The SanDisk X400 1TB SSD Review

The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.
We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.
The X400's average data rate on The Destroyer places it clearly ahead of the other planar TLC drives and on par with the Crucial MX200.
The average service time for the X400 doesn't quite compete against the MLC drives, but it does put the X400 clearly ahead of the budget TLC drives.
The X400's latency outliers at the 10ms threshold again put it ahead of the budget drives but also clearly behind the MLC drives and the Samsung 850 EVO.
At the 100ms threshold for latency outliers most drives in this roundup score very close to each other, and the X400 is a little slower than average.
The X400's power usage over the course of The Destroyer is pretty good, especially for a TLC drive. Most of the faster drives sacrifice some efficiency.

Ugh, I can't edit my comment, come on.
