This is highly dependent on what your needs are and how you plan to solve it. SATA-3 maxes at 6gbit, which SAS-2 had in 2009. Most cards are x8, and have at least 4 full speed SAS lanes (of whatever generation). That means 24 Gbit. PCIe x8 2.0 (from 2007) had 4 GB (32 Gbit). So if that meets your needs, you can run it on an ancient board.
However, if you need something more advanced, such as SAS-3, a SAS expander, or a card with more native lanes, then you would need to plan accordingly.
I’ve been running on an LSI 9211-4i4e, which is only a PCIe 2.0 card, for many years. I did notice my speeds dropped when I expanded the 4e to a 15-bay DAS (plus the 4 internal SATA drives), but it’s still enough to meet my needs.





Now is probably a good time to remember what a VPN can and cannot do. It can block your ISP from knowing which sites you’re going to. It can bypass ISP-level blocks, including geo-blocks.
It cannot stop the endpoints (WhatsApp, both the client and server) from harvesting whatever data they want from there.
Meta is clearly concerned about bans on WhatsApp. This is nothing more than their own self-interests.
