Well, the name of your company implies that you are already familiar with Solid State Drives. The configuration you have installed Felipe, is close to optimal for good performance. Scenery folders are best stored and allocated from the Addon Scenery folder for organizational purposes. Mention was made of "C" drive; that suggestion rises from the heightened security state of Windows 10, which prevents modification of installed programs in the Program Files directories and since FSX is a collection of routines and executables, it often hangs, or worse, when attempted to be run from Program Files and C:\Program Files (x86),
if installed into W10.
On a single hard drive, take magnetic head motion into account to retrieve your data.
Ya, if you are calculating orbital dynamics in real time and orienting a return transmission, read/write head delay can be a real issue. One has a bit more leeway when loading simulator sceneries.
For those needing to catch up, hard drives are built like record players, the record is the data is on platter and the needle is the read/write head. The clicking whirring noise when you start a computer is the read/write heads gathering all the necessary data to launch the OS. If you drop a hard drive, it can be damaged in the same way as if you dropped a record player.
When installed on multiple partitions, any program might invoke more magnetic head movements than necessarsy, invoking useleass delay in retrieving dats.
The best storage for FSX is a SSD as this eliminates any delay caused by mechanical parts.
This is a very open statement that seems to be cautionary without providing anything quantitative. Anything could do almost anything, given the right conditions. I am imagining an array, where each mechanical hard drive stores one bit of data and I am challenging you to a race, bring as many SSD's as you'd like.
Further, a partition is only that. A 3 platter hard drive with 6 r/w heads can be formatted with 1 or 20 partitions, this does not change the ratio of storage space to availible r/w heads. Additionally, if you take a typical FSX installation and you break it up into two hard drives, now you have TWICE the r/w head transcription speed, thus
halving any potential r/w delay.
A more accurate statement might be: "When installed on multiple partitions, any program might fragment to the point that r/w delay is significant." the solution is NOT to to eliminate space into which fragmentation can spread, the solution for any configuration would be to limit fragmentation.
