Work out how long it takes, how much it holds, and what it costs
Pick a calculator, drop in your numbers, and get a figure you can plan around — RAID capacity, IOPS, transfer time, storage cost, SSD endurance and more. Every tool understands both decimal and binary units, so a GiB and a GB never get mixed up along the way.
No tool matches that yet.

Why Use These Calculators
Storage and networking math is full of easy-to-miss gotchas: decimal vs binary units, parity overhead in RAID, protocol overhead on network links, wear leveling on SSDs. These tools encode the actual formulas — usable capacity after parity, rebuild time under URE risk, real DWPD from a write workload — so you get an accurate number instead of a rough guess.
