HOLA, TENGO UNA ALIENWARE AREA 51M R2 Y REVISE Y NO VEO LOS OTROS DOS PUERTOS EN DONDE VA EL DISCO HHD, HABRA QUE AGREGAR PLACA PARA DOS M.2 MAS?'
Thanks crimsom, very helpful. When you say 'if one of the RAID 0 drives fails, both drives have to be replaced'.  Why is this.... would only one drive have failed?  i realise that the drive may need to be formatted, but would it have to be replaced?  i have a the same ordered: I was going to swap out the 2 512mb for4 2 x 2 tb units.  i was going to leave thje OS drive as is.   Is there any mileage in changing the OS drive and the second M.2 to Raid 1 (if this is possible).  I realsie that the storage for C would only be 512mb.... not sure if this is worthwhile...  Any thoughs greatly appreciated. Matt
