Every generation of capacitors naturally is better than the previous one. That's called evolution or progress. Using these supercapacitors in SSD will improve their characteristics significantly. I use SSD in my PC and I can't wait to replace it for even faster one.

the best use of SupCaps is to reduce the size of the battery which is often governed by the peak current requirements of a circuit. rather than using supcaps as a replacement for batteries (which is not advisable unless the outage is short) it should be used to supplement on certain parameters like peak/burst outputs of power.
There are now 5000F capacitors out there with sub-milliohm ESR (IOXUS makes them). They are rated for 2.7V. Put a 2.4V zener in parallel across them to keep them from overcharging, and they can be ganged as far as the eye can see. It may take a while to trickle charge them (it will take a day and a half for a 100mA charger to do so; the current limit is to keep a 500mW 2% 2.4V zener from overheating if it carries all the current in a confined space), but they would make an ideal short term power storage.
For any facility that cannot have power shut down, they will keep power up long enough for backup generators to turn on and come on line.
@I_B_Green: Yes, leakage current is parameter of concern for replacing battery in RTC application. Many application requires one year or more retention duration. Supercap leakage current can work only up to few weeks.
And how do they compare on,leakage current?
not a good choice for ultra low power sleep wake systems.
Leakage a function of capacity, so trying to replace batteries for long duration backup not a good choice from efficiency standpoint.
excellent choice for agmenting a battery for high pulse low duration help.
Can decrease battery capacity needed.
cross over of battery and super cap leakage rates needs to be graphed and desiminated.
1)Regarding the supercap limitation of 2,5V and 2,75V maximum per cell mentioned in the article.
Vina Technology (korea) www.vina.co.kr launched a supercap with 3V from 3F to 600F.
2)Also a chinese company has a patent and is in the market a hybrid unit: Supercap Lithium battery (3,2V from 10Ah to 100Ah) can be check at http://www.cyliyuan.com/en/product3.asp
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
