my suggestions are related to loading speed and not deck management, and all of those suggstions are ones which from personal experience have increased the performance of my machines.
your deck loading speed issue realy does seem to be a hardware issue and not software issue ( there also seems to be a correlation between slower loading on the mac than on the pc as highlighted in the other thread) you cannot expect 250 files to load instantly... its just not possible whatever software or hardware you use. this is a limitation of computer hardware which is why i sugested the work arounds - to decrease the stress on your machine.
using the same drive for your operating system and clips WILL make the loading time slower as it is being accessed for 2 different applications at the same time ( essetialy halving the possible data rate ) - this is the same for every software which plays back clips from a hard drive.
there is a thread on this foum which reccomends using an ssd drive, it includes statistics to demonstrate that using ssd is faster for clip loading

and here is an external site which compares ssd and disk based drives which also confirms much faster loading times with ssd

my own experience of using an external ssd drive connected via eSATA is very positive i had a noticable increase in loading speed over using the internal 7200 rpm drive on both of my pc laptops ( i run multiple layers of 1080p footage ) and over the 8 years i have been vjing, the last 4 of which i have been a full time vj travelling around the world i have noticed a marked improvement in computer performance as the technology has increased.
as suggested on various sites, it is advisable to research the ssd drive before purchasing as there is variation in performance ( in the same way that there is variaton in performance in disk based drives ) if you want to get as near to instant loading as possible, you do need to spend mony on extras... standard equipment will not suffice.
it is also worth noting that the spcifications you have listed from the resolume website are the MINIMUM specifications
