We are arguing about nothing. Live data (being accessed many times per day) stays on SSDs. The middle tier of data is a gray area and can go on SSDs or disk. But if you think that your FB or Youtube or Fidelity or Geico or SSN or IRS or Apple or Google data isn't sitting on a tape somewhere, you are extremely mistaken, because I was the one who wrote the tape control software they purchased from us.
Nobody's denying that the data makes it to tape eventually. What everyone finds hard to believe is your assertion that data is ever moved from tape back into warm storage during the ordinary course of business. Enterprises use tape for backup. They only read data off tapes after something goes very wrong, or periodically to verify that their backup process is actually working. But except after a catastrophe, data rea…
A researcher desires to download a 50 minute archived video. A request is sent from their laptop to a lookup table server. The lookup table contains the metadata for where that file is stored.
Then the request is passed to a media server which has an SSD and RAM large enough for receiving the actual media file. It opens a connection with the tape library. The tape library handles loading the media from tape to a staging server, which also has an SSD.
So totally the media file goes from tape, to staging SSD via hardwire, to main server's SSD over the network, to client's device over the network.
