The Small Computer System Interconnect (SCSI) adapter market is a legacy category in terminal decline, with a current global TAM of est. $48M. The market is projected to shrink at a 3-year CAGR of -14.5% as superior technologies like SAS and NVMe dominate all new system designs. The single greatest threat is technology obsolescence, leading to widespread supplier discontinuation and acute supply chain risk for organizations still dependent on legacy hardware. Proactive lifecycle management is no longer optional, but mandatory.
The global market for new SCSI adapters is contracting rapidly, driven by the near-total replacement of the interface in modern enterprise and client computing. Demand is now confined to maintaining legacy systems. The projected five-year CAGR is -15.2%, indicating a market that will become increasingly niche and difficult to source. The largest geographic markets are those with significant installed bases of older industrial, medical, or data center equipment, primarily North America, the EU (led by Germany), and Japan.
| Year | Global TAM (est. USD) | CAGR |
|---|---|---|
| 2024 | $48 Million | -14.5% |
| 2025 | $41 Million | -15.0% |
| 2026 | $34 Million | -15.9% |
The landscape is composed of a few legacy incumbents and a fragmented set of niche specialists. Barriers to entry are effectively infinite, as there is no viable business case for new entrants in a declining market.
⮕ Tier 1 Leaders * Broadcom Inc.: Inherited a dominant market position through its acquisition of LSI Logic; now primarily focused on managing the EOL process for its legacy SCSI products. * Microchip Technology Inc.: Owns the Adaptec brand, a historically significant player; continues to offer a limited range of SCSI cards but is consolidating its portfolio. * ATTO Technology, Inc.: A niche player focused on high-performance connectivity for the media & entertainment market, still offering specialized SCSI products for Mac and Windows workstations.
⮕ Emerging/Niche Players * Paralan: Specializes in SCSI extenders, converters, and cables for unique legacy configurations. * ISE, Inc.: Provides legacy storage solutions and bridge devices (e.g., iSCSI-to-SCSI). * Secondary Market Resellers: A fragmented global network of IT hardware brokers and refurbishers (e.g., World Data Products, Curvature) now handles a significant volume of transactions.
The price of a SCSI adapter is built from the controller ASIC, the printed circuit board (PCB), connectors, passive components (capacitors, resistors), and assembly/testing costs. As a mature product, non-recurring engineering (NRE) costs for the core silicon are fully amortized. Pricing for new, in-stock units from manufacturers is relatively stable but subject to inflationary pressure on base materials.
The true volatility exists in component availability and the secondary market. As manufacturers deplete their final inventory of controller ICs, they are forced to discontinue adapter production. This pushes all remaining demand to distributors and brokers, where pricing is dictated purely by scarcity and immediate need, decoupling it from the original bill-of-materials cost.
Most Volatile Cost Elements: 1. Legacy Controller ICs: Availability is near zero from primary sources. Broker pricing for critical EOL chips can fluctuate +100% to +500% quarter-over-quarter. 2. Multi-Layer Ceramic Capacitors (MLCCs): Subject to broad electronics supply/demand cycles. Prices have stabilized, down est. -20% from 2022 peaks, but remain a risk. 3. Gold Plating (Connectors): Connector costs are sensitive to gold commodity price fluctuations, which have seen est. +15% volatility over the last 12 months.
Innovation in this category has ceased; trends are centered on managing decline. * Aggressive Product Sunsetting (Q4 2022 - Present): Major suppliers, including Microchip and Broadcom, have accelerated EOL notices for their remaining Ultra320 and Parallel SCSI adapter families, shifting focus entirely to SAS/SATA/NVMe product lines. * Rise of Bridge Technology (2023): A growing niche market has emerged for "bridge" devices that convert modern interfaces like USB 3.0, Thunderbolt, or iSCSI to a legacy SCSI interface. These are used for data recovery and connecting to single legacy peripherals, not for production server workloads. * Shift to Refurbished Supply (2023-2024): Over est. 60% of enterprise demand is now fulfilled via the secondary/refurbished market, a significant shift from traditional distribution channels. This introduces quality and counterfeit risks.

Demand for SCSI adapters in North Carolina is low but persistent, driven by the need to maintain legacy systems within the state's established technology and research sectors. The Research Triangle Park (RTP) area, with its long history of R&D from firms like IBM and its concentration of universities and biotech labs, contains pockets of older, specialized equipment that still rely on SCSI. Additionally, the significant data center presence in the state (Apple, Google, Meta) may have residual, non-production systems requiring SCSI parts for data migration or archival access. Local capacity is limited to distribution and reseller presence; there is no manufacturing. Sourcing is entirely dependent on national distributors or the global secondary market.
| Risk Category | Grade | Justification |
|---|---|---|
| Technology Obsolescence | High | The technology is obsolete and has been superseded. No new development or investment is occurring. |
| Supply Risk | High | Key manufacturers have issued EOL notices. Supply is constrained to remaining inventory and a volatile secondary market. |
| Price Volatility | Medium | While overall demand is low, prices for specific, scarce models on the secondary market can be extremely high and unpredictable. |
| Geopolitical Risk | Low | Production is on mature, widely available semiconductor nodes. Low volume reduces significance as a geopolitical target. |
| ESG Scrutiny | Low | Low production volume and mature technology result in minimal ESG focus from regulators or activists. |
