That is > surprising, and ridiculous. Not really. The NTFS driver is a FUSE module and it is very much CPU bound. If the partition is encrypted then that's more CPU needed. Regarding scrubbing sensitive data: unfortunately for you, the only way to reliably do that on flash-based SSDs is to issue the ATA secure erase command which will zero out the whole drive. But if the partitions are encrypted then throwing away the keys (clear/reset TPM for bitlocker keys) should be sufficient for most use cases. -- \m/ (--) \m/ _______________________________________________ Discuss mailing list Discuss@lists.blu.org http://lists.blu.org/mailman/listinfo/discuss
