Firstly, I’m honored to be the first person to write a review of this product for Best Buy (BB). I’m not endorsed by BB. I will also say, I managed to get this product on sale and use my BB vouchers which was $70 in total. So with the sale price of $199.99 minus $70 with tax it equated to about $138. Which i think is a steal. Considering the 1TB is around $129-139 retail. With this being said. This has got to be your priority addition for any Xbox X/S owner. I feel the speed of the C50 is fast. Transfer speeds between internal and C50 were around 6-7 GB/s for me. I assume there is deviations for each card. Load times of games, i also feel are faster than the interal storage. CoD loaded within 1-2 seconds from the home screen to intro movie. This is a beefy game at 300+ GB for me. I HIGHLY recommend getting this addition, i would say wait until its on a decent sale ($20-40+) to get it. The C50 also out performs the Seagate competitor, but it is negligible. To install, just slide it into the slot at the rear of the console. Boot your console up and thats it! Your xbox automatically identifies the C50 and is ready to function with Xbox Velocity architecture. To transfer files simply select the drive youre wanting to move FROM and select Move/ Copy Items. Then select what you want to move, select move and then choose the C50. Itll take a second but once its intiated itll launch the update screen and queue the transfers as if you were updating games, except instead of downloading you’re transferring. A nice feature is the included travel case for it.

Surprisingly easy to install. Was ready in seconds. Downloads may vary, but it’s the same speed as the internal drive.
