it all depends on what you want out of your PC, performance wise.....
I debated long and hard whether to remain using the regular platter type Hard Drives  to upgrading to the supposedly faster Western Digital Velociraptor 10,000 RPM Hard Drives to upgrading to a decent sized SSD ( 64 GB , 80 GB, 120 GB , 128 GB  range )
I decided to go with a particular manufacturer of SSD because the life span was spec'ed for min. of 5 Years.............. so my options and choices weighed out that it was worth the extreme increase in performance that I could be using for a basically guaranteed 5 years service life on the SSD
I had originally decided to bite the bullet and bought the 450 GB WD Velociraptor 6.0 GB/s SATA III , which performed damn near identical/equal to my hitachi 1 TB 7,200 RPM & hitachi 1.5 TB 7,200 RPM drive ..............which both of the hitachi's cost less together than the WD Velociraptor.......
well, I then bought a 128 GB SSD 6.0 GB/s SATA III  and it costs $5 less than that same WD Velociraptor....... but the performance is breathtaking
some SSD's  firmware / drivers  have had severe setbacks and plagued with problems, but their are a few out there that are damn near problem free and very stable
Delirium brings up a valid point, and it plagued me on my first time around.........  I film almost every flight, and films will eat up a Hard Drive's storage space very quickly.....
I seriously hope HTC ( Aces high ) will eventually give us an option of saving our films to our own desired folder / drive!  instead of the automatic films saved to films sub directory like it currently is....
all though, Aces High was like click the Icon , blink your eye, you are logged in....... no hesitation in going from clicking on n Arena to being in the Tower
no hesitation from pressing the PC Power Button to typing in your password to log on to your desktop ( If You Use a  Password to log in )........  I like to see what is loading and I do not use the startup logo screen, I want to quickly scan everything from controllers initializing to memory quick test to IRQ settings, etc....  so I had to initiate a 10 second pause in my boot up sequence in my BIOS........... without it I was instantly looking at my desktop login screen
Graphics programs loaded at the bat of an eye..... AutoCad loaded like I was clicking   notepad instead.........
an SSD is just another PC component.......... like a PSU  or a GPU  or your Memory ( hell an SSD is Memory to be honest........  it is Flash Memory DIMMs  stacked on to a controller card then inclosed in a case for the SATA type SSD's  anyways.....  some of the PCIe type SSD's are open/uncovered  controller cards with Memory DIMM's on them............ just like a video card
some people buy very cheap $30 dollar PSU's ( Power Supplys ) ........... while some people will buy good quality $199.00 PSU's....  <-----  same  scenario can be applied towards video cards,, sound cards,  hard drives,  PC Cases.....  Monitors, Joysticks/Game Controllers, Keyboards,  Mouses,  System Memory,  Motherboards......... etc.......
I look at SSD's  like I look at any other Computer Component these days.......  after experiencing the exceptional performance increaseover the old regular HD's
sorry........ I went on a rant there ......... hope some of this makes sense
