Two interesting updates based on what's been announced so far in 2019: PCIe 4.0 will be arriving in the consumer market this year, with a new generation of AMD Ryzen CPUs providing host support, and at least one or two consumer-class NVMe SSD controllers supporting PCIe 4.0 should be ready to start shipping in retail products by the end of the year. (The enterprise/datacenter storage market's transition is already we…

solid state NAS not not laughable, just expansive. RAID 10 a few NVME and you can get decent throughput (and storage size) with existing technology.

Exciting times indeed, just type "ssd" in your favorite search box. I'm about to upgrade to a 512GB SSD that costs half what an SSD half its size used to cost 5 years ago! Starting this year, I'm considering getting a low-end 120GB for $25 every year on January 1st to use as a write-once backup for all my work.

edit: i cannot arithmetic today, or sanity check my arithmetic. sorry. sigh.

I'm not sure how you got that $25 = 41 years of 120GB of storage on Backblaze. Their current pricing appears to be $0.005/GB-month... which would be $295.20 for 41 years of 120GB of storage. > i wouldn't trust a cheap SSD to still work in 41 years I wouldn't trust almost any company to still exist in 41 years, including Backblaze. Preserving data over that length of time will probably require active management of the…

> RAID 10 a few NVME and you can get decent throughput (and storage size) with existing technology. is there a good reason to do this in a consumer setup? max realistic throughput over gigabit ethernet is only ~120MB/s, which can easily be saturated by sequential reads or writes to/from a single modern spinning-rust drive.
