The SanDisk X400 1TB SSD Review

AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.

The scores on the Light test are not spread as widely as for the more intense ATSB tests, and the SLC caching capabilities of several of the drives come in handy. The X400's average data rate puts it in the middle of the pack, but its good full-drive performance distinguishes it from the other planar TLC drives and makes it tied against several MLC drives.

The average service time of the X400 is slightly worse than average for this bunch of drives, and it isn't able to score a clear win against any MLC drives on this metric.

The latency outliers above 10ms highlight the planar TLC drives as slower than most MLC drives, but the X400 doesn't do a particularly bad job of keeping latency low.

Once again the X400 comes in third for overall power efficiency (almost tied for second place), and this time there is a fairly clear gap between it and fourth place.
