Breaking The Specs Down:

We looked at the 1tb version of the Crucial X8. This SSD is truly fast. Exactly how fast? The box description says it gets up to 1050 megabits per second re-write speed. But, that reminds us of the Fiat Uno. It says on the speedometer it can get 160 kilometers per hour, and maybe it can if you are going downhill, with the windows tightly closed, and the doors duct taped shut. The point is, just because the box says it can do it, doesn’t necessarily mean that is how the product will actually perform. So, we put the device on CrystalDiskMark to stress test it as a benchmark to see how it did. Have a look at the results in the graphs below.

In the real world, sequential writing according to CrystalDiskMark, on average was 434 megabits per second. The average reading speed was 438 megabits per second. So yes, there could be a number of factors that skew those results. However, for everyday use, that is really fast! Not to mention this is running on the NVM Express 1.3.

What also makes the Crucial X8 really cool, is it’s small both in footprint and form factor. The heat output on CrystalDiscMark during a stress test where it was under load, heavy usage, and strain was only 37° Celsius. It’s highly unlikely that the temperature will get higher than that with everyday use. And, have we mentioned how nice it looks?

Using The SSD:

Crucial X8 CasingWhen we first plugged in, we noticed that it’s in exFAT format, which likes transferring big files. However, exFAT doesn’t like long file names. So, when we copied across a Steam library of 96 gigabytes, that took an hour and a half. Thinking that something must be wrong, we decided to delete that 96 gigabyte folder, which took 45 minutes. We were naturally disappointed. We actually thought the unit might be faulty because it just didn’t work like it should have. Then, we remembered, exFAT; likes large files, doesn’t like long file names. So, we reformatted into the NTFS System and re-copied that same Steam library folder – 96 gigabytes, 9 minutes!

If you are like us and you’ve had the trouble of re-installing your entire Steam library, you know… downloading 96 gigabytes AGAIN – especially if you don’t have fibre internet – not to be melodramatic but… Oh the pain! The crying! The sadness! If you have more than just Dota 2 and CSGO this SSD is a necessity. Yes, we are looking specifically at you, Red Dead Redemption 2… you know what you did!

If you are an Apple user, you know the trouble with getting more storage (again… pain, crying, sadness!) and the likelihood that you’re just not going to get it. But, the Crucial X8 swings all ways; we’re talking Mac OS, PS4, XBox and Windows.

Pros and Cons:

  • Competitive performance
  • Removable cable and USB-C to USB-A adapter included
  • Low heat output
  • Small form factor, and great design
  • Slow write speed after write cache fills
