The Trim Enabler patches the following Kext-File
/System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage
which checks if the ssd is a 3rd-party or Apple Branded SSD:
you can also enable trim manually by looking for all 'Apple' occurrences in the file and patching them in a hex-editor or ...

If your Mac supports 10.7 or later, see the "Installing OS X on an external storage device" section in http://support.apple.com/kb/ht4718.
Open Disk Utility when started up normally. Select the SSD, open the Partition tab, set the partition layout to one partition, set the format to Mac OS Extended (Journaled), and press the Apply button.

Have a look at the CPU die micrographs and reviews in the press and all are singing the same tune:
modest CPU performance gains
significant overall power reductions
dramatically better GPU - competes with mid-range dedicated GPU where the 4000 level graphics were adequate at best and lagged behind it's era of mid-range GPU substantially in many cases.

The drives are provisioned with space set aside to handle garbage collection and bad block replacement. I'm sure it's possible to drive the create benchmarks where a measurable drop in performance is shown under certain conditions but I've used six different SSD's in three different MB/MBP and have never noticed a drop in performance even when the drives ...

I have a 2010 MBP 15" with two Seagate Momentus XT 750GB hybrid hdd's (Removed optical drive - OWC website) and is being used for music creation using Pro Tools. It gets so hot that you have to stop what you are doing sometimes for larger sessions and save and close. Turn everything off and reopen session. Definitely the hybrid drives causing the problem and ...

I had the same issue, the problem for me was that the bootcamp manager only allowed me to take up space from allocated partitions.
Go into Disk Utility, select your 500GB SSD and select the "Partition" tab.
Make sure that "Macintosh HD" is taking up all the 500GB.

Another thing that might help is resetting the NVRAM and/or the SMC (here: https://discussions.apple.com/thread/4550751?start=0&tstart=0). Also, disable trim. It doesn't help at all, newer SSD's like yours have built in firmware that do a better job than trim. It might actually shorten the life of your SSD if you keep trying to use it.

How long did you have TrimEnabler running? It will only help over time, when through deleting files the SSD knows that the file clusters are no longer needed.
You can try to enable it, create a very large file (that takes up a significant chunk of your free space) and then delete it.
cd /tmp
mkfile 10240m 10Gigfile
rm 10Gigfile

There are two factors at play here:
How is the storage drive connected to the CPU? (which bus and what else shares that bus)
How are the bare drives comparable for file access times?
For the jump from HDD to SSD - the bigger factor is the drive and not the bus. There are many benefits to having a drive internal, but benchmark speeds isn't a prime reason. ...

It's definitely worth going internal. Someone asked the question some time ago here and the conclusion was, that even with USB3 (which only the newest Macs have), the internal version is more than 50% faster.
USB3 external will probably still be faster than a regular 2.5" MacBook drive (assuming that you have a MacBook), maybe even with USB2, but with older ...

The real reason may be the fact, that the recovery partition is no longer there.
Have you tried the resize with diskutil command? (man diskutil look for the resizeVolume command). If nothing else, it might give you a different or better error message.
A repair on the volume might also help.
Also see this question.

Yes, I'm posting this from an 24" Alu (7,1 model) which uses a Corsair SSD. I'd assume it would be the same with Samsung. Trim can be enabled. Instructions are here (it will patch the kext driver for the SSD and worked fine for me).

I did this before and the partitions appear on the desktop like USB pen drives or other drives you plug in. The NTFS drive will be read-only (but this is the same as internally, unless you use an NTFS file system support program that can write to it).

You'll see drives like as it was internally, just with a different icon. You will even be able to boot from the external MacOS (press and hold alt-key when the system chimes on power-up), but this (boot from USB) will not work for Windows.
But the files will be accessible as before.

I installed a (Samsung) SSD into a late 2008 Aluminum MacBook, which worked fine.
Apple does not automatically support TRIM for drives that aren't their own, but it can be enabled, for instance with this app: http://www.groths.org/trim-enabler/
Worked for me, just needs to be re-enabled after every system software update.
And yes, my MacBook is now a lot ...

Yes, you will see a mounted drive for each existing partition on the existing internal drive.

This is probably similar to a horrific bug in the original firmware of my Crucial SSD (I think a different model, but I don't work on that machine anymore). After a certain number of hours—so the long uptime is relevant, but in a lifetime way—the drive would shut down every hour, after exactly 60 minutes. I assume this was some testing code that inexplicably ...

It is worth it since you'll have your fast drive connected internally. Only in the case where you're worried about being able to boot off another server quickly, backup/clone your Mini to that USB3 drive would I keep the SSD externally connected.
The decrease in reliability of SSD vs. HDD can be countered by an automated backup system. You are doing ...

YES, it's definitely worth it. With my setup, sustained transfer speeds were roughly 75% better using SATA, vs. USB3.
I tested both configurations using ZoneBench as follows:
SSD: 120GB OWC Mercury Electra 6G
Mac: Late 2012 Mac Mini, 2.6Ghz core i7, model ID Macmini6,2, 16GB RAM
Hot-Swap unit: StarTech USB3-to-SATA dock, model SATDOCK22U3S ver2
