We supply all mainstream form factors including 2.5″ SATA, M.2 2280 (SATA & NVMe), M.2 2242, U.2, and E1.S/E1.L for enterprise applications. Custom form factors can be sourced upon request.

Both. SATA III (6 Gb/s) SSDs for cost-effective storage upgrades, and NVMe PCIe Gen3/Gen4/Gen5 SSDs for high-performance workloads. We can advise on the best interface for your use case.

Consumer-grade: 120GB to 4TB. Enterprise-grade: 480GB to 30.72TB. We source from Samsung, WD, Seagate, Intel, Lexar, Biwin, Netac, and other brands. Specific capacities depend on brand and model availability.

We supply both. All products are clearly labeled as “Brand New” or “Refurbished/Used.” New units come with full manufacturer warranty. Refurbished units are tested and graded (Grade A/B/C) with our own warranty.

TBW varies by model and capacity. Consumer NVMe SSDs typically range from 150 TBW (500GB) to 2,400 TBW (4TB). Enterprise SSDs offer significantly higher endurance with DWPD (Drive Writes Per Day) ratings of 1-3 DWPD for read-intensive and 3-10 DWPD for mixed-use workloads. We provide full spec sheets upon request.

Yes. Through our partnerships with Chinese manufacturers (Biwin, Netac, Galax, etc.), we can arrange OEM/ODM production with your brand label, custom packaging, and firmware configuration. MOQ typically starts at 500 units.

Brand new SSDs carry the manufacturer’s standard warranty (typically 3-5 years). Refurbished units come with our 90-day to 1-year warranty depending on grade. Extended warranty options are available.

Yes. We offer sample units for evaluation. Sample cost is typically the unit price plus shipping. Sample fees can be credited toward your first bulk order. Lead time for samples is 3-7 days.

All SSDs undergo incoming inspection including: firmware verification, SMART data check, capacity validation, sequential & random read/write benchmarking, and physical inspection for tampering. We provide test reports with each shipment.

In-stock items: 3-5 business days for processing + shipping time. Out-of-stock or OEM orders: 2-4 weeks depending on quantity and customization. We maintain safety stock for popular models.

Enterprise SSDs from Samsung, Intel, and WD support TCG Opal 2.0 and IEEE 1667 self-encrypting drive (SED) standards. Consumer models vary by brand. We can confirm encryption support for specific models upon request.

CMR (Conventional Magnetic Recording) drives offer consistent write performance and are preferred for RAID, NAS, and enterprise use. SMR (Shingled Magnetic Recording) drives are cheaper but have slower sustained write speeds. We primarily supply CMR drives for business customers and can source SMR for cost-sensitive archival applications.

Yes. Helium-filled drives (typically 12TB and above) offer lower power consumption, reduced heat, and higher capacity in a standard 3.5″ form factor. We supply helium HDDs from Seagate Exos and WD Ultrastar series.

5400 RPM (energy-efficient, NAS/archive), 7200 RPM (standard performance, enterprise), and 10000/15000 RPM (high-performance SAS, limited availability as these are being phased out in favor of SSDs).

Refurbished enterprise HDDs from reputable suppliers can be reliable for non-critical workloads, backups, and testing environments. We grade refurbished drives (Grade A: under 10,000 power-on hours, Grade B: 10,000-30,000 hours) and provide SMART health reports. For mission-critical production, we recommend new drives.

New enterprise HDDs typically have MTBF (Mean Time Between Failures) ratings of 2.0-2.5 million hours. We provide full specification sheets including MTBF, URE (Unrecoverable Read Error) rates, and workload ratings for each model.

For new drives, firmware is the latest version from the manufacturer. For refurbished drives, we can often accommodate specific firmware requests for compatibility with existing arrays. Custom firmware flashing is available for large orders.

Yes. All refurbished drives undergo certified data erasure (NIST 800-88 compliant) before resale. We provide data destruction certificates upon request. Physical destruction services are also available.

Both SATA (6 Gb/s) and SAS (12 Gb/s). SATA drives are suitable for NAS, desktop, and entry-level server use. SAS drives are for enterprise servers and storage arrays requiring higher throughput and dual-port redundancy.

All HDDs are packed in anti-static bags with shock-absorbing foam in reinforced cartons. For international shipments, we use double-wall cartons with corner protection. Pallet shipping is available for large orders. We insure all shipments.

Currently up to 24TB (Seagate Exos X24, WD Ultrastar DC HC580). Higher capacities (28TB+) are emerging and can be sourced as they become available from manufacturers.

Yes. We support mixed orders with different capacities, brands, and types in a single shipment. This is common for customers building heterogeneous storage pools or replacing drives across multiple systems.

Both DDR4 and DDR5. DDR4 remains widely used in existing servers and desktops (up to 128GB per module). DDR5 is the current generation for new builds (up to 128GB per module, with 256GB modules emerging). We also supply DDR3 for legacy systems.

Yes. ECC (Error-Correcting Code) memory for servers and workstations (RDIMM, LRDIMM, UDIMM ECC). Non-ECC unbuffered memory (UDIMM) for desktops and consumer systems. We can also source registered (RDIMM) and load-reduced (LRDIMM) for high-capacity server configurations.

Yes. We regularly fulfill bulk CPU orders for data center refreshes and expansions. Volume pricing is available for 10+ units. We can also arrange phased delivery to match your deployment schedule.

All CPUs are shipped in original anti-static trays or protective clamshell cases. For LGA sockets (Intel), the pins are on the motherboard so CPU shipping is straightforward. For PGA sockets (older AMD), we use reinforced pin-protective carriers. All shipments are insured.

Yes. We can source matched CPU + motherboard combinations to ensure compatibility. This is particularly useful for customers building new servers or workstations from scratch. Bundle pricing often provides additional savings.

Used server CPUs typically cost 50-80% less than new equivalents. For example, a used Intel Xeon Gold 6248R may cost 60-70% less than a new 5th Gen Xeon with similar core count. The exact savings depend on generation, core count, and market availability.

Absolutely. Tell us about your workload (virtualization, database, AI/ML, web serving, etc.), budget, and existing infrastructure. Our team will recommend the best CPU option balancing performance, power efficiency, and cost.

Yes. OEM CPUs pulled from Dell, HPE, Lenovo, and other branded servers are available. These are genuine manufacturer CPUs that were originally installed in OEM systems. They function identically to retail/tray versions.
