Idle Power Consumption
Since we truncate idle times to 25µs in our Storage Bench traces, they don't give a fully accurate picture of real world power consumption as idle power consumption is not taken properly into account. Hence I'm still reporting idle power consumption as a separate benchmark because it's one of the most critical metrics when it comes evaluating an SSD for mobile use.
Unfortunately I still don't have a way to test DevSleep power consumption due to lack of platform support, but my testbed supports HIPM+DIPM power commands (also referred to as Slumber power), so the results give a rather accurate picture of real-world idle power consumption.
We've already seen that the BX100 is super efficient under load and what makes the news even better is that it also has excellent power consumption in idle/slumber mode. The BX100 seems to be an ideal fit for a laptop with its efficient power characteristics.
TRIM Validation
The move from Windows 7 to 8.1 introduced some problems with the methodology we have previously used to test TRIM functionality, so I had to come up with a new way to test. I tested a couple of different methods, but ultimately I decided to go with the easiest one that can actually be used by anyone. The software is simply called trimcheck and it was made by a developer that goes by the name CyberShadow in GitHub.
Trimcheck tests TRIM by creating a small, unique file and then deleting it. Next the program will check whether the data is still accessible by reading the raw LBA locations. If the data that is returned by the drive is all zeros, it has received the TRIM command and TRIM is functional.
And TRIM works.

Wow, that validates all of the other reviews I've been reading about this drive. Great performance, great value, and no TLC NAND worries. I'm getting one for my new laptop.Uplink10 - Saturday, April 11, 2015 - link
If you want a great value you better wait for a few months (maybe more than a few) till 3D NAND drives are going to come out from SanDisk, Micron, Intel, Toshiba. Then Samsing will not be the only company with 3D NAND drives and prices will probably going to come down.Harry_Wild - Saturday, April 25, 2015 - link
Thanks for the info! I will wait it out to get the best 3D NAND drives.Hace - Friday, April 10, 2015 - link
I'm kinda surprised you didn't draw more attention to the 850 EVO as a competitor, which is neck-in-neck with pricing.digiguy - Friday, April 10, 2015 - link
Yes, similar value for the money, and definitely more than the 840 EVO....Kristian Vättö - Friday, April 10, 2015 - link
I have to admit that I totally overlooked the 850 EVO as I was kinda assuming that its price would be higher. I put this review together on a very short notice as Ryan couldn't get the MacBook review finished for today, hence my mistake of not paying enough attention to the prices (even though I updated the table today...). Anyway, I've updated the conclusion to take the 850 EVO into account because as you said, the pricing is very close and it does provide a little higher performance.Hulk - Friday, April 10, 2015 - link
While the 850EVO is definitely a competitor for the BX100 the fact that it uses TLC NAND vs. MLC for the BX100 is a big deal for many people who aren't as yet convinced the 850EVO won't be affected by the read issue that is still a problem with the 840EVO. I realize the cell size for the 850 EVO's 3D NAND is much greater but as I wrote above many people, myself included, don't see the need to roll the dice on the 850EVO when the BX100 will provide basically similar performance.just4U - Friday, April 10, 2015 - link
The 850Evo is $20-$50 more on all models here in Canada. Not sure what stateside or Euro Pricing is like.Margalus - Saturday, April 11, 2015 - link
I just bought a 1TB EVO for $350 on Amazon, USArepoman27 - Saturday, April 11, 2015 - link
Kristian, hopefully you'll be helping Ryan with that MacBook review by covering the NVMe(!) SSD it ships with in depth. Looks to be a PCIe 2.0 x4 connected device dubbed "AP0256H", so possibly a semi-custom Apple controller based on the Marvell 88SS1093.
