Measure first.
Then decide.
Free utilities to analyze your devices and calculators to size the right maxRAID array.

RAID‑10 to maxRAID
See how many fewer SSDs you need to replace an existing RAID‑10 array — with the same performance.
Open calculatorAdjust SSD count and size, target usable capacity, array writes per day, free space and block compressibility.
maxRAID Tools
Know your data.
Command‑line utilities that analyze storage devices — so you can see exactly what maxRAID will do for your workload before you deploy it.
Device scan Non‑destructive
Analyze a block device to measure its compressibility and fill level — insight into efficiency, performance potential and wear.
Benchmark Destructive
Write‑intensive performance tests for unmounted or unused volumes. Tune block size, read/write ratio and compression level.
