IBM 49Y7424-RFB is a refurbished hard disk drive for adding 300GB of storage to a system that uses a SAS drive. Its 10K spindle speed and SAS interface are among the details identified for this specific model in the product listing.
The listing specifies a 300GB capacity and 15MM thickness, giving a clear description of the drive’s storage size and physical profile. The item is marked refurbished, so this is a restored product rather than a new drive. The model reference helps distinguish it from other IBM drive variants.
