Why is the capacity displayed on the computer smaller than the original capacity?

In factory, we use 1000KB=1MB for calculate, also we use a little space as the Bad Bolck Management software for SSD's stable using, the real capacity will be: Capacity x 0.93. Factory default setting :1GB=1000MB=1000000KB=1000000000B. Computer system setting:1GB=1024MB=1048576KB=1073741824B.

What is the difference between SATA I, SATA II and SATA III?

SATA I runs at 1.5 Gb/s with max speed 150MB/s. SATA II runs at 3.0 Gb/s with max speed 300MB/s. SATA III runs at 6.0Gb/s with max speed 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.

AI-Powered supplier vetting

SummaryThe supplier operates across device manufacturing, integrated-circuit design and sales, electronic components, display devices, software, technical services, and technology development. It reports OEM service for well-known brands, six production lines, 100% finished-product inspection, eight quality inspectors, and broad customization capability. Certifications include ISO9001:2015, ISO45001:2018, ISO14001, BSCI, and CE. However, no SDK is available; corrective-action, complaint-handling, finished-product inspection, and supplier-assessment procedures lack written records or records of execution. The supplier has no effective manufacturing subcontractor contract, inventory, overseas warehouse, overseas branch or agent, or overseas showroom, and has not participated in offline trade shows. Financial information is limited to year labels, preventing a substantive assessment of financial strength. Customer-specific cases are not provided.

Supplier typeThe supplier combines device and electronic-component manufacturing with integrated-circuit design and sales, software development, and technical services. It also reports OEM service for well-known brands, indicating a manufacturer and technology-service supplier rather than only a trading intermediary.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, BSCI, and CE certifications. These explicitly cover quality, occupational health and safety, environmental management, social responsibility, and product compliance.

After-Sales capabilityThe supplier has procedures for corrective and preventive action and customer complaints, but no written records; its service-capability assessment procedure also has no records. It has no overseas agents or branches and offers overseas services in zero countries, which limits demonstrated after-sales coverage.

R&D capabilityThe supplier reports integrated-circuit design, technology development, consultation, exchange, transfer, engineering research, software development, and display-device manufacturing. However, it explicitly has no available SDK, so the evidence supports technology-related capability but not a complete developer-platform offering.

Production capacityThe supplier reports six production lines, 100% finished-product inspection, eight quality inspectors, and raw-material traceability. Offsetting limitations are no inventory capability and no valid manufacturing-capacity contract with related subcontractors, creating gaps in supply continuity and subcontractor governance.

Customization capabilityThe supplier explicitly supports customization from samples, minor customization, full customization, customization from designs, and flexible customization. This is direct evidence of broad product-design and modification flexibility.
