У меня есть SATA 3, но получить только 3 Гбит / с?

Вот выходные данные dmesg | grep SATA:

[    1.244456] ahci 0000:00:1f.2: AHCI 0001.0300 32 slots 6 ports 6 Gbps 0x11 impl SATA mode
[    1.256512] ata1: SATA max UDMA/133 abar m2048@0xc0817000 port 0xc0817100 irq 42
[    1.256525] ata5: SATA max UDMA/133 abar m2048@0xc0817000 port 0xc0817300 irq 42

[    1.904299] ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

Из первой строки я понимаю, что у меня есть порты SATA III 6 Гбит / с * 6. Пожалуйста, поправьте меня, если я здесь не прав. Предполагая, что я прав, я не понимаю, почему мой второй жесткий диск, который подключен к моему оптическому отсеку с помощью iConnect caddy , имеет скорость 3 Гбит / с. Я на 100% уверен, что жесткий диск SATA 3. Есть ли способ, которым я могу восстановить его скорость? Ну, это может быть кедди, но как мне в этом убедиться? На странице продукта нет информации. .
