Crucial MX100 (256GB & 512GB) Review
by Kristian Vättö on June 2, 2014 3:00 PM ESTPerformance vs. Transfer Size
ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. Performance scaling appears to be identical to M550, which is a healthy upgrade from the M500 but still falls behind the 840 EVO in read performance.

Wow, 256Gbit dies! That would mean up to 2TB in a standard 2.5" SSD -- Crazy!hojnikb - Monday, June 2, 2014 - link
Actually one could fit 4TB into a standard 2.5" (or even 8GB when using 32 packages) but the problem is, as far as i can tell, no single controller can adress so much space.hojnikb - Monday, June 2, 2014 - link
*TB obviously :)extide - Monday, June 2, 2014 - link
Yeah but it's a chicken and egg thing I think. There seems to be a max price cap of about $600 for these SSD's, and so for 64gbit NAND that was ~512GB and 128Gbit NAND it is about 1TB. When they design a controller to exist during the lifetime of 256Gbit NAND there is a good chance that someone is actually going to make a 2TB drive because that much NAND would then fit inside that 'max price' so they will design the controller for that max amount. And in the same vein a contrller for the 128Gbit era would be 'OK' with a 1TB max.... if that makes sense, heh.hojnikb - Monday, June 2, 2014 - link
Also, there is already 2TBs drives out thre on the old 64Gbit flash :)danwat1234 - Monday, January 26, 2015 - link
Intel S3500 2TB exists, not sure if it works in laptops thoughfruitcrash - Wednesday, June 4, 2014 - link
It's not that you can't address it (for ONFI NAND you can use the Volume Select command), but that you can't have more than about 8 chips on a channel because of capacitive loading.extide - Monday, June 2, 2014 - link
NOTE: I am talking about the future NAND, NOT what is used in this drive.hojnikb - Monday, June 2, 2014 - link
Still, 256Gbit dies can can't help you much, if controller can't adress that much space. As i've said above, once could fit 4-8TB of flash, it's just isn't possible yet.hojnikb - Monday, June 2, 2014 - link
Any details on the 128GB version ?I've read somewhere, that it will be using the old 20nm flash...
