最近想買USB3.0擴充卡來用 Renesas 720202
但發現大部份的擴充卡的需求都是寫PCI-E gen2.0 (5Gbps)
而我的主機板是華碩 P5B ,去查的結果都沒有寫是什麼版本
以年份來猜測,九成應該只有PCI-E gen1.0 (2.5Gbps)
假設直接除以10來算
PCI-E 2.0的理論值是500 MB/s
PCI-E 1.0的理論值是250 MB/s
我只打算拿來接隨身碟或外接硬碟而已(非SSD)
讀寫速度只要有100 MB/s就很夠了
(當然…隨身碟在原生usb3.0可以可以跑超過100 MB/s)
請問買USB3.0擴充卡插在PCI-E gen1.0 速度跑得到嗎?
