BROADCOM SAS 9305-24i Storage Controller - 24 Internal Ports - SATA 6Gb/s / SAS 12Gb/s - Low-Profile PCIe 3.0 x8 HBA

The Broadcom SAS 9305-24i is a high-performance host bus adapter (HBA) designed for enterprise storage environments. It provides 24 internal ports via six SFF-8643 (Mini-SAS HD) connectors, supporting both SAS (12Gb/s) and SATA (6Gb/s) devices. With a PCI Express 3.0 x8 host interface, this low-profile MD2 card delivers exceptional throughput and scalability for demanding applications.

Advantages

Unlock maximum storage performance with the Broadcom SAS 9305-24i. Its 24 native ports eliminate the need for expanders in many configurations, reducing latency and complexity. The LSI SAS3524 controller ensures reliable data transfer at up to 12Gb/s per lane, while the low-profile form factor fits seamlessly into space-constrained servers. Backed by a >2,000,000-hour MTBF and broad OS support, this HBA is built for 24/7 operation.
