Intel SSD6 670P NVMe M.2 SSD Review (2TB) – Unbelievable QLC Performance

CRYSTAL DISK BENCHMARK VER. 7.0.0 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

THROUGHPUT

IOPS

It was right about here that we realized that the Intel 670p was special.  To start, its listed performance for both throughout and IOPS is higher than spec but….that’s not it.  Look specifically at the RND4k Q1T1 (random low 4K read) result of 81MB/s.  That is just about as good as it gets for any similar SSD and that means visible speed recognition in things such as start times and gaming.

AS SSD BENCHMARK VER 1.9

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

 

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

AJA VIDEO SYSTEM DISK TEST

The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.

TxBENCH

TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.

  1. Hey there Les, thanks for the review. From the benchmarks you’ve posted this seems like a great drive, especially for a drive with QLC flash. I am concerned that the performance will drop significantly when the drive is full of data, because it uses QLC and it has a Silicon Motion controller, and Silicon Motion optimizes its controllers to have strong performance when empty. Do you have any performance benchmarks when the drive is full of data, or 80% / 90% full?

    • Thank you for your interest in our website and welcome. Unfortunately, we haven’t traditionally done fill testing and have no plans to do such for this SSD at this time. If something should change, we will amend the report accordingly.

  2. What is the reliability (in P/E cycles) of the NAND that Intel used for this drive?
