Can someone explain the differences betweem the Ulrabay slim and Ultrabay enhanced? If I understand them correctyly, either will work with the R51/R52 but the T42/T43 requires the slim. Is this true? When I called Lenovo they said the R52 had to use the slim, but I don't think that's right.

Thanks,
Eric

R51/52 can use ultraslim (9.5mm) devices but can also use utrabay enhanced devices (12.7mm). T4x can only use ultraslim devices.

Is there a benefit to one over the other (other than cost)?
