Ports of ASA5510-SEC-BUN-K9

Are there two kind of ASA5510-SEC-BUN-K9 or one type.Because I found one with 5 FastEthernet and one with 2*1000 and 3*10/100.
And if there is only one type of ASA5510-SEC-BUN-K9 , which ports are 1000 and which ports are 10/100?Has it been written under the port or not?
