Qualstar Corporation

Qualstar Corporation, founded in California in 1984, is an American manufacturer specializing in data storage solutions and power supplies. The company's core mission revolves around delivering secure, reliable, and cost-effective data preservation and archive infrastructure. While the company completed its legal reincorporation from California to Nevada in early 2026, its operational headquarters remain in Camarillo, California.

Qualstar's key product offerings include a range of magnetic tape libraries designed for long-term data preservation, backup, disaster recovery, and archiving. These include the Q-Series libraries (Q8 Entry, Q24 Compact, Q40 Mid-Enterprise, Q80 Enterprise) and the Q1000+ enterprise tape library. The company also provides high-efficiency open-frame power supplies under its N2Power brand, serving various electronic equipment markets. Qualstar's solutions cater to resellers, system integrators, and original equipment manufacturers (OEMs) across sectors such as telecom/networking, audio/visual, industrial, gaming, and medical industries.

As of early 2026, Qualstar Corporation has undertaken significant corporate actions, including a 3-for-1 forward stock split and the aforementioned reincorporation to Nevada. The company reported Q1 2026 revenue of $1.43 million and continues to focus on strategic initiatives such as the launch of its Q1000+ enterprise system and efforts towards a potential uplisting to a major exchange. Led by CEO Steven N. Bronson, Qualstar positions itself as one of the last independent tape library manufacturers, emphasizing ransomware protection through air-gapped tape and offering solutions with a low total cost of ownership for archive storage.
