Exiting times are ahead for anyone with technology for better non-volatiles or better scaling volatile memory
I am also unclear on how much of a concern leakage is on a SSD. If I leave it disconnected on a shelf for a year, will it have lost data? I have seen some reports that SSDs need to be refreshed regularly, which makes then ill suited for cold storage (eg leave an offsite backup at parents).
They supposedly come with a 2 year warranty but like the GP I haven't had any break (out of six) so I haven't tried using it.
I take an annual backup and ship it offsite. Current wisdom says that the SSD is more perilous to recover than the HDD if I need to restore it within the next year or two.
Hell, I just took my very first SSD (60 GB OCZ Vertex 2) and booted the old install fine after it had sat on a shelf for ~7 years. Of course that just had the Windows boot files on NTFS so I can't say for sure no bitrot had occurred. In the same bin/nostalgia period I had an old 2 GB USB 2.0 flash drive with Ubuntu 9.10 on it that did validate the fs image fine from the same bin as well.
I remember https://www.youtube.com/watch?v=igJK5YDb73w this guy was doing some intentional tests with modern cheapo drives but it hasn't even reached time for the year 2 check quite yet.

I don't think these are meant for ordinary users. One extended vacation and your data is toast...
I see the Micron drives on CDW for the prices you state though:
https://www.cdw.com/product/micron-6500-ion-ssd-enterprise-3...
BackBlaze's site is blocked at work, but aren't they up to using 22TB drives? And I think Seagate announced 30TB spinning drives this year. So that's 1.3PB or 1.8PB with 3.5" drives.
Now if you double the amount of drives (assuming those new Samsung drives are 2.5", and use the propsoed 122TB drives, and you could cool and power it) you'd have 14.4PB!
Amazing since the original design needed like 15 pods for a single petabyte.
R2 is probably a different matter, I guess they probably have a caching layer for that.
BlackBlaze storage pod are 4U, that is 0.9PB / 1U. We have been able to store 1PB per U since ~2020 with EDSFF. So the density achievement isn't quite new.
- 4TB SATA (2.5") SSD: Silicon Power Ace A55, 230 EUR
- 4TB NVME (M.2) SSD: Crucial P3, 260 EUR
- 4TB SATA HDD: Seagate Barracuda, 108 EUR
so HDDs are still more affordable for larger storage, assuming that you're okay with the shortcomings. I think that the differences remain similar at the higher storage capacities too.Admittedly there's only 1 entry for that price, could be a dodgy vendor, but there's plenty of 8TB ones for <$100. Also there's a 16TB drive for $130.

The 12TB listing shows up to me as "Currently unavailable", whereas others show up as more expensive, so instead of 66 USD for a 4 TB HDD I instead get 172 EUR on amazon.co.uk (Seagate Enterprise ST4000NM0035). The prices in the post above were from an e-commerce store in my country, so those are also different from Amazon's in some ways.
Ie that's totally not representing the current prices.
Both official Seagate and WD sites still state ~$100 for the regular (not NAS/Gold/Exos/whatever) 8Tb drives.
It's still x2 for SSD per Gb and it would be for some time, but you always trade the capacity for the performance.
SATA 6gbit is barely enough for 8tb.
So you can have M.2 SATA (not NVMe) or M.2 PCIe (NVMe) drives, both in the bubblegum form factor. The drive from the article uses U.2 connector, which also provides SATA and PCIe (some desktop boards did come with such a connector, parallel with M.2 slot).
First you need a u2 card (or whare er new standards there are)that works and then you need actual u2 drives which are friggin expensive.
With storage density reaching tens of terabytes per drive, sata 6gbit is not enough.
