This doesn't have anything to do with ByteStreams.toByteArray. 300 MB is 
generally too much to be loading into memory, and it isn't necessary at all in 
your example. What you should be doing is this:

    CRC32 crc32 = new CRC32();
    File file = new File("test.zip");
    long checksum = ByteStreams.getChecksum(
        Files.newInputStreamSupplier(file), crc32);
