High-performance PCIe cable for server and workstation use, designed to link U.2/U.3 NVMe drives and deliver high-bandwidth connections. Reliable routing keeps multi-drive workstations and racks tidy and dependable. Is the KALEA-INFORMATIQUE PCIe 5.0 Cable the right choice for dual NVMe setups?
⚡ At a Glance
- • Data Throughput: Stated PCIe 5.0 throughput of 32GB/s in an x8 configuration, with backward compatibility
- • Best for: System builders and IT professionals wiring dual U.2/U.3 NVMe SSDs or RAID arrays
- • Not ideal for: Users without MCIO or SFF-8639 ports or those needing USB or hot-swap front bays
MCIO 8i 74-pin to two SFF-8639 68-pin split cable supports U.2 and U.3 NVMe SSDs and includes a Molex power connector. Backwards compatibility with PCIe 4.0 and 3.0 allows use across older platforms.
Blazing transfer rates - thanks to PCIe 5.0 x8 support
PCIe 5.0 signalling permits very high data rates, with a stated maximum of 32GB/s in an x8 configuration and native compatibility with PCIe 4.0 and 3.0 hosts.
Faster NVMe-to-host transfers reduce large file copy times and speed RAID rebuilds, improving workflow for heavy I/O tasks.
Dual NVMe connections - with MCIO 8i to 2x SFF-8639 splitting
MCIO 8i 74-pin connector mates to a compatible host port and splits into two SFF-8639 68-pin connectors, each addressing a separate U.2 or U.3 NVMe channel.
Two-drive setups become straightforward for RAID or expanded storage without extra adapter cards, simplifying chassis cabling.
Direct power for drives - with an integrated Molex connector
An onboard Molex power connector supplies the necessary drive power for U.2/U.3 NVMe SSDs rather than relying solely on host board power headers.
Powering NVMe drives directly avoids separate adapters and helps keep rack or tower installations cleaner and more reliable.
✨ The 4 Key Reasons for KALEA-INFORMATIQUE PCIe 5.0 Cable
- PCIe 5.0 compatibility - Ensure future-proof bandwidth for next-generation NVMe SSDs and large file transfers
- MCIO 8i 74-pin connector - Direct host connection without bulky adapters or extra cards
- 80 cm cable length - Easier routing in racks and mid-tower builds with cleaner cable management
- Integrated Molex power - Provides direct power for U.2/U.3 drives without adapters
