Ensure you have the appropriate NVMe RAID FoD license, as only Intel-branded NVMe SSDs are supported for RAID configurations. Additionally, verify that you are using Lenovo-qualified NVMe drives for compatibility and consider updating your firmware with the latest Lenovo Bootable Media Creator ISO. [community thread]
If you're experiencing low write speeds of 15-20 MBps, this may be expected due to the cacheless nature of the 5350 controller, which operates in write-through mode. To potentially improve performance, you can enable the drive cache using the MegaRAID BIOS interface or storcli commands. For significant speed enhancements, consider upgrading to a controller with a cache module. [community thread]
First, prioritize backing up any accessible data from the disk. Then, check the disk's role in the system using the XCC interface to determine if it's part of a RAID array or a standalone JBOD. If it's part of a RAID, replace the failed disk and allow the array to rebuild; if it's standalone, replace the disk and reconfigure it as JBOD or a RAID 0 array, then restore your data.

The Lenovo ThinkSystem ST550 does not provide standard SATA power leads from the power supply. Instead, you need to use the proprietary Tape & ODD power harness, specifically the 01KN091 or 03HC016 cables, to supply power to SATA drives. [community thread]
The NVMe U.3 drives require a direct PCIe x4 connection to the motherboard, rather than routing through the SAS/SATA RAID controller. Ensure that the backplane ports for the NVMe disks are configured to use PCIe lanes x4, while the SAS/SATA devices can utilize the RAID controller. [community thread]
