Intel claim sequential read/write speeds up to 3230/1625MBps
and our test rig confirms that.
It is not quite as fast as Samsung’s 970 EVO Plus at 3536.2/3322.6MBps or the WD Black at 3740/3000MBps but a 2TB model
in these costs $648/679. Let’s just say that the use case for these is very specific.
In IOPS terms it achieves read/write
of 340000/275000 and has an endurance rating of 288 TBW.
It has two x 256MB Micron DDR4 chips
that act as a dual lane fast cache. The high-end Silicon Motion SM2262
controller (unusual for this price point) looks after data flushing in the event
of a power outage. The cache allows frequently used data to be sorted and organised
to read and write sequentially at the highest speed.
The only drawback is that the cache can be fairly easily saturated,
and this affects random read/write speeds for larger files. That is where the Samsung
970 Evo Plus and WD Black really shine.
