16 TB. 4 BAY NetGear Advanced Network Storage

NETGEAR ReadyNAS 424 NAS server 16TB - Network Attached Storage - RN424 RND-4G To accurately describe the space in the NETGEAR ReadyNAS 424 (RN424) when it has four hard drives, we need to know the size of each drive and the RAID level being used, as this determines the usable space. Since the used unit you asked about previously was listed as 16 TB total, it is most likely populated with four 4 TB hard drives (4 x 4 TB = 16 TB raw capacity). Here is the usable space for the 4 x 4 TB configuration under the most common RAID options for a 4-bay NAS: Usable Space with 4 x 4 TB Drives (16 TB Raw) | RAID Level | Drives Used for Redundancy | Usable Capacity | Data Protection (Fault Tolerance) | |---|---|---|---| | X-RAID2 (Netgear's Default) | 1 drive (Variable) | ~12 TB | Can lose 1 drive without data loss. | | RAID 5 | 1 drive | ~12 TB | Can lose 1 drive without data loss. | | RAID 6 | 2 drives | ~8 TB | Can lose 2 drives without data loss. | | RAID 10 (1+0) | 2 drives | ~8 TB | Excellent performance; can lose 1 drive per mirrored set. | | RAID 0 (No Redundancy) | 0 drives | ~16 TB | Fastest speed, but if ANY drive fails, ALL data is lost. | The NAS is almost certainly configured using RAID 5 or X-RAID2, which provides the best balance of capacity and data protection, resulting in 12 TB of usable space. Summary of Space * Raw Capacity (Total physical space): 16 TB * Likely Usable Capacity (Protected): ~12 TB (with one-drive redundancy) * Absolute Maximum Usable Capacity (Unprotected): 16 TB (only if configured as RAID 0)
