Broadcom 3ware 9750-4i LSI00215 PCIe2.0 x8 4-Port Internal 6Gb/s SATA/SAS Hardware RAID Controller

Basic Parameter Table

Core Product Features

1. 3ware series entry internal hardware RAID card, independent RAID acceleration chip, built-in dedicated write cache, supports full hardware RAID redundancy schemes for enterprise storage.
2. Single SFF-8087 internal connector connects up to 4 internal 6G SAS/SATA hard drives/SSDs; PCIe2.0 x8 bandwidth matches high-speed disk array throughput demand.
3. Dual usable firmware modes:
   • IR RAID Mode: Native hardware RAID 0/1/5/6/10/50/60, automatic disk redundancy, hardware-level error correction, suitable for enterprise file servers requiring data redundancy.
   • IT Pass-through Mode: Can reflash pure IT firmware, OS fully controls each disk individually for ZFS/unRAID/FreeNAS NAS deployment.
4. Large white passive heatsink ensures stable 24/7 silent rack server operation; full-height & low-profile brackets included.
5. Internal hard drive hot-swap supported under both RAID and IT firmware modes.
6. Entry 4-drive internal RAID controller, balanced cost and performance, widely used for small business internal redundant storage and small 4-bay NAS after IT firmware flashing.

Application Scenarios

1. IR RAID deployment: Small enterprise 4-drive redundant file storage servers, office backup storage requiring hardware RAID fault tolerance.
2. IT flashed deployment: Mini 4-bay ZFS TrueNAS / unRAID media NAS, low-power home server internal disk expansion.
3. Not applicable: Mission-critical storage requiring power-failure cache protection (no CacheVault), external JBOD expansion (zero external ports).
