Which one should i get and whats the benafits
Absolutely the SSD, be it 2.5", m.2 (SATA or NVMe), or PCI-e.
Optane is simply a (small..16 or 32GB) cache for an HDD. An SSD is fast across the whole drive.
Optane is a niche product right now...basically in the same place SSD's were several years ago. Too small and expensive to be useful by itself, so just a cache for a spinning drive.
But...it is the new fancy buzzword.
