Should I consider upgrading to dual pathing on the SA120?
---
- Single SAS Cable (1 lane) Connection: Approximately 1200MB/s
- Dual SAS Cable Connection (2 lanes i.e., dual pathing): Approximately 2400MB/s
Edit: According to GPT 4:
So the real answer Is that i need a layer of flash storage on my network and then the spinning disks become more archival vs our practice today where we just dump every thing across a few storage pools on the DAS

Edit: According to GPT 4:
--Your Lenovo SA120 has WD 14TB and HGST 4TB drives, both with SATA III 6Gb/s, capped at around 600MB/s. Current single SAS cable provides 1200MB/s, so the drives limit the speed, not the connection. Upgrading to dual pathing (~2400MB/s) won't increase performance significantly due to these drive speed limits. However, it'll improve redundancy. The true benefits of dual pathing are seen in a multi-user environment or with faster SSDs, but it's less impactful for your HDDs.
