What developers get via API

Every nas devices product includes access to structured knowledge. Here's a preview of what's available.

Error Codes

8 entries via API
Degraded RAID Array

One drive in the RAID array has failed or been removed. Data is still accessible but not protected. Replace the failed drive immediately — a second drive failure in RAID 5 means total data loss. Rebuild times: 4-24 hours depending on array size.

Severity: CriticalDIY Fix: Yes
Disk S.M.A.R.T. Warning

Drive self-monitoring has detected pre-failure conditions (reallocated sectors, pending sectors, or CRC errors). Back up data from this drive immediately and schedule replacement. Average time from first SMART warning to failure: 30-90 days.

Severity: HighDIY Fix: Yes
Volume Crashed / File System Error

File system corruption detected on a volume. Run file system check (fsck/e2fsck) from the NAS admin console. Do not power off during the check. Common after unclean shutdowns — always use a UPS with NAS devices.

Severity: CriticalDIY Fix: Possible

Maintenance Schedules

5 entries via API
Check disk health (SMART data)

Review SMART data for all drives via the NAS admin panel. Watch for: reallocated sector count, current pending sector count, and uncorrectable error count. Any non-zero values on these critical attributes warrant drive replacement.

Every month5 minEasy
Update NAS firmware/DSM

Check for and apply NAS operating system updates. These include critical security patches and stability fixes. Schedule updates during low-usage windows. Back up NAS configuration before major version upgrades.

Every month10 minEasy
Verify backup integrity

Test-restore a sample of backed-up files to confirm backup jobs are completing successfully and data is recoverable. Check backup logs for silent failures. Untested backups are not backups.

Buying Guide

1 entry via API
Bay count, RAM, and RAID levels

2-bay: minimum for RAID 1 (mirroring), home/small office backup, 50% usable capacity. 4-bay: RAID 5 or SHR (75% usable), sweet spot for home/prosumer use. 6-8+ bay: RAID 6 or dual parity for business, can survive 2 simultaneous drive failures. RAM: 2GB minimum, 4GB+ for Docker/VMs/surveillance. ECC RAM preferred for data integrity.

RAID level explainer

RAID 1: mirror (2 drives, 50% capacity, simple). RAID 5: striped with parity (3+ drives, n-1 capacity, 1 drive failure tolerance). RAID 6: double parity (4+ drives, n-2 capacity, 2 drive failure tolerance). SHR (Synology): flexible RAID allowing mixed drive sizes. RAID is not backup — always maintain an off-site copy.

Tips & Best Practices

5 entries via API
UPS and drive type recommendations

Always connect a NAS to a UPS with USB monitoring — unclean shutdowns cause file system corruption and data loss. Never use SMR (shingled) drives in a RAID array — they cause rebuild failures and degraded performance. Use CMR/PMR drives rated for NAS (WD Red Plus, Seagate IronWolf, Toshiba N300).

Data quality

How we build nas devices data

Cross-retailer matching

Every nas device is matched across retailers using UPC barcodes and model numbers. One product, all offers and prices in one record.

Cleaned product names

Retailer-specific noise stripped. Model suffixes, promo text, and inconsistent formatting normalized into a clean, consistent name.

Merged specifications

Specs pulled from every retailer source and merged. One store has dimensions, another has energy ratings — you get the complete picture.

Variant grouping

125 product groups — the same model in different finishes, sizes, or configurations linked together with shared base attributes.

Brands covered

85 brands with products in this category. 4 brands have customized knowledge data (brand-specific error codes, failure modes, and maintenance tips).

What you can build with nas devices intelligence

Backup monitoring dashboard

Use SMART data and error_code knowledge to build a dashboard that monitors drive health, backup job status, and RAID array integrity — alerting before data loss occurs.

Storage capacity planner

Use specification data (bay count, supported drive sizes, RAID level usable percentages) to calculate actual usable storage and plan for future expansion based on data growth trends.

Media server setup guide

Match NAS specs (transcoding capability, RAM, network speed) to media server requirements — recommending models that support Plex/Jellyfin hardware transcoding, 4K streaming, and remote access.
