 His xbox one is out of storage and he wanted to install more games

My son asked me for more storage for his xbox one. His xbox one is out of storage and he wanted to install more games. We search around and this hdd is the most affordable for the most storage. I mentioned that it is compatible with xbox one, easy to install , just plug and play. We received it, plug it and and he got his extra storage. He installed few games 2K and Madden and he run the game directly from hdd, all worked flawlessly. I recommend this product.

 I have tons of digital files and my computer was running low on storage so I started looking for an external hard drive

I love the small size of this external hard drive and its 2TB capacity. I have tons of digital files and my computer was running low on storage so I started looking for an external hard drive. This one fit all my needs and was competitively priced. So far it is working great and my computer is running much better without being clogged down by the files.

 Definitely not rugged though

It is much smaller than I thought it would be, and seems put together well enough. Definitely not rugged though. It connected to my Xbox and was instantly recognized and ready for formatting which went super smooth. The speeds are very close to what they are advertised as. I got an average of about 710-750 Mbps which is close to the converted advertised speeds of 800 Mbps. It does get a slight dip in speeds around the first 10 seconds and last 15 seconds of a transfer, but it only fell to 650 Mbps which is still fast enough for me. Very good value for money. Also does stay relatively cool during sustained transfers however it did eventually begin to get a little bit warm, but not concerningly warm or anything. My drive did only come with 698 GB when it should have come with 750 GB, but overall seems like a great product.

Works well performs well

 I can put photos and videos and files on it, I did have to look up how to use it, but it’s reliable

Love the storage it gives me. I can put photos and videos and files on it, I did have to look up how to use it, but it’s reliable. all my files are in the storage once I put them in there, it’s great. The speed to load everything may depend on how much you’ve put in there, I’ve put around 1,000+ photos and it takes a little to load but they’re all there. The weight isn’t heavy and it’s easy to carry around if need be. Good value for money and in the az heat it’s resistant to any higher temps in the car if left. But I wouldn’t recommend leaving anything electronic in the heat for a long time lol. Comes with its own cord and easy to plug in.

 It’s got enough storage space that I only need the one for all my classes, and it’s small and easy to cart around with my other school supplies

I use this for my audio/video production classes — we’re in the second semester, and this little guy is still going strong. It’s got enough storage space that I only need the one for all my classes, and it’s small and easy to cart around with my other school supplies. It’s compatible with both computers I use (one school PC and my school Dell laptop), and is incredibly reliable. The processing speed is more than enough, and as long as you keep folders it’s easy to keep things organized and readable on it.

 This was the perfect drive for my purpose at the right price, I installed it in literally 2 minutes, and it's fast

I needed a small-footprint dedicated external drive for backing up my 256Gig SSD internal drive on my M1 MacBook Pro, so I didn't need anything larger than a 750Gig drive. This was the perfect drive for my purpose at the right price, I installed it in literally 2 minutes, and it's fast. A good deal all around.
