Just an update on this. 
I bought the 840 EVO SSD, be warned there seems to be a bug that needs to be fixed, The drive slows down over time so you won't notice an issue until later on down the road. 
This is what I just put together. 
 
 
Samsung 840 EVO Series MZ-7TE120BW 120GB 2.5in SATA III Internal SSD Single Unit Version
 
Cooler Master HAF 912 Combat ATX Mid Tower Case Black 4X5.25 1X3.5 6X3.5INT 4X2.5INT No PSU USB3.0
 
Cooler Master Extreme 2 Power Plus 725W ATX 12V Power Supply 20/24PIN 120mm Fan
 
Gigabyte Z97X-SOC ATX LGA1150 Z97 DDR3 PCI-E16 PCI-E8 XFIRE/SLI SATA3 USB3 HDMI DVI Motherboard
 
Patriot Viper 3 8GB 2X4GB PC3-12800 DDR3-1600 10-10-10-27 1.5V Dual Channel Memory Kit - Black Mamba
 
Intel Core i5 I5-4460 Haswell 3.2GHZ Processor LGA1150 6MB Cache 
 
I was originally just going to re build my original DAW using the Silverstone case and power supply. 
But I figured it's still working fine so leave it as a back up and ordered the case and PS. It was hard to find a case that had all my requirments and had to wait a wekk for it to come from back east...it's huge!! I never looked at the size specs in my quest for drive bays, quiet fans and front panel USB 3 etc. 
It's working perfectly after I hobbled all that stuff together, just doing the Updates. 
I ended up using my Windows 8.1 OS. Was simple to install from my DVD copy and click a link that stole $110 for a new licence. Scary how easy that was. All automatic, less than 2 minutes. Funny the DVD cost only $86 on sale and a download activation cost me $24 more. 
 
 

 Here's the link to the EVO fix, First is the explanation the second link is about the fix and if you scroll to the bottom there are links to the download.

Thanks for the info Johnny. I have the exact same SSD in my all purpose PC. And had a lot of work to get it going. So I was reluctant to out it in my music PC. It's still sitting up there on the desk waiting for me to put it in. Not sure if I will. I just didn't see a significant difference in my all purpose to justify putting it in my music PC.

I doubt you can buy a Samsung EVO which doesnt already ship with a fixed firmware.
And then there's Samsung Magician software, you get all updates with a single click, plus OS optimization, Drive Optimization and Benchmark, and other cool stuff! Its a must!

No this fix just came out October 14th. So I doubt any currant stock was "fixed" already. Mine wasn't. The firmware update ran just fine and then it runs a utility after re boot that takes up to an hour to  "fix" your data. Mine only took 10 minutes as I'm only at the OS level at this point. I'm waiting for all updates to run before moving to the software install phase. 
I'll say one thing, this is all working FAST! USB 3 loading from my external drive, and even the internet is super fast. Window 8 loads in 5-10 seconds to password screen. 
 
Anyhow the issue was one of slow access of OLD data. New data was not effected. So It might take a year before you would notice something wrong. I'll give Samsung credit for resolving the issue very quickly. Problem is, the fix is sort of hidden away and I would think unless you belong to a forum you won't know about the bug. And don't thank me Thank Rsinger for the post in the Sonar forum.  
I just changed this thread title so more people will get the message.

Oh so it's another thing. I thought i saw the exact same problem way back, maybe in another series.

My EVO is my sample drive.
Where do I run the exe file from?
Do I put on any drive? the C drive? Or must it run from the EVO itself?
TIA,

My two Intel SSDs are working fine after two years. Though if I were rebuilding from scratch I'd be inclined to consider 500Gb Samsungs for the audio drive. SSD byte-per-buck ratio is much better than a couple of years ago.

As for SSD over USB3, not sure I'd go that way. You should get some speed boost over a 7200 3.5" HDD but nothing like as much as connecting an SSD to the SATA bus. The bigger problem is that to work well and maintain their speed it is necessary for SSDs to be sent the TRIM command by the operating system. I've been researching external fast storage and as far as I can see USB does not support TRIM.

Which means that once the SSD gets to be around 1/2 full (or maybe less) it will suffer a huge drop in speed, especially for writes.

FWIW,
 
Connected to an Intel USB3 controller, you'd see all 520MB/Sec from a Samsung 840 EVO SSD.
An Intel USB3 controller (integrated into Z series chipsets) tops out sustaining ~550MB/Sec.
 
I've got a Samsung 840 EVO "Samples" drive that's over 90% full...
Sustains 500+MB/Sec on reads.

Hi Tom,
 
You have to install the utility (on the boot drive)... and run the application once installed.
Depending on what's on the SSD, it can take a few minutes (not instantaneous).

Using a SSD as boot drive:
The machine would boot faster... applications open up a little faster... and Windows navigation is a tiny bit "snappier".
 
Where SSD really shines is scenarios where you need large amounts of disk-streaming polyphony from advanced sample libraries.
ie:  If you're composing for video games (no time/budget for a real symphony)... and you're using 1200 notes of disk-streaming polyphony from Hollywood Strings/etc, you're forced to use (multiple) SSD.
 
A SSD is about 3 times the speed of a fast conventional HD.
