er, it takes forever to start upthere seems to be a lot of Dell bloatware that it could do without.So here is the process for installing this on a laptop:1. Obtain a USB to SATA adapter cable.I did not realize I needed this to hook up the SSD for cloning until after step 2 so I had to wait a few days after I ordered it.2. Clean up and back up your hard drive.The SanDisk SSD 480 GB is smaller than the hard drive on my Dell (750 GB), and I had a lot of photos, videos, and music taking up a lot of room. So first I cleaned up my hard drive and got rid of junk I did not want anymore. Then I backed up my personal files, including all of those aforementioned photos and videos, before deleting them from my hard drive.3. Clone your existing hard drive.After I received the cable, I downloaded Macrium Reflect cloning software from download.com. I considered buying the software recommended by Sandisk, but other reviewers recommended Macrium Reflect. It also got good reviews from CNET. Macrium was easy to use, but it took a while to clone my hard drive onto the SSD. Plug the SSD into your USB port using the adapter. My computer at first did not install the driver for the SSD until I unplugged another USB device that was pulling power from my computer. Of course, keep your laptop power supply connected during this processdon’t try to do it on battery power. After opening the Reflect program, I decided to watch one of their Help videos on cloning a drive, which was very helpful. I followed those directions and proceeded to clone the drive. It took about two hours to complete the clone (about 125 GB of data).4. Install the SSD.Then all you have to do is install the SSD, which is also very easy if all the screws cooperate. Turn off and unplug your laptop. Turn it over. Remove the battery. Unscrew and remove the back panel covering the hard drive (on the Dell, I just took a guess and removed the central panel and there was the hard drive, the same size as the SSD). Remove the screws holding the hard drive bracket in the laptop, gently pull the hard drive out of the connector using the plastic pull tab on the bracket, and remove the hard drive. Then remove the screws holding the hard drive to the bracket (one of mine was difficult to remove and almost got completely stripped before coming loose. Attach the SSD to the bracket in the same way using the same screws. Set the SSD in the laptop where the hard drive was and slide the connector in place. Then screw the bracket in place using the same screws. Reattach the back panel, reinstall the battery, plug the computer back up, and start it up. The computer then required a restart to finish the installation, and that was it. The whole install process took less than 20 minutes (after the cloning part).The difference in performance was immediately noticeable. Where before it took five minutes to start up, it now starts in less than 30 seconds. All tasks, from loading web pages to starting programs, are quite zippier than before.I wish I had the bigger size (960 GB), but this should encourage me to keep my mess of photos and videos in better order. My only complaint is that I did not initially realize that I needed the USB to Sata adapter until I sat down to install this and then had to wait a few days while I ordered it. But that is really my own fault for not doing the research beforehand. Anyway, this is a great upgrade to my computer. Highly recommended.

he Samsung 850 Pro. The Samsung, however, uses its own controller, which you can argue is better because they have direct control over the components that go into the SSD, but you probably won't be able to really tell the difference during normal usage. At the time of this review, the Sandisk is $189 vs $217 for the Samsung.If you're looking for a primary SSD for your OS, this wouldn't be a bad choice. The Samsung 850 and 950 are also good, but they tend to be a bit more expensive with similar specs. Intel SSDs are also top of the line, and the price reflects that.
