Score: 75/100Rankings
The Samsung T7 Shield is a rugged portable SSD delivering up to 1,050 MB/s read speeds and strong IP65 protection. Its added rubberized shell makes it heavier and slightly bulkier than the standard T7. Ideal for photographers and gamers who need durability in harsh environments.
The Seagate Storage Expansion Card for Xbox Series X|S adds up to 4 TB of native-speed storage via a PCIe Gen4 x4 NVMe interface. Its performance is slightly lower than the theoretical maximum and it works only with the Xbox Series X|S ecosystem. Best for gamers who need seamless expansion without cables.
