  • Good price, quick delivery
Capacity: 1TB Style: SSD
Not much to say, very recommended Hardware, quick to set up if you have the tools, JUST KNOW IT’S NOT COMING WITH THE NECESSARY SCREWS TO CONNECT IT SO MAKE SURE YOU HAVE THOSE.

  • Works as intended.
Capacity: 2TB Style: SSD w/ Heatsink
Installed no issues. Speed is strong, although I have a 3.0 compatible motherboard the backwards compatibility allows it to still function. Will update review whenever I have issues with the drive. So far so good. Note: It did only have 1.81 gb free but I never found a drive that gives you the full amount of storage on it's title; so I don't really care. ... show more

  • no moving parts!!
Capacity: 4TB Style: SSD
My son built me a high end desktop computer for father's day years ago. We keep upgrading it and adding on as the technology and memory demands change. My regular hard drive with moving parts was one of the last things to change. It was still working but it was bound to fail sooner or later. We got this and installed. I've had it for about 3 months now and no issues at all. I hope it will last for years to come. I run Windows on a solid state 500 GB and everything goes on this. It has plenty of room on it and it won't break your budget. ... show more

  • Does what I wanted it to.
Capacity: 1TB Style: SSD w/ Heatsink
Got my TB of storage delivered quickly, installation was quick and easy per YouTube. Would 100% recommend if you’re a ps5 user wanting to get more storage out of your console, all while utilizing a powerful SSD. Considering normal use and wear and tear, I have experienced no issues with using it and it’s been months. ... show more

  • Classic Western Digital quality
Capacity: 1TB Style: SSD
I've had good luck with Western Digital hard drives, so I opted to get one of their NVMe M.2 SSDs for a new PC as its boot drive since the price was great. The speed is great, the price for the capacity is great, and I don't have many worries about reliability. I've had some bad luck with flash media, which scared me away from SSDs for reliability and lifespan concerns, but I think this will help dispel that fear. ... show more

  • Quick and slick
Capacity: 2TB Style: SSD w/ Heatsink
It’s pretty annoying that a memory stick doesn’t come with a spare screw to help secure it into the socket so it won’t flop around but I guess that’s caveat emptor. Either way it works just fine and is speedy even on older gen3 motherboards that do not support gen4. Super easy to install literally just plug it in and then run disk management to assign it a drive path and you’re done. ... show more
