## Tools

- [RAID Calculator](https://www.prodisknetwork.com/tools/raid-calculator): usable capacity (decimal TB and binary TiB) and drives needed for RAID 0, 1, 5, 6, 10, 50 and 60, before filesystem overhead; lists in-stock drives of the chosen size with live prices. Example: 200TB usable from 24TB drives in RAID 6 takes 11 drives (216TB, 196.45 TiB).
- Per-level calculators with formula, minimum drives, fault tolerance and capacity tables: [RAID 0](https://www.prodisknetwork.com/tools/raid-calculator/raid-0) · [RAID 1](https://www.prodisknetwork.com/tools/raid-calculator/raid-1) · [RAID 5](https://www.prodisknetwork.com/tools/raid-calculator/raid-5) · [RAID 6](https://www.prodisknetwork.com/tools/raid-calculator/raid-6) · [RAID 10](https://www.prodisknetwork.com/tools/raid-calculator/raid-10) · [RAID 50](https://www.prodisknetwork.com/tools/raid-calculator/raid-50) · [RAID 60](https://www.prodisknetwork.com/tools/raid-calculator/raid-60)
- RAID planning guides, each with the calculator on the page: [How many drives can fail in each RAID level](https://www.prodisknetwork.com/tools/raid-calculator/how-many-drives-can-fail) (RAID 5 survives 1, RAID 6 any 2, RAID 10 at least 1 and up to one per mirrored pair; RAID 50/60 per group) · [RAID hot spare](https://www.prodisknetwork.com/tools/raid-calculator/raid-hot-spare) (what a hot spare does and how it changes the drives you buy (no added capacity)) · [TB vs TiB](https://www.prodisknetwork.com/tools/raid-calculator/tb-vs-tib) (why a 24TB drive shows 21.83 TiB; conversion table for drive and array sizes) · [RAID write penalty](https://www.prodisknetwork.com/tools/raid-calculator/raid-write-penalty) (1 disk I/O per random write in RAID 0, 2 in RAID 1/10, 4 in RAID 5/50, 6 in RAID 6/60, with the IOPS formula) · [Best RAID level for 2 to 8 drives](https://www.prodisknetwork.com/tools/raid-calculator/best-raid-level-by-drive-count) (which levels work, usable space and failures survived per drive count) · [RAID 50 vs RAID 60](https://www.prodisknetwork.com/tools/raid-calculator/raid-50-vs-raid-60) (usable capacity and fault tolerance compared for 12, 16 and 24 drives) · [RAID 6 vs RAID 60](https://www.prodisknetwork.com/tools/raid-calculator/raid-6-vs-raid-60) (when to split a wide array into groups)
- [CCTV Storage, PoE & UPS Calculator](https://www.prodisknetwork.com/tools/cctv-storage-calculator): security-camera storage from per-camera bitrate, recording hours and retention days (decimal TB and binary TiB), NVR drives as independent disks or RAID 1/5/6/10 with bay and drive-size limits, PoE switch budget by IEEE class or measured draw, and UPS load (watts) with a runtime upper bound only from battery Wh. Example: 8 cameras at 4 Mbps for 30 days = 10.37 TB of footage.
- [UPS Battery Backup Calculator](https://www.prodisknetwork.com/tools/ups-calculator): equipment watts to a minimum UPS watt rating with headroom (default 80% loading), power factor from W/VA, and runtime only as an upper bound from battery Wh (battery Wh x inverter efficiency / load); real runtime comes from the manufacturer runtime chart. Example: 620 W load needs a UPS rated at least 775 W.
- [HPE Server Memory Configurator](https://www.prodisknetwork.com/tools/server-memory-configurator): checks a DIMM plan for HPE ProLiant DL360/DL380 Gen10 and Gen11 against HPE memory population rules (supported DIMM counts per processor, slot order, allowed mixes, per-processor memory limit) and gives the memory speed by processor and DIMMs per channel. Example: DL380 Gen11 with 2 x Gold 6448Y and 16 x 64 GB DDR5-4800 per processor = 2 TB at 4400 MT/s; Gen11 supports only 1, 2, 4, 6, 8, 12 or 16 DIMMs per processor.
- [WiFi Planner: mesh nodes and access points](https://www.prodisknetwork.com/tools/wifi-planner): mesh node count from the distance router-to-farthest-room at eero/TP-Link spacing (20-30 ft apart, max 50 ft on wireless backhaul; dense walls 20 ft), and business access point count as the larger of coverage (APs 30-50 ft apart, about 780-2,170 sq ft each) and capacity (people x 2.5 devices x 50% connected / 30-40 clients per AP, HPE Aruba). Includes WiFi 6 vs 6E vs 7 facts (320 MHz in 6 GHz, 4K QAM, multi-link operation). Example: farthest room 55 ft = 2-3 nodes; 10,000 sq ft office with 50 people = 5-13 APs.
- [WiFi 7 Mesh: How Many Nodes You Need and How Far Apart](https://www.prodisknetwork.com/blog/wifi-7-mesh-how-many-nodes-guide): one node per 20-30 ft from the router to the farthest room, at most 50 ft apart on wireless backhaul; a 55 ft run needs 2-3 nodes. WiFi 7 adds 320 MHz channels in 6 GHz, 4K QAM and multi-link operation but no extra range.
- [Mesh WiFi vs Access Points](https://www.prodisknetwork.com/blog/mesh-wifi-vs-access-points): mesh suits homes and small offices without cable; PoE access points suit spaces with Ethernet and many users. Comparison table and sizing rules from eero, TP-Link and HPE Aruba.
