Micron 5100 MAX 960GB SATA Enterprise SSD Review

SNIA IOPS Test

IOPS performance will typically vary greatly depending on
the nature of the IO traffic, including the mixture of Read and Write
operations, and the mixture of Block Sizes (the size of the IO operation’s data
packet, also referred to as IO Size). This test is designed to benchmark the
IOPS performance profile, at a Queue Depth of 32, for random IO operations for
56 different combinations of Read/Write mix % and Block Sizes when in a Steady
State, which are of interest to most users.

All of the SNIA’s test specifications define a ‘required’
set of parameters that must be run for the test and then allow the operator to
elect to run additional tests with different parameters of their choice. It is
the mandatory test with the required parameters that we run. Note that all of
the mandatory SNIA tests must be conducted with fully random data

As previously mentioned, a key principle of SNIA testing is
to provide a consistent basis for comparing different solutions from different
manufacturers.

Here are the results –

Here you can see a visual confirmation that Steady State
Convergence was determined at the end of Round 5 (note that steady state
convergence is calculated from the 4K line).

Here is a 3D and tabular presentation of the results. Users
can simply refer to the grid to obtain the R/W mix and Block Size value of
interest.  For example, Online Transaction Processing applications
typically run at a Block Size of 8K and a Read/Write Mix of 65/35, and users
can quickly understand how the device might perform under Steady State for
these access characteristics.

You can see that the 4K 100% Read IOPS result is 74,708,
which is significantly less than Micron’s specification of 93,000. The 4K 100% Write
IOPS result is 68,481 which is also somewhat less than Micron’s top end specification
of 74,000. The shortfall is probably explained by our testing being conducted
through an HBA (which is surely a typical form of deployment for the majority
of enterprise users) rather than directly through a Motherboard’s integrated
SATA connection. 

The highest we have seen for an SATA drive prior to this was
for the Samsung SM863 480GB when we made an OS level additional OP of 80GB,
which then hit 66,742 IOPS for 4K 100% Writes.

For interest we present a comparison of the 4K 100% Writes
and Reads results with those of the other Enterprise SSDs we have tested –

The 4K 100% Write IOPS of 68,481 is the highest we have seen
for an SATA based drive – an outstanding result.
