Are SSHDs any good? MSY has Seagate 8TB SSHDs for only $309. That's cheaper than a 6TB disk using regular technology, suspiciously cheap. I'm guessing that they use something like Shingled recording to improve the storage:price ratio and use the SSHD caching to allow decent performance without the OS optimising write patterns for it.
SSHD's are fine, but what you've linked to is an Archive / SMR drive which is totally different, and isn't an SSHD. SSHD = classic HDD with some SSD caching SMR/Archive is something to avoid unless you're going to use the drives like tape given the ~200MB block size for writes.
