Most of Storage Server use the following disk for performance

• IDE Disk
• SATA Disk
• PATA Disk

If we want to configure RAID

• Disk should be dynamic disk
• Disk can be basic disk
• Disk should be SSD
• Disk should be HDD

The best practice for ensuring high I/O performance is

• Making the logical volumes the same size as the physical disk.
• Dedicating the physical disks to logical volumes.
• Spreading the logical volumes across all logical disks using striping
• Spreading the logical volumes across all logical disks using concatenation
