Yes, the SSD itself is unlikely to be generating the heat. My guess is that the processors is heating up because the SSD is less of a bottleneck than my old HD. My questions is more about this situation rather than the device itself.
Got a tip for us?

What i am also trying to impress upon you is the SSD isn't active all that much.
- If your computer is hot already in the 20 seconds it takes to boot, then there's a problem.
- If the difference between itunes booting in .5 seconds compared to 2.5 seconds make the computer hot you have a problem.
The processor just doesn't pull off the ssd long enough to make a difference in how hot it gets.
If you're working with large video files, then i could see it. But not in regular usage.
Yes I am booting up my computer. Yes I am launching applications and yes my computer is much hotter than usual.
So I guess I have a problem right?
Well anyone that boots their computer obviously has a problem
Those were examples of how implausible it would be.
A computer can't "heat up" in 20 seconds. It takes time for heat to transfer from inside the processor to the shell of the computer.
If you're computer goes from cold to hot in the 20 second boot time i'd suggest you not use it honestly.....
EDIT:
Check the Activity Monitor like i already mentioned a couple times. It will tell you precisely what your processor is busy doing which is causing your heat.

Thank you for your assistance.
Check the activity monitor.
Click launchpad, CLick other, Click Activity Monitor.
Next sort the processes by "% cpu" so highest is at the top.
See what is using the processor that's causing it to heat up. Feel free to post a screen shot of the processes if you want.

I received my 512 SSD today. Installed it and restored from time machine backup. I am running 8gb ram on 13inch Early 2011 MBP.
She is running great! I now know why you guys say never going back to HDD!

Very slow shutdown times
I just installed this SSD yesterday, and I keep on having very slow shutdown times..around 20 seconds or more. It doesn't matter if I reopen the apps I had running or not. After I choose shutdown or restart, it will change to a grey screen with a spinning icon, then it will finally shut down. My boot times are quick, 10-15 seconds, and everything else is very quick.
I do have trim enabled.
I switched from the Kingston HyperX 3K to this Samsung drive, and everything but the shut down time has been much faster. The kingston drive would shutdown in about 5 seconds whether I reopened the apps or not.
Any suggestions?

Brace yourself!
Samsung SSDs series 840 are coming soon.

what is the difference between the pro and consumer? all i can see is TLC for 840 consumer and MLC for 840 Pro. im not sure what that means.
also it states an extra hour of battery can be added for most laptops!
In theory it should mean 3 times longer life than the consumer model...
Well it depends on what you're doing. As you can see on anandtech the idle power consumption is not much less compared to the 830 model. Your hard drive does idling around most of the time I guess, so 15-30 minutes are more realistic I think.
Wow epic thread! At the risk of a potentially redundant question:
I've been running an OWC 3G 240GB SSD in my Early 2008, last generation Black MacBook for a while. Unfortunately after the one year mark, the drive started acting up and I had to RMA it under warranty. Since OWC's Sandforce-based drives were not the best at running FileVault 2 at a blistering pace, I decided to take the opportunity to upgrade to a 256GB Samsung 830 that benchmarks much better with encrypted data. The replacement OWC SSD will go in my 2008 Mac Pro, where I don't use FileVault.
I've mostly been pleased with the Samsung 830 so far. First off, I installed it in a PC at work and checked for newer firmware. Didn't find any, so I went ahead and installed the Samsung 830 in my MacBook, installed a fresh copy of Lion, migrated my old apps and user account from my Time Machine backup, and was back up and running.
Everything's running well, except I've seen some occasional events where the MacBook completely hangs and is unresponsive to all input, except I can still move the cursor around. All applications are unresponsive. The cursor sometimes turns into a SPOD, sometimes remains a regular old pointer arrow. After a minute or so, the system snaps back to life as if nothing ever happened. This never happened with the OWC SSD. I guess it's possible there's a glitch between the Samsung's 6G interface and my BlackBook's SATA-1 bus. I need to dive into my system logs and see if I can find anything else.
Anybody seen this happen on their systems? Anything I should try? Just hoping to make this old black brick last a few months longer until Apple rolls out a 13" rMBP.

I found out what was holding my 830, VLC player till open, I don't know how but it was set to open at login, now that I fixed that shut down time is 2 seconds.
Where can I check my warranty expiration date? Seagate bought Samsung and when I try to enter in my Samsung 830 SNs into the Seagate website, it doesn't recognize them. Anyone know how to check?
The 840 has more over provisioning:
112 GiBi usable space, compared to 128GB NAND --> 16 GB/12.5% over provisioning
233 GB --> 256 GB --> 21 GB/9% op
466 GB --> 512 GB --> 46 GB/9% op
This is the way the want to ensure enough lifetime, but the 840 is for Notebook/Desktop users, so no servers or workstation use.

Seagate bought the hard drive division.
The solid state division is still SAMSUNG.
Try here to register your 830.
so.. i just finished the installation of the 830 ssd. tons of troubleshooting and a million google searches later its complete. speeds went from 70/70 to 380/460-70(lol, peaking on read, sick).
question is, is there something i should do right after the installation? how about the TRIM everyones talking about?
battery has been reduced significantly though... i guess its because i disabled spotlight and now its enabled again and doing its index
oh and btw... safari wont open, i just get this error message, whats up with that?

I have a Macbook Pro 5.5 (13" - mid-2009) and purchased the 64 GB variant. I formatted and installed the operating system via an external enclosure as the SSD was not recognized inside the laptop.
However, after installing the OS and being able to even boot via the enclosure (with the SSD), when placed inside the laptop it is unable to detect the SSD.
Can anyone provide me any insight? Could it be that the drive is incompatible? I was told by the store it would work for any Macbook Pro.
I am doing this because my stock HDD has died.

Can't really provide insight but it should work. I have the same laptop and installed a 512GB variant without issue.
I received my new Samsung 830 today and have it connected inside a Windows XP PC and with the Magician software installed but for the life of me I can't see how to enable TRIM using it... am I missing something?
Thanks for any help!
Thanks for any help!
If the OS does not support TRIM - which XP does not - the magician software has a manual garbage collection you can run - and schedule.
Fantastically enthusiastic and proud new owner of the 256GB model. Install went completely fine -- attached new SSD to my Early 2011 MBP 15" (w/ 8GB Crucial) via USB, fired up Disk Utility, initialized the SSD, and used Carbon Copy Cloner to migrate to the new drive. A couple of hours later, I powered down and received the only hiccup -- the system hung. After 5 minutes of waiting, I held the power button down -- guess I should have ejected the SSD beforehand. Anyway, I got the drives transplanted and the first boot with the new SSD was much slower than expected. So, I went into System Preferences > Startup Disk and 'blessed' the new drive. Much better! For comparison:
HD Write: 62 MB/s
HD Read: 55 MB/s
SSD Write: 390 MB/s
SSD Read: 473 MB/s
And I thought going from 4GB to 8GB was a worthy upgrade! I have been converted!
What's the current recommendation regarding GC vs. TRIM? I did run into one other small hiccup that's been reported earlier in the thread where my keyboard and touchpad became unresponsive for ~10-15 seconds. It seemed to coincide with Spotlight finishing up rebuilding its index, and I haven't experienced it since then.
