Taking a closer look at Samsung's lineup of 840 Evo solid state drives shows, there are not only 2.5 inch models but also mSATA cards with up to 1 Terabyte capacity. Today we're having a closer look at the 250 Gigabyte mSATA model and we're rather curious to find out what this piece of hardware is capable of.

One of the biggest
issues with the Samsung 840 (non Pro) was its sequential write performance of 130 Megabyte per second. Since
at this point Samsung just wasn't competitive at all, they really had to do something about this to boost this value into a region where it can compete with for example Crucials M500 SSD. Apart from that Samsung also boosted IOPS performance, when you compare the 840 Evo with the older 840 drives.
At this point you should really ask yourself what kind of sorcery is going on behind the scenes that Samsung was able to triple sequential write performance from one generation to
another. The key to success actually has a name: TurboWrite. That's what the new proprietary technology has been called and basically it is an algorithm, which has been implemented into the firmware of the 840 Evo's new MEX controller. TurboWrite can use a small portion of the DRAM chip, which sits next to the controller on the SSD's PCB and emulate SLC NAND flash. As soon as there are data transfers this emulated SLC cache acts as a high performance buffer. In other words, Samsung brought the concept of DRAM caching into the SSD controller, which massively boosts sequential write performance,
that used to be the achilles heel of the 840 Evo's predecessor.
Next to an improved controller you also get a reworked software suite from Samsung. The latest version of Magician offers lots of features and it's easy to use even for unexperienced users. It's also exactly this group of users which are being addressed by Samsung with all 840 Evo drives and another point where you can see this is the price. With the 840 Evo Samsung is now attacking everywhere and especially their price level in combination with TLC NAND flash is very aggressively chosen.

Conclusion
Announcement:
Despite the circumstance that the rating of a product is based on as many
objective facts as possible there are factors which can have an influence on a
rating after publication. Every autor may perceive data differently over time
whereas one possible reason for example is a deeper background knowledge or
understanding of certain processes. Certain unforseen market conditions as well
as changes have the potential to render a descision made at a certain point in
time obsolete.
The 840 Evo mSATA and the 840 Evo with in 2.5 inch form factor are basically the same drives. In this case we can expect the same level of performance as well as a similar bundle. Therefore it's no surprise that also the mSATA version of the 840 Evo is compatible with the latest version of Magician software suite. As we already wrote in our reviews on the 2.5 inch 840 Evo the latest version of Magican is very well done. It is easy to understand and use but still offers lot and lots of options for enthusiast grade users.
At the beginning of the this review we were talking about the fact that the
predecessor of the 840 Evo suffered low sequential write performance. This was
basically the achilles heel of the Samsung 840. Our test drive was able to perform with
324 MB/s
sequential write and 532 MB/s sequential read throughput. When it comes to 4K
IOPS we measured 99'500 IOPS regarding random read and 76'700 regarding random
write. Unfortunately sequential write performance could still be quite a bit higher. But when looking at random read as well as random write, then everything is perfectly well. Especially the fact, that this drives hits almost 100'000 IOPS when it comes to random reads, makes it really attractive from a performance persepective.
Other than jsut raw performance you should keep in mind, this drive is using TLC (3 Bit MLC) NAND Flash, which
featres a significantly lower program erase cycle count than 2 Bit MLC. In case
of read intense environments, such as desktop computing and home users, this will cause no issues at
all and Samsung is expecting very low RMA rates on this drive. But still you
shouldn't think about using this drive in a server where several
Terabytes are going to be written per day. In this case 3 Bit MLC is simply the
wrong choice.
Taking a closer look at the price we see, that this 250
Gigabyte drive costs 146 Euro these days. This makes the 840 Evo mSATA one of the cheapest mSATA drives available.
Recommendation
Should you be looking
for a solid 250 Gigabyte SSD, then the Samsung 840 Evo is a good choice.
