The SSD Advantage
Whether you're refreshing an older laptop or trying to maximize the potential of the latest platform, SSDs provide substantial benefits over traditional hard drives.
Solid State Drives feature a non-mechanical design of NAND flash mounted to circuit boards, shock resistant up to 1500g. Hard disk drives consist of various moving parts making them susceptible to shock and damage.
SSDs have 100 times greater throughput and instantaneous access times for quicker boot-ups, faster file transfers, and overall snappier performance than hard drives. HDDs can only access the data faster the closer it is from the read/ write heads, while all parts of the SSD can be accessed at once.
Less Power Consumption, Silent Operation, and Lightweight
SSDs use significantly less wattage at peak load than hard disk drives--less than 2W versus 6W for an HDD--delivering longer battery life in notebooks, less power strain on system, and a cooler computing environment. With no moving parts, SSDs run virtually silent in your notebook or PC case to eliminate distracting noises during gaming or entertainment. And SSDs won't weigh down your laptop, netbook, or tablet PC when you're on the go.
SSDs run much cooler than hard disk drives...
...and much quieter, too.

First thing I did was to check the OCZ forums for more info on the latest firmware. OCZ has released the 1.5.2. After downloading the OCZ toolbox I was able to confirm that both drives came with this rev and so I am hopeful that this is a FW vs. a NAND quality issue. Here are the release notes of 1.5.2.
Improvements since version 1.5: Enhancements:
*Enhanced Data Integrity Algorithm
*Enhanced overall stability and compatibility with legacy chipsets
Note: After updating to v1.5.2, you cannot revert back to v1.5
Formatted the drive with 4k block size and ran an initial AS SSD Benchmark (note: drive is hooked to a SATA2 controller so performance will be much lower). Nothing unusual to report beside a fairly low 4k read IOPs 3577 vs 17106 for write. Using Windows 7 and latest AS SSD.
4 stars for the price/value of the drive and that it was not DOA as some others reported. I will update this review (and rating) if I run into any problems later (or better if it remains stable). It would be good to know if other see less or more problems with the 1.5.2 revision.

Since installing it, I've seen 360+ MB/s write and 330+ MB/s read speeds.
This is miles ahead of my old hard drive that came preinstalled on my MacBook Pro.
To install, you have two choices:
1)Clone your drive;
Copying the entire contents of your old hard drive over to the new SSD.
2)New installation if Windows or Mac OS X;
Installing your OS anew, and starting fresh.
How to do:
To clone your drive contents to the new SSD, follow the steps below:
-First, you'll need to format it to support your system. If you're using a Mac, open disk utility. If you're using a PC, sorry, look for help elsewhere.
-To properly format the drive, click on the SSD in the tab next to the window. Click on the partition tab and select one (1) partition. Name the drive whatever you want. Next, click on format. You'll want to choose 'Mac OS Extended (Journaled)'. Then, click on the 'options' tab and choose GUID Partition for Intel Macs or Apple Partition Map for PowerPC Macs.
-Click format, and you're done.
-Now you'll a cloning app. My favourite is 'SuperDuper!'.
If you have 'SuperDuper!', open the app and choose your primary hard drive under the 'copy from' tab, and the new SSD under the 'copy to' tab.
-Click 'copy' and wait for your contents to be transferred over. Speeds will vary depending in how much data there is on your drive.
-Once done, you can install it in your MacBook or desktop Mac.
To start anew, you'll want a fresh installation of your favourite OS.
To do this, follow the following steps;
-Install the SSD in your MacBook or desktop Mac.
Insert the disk or flash drive containing your OS.
If you want to create a bootable drive for Mac OS X, look at No. 3) below.
-Hold the Tab key on your Mac or PC keyboard, and choose the storage for your OS.
-Complete the installation process, and you're done!
3)Creating a bootable drive for Mac OS X.
Follow these steps:
-Download the latest version of Mac OS X from the Mac App Store. Windows is typically distributed through physical media.
-Quit the installation of Mac OS X, and locate the installer in the Finder.
-Right click on the icon, and click 'Show Package Contents'.
-Go to shared support, and find the disk image labeled 'InstallESD.dmg'
-Open Disk Utility, and drag the 'InstallESD.dmg' file to the side bar.
-Double click the file to mount it, then select your storage from the side bar, be it a disk or flash drive.
-Click the restore tab above, and drag the 'InstallESD.dmg' file to the blank 'restore' table.
-Drag the name of your bootable media to the 'restore to' table.
-Voila! You have your bootable drive!
Thru SATA III, it give 220MB/second for writing. Why should I pay 50% more for Samsung drives?
I installed SAP ECC on my notebook which took 2 hrs, but this installation took 10 hrs in normal hard disk which is what i wanted regardless of Samsung or ocz. If the life span is going to be good, it is the best ROI. Still cost of this SSD is half the value of my high end laptop(1). Windows 2008 with sql server 2008 boots in 10 seconds.
