Japanese ISPs are now offering super-fast 10Gbps internet connections, with NTT East and NTT West (Nippon Telegraph And Telephone) providing people with 10Gbps internet for just $55 per month.
10Gbps is pretty damn insane as it'll offer users over 1GB/sec download speeds, but you probably won't get those speeds for a variety of reasons. You'll need a SSD that can drive over 1GB/sec read/writes, with SATA III maxing out at 600MB/sec you're going to need an NVMe-based SSD capable of multiple gigabytes per second of speeds... for your internet connection.
The super-fast FLET's Hikari Cross compatible router is there for your 10Gbps internet service needs, costing around $4.48 per month on top of your $55 internet connection. You will have 10Gbps support as well as Wi-Fi 6 support, so you're looked after in both wired, and wireless connectivity at high speeds.
