The Lenovo ThinkSystem RAID 730-8i is a RAID controller designed for those looking to manage their data storage with efficiency and reliability. It supports RAID levels 0 and 1, which are useful for either performance (RAID 0) or data redundancy (RAID 1). However, it lacks support for more complex RAID levels such as RAID 5 or RAID 10, which may be a drawback for users seeking advanced data protection and performance options.

With an interface type of PCI Express 3.0 x8 and a controller type of 12Gb/s SAS, it ensures fast data transfer rates and is suitable for modern servers and workstations. The card comes with 2GB of flash memory, which is beneficial for improving performance and caching data. The host interface supports hot-swapping, allowing you to replace drives without shutting down the system, a crucial feature for maintaining uptime in critical environments.

Compatibility-wise, it integrates well with SAS and PCI Express x8 hardware, making it versatile for various systems. Being a product from Lenovo, a reputable brand, adds to its reliability and support options. The limited RAID level support may not meet the needs of users looking for more comprehensive RAID configurations. This RAID controller is a solid choice for users needing basic RAID functionalities with good performance and reliability, but might not be suitable for those requiring advanced RAID setups.
