Claim 10:
11. A storage system connectable to a host, comprising:
a first storage device that includes:
a first port;
a first nonvolatile memory; and
a first controller configured to:
encrypt, using a first media encryption key, data transmitted from the host and received through the first port; and
store the encrypted data in the first nonvolatile memory;

a second storage device that includes:
a second port;
a second nonvolatile memory; and
a second controller configured to:
encrypt, using a second media encryption key, data transmitted from the host and received through the second port; and
store the encrypted data in the second nonvolatile memory; and

a server that includes:
a third nonvolatile memory, the third nonvolatile memory storing a first key and a second key; and
a third controller configured to:
transmit the first key from the third nonvolatile memory to the first storage device without passing through the host, and
transmit the second key from the third nonvolatile memory to the second storage device without passing through the host, wherein

the first controller of the first storage device is configured to generate the first media encryption key using the first key and identification information of a user transmitted from the host, and
the second controller of the second storage device is configured to generate the second media encryption key using the second key and the identification information of the user transmitted from the host.
