Final thoughts and the conclusion
A modern operating system such as Windows 8 rarely does one
thing at time; it processes hundreds of threads at once. Just take a look at
the processes and services that are running in task manager for an idea of how
much is going on, even with the PC idling at the desktop. When you start
running applications on top of this, the workload increases in line with the number
and type of applications you are running. It’s also fair to say that many of
these processes are already loaded into system RAM, but many are also loaded into
and unloaded from RAM to the system drive as and when they are required.
If we look at the 4 basic requirements for a really fast
SSD, they are as follows.
- Small file threaded performance needs to be high.
- Small random file performance needs to be high.
- Sequential read and write speeds need to be high.
- Fast access times.
The Samsung 840 EVO mSATA SSD series SSD has all of these attributes
in abundance, and feels very snappy in use as a system drive.
I have only had the Samsung 840 EVO mSATA SSD series SSD for
a few weeks, so it’s not possible to comment on the drive’s long term reliability.
What I can say is that during the testing period, the Samsung 840 EVO mSATA
1000GB has been 100% stable, and has caused no problems whatsoever.
The Samsung 840 EVO mSATA SSD is as “plug n play” as it
gets. There are no special tweaks needed other than simply making sure that
AHCI SATA mode is enabled in the system UEFI (BIOS), and installing the latest
Intel RST SATA drivers, if you want to get the best performance and
compatibility out of this SSD.
Let us summarise the most important positive and negative
- Silky smooth operation as a system drive.
- Excellent sequential reading and writing performance, even
at very low queue depths.
- Excellent 4K random writing performance, at low and high queue
- Outstanding 4k random reading performance at very low
- TRIM support under Windows 7 and Windows 8.
- Completely silent operation.
- Fast operating system start-up and shutdown times.
- Competitively priced.
- Excellent software bundle.
- Nothing to mention.
To sum up, this is what I would
As the only drive in an Ultrabook or laptop, the Samsung 840
EVO mSATA 1000GB SSD is hard to fault. It is very capable of running the
operating system, and launching the applications at lightning speed, plus with
932GB of storage space available, it’s pretty unlikely that an Ultrabook user
would require further storage space.
Rapid mode and the Samsung Magician software is the icing on
the cake. Rapid mode has proven to be very reliable, and does give the feeling
of a more responsive system. The self encryption feature also adds to the
appeal of the 840 EVO mSATA SSD, especially if this SSD does find itself
installed in an Ultrabook. If the worst should happen, and the Ultrabook is
stolen, you can at least rest easy that thief won’t be able to access your
data. That’s assuming of course that you enable the security feature in
As an SSD, the Samsung EVO mSATA SSD is just as fast as the
standalone 840 EVO SATA SSD, and as we have seen from the tests in this
article, you can quite easily install the 840 EVO mSATA in a desktop PC, by
either connecting it to a suitable mSATA slot, or by placing the 840 EVO mSATA
SSD in a suitable SATA to mSATA enclosure.
If I was to sum up this SSD in one sentence, it would read like
the following. "What I find amazing is that so much speed and storage
capacity is available in such a small package".
The Samsung 840 EVO mSATA SSD will be available soon, and is
expected to be priced just above the price of the standard 840 EVO SATA SSD.
I’ve heard approximately £10 more, but we will have to wait and see if this is
the case when the 840 EVO mSATA SSD becomes available for purchase.
The parting sentence is:
“The Samsung 840 EVO mSATA 1000GB is an outstanding SSD,
and during the testing period proved to be very stable”.
The editor rating is based on the following key factors.
- Stability (is the device stable?)
- Supplied accessories (what is included in the package)
