The Samsung 840 EVO mSATA SSD has done extremely well in the
HD Tune Pro 5 sequential reading test, and whilst there isn’t a large margin
between the top SSDs, the Samsung 840 EVO mSATA 1000GB is the third fastest in
this test.

ATTO disk benchmark

ATTO has become a standard tool for measuring the data
throughput of HDD and SSD. It measures the reading and writing performance,
using different file sizes and block sizes.

The reading speed results on the Samsung 840 EVO mSATA SSD are
extremely impressive, topping out at nearly 557 MB/s, and writing speed is
equally impressive topping out at nearly 536 MB/s.

Let’s find out how this compares with other recently tested
SSDs.

ATTO Reading performance

performance.


CrystalDiskMark 3.0

Crystal Disk Mark is quite a handy benchmarking application,
as it focuses on the file sizes that can cause a problem on a system drive.

As we can see from the above screenshot, sequential reading and
writing speeds are both very impressive, random reading and writing speeds at
low and high queue depths are outstanding.

AS SSD Benchmark

AS SSD benchmark is a benchmarking tool specifically
designed to test SSDs. The application tests sequential reading and writing
performance, 4K random reading and writing performance.

AS SSD benchmark also tests 4K threaded performance. This is
very exciting, as this test is the first available test that I am aware of,
that simulates how a PC operating system actually works. A modern PC and OS, such
as Windows 7/8 does not just run a single thread at a time, it runs many
threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads
simultaneously throughout the test. If this result is good, then you can be
pretty sure the drive will perform extremely well as a system drive.

After the tests complete, AS SSD benchmark derives a total
score for the drive being tested. This is based on all aspects of the test
results, and gives an indication of how the drive is performing overall.

Now let’s look at the result from the Samsung 840 EVO mSATA
SSD in the form of a screenshot. All our other comparison drives’ results are
presented in the form of a graph.

As we can see from the AS SSD test run, the Samsung 840 EVO
mSATA SSD has excellent reading performance, and writing performance is very
impressive, finishing this test in second place overall.

Summary:

The Samsung 840 EVO mSATA 1000GB SSD has performed extremely
well in the basic synthetic benchmarks. Random reading and writing performance
is very impressive. Sequential reading and writing performance is excellent.
