What they don’t tell you about all the new technology
Some new technologies have side effects which decrease data redundancy. Such technologies are:
- NTFS compression
- Windows Vista/7 vs. Windows NT/2000/XP complete format
- TRIM on SSDs
- ZFS deduplication
- Volume-level NTFS compression never became widespread among home users.
- As Windows Vista and then Windows 7 become widespread, the number of cases when data is lost irreversibly due to reinstallation increased. You can recover some data after XP reinstallation, but not after Vista/7 reinstallation with a complete format.
- SSDs with TRIM are not widespread enough (yet) to notice that data recovery software does not properly work with them.
- As for ZFS-based NASes, then on the one hand they are not widespread among the home users, on the other hand - even the first installations did not yet reach the end of their service life.
