What matters most to you?
This helps us recommend the best RAID level for your needs.
How many drives do you have?
Enter the total number of identical drives for your array.
Recommended: 4+ drives for best redundancy options
💡 Tip
With 4 drives, you can use RAID 5 (lose 1 drive to redundancy) or RAID 10 (lose 2 drives but get better performance).
What size are your drives?
Enter the capacity of each drive (all drives should be the same size).
Common sizes: 2TB, 4TB, 8TB, 12TB, 16TB, 20TB
📦 Total Raw Capacity
4 drives × 4 TB = 16 TB total raw storage
