Intel SSD 660P M.2 NVMe SSD Review (1TB)


HD Tune is a Hard Disk Utility with many functions from error checking, health testing (S.M.A.R.T.), and of course benchmarking. To build upon our real world write test we also looked to see where the write speeds leveled off to by using HD Tune Pro. If SLC caching is being utilized, this test will typically show it.

In HDTune we were able to write over 130GB of data before the drive’s write speed tanked. At that point, it averaged just 100MB/s of throughput.


With Intel’s latest 64L 3D QLC NAND flash on the market, we don’t believe it is the end of days as many fear. Instead, we look forward to what new products await us in the coming months. Today, we see a glimpse of how things will turn out.

While Intel has faced many challenges in developing and integrating their new QLC NAND into their latest product, they have ensured that it will meet and exceed the hopes and demands of the many consumers looking to buy it. The Intel SSD 660p is an impressive SSD. It may be small, but it sure does pack a punch.

Throughput figures of 1.8GB/s and the ability to deliver up to 220K IOPS read and write paint only one part of the 660p’s picture. As we saw in PCMark 8, the 660p was able to keep up with many of the mainstream performance options in the market, and during our 30GB transfer, it wrote the files at a rate of over 1.3GB/s, proving it is no slouch when it comes to large sequential write workloads. As well, it did so while consuming little power and it ranked near the top of our efficiency chart.


With MSRPs that reflect $0.20 per GB, the Intel 660p is one of the best values out. Sure, it doesn’t have the absolute best performance, nor quite as much endurance as TLC and MLC based SSDs, but considering its price to performance ratio and the fact that it supports AES 256-bit encryption and comes with a 5-year warranty, it’s hard to ignore. If you have been considering a SATA based SSD or even another PCIe based NVMe SSD for your next build, be sure to check this one out first. We award it our top value award, we couldn’t recommend it more.

QLC Brings Value

While many are skeptical about QLC memory, we assure you that Intel has done a bang up job in creating the Intel SSD 600p. It boasts some very good performance results and comes with a 5-year warranty and AES 256-bit hardware encryption support. At $0.20 per GB, it is a great buy for most. Be warned though, if you need a lot of write endurance, don't skimp out. With 200TBW of endurance, our 1TB sample only has 1/6th the endurance of the 970 PRO and 1/3rd the endurance of most mainstream NVMe SSDs.

  1. will the Intel 660p Series M.2 2280 2TB PCI-Express 3.0 x4 3D NAND Internal Solid State Drive actually work on an ryzen 2700 AMD AM4 motherboard something like the MSI x470 gaming Plus???

  2. these drives are junk, don’t bother. Buy cheap, buy twice. A crucial or Sandisk SATA SSD can be had for similar money and they at least write at around 450MB/sec sustained !
    I purchased 2 of these 1TB 660p drives to upgrade some old machines. When I started to copy the data over from a 7 year old HDD which is around 650GB, windows was telling me it would take around a day to copy !. WTF the 7 year old HDD is actually faster an NVMe drive as the HDD can at least write at around 160MB/sec. This level of performance is simply shocking in 2019. This drive may be ok for office use, but i’m going to try and return these as not fit for purpose.
