Controller RAID Adaptec SmartRAID 3101E-4i, 1 GB, SAS/SATA, RAID 0/1/10, PCIe 3.0 x8, 12 Gbps, Low-Profile

The Interface card Adaptec SmartRAID 3101E-4i is an entry-level, low-profile PCIe RAID adapter that supports SAS and SATA drives with up to 12 Gbit/s transfer rates. Designed for deployments with a limited number of drives, it provides hardware RAID functionality and caching benefits without the complexity or feature set of full-size RAID controllers. The card supports RAID 0, 1, 1 ADM and 10 ADM and carries certifications such as CE, FCC and UL; its MTBF of 1,370,000 hours indicates long-term reliability for storage servers and workstations.

Advantages

The Adaptec SmartRAID 3101E-4i offers a compact, cost-effective hardware RAID solution that delivers SATA and SAS connectivity over a PCIe host interface, up to 12 Gbit/s throughput, and support for commonly used RAID levels (0, 1, 1 ADM, 10 ADM). Its high MTBF and industry certifications provide predictable reliability while keeping power and complexity low compared with full-featured RAID adapters.

Suitable for

• Small servers and entry-level storage systems
• Workstations requiring improved disk reliability and redundancy
• Environments needing SAS/SATA connectivity with limited drive counts
• Deployments that benefit from caching but do not require advanced cache backup

Key specifications

• Host interface: PCIe (low-profile)
• Output interfaces: SATA, SAS
• Maximum transfer rate: 12 Gbit/s
• Supported RAID levels: 0, 1, 1 ADM, 10 ADM
• Internal: Yes
• MTBF: 1,370,000 hours
• Certifications: CE, FCC, UL (and others)

How to use

Install the Adaptec SmartRAID 3101E-4i into an available low-profile PCIe slot on the host system, connect SAS or SATA drives to the card’s internal ports, and power on the system. Configure RAID arrays using the controller’s firmware/BIOS utility or management software provided by the vendor, selecting the required RAID level (0, 1, 1 ADM, or 10 ADM) and enabling caching as needed. Ensure drivers and firmware are up to date according to ADAPTEC documentation.

Recommendations

Use this adapter in systems with a limited number of drives where hardware RAID and caching improve performance and data protection, but advanced cache backup or higher-end RAID features are unnecessary. Verify compatibility with your server chassis and operating system, and follow manufacturer guidance for firmware and driver updates.
