Import 3.5"Usb Hdd External Enclosure — Buy in Bulk from Supplier in China

The 3.5-inch USB HDD external enclosure from Protech Soures Limited is a desktop-format drive caddy that converts internal SATA hard drives into externally accessible storage via USB 3.0. The enclosure accepts standard 3.5-inch form factor drives, the size commonly used in desktop PCs and NAS units, and interfaces with host systems through a USB 3.0 Type-B to Type-A cable for broad compatibility. Tool-free installation indicates a snap-on or sliding chassis design that eliminates the need for screwdrivers during drive mounting or replacement.

Constructed with a robust chassis, the enclosure provides physical protection against dust ingress and minor impact damage, though the specific material (typically ABS plastic or aluminium for this product segment) is not stated by the supplier. USB 3.0 support delivers theoretical transfer rates up to 5 Gbps, with practical sequential write speeds typically limited by the mechanical hard drive rather than the interface. The enclosure is universally compatible across operating systems, which implies UASP (USB Attached SCSI Protocol) support or at least standard mass-storage class drivers for Windows, macOS and Linux environments.

Typical applications include bulk data backup, media archiving, expanding gaming console storage and repurposing retired internal drives for external use. Buyers span IT departments, system integrators, data recovery services and consumer electronics retailers. Trade terms are not specified in this listing; Protech Soures Limited indicates flexibility for small and bulk orders, but exact MOQ, Incoterms and payment methods require direct confirmation. The supplier is located in Shenzhen's Longgang district, a major electronics manufacturing hub, though no factory audit or verification status is disclosed.

Protech Soures Limited is registered in Shenzhen, Guangdong Province, China, with an address at J201 Meidixuan Phase 1 in the Wankecheng Bantian area of Longgang District. This location places the supplier within one of China's most concentrated electronics manufacturing corridors, though the listing does not indicate whether Protech operates its own production facility or functions as a trading company. The supplier tier is marked as "imported" and the trust tier as "harbor", which are platform classification labels rather than independent verification credentials.

The supplier profile shows a response rate of 0.00 percent with zero average response hours, indicating no recorded buyer engagement through the platform's messaging system. This absence of response data is a notable gap for importers assessing supplier reliability. No information is provided about years in operation, employee count, annual revenue, factory size, quality management certifications (ISO 9001, etc.), or named client references. Buyers should conduct independent due diligence, request company registration documents, and verify physical premises before committing to orders.
