Sustained Write Performance & Temperatures

Corsair Force MP500 SSD

Triple-Level Cell  TLC NAND based SSDs perform usually quite well, but when you copy a large amount of data to the drive without and idle time you’ll often find a large drop in write speed. TLC NAND is great in applications where write operations are limited , but is usually not recommended for critical systems that have heavy write operations as they have lower endurance ratings than SLC or MLC NAND and of course sustained write performance isn’t stellar. In recent years drive manufactures have been figured out that by using  SLC or TLC treated as SLC as a cache they can keep the drives overall write performance high as long as the amount of data being written to the drive fits in the cache. If you overflow the cache, you are then writing directly to the TLC NAND and the write performance will drop down to that level. It should be noted that the SLC cache will clear once the drive idles, so this only impacts long writes that are many GB in size. This might not be a typical workload scenario for this ultra-value or mainstream drives, but still something worth pointing out!

Let’s take a look at the Corsair Force MP500 480GB M.2 NVMe drive to see how it handles sustained write scenarios.

Corsair Force MP500 Sustained Write Performance

The Corsair Force MP500 starts out at around 1420 MB/s sequential write speeds, but after 12 seconds (17GB of writes) the performance dropped roughly 100 MB/s and went down to around 1350 MB/s.  When you average the test results over the 45 second period the average speed is 1369 MB/s.

Here are some 45 second average sustained write speeds on recently tested drives:

  • Corsair Force MP500 480GB – 1369.39 MB/s
  • Patriot Hellfire M.2 480GB – 1226.38 MB/s
  • Samsung SSD 960 EVO 1TB – 1223.07 MB/s
  • Samsung SSD 850 EVO 500GB – 527.23 MB/s
  • Crucial MX300 750GB SSD – 522.4 MB/s
  • ADATA SU800 512GB SSD – 520.85 MB/s
  • Toshiba OCZ VX500 512GB SSD – 520.41 MB/s
  • Intel 600p 512GB – 427.295 MB/s
  • Toshiba OCZ Trion 150 480GB – 347.75 MB/s
  • Samsung SSD 960 EVO 250GB – 326.37 MB/s
  • WD Blue SSD 1TB – 314.81 MB/s
  • Kingston UV400 480GB – 267.04 MB/s
  • OCZ Trion 100 480GB – 192.19 MB/s
  • ADATA SP550 480GB SSD – 103.53 MB/s

Not bad performance as the Corsair Force MP500 is without a doubt one of the fastest SSDs around with regards to sequential write performance, but we planned on seeing that due to the high-end Phison controller and use of MLC NAND Flash.

MP500 Sustained Write Performance

When you take a look at extended sustained write performance you can see that see a couple major performance dips down to 600 MB/s, but for the most part the sustained write performance stays well above 1,300 MB/s.

Corsair Force MP500 Series Temperatures

MP500 Case Fan

A quick look at the drives temperatures showed that we were hitting 67C and that was with a 120mm case fan sitting directly over the Corsair Force MP500 480GB M.2 NVMe drive blowing cool air over it. Before we started the sustained write test we were bouncing around 29C to 35C on the drive at idle. We set the polling rate to 10 seconds for this test and you can see how the drive heats up in this test below.

Corsair Force MP500 Temperatures

Phison has told us before that the E7 controller is rated for use at up to 125C and that the temperature sensor is located on the controller itself and not externally like some other designs. Some might think that this drive is close to overheating as Corsair gives the operating temperature range for this series as being between 0° ~ 70°C, but that is for the room temperature and not for the device itself. Corsair let us know that thermal throttling is triggered on the Force MP500 series at 80C and then performance will be scaled back until the temperature is back under 80C.

Corsair Force MP500 Recovery Temps

Once the heavy load was completed it took just over a minute for the drive to recovery down to normal ‘idle’ operation temperatures. Keep in mind that this is  with a 120mm case fan blowing directly on the MP500 470GB SSD. This drive runs hot like the Patriot Hellfire and other drives we’ve tested using the the Phison 5007 controller, so this isn’t a drive that you’ll want to stick in a laptop with limited airflow. The good news is that the dual sided design will limit the mobile devices that it will fit into and that likely isn’t a bad thing due to the temperatures.

Let’s take a look at some common benchmarks!
