Correct me if I'm wrong, but the 64mb uses 4k sectors and the 32mb uses 512b.
It's going in a Win 7 machine. Is there a reason to prefer one over the other? I didn't think the cache really made that much of a difference, and didn't know if the new 4k tech was better to avoid at the moment. Just wondering which to get. Just using it for storage. Thanks for any info!
