I see all of this hardware improving dramtically, video cards, mainbords, processors, memory..but when are the harddrives gonna catch up? I have noticed that the harddrive is becoming a big bottlenecking issue and just want to see if anyone knows about some next gen harddrives to come out within the next few years.

Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

and then there are Solid State Disks (SSD) but they are still not affordable for the end user

There's SAS hard drives sometime down the line, or Serial Attached SCSI as it's called. I think Maxtor achieved 3.5 Gbps (gigabits) sustained transfer in a demo run of the SAS drives. Of course, I'm pretty sure that those would cost an arm and a leg.

with how many drives attached to the HBA?
SAS drives and controllers should be available near the end of this year.
I've seen several SAS drives and haven't seen one sustain over 100MB/s yet. I think it's doubtful they achieved 3.5Gb/s sustained since the interface itself only supports 3.0Gb/s.
I did get excited during my testing with one of our drives when I saw it consistently sustaining 150MB/s... Then I noticed that this was a solid state prototype drive meant to only test the SAS interface and had only about 512MB of storage... Talk about a big letdown when I discovered that!
SAS drives are expected to not cost significantly more than a similar capacity and rotational speed U320 SCSI drive.
