G551J > I Want To Replace The Optical Drive with an SSD Drive Using a Caddy.

Hello awesome ROG community! 🙂
First, please forgive my bad English!

I have a ROG G551J laptop and I want to replace the CD drive with an SSD storage using a caddy. Is it possible on the G551J?

I want to know what caddy size should I order. And I'm planning to put the windows system on this new storage, I use this laptop with my office work, so I carry my laptop everyday, will the new storage placement get affected with the vibrations of being carried in the bag everyday?

EDIT: And please, is the optical drive connector for this model is SATA II or a SATA III?

Thanks in advance!

Thanks guys for the replies!

My model already has 128 SSD and 1 TB HDD but I feel the SSD size is so small to carry the OS and other apps including my desktop, it's already full and I don't want to delete anything anymore xD.Sso that's why I want to insert a new SSD and move the OS to this new SSD.

How did you know this? He should just test the ssd in his laptop to know for sure. I have an old G752VT and I have tested an SSD in a caddy at the optical bay and it turned up as sata 3. If you connect an optical drive, it will show as sata 1 but if you connect a sata 3 device, it will also show a sata 3 device. I have verified this a long time ago using crystaldiskmark fyi.


Well that's really interesting because I did run HWinfo and it did say the optical drive is a SATA 1.5
So maybe I should give it a try too.

basically the Speeds will be half of those here the main drives are


So you mean even if it turns around to be a SATA III in the optical drive side it would not be as fast as the main SATA III drive in the HDD side?

A standar 2.5 drive is good enogh


Appreciated man! thank you!

Yeah because main drive uses 6Gbps and caddy only 3gbps. SO if you have speeds greater than 250mb/s it will be useless so putting ssd in there is stupid but putting hdd is fine.
