My setup:

  • AMD Ryzen 5 2600 6-Core 3.4 GHz (3.9 GHz Max Boost) Processor
  • Zotac RTX 2060 Super 8GB GDDR6 Graphics
  • 16GB Crucial Ballistix Sport LT DDR4 3000 MHz Memory
  • 500GB Seagate BarraCuda Solid State Drive
  • Intel 660p Series M.2 2280 1TB (SSDPEKNW010T8X1)
  • Thermaltake H200 TG RGB Case
  • Wraith Stealth Cooler
  • Thermaltake 3x ARGB RING Fans and 1x Front 120mm Fan
  • ASRock B450M/AC w/ Dual Band 802.11ac Wi-Fi Motherboard
  • 550-Watt 80 Plus Bronze Power Supply
  • Windows 10 Home (64-bit)
I'm installing a software (1TB huge file) from executable file (setup.exe) on my M.2 drive to the same M.2 drive. Its taking about 1.5 hours.

When I look at the Task Manager for my m.2 drive, read/write speeds do not exceed 25MB/s. CPU is at 16%, memory 5.7/15/9GB. Disk 26%

Should this be much much faster than 25MB/s or am I missing something?

Any feedback is appreciated.

Thanks

The 660p has a dynamic cache, which will shrink as the SSD filles up.

You're installing 1TB onto a 1TB drive, your cache shrinks.... 660p, during larger file transfers, as the drive fills up, can slump to <100MB/s.

Now, 25MB/s seems quite extreme, but the slow down isn't unheard of.
