Hi all,
As per post title I'm looking to upgrade my existing 1TB 2.5" Sata (eSata?) HDD to a larger capacity drive.
Are all 2.5" Sata/eSata HDD units suitable as direct "swap out - swap in" candidates or is there a specific "form factor" or mounting format that I need to be looking for?
Obviously any specific suggestions for compatible HDDs would be useful.
I'm "hoping" that there's reasonably priced options that are > 2TB and not interested in spin speeds lower than the current 1TB 7200 RPM unit that's currently installed.
Thanks,
Jim

Thickness was once a problem but the market has pretty well boiled down to either 7mm or 9.5 mm HDDs and SSDs either of which will work for you. You see some thicker ones but they are for servers. I have not purchased a mechanical hard drive for several years so I am not real clear on the price differentials. I had a bit of trouble finding a 2 TB 7200 rpm 2.5 inch drive. I think you would be fine with say a Seagate Barracuda 2.5 inch. 5400 rpm but a 128 meg cache so really performs well

Its specs
https://support.hp.com/au-en/document/c05373631
It has
1 TB 7200 rpm SATA
128 GB M.2 SSD
You have few options
1. Upgrade M.2 SSD from 128GB to 2TB only. It can be M.2 SATA or M.2 NVMe (faster, and more expensive) for example

2. Upgrade 1TB SATA to 2TB or 4TB 2.5" SATA SSD only
3. Upgrade both
Regards.

Thanks, but I already know what my "theoretical" upgrade options are - I'm asking specific "practical" questions regarding what specifications, mostly physical, replacement HDD Drives need to meet to be "swap" compatible with the current factory installed drive.

Current form factor is a 2.5 inch SATA HDD. All 2.5 inch SATA HDDs and SSDs have the same external physical dimensions so are swappable using the same mounting hardware. It's 2025; I would not get a mechanical hard drive, get a 2.5 inch SATA SSD. The performance improvement is very substantial if it is your system disk. However since you have a 128 gig M.2 SSD the OS is likely on it and replacing the 1 TB drive will not result in significant improvement except in transfer speeds from the 1 TB such as editing videos or photos. Still worth replacing HDD with SSD I believe.

Hi, thanks for the info. - I suspected that most 2.5" form factor drives might physically fit, but wasn't sure if there "thickness" might vary, and also whether the location (and/or) number of mounting screws could also be an issue.
I appreciate the benefits of an SSD upgrade vs HDD, but as I'm also looking to keep the cost down it's definitely a 7200RPM HDD that I'm looking for.
