Mounting a 2nd HD on my laptop: 12.7 - 9.5 or 9 mm caddy adapter?

[Maverick6]

Hi, I want to replace my dvd rom with a cool ssd I've just bought. Anyway I found that there are at least three kinds of "universal" caddy case adapter: which measure will fit to my HP 15-r209nl?

You do NOT want to put an SSD in an optical bay caddy. It will run slow and you will have wasted the money it cost. You can't boot from it, either.

Put the new SSD inside the laptop and use it for Windows to take advantage of its speed and put the older type mechanical spinner disk (your original 1 TB 5400 rpm slow disk) in the DVD caddy.

This is the Service Manual:

See p. 2. The optical drive is a 9.5 mm model.

Page 43 shows how to remove the optical drive.

Page 59 shows hard drive replacement.

Thank you for your reponse, I needed information for upgrading ram too and I couldn't find the manual. Anyway I still want to ask: if I put my older drive in optical bay caddy, shouldn't I be able to boot from it? Why?

The BIOS is not expecting to see a hard drive in that hardware address. In fact, a drive in the optical caddy will only be visible to an operating system as it will just see that port as a kind of SATA port and activate the hard drive but you will not see it in the BIOS.
