Same 3.5-inch bay, same SAS 12Gb/s interface, double the capacity. If your 2TB drives are filling up and you'd rather seat one 4TB than two 2TBs, this is your move. 7200 RPM, native 512-byte sectors, hot-swap ready. Pull the old drive, seat this one, let the array resync. Keeps your ThinkSystem running without booking a service window
