The packaging for this is minimal but seems efficient. I ordered from Amazon and they put the drive (which comes in a package the size of a CD case) in a larger box with some padding.
As far as installing the hardware into my desktop it was super easy. Mounted and plugged it in and it was good to go.
After double-checking to see my BIOS was set to AHCI mode for my SATA ports, I popped my Win 7 DVD in the drive and restarted my computer for installation.
Windows recognized the drive just fine and after making the few selections necessary it started to install.
This was the fastest installation of Windows I've ever encountered. I wasn't timing it directly but I'm pretty sure it was completely done in about 20 minutes. That's from initial "Start Installation" button click until the final reset where it boots up and you can actually start using windows.
After that, installing programs seems to be slightly faster but not that much faster than normal.
Copying files is waaaay faster. I copied over 20GB of files from my old Win install so that I could format the drive and replace them. It copied them over within a few minutes. Copying them back to my spinning-disk drive took a bit longer of course.
===== Expectations and Performance =====
I bought this to transfer Win 7 Pro and my games (mainly GW2, Diablo III, and other similar games) over to for better performance. So far it has been markedly faster but not as mind-bogglingly fast as I had built it up to potentially be.
As far as Win 7 Pro goes, I did a fresh install and after all the updates it now loads in probably less than 30 seconds. This is the most beneficial thing for this SSD so far in my opinion. I'm also including the time it takes me to type in my password. (probably 5-8 seconds)
I've noticed that my games do load faster than they used to and if I'm transitioning between zones/levels/what-have-you with friends or others I am nearly always the first person to show up "on the other side."
Over all, I am loving the increase in speed for the little things. Windows boots fast, games load faster, it just feels faster all around.
====== Summary ======
I would highly recommend transitioning over to an SSD for anyone who does anything with intensive hard drive use.
As far as using this particular drive, that's up to you. The research I did showed that the Samsung 840 Pro Series was recommended over the 840 Series as it's a different type of memory that will allow for more writes.
Hope this was helpful and if you get this drive I hope you enjoy it as much as I am!
==== UPDATE June 2nd, 2015 ====
I still have this running flawlessly in my desktop computer. It has had Windows 8 on it for 6+ months now and hasn't given me any issues at all. It is still extremely fast and works fantastically.
I recently bought two more of these exact drives to replace me and my wife's laptop drives and those have worked wonderfully as well. Hers is running Mac OS X (It's a Macbook Pro) and mine is running Win 8.1. No issues on either of those either.

Much better drive than the Intel, moved that drive to my 2nd bay. I'm a power user, running VMware, Linux, Windows, etc., and the SSD really improves performance.
That has all changed and the future is here. While still a bottleneck, SSDs are miles beyond HDDs. As far as speed, these drives are to HDDs as HDDs are to floppy disks (at least that's what it seems like). Windows boots in 6 seconds flat. Open an application and it's there right then. This is, quite simply, the new biggest upgrade you can make to computer speed.
There are also some great utilities included.. the Samsung Data Migration tool being one of the best. It will allow you to migrate from your current drive to the SSD with just the click of a mouse.. you don't even have to shut Windows down during the migration, just a reboot at the end and you're on the SSD. The Samsung Magician is also a great tool. There are some rather complex settings that need to be made to the OS to get the SSD to run at its optimum and the Magician makes it a snap.. even for novice users. Magician also has a mode called RAPID which sets aside system memory for a disc cache.. which basically doubles the speed of your SSD, pushing the sequential I/Os to over 1000MBps! A word of warning: if you turn on RAPID, you SHOULD have a UPS because if the system crashes before the information in cache is flushed to disc, it is lost forever. Personally, it's a chance I take because the window of opportunity for such a crash is so small.
I personally use my Samsung SSD in my desktop, but it would shine even more in a laptop. Laptop drives are notoriously slow and power hungry while the SSD is fast and only uses a fraction of the power. Migrating would be a bit more difficult unless you had a second drive bay.. but you but an external SATA 3 to USB connector for a very reasonable price.
It should be noted that, as fast as these are, the numbers can be a bit misleading. Sure, they can pull 500MB/s doing sequential reads and writes, but that's not how computers usually work... it's the random I/O that we do the most. Now this drive screams at random I/O because there is no seek time (the time it takes the head on a HDD to get from one place to another), saving a LOT of time and making the drive many times faster, but not to the extent that you get from sequential I/O.. thus the adoption of IOPS (I/Os per second). In some ways it is a more accurate way to measure speed but when sequential I/O is measured in MBps and random I/O is measured in IOPS, you almost get into an apple vs. oranges thing. They do this because the random I/O speed in MBps of a SSD, while faster than an HDD, is not nearly dramatic as the difference in sequential speeds (more in the area of 3-4x faster as compared to up to 10x faster on sequential I/Os). Don't get caught up in this.. this drive is FAST!
Another "drawback" that these drives have (as you may have read in other reviews) is the hard limit on writes to the drive. What this boils down to is that each memory segment on the drive has about 1500 writes and then it's dead. This sounds worse than it is.. the drive is constantly trying to make sure that you don't use segments over until the rest have been used. The bottom line is that by the time this drive starts losing sectors to write limits, you'll want to replace it anyways because technology will have advanced so far.
This technology is only going to advance.. but it is far enough along to jump on the bandwagon. Put this in your computer and you actually won't believe your eyes.. and you WON'T regret it!
WELL worth the money (but even better on sale)!
ADDENDUM: You will probably need a 2 1/2" to 3 1/2" converter. Check your case to see how the drives mount! I have an Antec with slides for the drives and it will ONLY attach to the converter from the bottom. I bought the Silverstone Tek 3.5-Inch to 2 X 2.5-Inch Hard Drive HDD SSD Bay Converter, Silver (SDP08) to use with it because it was one of the few that I could tell for sure accepted bottom mounting. This is strictly case-dependent, so check your case!
