Lenovo ThinkSystem ST550 2.5" SATA/SAS 4-Bay Backplane Kit – Media Bay Conversion (7XH7A05908)

You've got 5.25-inch bays sitting empty and you need 2.5-inch SATA or SAS drives in there. This conversion kit swaps those wide bays for four proper 2.5-inch slots. You get the backplane, all the cabling, and the drive-bay cage — everything to go from 'I wish I had more 2.5" bays' to 'they're in and spinning.' One thing to know: you'll need a RAID controller or HBA already wired into the ST550 for the drives to be recognised. Only two sets on the shelf right now, so if this is your fix, grab it today
