TheSSDReview

What differences would you speak? Crucial has had a great show with thr Marvell controller and, for the typical user experience, there is no difference at all. The visible difference will only be see with specific tasks that need the speed for incompressible file transfers.

which one do you recommend on mSATA lenovo Y480, for a reliable OS drive?

Mushkin Atlas 240GB vs Crucial m4 256GB mSATA

Both of these drives are stellar and I would be hard pressed to choose between the two. There is something worth watching closely however and that is the fact that SandForce has JUST announced their release of enhancements to the SF-2281 processor that will significantly improve battery life of laptops up to as much as an hour. Now, if that were to filter into product already on the market which we don’t know about at all, that might be a key factor in my choice.

Indeed, i remember seeing something like Mushkin Enhanced Atlas Series on newegg, does the enhanced atlas refer to the enhancements of the SF-2281 processor ?

Les@TheSSDReview

The Atlas, nor any other SF SSD, has the newly announced enhancements as of yet.

Any idea when those enhancements will be hitting the shelves?

Hello there,
First thank’s for those great reviews!! actually reading this from Paris, the matter is there is not a lot of choice here yet for a 256gb msata. The only one we can get on a french website is the Crucial M4. My Question is do you think the M4 is compatible with a toshiba portege Z930 ?
Thank’s in advance!

Les@TheSSDReview

That SSD will work perfectly in that system! I have the Z830 in use nd m very familiar with Toshiba Ultras.

Anyone know if this is compatible with the Samsung S9’s? Specifically the 13.3…??

Of course it is.
