This new 40TB hard drive from Seagate is just the beginning—50TB is coming fast!

I deal with large data chunks and 40TB drives are an interesting idea.... until you consider one failing
raids and arrays for these large data sets still makes more sense then all the eggs in smaller baskets
I guess the idea is you'd still do that, but have more data in each array. It does raise the risk of losing a lot of data, but that can be mitigated by sensible RAID design and backups. And then you save power for the same amount of storage.

I’ll finally have enough space for my meme screenshots.
Or the 8k photos of vacation dinners.

You'd still put the 40TB drives in a raid? But eventually you'll be limited by the number of bays, so larger size is better.
They're also ignoring how many times this conversation has been had...
We never stopped raid at any other increase in drive density, there's no reason to pick this as the time to stop.

I still wonder, what's stopping vendors from producing "chonk store" devices. Slow, but reliable bulk storage SSDs.
Just in terms of physical space, you could easily fit 200 micro SD cards in a 2.5" drive, have everything replicated five times and end up with a reasonably reliable device (extremely simplified, I know).
I just want something for luke-warm storage that didn't require a datacenter and/or 500W continuous power draw.
Cost. The speed of flash storage is an inherent quality and not something manufacturers are selecting for typically. I assure you if they knew how to make some sort of Super MLC they absolutely would.

So all the other hard drives will be cheaper now, right? Right?

Don’t look at Backblaze drive reports then
I have.
But after personally having suffered 4 complete disk failures of WD drives in less then 3 years, it's really more like a "fool me once" situation.
wrote on last edited by [email protected]It used to be pertinent to check the color of WD drives. I can't remember all of them but of the top of my head I remember Blue dying the most. They used to have black, red and maybe a green model, now they have purple and gold as well. Each was designated for certain purposes / reliability.

I bought my first HDD second hand. It was advertised as 40MB. But it was 120MB. How happy was young me?

Gold is the enterprise ones. Black is enthusiast, blue is desktop, red is NAS, purple is NVR, green is external. Green you almost certainly don't want (they do their own power management), red is likely to be SMR. But otherwise they're not too different. If you saw a lot of blues failing, it's probably because the systems you supported used blue almost exclusively.

Of course, because you don't want to lose the data if one of the drives dies. And backing up that much data is painful.

It's not inherent in terms of "more store=more fast".
You could absolutely take older, more established production nodes to produce higher quality, longer lasting flash storage. The limitation hardly ever is space, but heat. So putting that kind of flash storage, with intentionally slowed down controllers, into regular 2.5 or even 3.5" form factors should be possible.
Cost could be an issue because the market isn't seen as very large.

Raid 5 is becoming less viable due to the increasing rebuild times, necessitating raid 1 instead. But new drives have better iops too so maybe not as severe as predicted.

they make bulk storage ssds with QLC for enterprise use.
The reason why they're not used for consumer use cases yet is because raw nand chips are still more expensive than hard drives. People dont want to pay $3k for a 50tb SSD if they can buy a $500 50tb hdd and they don't need the speed.
For what it's worth, 8tb TLC pcie3 U.2 SSDs are only $400 used on ebay these days which is a pretty good option if you're trying to move away from noisy slow hdds. 4 of those in raid 5 plus a diy nas would get you 24tb of formatted super fast nextcloud/immich storage for ~$2k.

I thought green was "eco." At least the higher-end external ones tend to be red drives, which is famously why people shuck them to use internally because they're often cheaper than just buying a red bare drive directly, for some reason.

The main issue I see is that the gulf between capacity and transfer speed is now so vast with mechanical drives that restoring the array after drive failure and replacement is unreasonably long. I feel like you'd need at least two parity drives, not just one, because letting the array be in a degraded state for multiple days while waiting for the data to finish copying back over would be an unacceptable risk.

You might be right. Although I think it's been pretty hit or miss with which drives they use in those enclosures.

This is good to know. I might need to upgrade the storage for my Monero node.

Just wondering, why do you run a monero node?
