Intel 750 1.2TB NVMe PCIe SSD Review

Myce Sustainable Performance Test

Over the last few months I have been studying countless
analyzer traces of real computing workloads, and also developing a test that
would accurately emulate and measure how performance is sustained over a period
of time. For obvious reasons, it is not possible to test an SSD review sample
over several months before publishing a review. The solution was to condense
this down to a manageable test, that doesn’t take too long to run.

I will make it clear right from the outset that this is not
a torture test. Bringing any SSD to its knees is not helpful in the least, as I
for one would not use any SSD that had slowed down to crawl, just to prove a
point. The Myce Sustainable Performance test, I believe is a tough, but
sensible test pattern to use for measuring how an SSD will be behave once it’s pushed
hard over a period of time.

The test pattern is "workstation" based, and
closely emulates a typical video or graphics workstation environment. The
results are measured using the same hardware I use for the Myce Reality Suite
tests, however, the test data and measuring system use a different method.

The SSD is first filled to 80% of its stated capacity.
Adding to the data that is already there, the "Sustainable
Performance" test data is added. This test data is approximately 20GB is
size, so once this is added the SSD is pretty full.

The test is then run for a period of 20 minutes. 60
performance measurements are taken for every minute of the test, and an average
performance figure is generated after each minute. At the end of the test I
have 20 performance measurements which are then used to generate the graph
below.

The faster SSDs will obviously sustain more writes then the
slower SSDs. For the fastest SSD in this test, the test pattern generated 173GB
of writes, and 193GB of data was read from the SSD during the test.

When reading the graph, you should not pay too much
attention to which drive is the fastest, but instead look at the sustainable
performance curve of each SSD, as this is what this test is all about.

For the SSD that I am reviewing, I will also add a second
graph which looks at the result in more detail.

So let’s look at the results.

Detailed results for the
review drive

The Intel 750 NVMe 1.2TB SSD has exceptionally good
sustainable performance when pushed extremely hard. There is a slowdown, but
it’s only down by 8 MB/s from peak performance. I highly doubt anyone would be
able to notice this slowdown in the real world.
