The base of claim 1, wherein the first and second base members are formed using a stamping or deep drawing process. 3. The base of claim 2, wherein the sheets forming the first and second base members have different thicknesses. 4. The base of claim 1, wherein the first thin bottom portion defines the component support structure. 5. The base of claim 1, wherein: the first thin bottom portion forms the component support structure; and the second base member includes a central opening exposing the component support structure. 6. The base of claim 1, wherein the rotary component comprises an actuator assembly or a spindle assembly. 7. The base of claim 1, wherein the second portion of the first base member forms a side wall. 8. The base of claim 1, wherein: the first base member includes an edge having a first slot portion; and the second base member includes an edge having a second slot portion, wherein the first and second slot portions form a first U-shaped slot. 9. The base of claim 1 including an adhesive layer joining the first portion of the first base member to the second base member. 10. The base of claim 1, including a core layer of vibration dampening material between the first portion of the first base member and the second base member. 11. A data storage system including: the base of claim 1; data storage medium; and a top cover joined to the base and enclosing the data storage medium. 12. A base for use in a disc drive storage system comprising: a first base member formed of a single sheet of material and including first and second portions; a second base member formed of a single sheet of material and joined to the first portion of the first base member to form a thick base portion, wherein the second portion of the first base member is separated from the second base member to form a first thin bottom portion; and a layer of vibration dampening material between the first portion of the first base member and the second base member. 13. The base of claim 12, wherein the sheets forming the first and second base members have different thicknesses. 14.
