Thanks for the extremely quick response. Would you mind expanding on that?

If you can spare it, the more that you leave unallocated the better but the point of diminishing returns is fast after ~8%. 240GB drives already have ~16GB overprovisioned (6%) so you shouldn't have to worry about it and just use as much as you'd like especially if there aren't a crazy amount of writes going on.
but I continue to leave 80% free on all my SSDs.
I would allocate all of it, but leave at least 80% of the allocated space free of data.
Yep, sorry about that... ...20% free space.That has to be a typo, right?
LOL. Sorry about raking you over the coals on that one. Leaving 20% unused is a good strategy.
Even for that and to which I agree, I like my boot/system drives only half-full and I get antsy when used capacity is going over 75%.

Actually it is 20% waste. The SSD already has spare area. The flash is 256GB only 240GB is allocated by the firmware. For a home user, 16GB of spare area is typically enough.
Obviously you should have free room on a boot volume but there is little reason to leave 48GB unused.
My friend had a 30GB OCZ Agility SSD that I gave him, with Win7 64-bit on it. With only 3GB free, he was getting "pauses" with his system, because the SSD was constantly having to re-arrange and free up blocks to write to. Yes, even with the built-in "spare area".
So, sometimes, if you want maximum performance AND longevity from your SSD, it would be wise to over-provision the spare area somewhat.
If this was true, then TRIM wasn't working. Otherwise you claim make no sense, the firmware was poor on that drive or the drive was defective. The spare area is always free for the drive to clear. It is up to the firmware to actually do anything.
None - fill it up and partition it exactly like an HDD if you need to. Why pay 10x more per GB just so you can molly-coddle it?What is the proper amount of unallocated space to leave on an 240GB ssd running W7, with nothing very intensive on it. Only 49.5% used.
I can ditto Larry's friend's Agility performance degradation. Once I replaced it with a larger drive, I wiped the Agility and put it in my HTPC as the boot drive... with only 30% used capacity, it ran like my new Samsung 840Pro 256GB that replaced it (in real world use, not benchmarks, of course.) Not defective, not bad FW... just a very small SSD. I think the problem is more magnified on the smaller GB SSD vs the larger ones, for obvious reasons... As I understand it, some SSDs have more OP/replacement memory than others, I still wouldn't want to run even a modern big GB SSD at 95%.
I run a few hundred 100GB SSDs @ 100% utilization so can't tell what the defect is with your application. I certainly don't see "stuttering."
--edit--
I also have now for the heck of it gone through the firstr 4 pages of google for "ssd stutter" and all of the fixes have been "enable ACPI, Update drivers, Update BIOS/Firmware,replaced defective drive."
