Buying Guide

Match interface to your motherboard

Confirm whether you need PCIe add-in cards or a mini RAID module to ensure physical and BIOS compatibility with your system

Check supported protocols

Choose controllers explicitly supporting SATA, SAS or both depending on your drives; LSI and Dell models often list SAS/SATA support

Consider port count and expandability

Select a card with enough ports (for example six- or eight-port options) to accommodate current drives and any planned additions

Evaluate controller chipset

Chipsets such as ASM1166 and LSI variants affect performance and OS driver support—confirm driver availability for your OS

Assess cache and RAID level support

For hardware RAID features and write performance, review whether the controller includes cache and which RAID levels are supported
