The manufacturers of most different technologies would like to jump on the archive memory market and propagate their solutions as WORM storerooms. While optical storage media can usually only be written to once, hard disks, solid-state disks (SSD) or tapes can be changed, deleted and rewritten as often as desired.
In order to be able to use these storage media in long-term archiving, they are configured as write-once media by means of software, which is why they are also referred to as softWORM. In the course of the DSGVO, many of the manufacturers now declare their conformity and thus uncover their actual weakness - it is not a trueWORM file system, which is unchangeable as in storage systems with optical data carriers (such as CD-R, DVD-R, BD-R or ODA), but an artificially created WORM file system, which can be manipulated with the right key, under certain circumstances.
