What it was

Quantum Fireball EX hard disk family is recorded in the 1998 Storage research cohort under Quantum. The current display name and classification are normalization proposals.

Source product name
Quantum Fireball EX family
Source model number
3.2, 5.1, 6.4, 10.2, 12.7 GB capacities
Source manufacturer
Quantum Corporation
Research scope
desktop PCs; IDE/Ultra ATA; OEM sample and distribution channels

Why it existed

manufacturer stated

Quantum addresses higher-capacity IDE desktop storage and OEM demand

Intended users: desktop OEMs and PC users

Engineering response: Fireball EX family with IDE-only interface and multiple capacities

Evidence and limits

Quantum Fireball EX announced with 12.7GB model · June 9 report

Contemporary report gives capacity/interface and OEM sample context around the June announcement.

Source is contemporary reporting tied to Quantum information; no neutral storage benchmark retained.

What difference it made

Comparable benchmark evidence has not been established for this record. Missing results do not imply poor performance.

Release evidence

The year above is a research-cohort label. Announcement, production, shipment and retail availability are distinct events.

Proposed event
product announcement and mass production
Proposed timing
1998-06-08 · exact precision
Assessment
proposed

Verified June announcement plus stated July mass production supports a family proposal while preserving missing first-shipment day and geography.

Open questions and review

First shipment date, OEM/distribution geography, per-capacity SKU identity.

No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.

family variant overlap · follow up

Fireball EL and Fireball EX are different named HDD families but the frozen records are family-level rather than per-capacity SKU records; their capacities must not be retroactively treated as separate candidates without a new scoped scout run.

Audit source · Form 10-Q product discussion

Quantum reports the Fireball EL and EX as named new products and gives family-level production timing rather than a complete per-SKU launch register.

Follow-up: Keep each as a family-level frozen record; require separate evidence and a declared granularity decision before any SKU expansion.

evidence gap · follow up

Fireball EX has a dated June 8 announcement and July mass production; the frozen evidence does not state a precise first commercial shipment or channel geography.

Audit source · dated June 9 1998 report

The report gives the June 8 announcement and says the series would enter mass production in July; it does not document a day of commercial availability.

Follow-up: Retain the dated announcement separately from production timing and seek OEM or distribution shipment evidence if the cohort rule requires commercial shipment.

Original intake sources

These notes preserve the state at intake. Later verification is shown under Release evidence above; an original note saying verification had not occurred is not the current assessment.

Original research note

Typed events: Japanese Quantum/PC Watch report says Fireball EX was announced June 8, 1998 and mass production would begin in July; Quantum's filing corroborates June announcement and July mass production. Preserve family and capacity range; exact first shipment day and regional channel scope remain unknown.
