The Samsung 970 EVO is a positive step forward for Samsung
and it is clearly very fast, having set new records in most of our standard
However, Samsung’s competitors are closing in with their new
products and the sort of clear lead that Samsung enjoyed in the 960 EVO/PRO era
is no longer apparent. In the coming weeks I will be publishing reviews for
two more of these competitors – the Corsair MP300, and the Toshiba OCZ RC100. Leaving
Intel’s Optane based solutions to the side for the moment, we are beginning to
see the same lack of differentiation between NVMe solutions that we have seen
with SATA solutions for some time.
So, I thought it would be worthwhile to draw out some key
factors to form a summarised view that perhaps enables readers to see the wood
for the trees as we go forward.
NVMe drives Comparison Summary
The summary includes the following factors:
- The best price for the drive that I tested, as found on
amazon.co.uk at the time of publishing (Samsung 970 EVO 1TB – £309, Adata
SX8200 480GB – £123.20) converted to a price per GB.
- Endurance – the amount of data that can be written to the
drive within a 5 year period and for the drive to remain in warranty, stated
as the number of GB that can be written per GB of the drive’s user capacity.
So, for example, the Samsung 970 EVO 1TB is warranted for 600TB of writes and
the GBs that can be written per GB of user capacity is 600,000 / 1,000 =
- The Sequential Writes and Reads and Random 4K Writes and
Reads results from our OakGate FOB Tests
- The PCmark8 ‘Real World’ Storage Benchmark score
- The Anvil Synthetic Benchmark score
The best result for each factor is highlighted in green.
Other drives will be added to the NVMe Comparison Summary as we move forward.
Some observations on the Comparison Summary to date –
The Samsung 970 EVO is winning in most of the performance
benchmarks, but the SX8200 hits back hard with sensational low queue depth
random results, which makes the SX8200 an excellent system drive.
It’s interesting to note that the difference in the PCMark8
Storage benchmark results is marginal and this suggests to me that the user
experience to be gained from each drive would be very similar – or to put it
another way I very much doubt that a user could tell the difference.
The Samsung 970 EVO has good endurance for a consumer drive
(To my knowledge, and curiously, Adata hasn’t stated an endurance level for the
There’s not much in the pricing but it is clear that Samsung
has lost any clear price advantage that they may have enjoyed in the past.
So, which drive would I choose? First thing to declare is
that I would be very happy with either. Forced to make a choice, I would
choose the SX8200 as a system/boot drive. Probably the best thing to do would
be to select the capacity that you want and then go with the best price per GB
you can find.
It’ll be interesting to see where things get to as we review
and add more drives to the comparison in the near future.
I found the Samsung 970 EVO 1TB listed on Amazon for GBP £309.00.
I am pleased to award the Samsung 970 EVO our highest rating
