I have the 480 gb in my HP 2-in-1, and the 960gb in my old gaming laptop.
For the price-per-gb on an SSD, this is a really good deal, even without the sale price. Performance wise, there are better options out there.
Installation in my 2-in-1 and in my gaming laptop was pretty straightforward. The hard part was opening up the netbook since it had to be completely taken apart and had no access panel, but youtube was very helpful with that. Once I had it open, it's pretty much just plug-n-play.
Ideally you'll want to just do a fresh OS install, and mount your old drive in an external enclosure to copy your old files over and use for extra storage. Pick up a USB thumb drive if you don't have a DVD drive. All versions of windows can be downloaded for free from Microsoft. You'll need an activation code to validate though. Just type in all zeroes if you don't have an activation code.
Windows 10 doesn't have the annoying windows activation popups found in previous versions, you just can't right click the desktop to change the background image unless you have a valid activation key. You'll have to right click an image and set it as your wallpaper from there.
Most pre-built systems have an activation key sticker on them somewhere. If you can't find a sticker, and you're a smart person with access to google, you can probably find a way to recover your current activation key.
If you prefer to have all of your old programs and settings, just on the newer drive, and not have to go through the whole setup process, you'll still need an external drive enclosure to clone your old drive to the new one, unless you have room for two hard drives.
In the instructions with this drive you'll find a free product key for a hard drive utility. Follow the instructions there to do a complete clone of your hard drive.
You'll need to make sure the entire drive image is cloned over, not just copied, otherwise you'll have problems booting into windows, and you'll need to load up a windows installation disk to load up into boot recovery mode. If you're having trouble with the included software, there's plenty of other free options available that will do the trick like "clonezilla".
Either way, before you pull your old drive out, make sure you have the following.
1: New Hard drive
2: Windows installation drive, for installing windows, or recovering boot manager, either on DVD or USB thumb drive.
3: External hard drive connector or enclosure so you can clone your old hard drive, or copy over important files, and to use the old drive as external storage/backup
4: Your windows activation key.
If you're going from an old-style hard DISK, you will notice a MASSIVE improvement in load times of windows and all of your programs. It will make your computing experience overall snappier. This is a great upgrade to breath new life into an aging computer as long as you don't have too many other limiting factors. If you're just looking to upgrade from a smaller SSD, the performance of this drive can be a little underwhelming.
The drive is lighter in weight than a traditional hard disk, has no moving parts, so you don't have to worry about your disk headers crashing from bumps and bangs.
There's a 3 year warranty, the manufacture doesn't specify any limitations on this drive as far as maximum program/erase cycles. Generally SSDs have a limited number of read/writes they can perform before they start to give up and become unreliable. As long as you're not writing 100gb/day to this drive, you shouldn't have to worry about it not lasting the 3 years.
Everyday users who don't do a whole lot of file transfers could expect to get 5-7 years out of their drives. If you have important files though, it's always a good idea to do regular backups.
It's definitely worth picking up one of these drives, especially when they go on sale. Pricing at BestBuy with this particular product is often competitive with online retailers, sometimes cheaper, especially when you factor in the cost of shipping.
