SanDisk X400 1TB SATA III SSD Review

TweakTown Rating: 93%Manufacturer: SanDisk



Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.





Compressible sequential read/write transfers max out at 554/514 MB/s. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. Maximum sequential read performance is achieved at a 4MB transfer size, maximum sequential write performance at 256KB transfers.


Sequential Write




The choppy write performance with data on our OS disk is typical of many of today's TLC-based SSDs.


Sequential Read




Read performance displays a nice performance curve, with stout small file performance.



Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.








Anvil's scoring gives a good indication of a drive's overall performance. The X400 returns a good overall score, third best of the drives in our test pool. The X400 displays the best read performance due in part to its excellent 4K QD1 IOPS of well over 10K. 10,000 IOPS at 4K QD1 is a very good indicator that the X400 will deliver good moderate workload performance.


(Anvil) Read IOPS through Queue Depth Scale




The X400 smokes the rest of the field at QD1-8.


(Anvil) Write IOPS through Queue Scale




QD1 performance is the most important metric, and the X400 delivers the goods at 4K QD1. However, all but the TRION 100 deliver higher write performance than the X400 at QD2-32.
