How about these? Connecting 4TB 3.5 SSHD to Laptop through Internal Port?

[sammy]

Hi Guys,

(This may sound stupid but still....)

I have Dell 6th Gen i7 with 16GB RAM, What if I remove 2TB hard disk and connect 4 TB SSHD to it through SATA and POWER cord extension , will my 4TB SSHD work faster than what it used to be with USB 3.0 Hard Drive Dock?

Ofcourse I will have to remove my laptop back panel to do it...



Thanks..

It won't work.
3.5" drives use 12V line for motor power, while 2.5" drives mostly rely on a 5V line and don't even use 12V.
You can either use a regular SATA cable and deliver power to your HDD externally (did that on my ARM miniPC once), or forget the idea and stick to external enclosure.
If you connect it directly, you may get nothing at all, or the worst case - burn few mosfets on a 5V rail on your laptop.

From the performance perspective - there will be no significant gain. The only thing that may improve is drive latency, but that is only my theoretical assumption.
