Pros: I've owned the Seagate FireCuda 520 2TB for about a month now. Absolutely amazing SSD. * Absolutely blazing fast * No massive heatsink to have to remove to fit it under the graphics card

Cons: * Nothing as of yet. Has run flawlessly.

Overall Review: Would definitely recommend this to other people. Seagate for the longest time hadn't really tried to compete in the SSD market, but with their FireCuda series, they have really hit a home run. Admittedly it is with the same E-16 Phison controller that everyone else is using, but I believe they did it right. If you want a good M2.2280 SSD on PCIe 4.0, I believe this is the one to buy right now. If you can wait for drives on the new E-18 Phison controller, it will bring significantly higher IOPS and sequential speeds.
