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

TSSDR TEST BENCH AND PROTOCOL

SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our Intel SSD6 670p PCIe 3 NVMe M.2 SSD testing today, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible, the CPU C states have been disabled, C1E support has been disabled, and Enhanced Intel SpeedStep Technology (EIST) has been disabled.

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, TxBench, PCMark 8, PCMark 10, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.

CRYSTAL DISK INFO VER. 8.11.2 X64

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Crystal Disk Info validates that our SSD is running in PCIe 3.0 x4 (four lane), and also that NVMe 1.4 protocol is in use.

ATTO DISK BENCHMARK VER. 3.05

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Read performance in this ATTO result is just a bit lower than specs, but nothing to concern ourselves with. Personally, the most important aspect of ATTO that I watch for is a steady progression in speed as the data sample size increases; it is the mark of a solid product.

  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?
