Broadcom LSI SAS3041E-R 3041E-R PCIe x4 HBA Card (4 Internal 3Gb/s SATA/SAS, IT Mode Only, No RAID)

Basic Parameter Table

Core Product Features

1. Entry-level pure IT HBA host bus adapter, LSI SAS3041E-R chip, only supports pass-through mode, no hardware RAID function, ideal for NAS, ZFS, unRAID, FreeNAS disk expansion.
2. Four independent onboard internal SATA interfaces, directly connect up to 4 internal SATA hard drives / SSDs; PCIe 2.0 x4 bandwidth fully meets 3Gb/s low-speed disk throughput requirements.
3. Single fixed IT pass-through firmware, OS fully controls each hard disk independently, no RAID card redundant write cache, no risk of cache loss after power failure.
4. Compact low-profile PCB, small built-in chip heatsink, fanless silent operation, compatible with mini ITX, small chassis, home server low-noise environments; full-height & low-profile brackets included.
5. Support internal hard drive hot-swap under IT mode, all storage devices directly exposed to host operating system.
6. Low-cost entry SATA expansion card, the preferred choice for small 4-drive home NAS, media storage, low-power mini server disk expansion.

Application Scenarios

1. IT pass-through deployment only: Mini 4-bay ZFS TrueNAS / unRAID / FreeNAS home media storage, low-power mini ITX server internal disk expansion, small office low-capacity file storage.
2. Not applicable: Enterprise hardware RAID array construction, database storage requiring RAID redundancy, high-speed 6Gb/s SAS disk expansion.
