Fire ratings are a time and a temperature, and paper and drives differ
A fire rating is two numbers and both are stated by the manufacturer: how long the safe was held in a furnace, and what internal temperature it did not exceed. The second is where document safes and media safes part company — paper chars around 175 °C (347 °F), while a hard drive or a memory card is damaged far lower, so a safe rated for documents is not rated for a backup drive. Here only the Amazon Basics FP1401M publishes its class (UL 72 Class 350, for paper), only the Master Lock L1200 states verification for CDs, DVDs and USB drives, and the two JUNDUN pouches state no duration at all. Five of the six also claim water resistance, which matters because a fire is followed by hoses. We compare stated duration and class, media protection, water resistance, anchoring and lock type.

The stated duration and internal temperature decide what the safe protects. The Amazon Basics FP1401M is the only one to publish its class — UL 72 Class 350, the interior below 350 °F for 30 minutes at 1,549 °F; HMF and Master Lock state 30 minutes at 1,549 °F without a class, BURG-WÄCHTER UL 72 and 30 minutes, and the JUNDUN pouches no duration.
A light fireproof box leaves with what it protects. The BURG-WÄCHTER FP 22 K is the only one in this hub whose listing provides for floor fixing, with a 30-minute UL 72 rating.
A safe certified for paper lets a USB stick or a drive melt long before its limit. The Master Lock L1200 is the only one to state, on top of its UL classification for documents, ETL verification for CDs, DVDs and USB drives; no box in this hub states protection for a hard drive.
Not necessarily: they are two distinct certifications. A light, unanchored fireproof safe is carried off without difficulty.
The certified duration is stated and corresponds to a standardized test. Beyond it, the protection ends.
Only if the safe is certified for digital media, whose destruction threshold is far lower than that of paper.
On some models the insulation absorbs moisture over time. A safe exposed to damp can lose performance.
No: the contents stay very hot and opening early exposes the paper to hot air. Let it cool completely.
Not automatically, and water from firefighting is a frequent cause of damage. Five of the six models in this hub state water resistance, not the BURG-WÄCHTER; none publishes an immersion depth or duration.
Yes: protection against fire says nothing about protection against being carried off. Anchoring is still necessary.
Fire resistance and burglary resistance are two independent certifications: a light fireproof safe is carried off. Paper certification does not protect a hard drive, whose threshold is far lower — and after a fire, let it cool completely before opening.
A characteristic has to come from four devices in five to hold a column. Below that, we would be lining up empty cells.
