From everything I have read, Intel seems to be the best of any SSD manufacturer out there and their prices seem to reflect this. And what you have posted is all correct when it comes to the installation of the drive, but it is not complete. If you are installing the SSD in a desktop computer, you will want to power the system down and remove the power cord from the back of your PSU, then drain any remaining electricity that is in the motherboard by pressing the power button on the front (or top) of your case before you attach the SSD to the PSU and the motherboard. If you are installing the SSD in a laptop, you will want to remove the laptop's battery before installing the drive. Also, make sure that your motherboard's BIOS is updated to the latest version. If there is a firmware update available, you need to research the procedure that the manufacturer recommends for finding the drive's current version of firmware and how to flash the firmware to its latest revision, if necessary. Trim should be enabled by default, and you can check this in the Command Prompt if you want to. If your current Windows 7 installation was performed with the SATA HDD in anything besides AHCI mode, you will need to go into your Windows registry and change the msahci value from 3 to 0, reboot, and check to make sure that your SATA ports on the mobo are operating in AHCI mode in the BIOS. After installing the drive, updating the firmware, and installing Windows 7 (with the SSD as the only storage drive attached to the motherboard), you will want to install the latest chipset and video drivers first, then run the Windows Experience Index from the System Properties window (doing this will disable the automatic defragmentation in Windows 7). Note: If you are overclocking anything on your system, it is considered a good rule of thumb to reset everything back to stock defaults for good overall stability during the installation. If you are planning to utilize "sleep mode" on your system, you might want to do a little research and see if your SSD manufacturer has any known issues with sleep mode at it is implemented in your motherboard's power management settings (BSODs or the SSD not being recognized at all when bringing it out of sleep mode are just two that I have heard of). There are also some other tweaks that you can use to optimize the drive after installation, but you will have to check with your SSD manufacturer as to whether they recommend them or not. If you feel the need to benchmark your SSD after installation, know that most manufactuers will advise that you do so sparingly. As for which SSD would be more suited to the task, I would recommend getting the 120 GB version of the SSD as your OS will most likely take anywhere from 14.5 to 20 GB of your SSD's capacity (BTW, it is generally recommended that you do not use more than eighty percent of your SSD's capacity).
Thank you a lot for the very informative guide! When you say to update the firmware (the step after installing the drive) you are talking about the BIOS , right? Or the SSD. I've heard that sometime you have to update the firmware on the SSD. I figure before I plug the SSD in I'll upgrade the BIOS (if necessary) and then do all the steps that you have told me.
