In addition, newer SSD will have even more capacity than existing disk drives while at the same time offering storage in a smaller and smaller physical size. This capacity is comparable to that of tapes. Let’s do a quick comparison of tape and disk storage to consider the advantages of each: Capacity “As of 2011, the highest capacity tape cartridges (T10000C) can store 5 TB of uncompressed data” (source Wikipedia), while hard drives have followed Kryder’s law (much like Moore’s law) and doubled areal density every two to four years putting disk drive capacity currently somewhere around 4 TB.
But even with these advantages it seems that backups to disk (and dare I say to the cloud?) have so many more advantages. I realize that there are still advantages with tape when it comes to large volume backups and the ability to physically move the backup media to an offsite location. I think what they were asking is whether backup to tape is the kind of legacy technology today that we see with VHS-there are still a few out there but the technology is on its way out. I was frequenting Spiceworks earlier today and came across a post asking if “tape was legacy”.
