Its subsequent pace, barely above 80MBps, was slower than a hard drive. The Crucial X8 Portable SSD’s long copy rate was good for the first 180GB or so, then it fell off the cliff. It’s over an hour, where the next-slowest drive took a little under 23 minutes. No, the enormously long dark-blue bar you see below is not a good thing. The Crucial X8 Portable SSD wrote at almost 600MBps for the first 190GB or so, then it sank to a rather sickly 80MBps for the rest of the test. Most external SSDs maintain at anywhere from 400MBps to 600MBps. We do it to test the limits of the drive’s caching techniques. Most users will never write this large a file, or this amount of data in a single sitting. The X8 Portable SSD’s 48GB copy test results (shown above) are highly competitive, nearly the equal of those turned in by SanDisk’s top-dog Extreme Portable Pro.Īnd then…there was the 450GB write test. However, as with the other portable USB SSD drives we’ve tested, real-life performance didn’t match the synthetic benchmark results. When on cache, as it was the vast majority of the time, the X8 is almost as fast as SanDisk’s Extreme Portable Pro. All the other CDM 6 numbers were on track as well.

The numbers in the chart above are very competitive, and indicate performance for relatively short 1GB read and write tasks. Longer bars are better.ĬrystalDiskMark 6 (shown above) ranked the X8 Portable SSD as basically equal to the competition.

IDGįor 1GB files, the Crucial X8 Portable SSD is as fast as the competition. More on that in a bit, and back to the good news in CrystalDiskMark 6 (see darkest bars below).

However, in the one test where the X8 Portable SSD fell short-the 450GB write test-it fell short by miles. Performanceįor the vast majority of our testing, the 1TB Crucial X8 Portable SSD performed like a champ. The X8 Portable SSD ships with a Type-C to Type-C cable, with a Type-C to Type-A adapter.
