We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Just curious, the durability of a SSD (relative to HDD) is driven by the amount of writes to the NAND Layer Cells. I've come across products from Kioxia and Solidigm+SK HYNIX on read-only optimised NAND SSD for enterprise/hyperscaler.

Wouldn't that make sense for clients to pivot towards these types of SSD for cold-storage when price decline fast enough.

And with HDD, the speed be a consideration when running High-Performance Compute/AI stuff.

Designed for modern IT infrastructures, 24G SAS (SAS-4) doubles effective bandwidth over 12Gb/s SAS (SAS-3). Featuring Kioxia’s 5th generation BiCS FLASH™ 3D flash memory, the PM7 Series delivers sequential read performance of up to 4.2Gigabytes (GB) per second (GB/s) and 720K random read IOPS, achieving approximately 20% performance improvement over the previous generation KIOXIA PM6 Series. The new Kioxia drives are available in capacities up to 30.72terabytes (TB), making them the industry’s highest capacity[2] 2.5-inch [3] SAS SSD.

Additional features include:
Dual-port to support redundancy for storage systems that require high reliability.
Flash Die Failure Protection – a Kioxia feature that allows for transparent disabling of a failing flash chip, while maintaining full reliability at the SSD level.
Endurances for a wide range of workloads; read-intensive (1DWPD) and mixed-use (3DWPD).
Security options available[1]; sanitize instant erase (SIE), TCG Enterprise self-encrypting drive (SED) and SED with an additional security option that utilizes a security module validated by the FIPS 140-2 Cryptographic Module Validation Program. FIPS 140-3 validation for the security module is also in process and is expected to be completed in 2022.
