Why is the displayed capacity lower than the nominal capacity?

This is due to calculation differences: manufacturers use decimal (1GB=1000MB) while OS uses binary (1GB=1024MB).

AI-Powered supplier vetting

SummaryShenzhen Topfine Technology Co., Limited is a China-based limited company described across the records as both a trading company and manufacturer/factory, supplying flash drives and related storage products. It reports broad customization and ODM capabilities, new products within the past year, extensive export coverage, and an off-peak lead time within 15 working days. However, the available quality and service-control evidence is weak: no written corrective-action or complaint-handling procedures are reported, quality assurance and traceability statuses are unknown, and quality-control test equipment is recorded as zero. A TUV Rheinland audit record is present, but its evaluation result is recorded as 0 and the report validity ended in 2025. Financial information is represented only by years, without substantive financial performance evidence. No customer cases or named-brand OEM references are provided.

Supplier typeThe supplier is identified as Shenzhen Topfine Technology Co., Limited, a China-based limited company. Its records classify it as both a trading company and manufacturer/factory, while its stated business scope includes electronic products, computer peripherals, U disks, and import/export activities; another record lists medical-device-related licensed projects, creating some scope inconsistency.

After-Sales capabilityThe supplier reports no written procedures or records for corrective and preventive actions or effective customer-complaint handling. This is explicit evidence of a documented service-process deficiency.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, indicating some product-development capability. It also reports no available SDK, but the absence of an SDK is not by itself evidence that its general innovation capability fails the field.

Production capacityThe supplier is described as a manufacturer/factory and reports production of storage-related products including HDDs, SSDs, micro SD cards, USB flash drives, and memory cards, with stated output of 5,000,000 pieces. However, its quality-control test-equipment quantity is recorded as zero, while quality assurance and traceability statuses are unknown, weakening confidence in production-control maturity.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also states that it provides ODM services. These records directly support broad customization capability.
