It is amazing to see the advancements and the future possibilities.
Problem is that the manufacturers and customers don't know which way to turn.
Just look at sata express, nice idea at the time, but I don't see a range of storage drives with the interface for sale. Maybe because it has already been superseded. But motherboards have the interface. Admittedly why bother when we have drives like the SM951.
Now they are talking about at least another big leap forward in speed.
How much faster is necessary for most situations and general usage?
I would like to see a capacity increase. Given how small these things are becoming, we still have (what is now effectively ancient tech when considering Moores Law and how slow they are) HDDs because they have the big capacity. Imagine how many TBs worth of modules you could fit into a 3.5" case, even if you used slower msata type SSD modules? Or how many M.2 madules would fit into a 2.5" case?
They keep pushing the boundaries for SSD speed, but restrict us still to having HDD's for capacity.
And I hope they can deal with the heat produced in these new products, I have used both the XP941 and the SM951, and they both get very hot. So much so that I ended up putting big heatsinks onto them with fans blowing across to help cool them. Another review site has thermal photos of a Samsung XP941 and a Plextor PX-G256M6e that got to ridiculous temps (113 °C just making a copy of a bunch of ISO files - I am not sure if it is OK to put in a link, but if you request it I will). After talking to some engineers at various companies which produce cooling solutions, it has even been noticed by them during in-house testing, so we may have M.2 coolers for sale in the future (how about trying to water cool your M.2 :-) ).
But what I want to see capacity increases up to at least several TBs (I would prefer to see 5 to 10TB's) with existing technology, instead of constantly trying to ramp up speeds with small capacity drives.
Here is a final thought, how about your new phone having TB's of storage instead of just a few GB's (my phone has 64Gb native, but I have 5x 64GB and 1x 128GB micro SD cards I swap between).
