Final answer:
To achieve storage redundancy with maximum performance and using minimum drives, select SSDs (Solid State Drives).
Step-by-step explanation:
If you want to build a PC for storage redundancy with maximum performance and using the minimum amount of drives, you should select SSD (Solid State Drive).
SSDs are faster and more reliable than traditional HDDs, which makes them ideal for storage redundancy and maximum performance. Although SSDs are generally more expensive per gigabyte, you can use fewer drives to achieve the same or even greater storage capacity compared to HDDs.
For example, you can set up a RAID (Redundant Array of Independent Disks) configuration with multiple SSDs to achieve both redundancy and high performance. This way, if one drive fails, your data will still be safe and accessible.
