ThinkPad E550 - DVD SATA capabilities

[Sheldon88]

Hi everyone,

I own a ThinkPad E550 whose HDD interface is SATA III.
My question is: can I deduce that also the DVD-ROM Drive connection is SATA III (even if the drive itself is, of course, SATA-I)?

I'm asking this because I'd like to replace my DVD-ROM with a caddy, in order to install a SSD Drive.

Thank you!

Its not safe to assume that but you can always mount the HDD in the caddy and trhe ssd in the hdd slot. A laptop hdd won't be bottlenecked if the interface turns out to be sata1 which is good for ~150MB/s.
