HD Tune Pro
In this benchmark I am checking sequential reading speed.
With an average sequential reading speed of 522.6 MB/s the Samsung
850 Pro SSD shows an excellent turn of speed. Also worth noting are the incredibly
fast access times.
Let’s see how this compares to other recently tested SSDs in
the table below.
The Samsung 850 Pro 1000GB 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 850 Pro 1000GB is the twelfth fastest
in this test.
ATTO disk benchmark
ATTO has become a standard tool for measuring the data
throughput of HDDs and SSDs. It measures the reading and writing performance,
using different file sizes and block sizes.
The reading speed results on the Samsung 850 Pro 1000GB SSD are
extremely impressive, topping out at over 564 MB/s, and writing speed is
equally impressive topping out at over 535 MB/s.
Let’s find out how this compares with other recently tested
ATTO Reading performance
ATTO – Reading performance at various block sizes
The Samsung 850 Pro SSD is one of the fastest SSDs when
ATTO Writing performance
ATTO – Writing performance at various block sizes
The Samsung 850 Pro SSD shows excellent writing performance.
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, and random writing performance at low
and high queue depths is excellent.
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 850 Pro SSD in
the form of a screenshot. All our other comparison drives’ results are
presented in the form of a graph.
Samsung 850 Pro 1000GB SSD
As we can see from the AS SSD test run, the Samsung 850 Pro
SSD has excellent reading and writing performance, finishing this test in first
The Samsung 850 Pro 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 outstanding.
