Intel SSD 750 Series 1.2TB review

Is this the second coming for solid state storage?

Intel SSD 750 Series 1.2TB
The first NVMe drive is here and it's a bit quick...

And what is top speed? The peak sequential numbers from ATTO are unprecedented.

The reads were almost 2.7GB/s and the writes were a little over 1.3GB/s. Inevitably the average scores on the more testing AS SSD benchmark were lower, but still 2.1GB/s and 1.2GB/s respectively isn't bad.

There are some interesting scores when we get to the 4k random read/write performance though.

At 30MB/s, the 4k random read speed is nothing to write home about, but the write performance of 200MB/s is stunning. That's nearly twice as quick as the closest competing drive on that front.

Compare all that with the fastest PCIe drive we've previously tested, the Samsung XP941, and you can see where the AHCI protocol is holding things back. Its 4k write performance is a quarter what the SSD 750 is capable of and the sequential performance is also lagging behind too.

It's not just in the synthetic tests where the SSD 750 shows its speed though.

Our real-world tests also have the Intel drive coming out on top, completing our 30GB Steam folder copy in two minutes flat. We noted its peak speed during transfer of around 750MB/s. That's mega quick.

We're all about consistency too and this new NVMe drive shows no problems there either, remaining at a pretty constant speed throughout the heavy PCMark 8 extended storage tests.

It wasn't consistently as quick as the PCIe Samsung drive during its PCMark testing, however.
