Seems it's not uncommon around here for people to have big media servers. I'm always looking to make my own media server physically smaller, use less power, and/or more reliable.
It seems to me, media storage (music, movie, picture collections) is ideally suited to WORM devices (write-once, read many). As far as I can tell, there's no true high-capacity WORM media available, at least not at SOHO prices. I like the looks of mdisc, but I'm holding out for a 100x increase in capacity.
Ignoring cost for a second, what about using SSD as WORM drives? In other words, you fill one up, then mount it read-only. What's the expectation for long-term data integrity on an SSD in this scenario? You can do the same with a traditional spinning platter drive, but it's still spinning, consuming power, subject to vibration risk, a head crash, "click of death" after a power cycle, bit rot, etc. SSD at least removes all the mechanical points of failure.
But I realize the NAND memory within an SSD isn't perfect. Have any studies been done that investigate the long-term data integrity of NAND memory? What are the chances of bit rot?
Seeing the review of the Icy Dock 6-in-1 cage made me dream of building a tiny, super low power, silent storage server. Imagine two of those cages in something like the Supermicro SC731 mini-tower and a dozen 1 TB SSDs. Nearly 12 TB of silent, super-fast storage. You could throw in a couple spinning disks (that usually stay powered down) and have some redundancy with snapraid. Or I suppose if you can afford all those SSDs, might as well throw three 4 TB drives in there and have it 100% duplicated.
