The only one listed in the Lenovo parts list is the Samsung 950 (FRU 00UP414) which is a PCI drive and the 1TB model is announced but not available yet. I would expect something like the SanDisk X400 model (SATA) would be OK ($275 from Amazon), but I have never tried it so I cannot guarantee it would work. If it were me, I would buy from somewhere where I could return it if there was a compatibility issue. This is not a recommendation for a particular brand. There are other similar drives available from other manufacturers.
