The SanDisk X400 1TB SSD Review
by Billy Tallis on May 6, 2016 9:00 AM ESTAnandTech Storage Bench - The Destroyer
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.

There`s 3.1 down there somewhere too.I`d like to have the source on your percentages though.

Looks like the 1TB Mushkin Reactor (MKNSSDRE1TB) is still the best value drive to beat. Nice to see TLC drives other than Evo's getting better though.hojnikb - Thursday, June 23, 2016 - link
there is also reactor LT, if you want 512GB.justkar4u - Wednesday, May 11, 2016 - link
@anandtech : Seriously ? You are trying to compare apples to oranges to grapes. You are comparing 3D NAND products with 2D NAND, MLC with TLC type products. Sandisk X400 should be compared with OCZ Trion and Crucial BX series. As you can see X400 is better than Crucial MX in some cases ! Samsung, OCZ vector, crucial MX should not even be there in comparison. With that said, clearly X400 is the winner in TLC segment.nobozos - Thursday, May 12, 2016 - link
It would sure be nice if you could include a graph in some (all?) of your charts that normalizes for cost. Raw performance is nice, but performance/$ is also very useful.Andre74 - Friday, May 27, 2016 - link
What's the deal with referring to "Power" both as W·h, and as W (but commenting on efficiency)?Efficiency would be energy consumed per byte read, for example. Effectiveness could be bytes read per second. Measuring power usage during operation tells you nothing of either efficiency or effectiveness, unless it's calculated as total energy.

"The Reactor is about $25 cheaper but only has a 3-year warranty and less than half the write endurance rating." Is this because of n-cache technique? MLC, TLC factors - Does it not make Mushkin a little better one?Endurance Rating
Mushkin Enhanced Reactor 1TB - 144TB
SanDisk X400 1TB - 320TB
Moreover SanDisk X400 is recommended for OEM unlike Mushkin which is targeted at consumer? Does it make a difference?
hojnikb - Thursday, June 23, 2016 - link
Thats just manufacturer rating. I'm sure unless Mushkin uses the crappiest MLC out there, that it will outlive sandisk x400 in terms of real world endurance.BimmerInd - Friday, June 24, 2016 - link
It says it uses Micron's NAND same as in Crucial's BX100. So which one should I choose?runasroot - Thursday, January 12, 2017 - link
I have a question: I know it states that it is 1024gb but is it a true 1024 or is it like something 960gb? I'm cloning a desktop with clonezilla and I need a 1tb ssd that is larger that 960GB to clone from disk to disk. <a href="https://wander.io">Wander</a>
