I have to say I was hesitant in ordering another PNY product after having some real issues with some flash drives I've ordered from them recently. But for the great price of $39.99 for a 120gb SSD, I couldn't pass it up. And I'm glad I took a chance on this SSD because on my computer it is fast, especially for an entry level SSD. And it's not until I started using an SSD on an everyday basis that I began to realize how slow a regular HDD is in comparison. Everything that's on the SSD like your OS, programs and apps open up instantly and the boot/shut down times are unreal. Now for me, a 120gb SSD is more than enough for my needs since I'm not a serious gamer and I really just wanted to put my OS and most of the programs I use on a regular basis on it and maybe the occasional game or two that I may be playing at the moment. But, with that said, here's some advice that might help you make up your mind if you're considering between a 120gb or a 240gb SSD. My 120gb came with 105gb and of that 98gb was usable and my Windows 10 Home 64bit OS took up 29gb, plus another 10gb for Photoshop, Firefox, Chrome, antivirus, anti malware, etc. So when I got done putting everything I wanted on my SSD I have 60gb free space out of the 98gb usable space. Another thing I want to add is that I did a FRESH INSTALL of Windows 10 on the SSD using a USB recovery drive which was so simple to do that the entire process including Windows reinstalling itself took me maybe 30/40 minutes and the SSD was good to go with ABSOLUTELY NO PROBLEMS at all. Also, the SSD made all the recovery partitions just like my original HDD that came with my computer. Here's the steps I used to install my SSD with Windows 10 and it couldn't have gone any smoother: 1. Disconnect the POWER and SATA cables of any drives in your computer. 2. Install the SSD and let it boot up. After that reboot and go into your BIOS and change the "SATA" setting to AHCI. Then reboot. 3. Now you will either use recovery discs or a USB recovery drive to boot into the SSD and install your OS. 4. After the install of your OS is finished go back into your BIOS and change the boot order (if your are using more than one HDD/SDD) so that you make the SSD with your OS the first in line so your computer knows that's where you want to boot from. After that, your are done my friend and you can start enjoying your new speedy SSD.
