The PEXSAT34RH 4-Port PCI Express SATA III Controller Card adds 4 AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections to high-performance hard drives and Solid State Drives (SSDs), all from a single PCIe expansion slot. The PCIe SATA controller card features Port Multiplier (PM) support on each port, which enables multiple SATA drives to be connected through one of the ports over a single cable, for a total of 7 simultaneous drive connections - (Connect up to 4 drives through PM on one port, and a single drive to each of the remaining 3 ports). Supporting RAID 0, RAID 1 and 1+0 configurations, this versatile PCI Express SATA RAID card includes an onboard heatsink to dissipate heat build-up, to help maintain peak operating performance even at full capacity. This PCIe SATA 6gbps card is backed by a 2-year warranty and free lifetime technical support. Maximize system capability by remaining backward compatible with older SATA (I/II) drives, while adding the outstanding speed of SATA III connectivity. Ensure reliable SATA host connections with a passively cooled expansion card. Use the card in virtually any computer system, regardless of chassis form factor. Upgrade an older PCIe-based system to SATA 6Gbps capability, to better utilize faster SATA drives. Add more internal SATA ports to a computer system, to connect additional storage drives and/or optical drives. Provide optimized off-site back-ups/vaulting, through built-in RAID 1 capability. Perfect for multi-drive internal RAID storage solutions.

Do you have you a question about the 4 Port PCI Express SATA III 6Gbps RAID Controller Card with Heatsink?

Q: Does this controller allow hot swap of SATA drives? I'll be using a Supermicro CSE-721 case.
Answer by Website User on 23rd December 2021
Should be fine, you can plug a sata drive in to a running PC and it is detected by the OS and works fine. Circuitry in a hotswap bay will be adapted for this action anyway as part of its functionality.
