I'm not sure why people still need tape storage or hybrid SSD and tape storage, is it because of banking financial transactions recording requirements since the SSD storage now has similar or better storage capacity? The reported storage size for the hybrid MED is 72TB and Micron now has 60 TB for single SSD drive [1]. Huawei has even higher storage capacity with reported 128 TB in a single SSD drive [2]. [1] Micron launches 60TB PCIe gen5 SSD with 12GB/s read speeds: https://news.ycombinator.com/item?id=42122434 https://news.ycombinator.com/item?id=42122434 [2] Huawei unveils its OceanStor A800 AI-specific storage solution; announces 128TB high-capacity SSD: https://www.datacenterdynamics.com/en/news/huawei-unveils-its-oceanstor-a800-ai-specific-storage-solution-announces-128tb-high-capacity-ssd/ https://www.datacenterdynamics.com/en/news/huawei-unveils-it...

Size per dingus is somewhat irrelevant to the use case: what's it matter if you buy 10 things that take up a rack or 20 things that take up a rack - how much did it cost to store all of your data at the speed you needed? Modern tape still has extremely good $/TB. If you have a LOT (and I don't just mean a fews 100s of TB) of data you need to keep but don't need to be able to access all of it constantly then tape can still save you a metric boatload of money on TCO vs SSD or HDD. Dual tier systems are for when a small amount of that data may be hot at any given time (like you say, financial often has a lot of active data in a pool of tons of inactive data they can't throw out. Medical is another example). Rather than manual manage this you just run a 2 tier system that automatically bumps things in and out of high $$$, high performance storage banks to low $, high capacity storage banks transparently.
