Am I limited to the number of hard drives I can install in my desktop internally ?

[KevinJH]

Dear Sir / Madam

Product No. Z7D30EA#ABU

System board: 82F2 00
BIOS: F.46

Further to my earlier question about HD replacement; https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Replacement-HD-advice/m-p/79116...

On checking inside the cabinet, there appears to be only one data connection point on the motherboard - would I be correct in thinking this ?  I was hoping to install a 1TB SSD with OS and selected programmes on along with a 2TB HDD for other use/storage. I have a feeling that this won't be possible but would really appreciate your advice/confirmation.

If, as I suspect, I'm only able to have one internally connected drive I guess I could run a second drive externally.

Thanks again in advance for any advice you can give.

NO HP product ID# told :  Pavilion Desktop PC 570-pO54na  ( change  O to 0 use  zero here)

there is no limits,  just these.

1. lack of SATA data ports,  just  look see them. or missing generic sata dta cable>
2. lack of SATA power ports and the sata power  cables missing, did you look for them? first , BOM shows no spec.cable.
3. no OS limit  you  will hit , GPT formatted w10 64 bit does that automatically. no 2TB limits.

my guess you are bingo on 2

keep in mind I can not see inside your PC nor over your shoulder.  for sata ports and 15 pin sata power cords missing

Thanks for your reply, Savvy2.

HP product ID added in OP.

I appreciate you're unable to see over my shoulder but here's an HP link to the MB for this unit:

With only the two sata sockets (in use) I guess I'm unable to add a second HD after all.
