Why? I know several people with HDs that are running just fine.
That's OK then feel free to wait ~3-6 months for IBD Spinning disks do not read/write fast enough compared to SSD's
My internet connection on my server will be way lower than the read/write speed of any modern drive. Does it really take that long to download the blockchain?
With HDD I've known many folks (including myself) that the IBD never completed (blocks come in faster than the HDD can validate block headers) Internet speed doesn't matter* Its all about how your device reads/writes data *any basic ISP package will suffice
