Can the P360 Ultra's RAID setup be configured for both performance and redundancy


Yes, the Lenovo ThinkStation P360 Ultra supports RAID configurations that can provide a balance of performance and redundancy:

RAID 0 for Performance

- The P360 Ultra supports RAID 0 striping across multiple M.2 NVMe SSDs
- This allows splitting data across drives for significantly faster read/write speeds
- However, RAID 0 offers no redundancy, so data loss occurs if any drive fails

RAID 1 for Redundancy

- The P360 Ultra also supports RAID 1 mirroring of M.2 NVMe SSDs
- This creates an exact copy of data on two drives
- If one drive fails, the other can still provide access to the data
- RAID 1 sacrifices some performance compared to RAID 0

RAID 5 for Balanced Performance and Redundancy

- RAID 5 is supported on the P360 Ultra with at least three drives
- It stripes data across drives with distributed parity for redundancy
- This provides good read/write speeds and can tolerate a single drive failure
- RAID 5 offers a middle ground between the performance of RAID 0 and redundancy of RAID 1

So in summary, the P360 Ultra's RAID capabilities allow optimizing for either performance (RAID 0), redundancy (RAID 1), or a combination of both (RAID 5) to best match the needs of the workload. The specific RAID level chosen will depend on the relative importance of speed vs data protection.
