They haven't released details but I was able to find a Solidigm D5-P5336 122.88TB drive for around 40,000 USD, as a guideline. So ... more than that.

Okay, so that 122TB drive costs about $330/TB. I haven't bought a hard drive or an SSD in at least a decade (I get stuff for free, basically) but…that seems a bit high, right? Seems like well-rated consumer-level SSDs cost around $250 for 1TB right now. What accounts for the premium price/TB of these extremely high capacity enterprise-targeted drives?

Density, power efficiency, write endurance, sustained write speeds under continuous load, power-loss protection.

Can someone who knows explain what is the benefit of having all that data in one ssd instead of splitting it up into hundreds of individual drives? Does the single ssd benefit is more performance or does it really tuen out to be cheaper than hundreds of individual drives?

DENSITY. Hyperscalers want to store as much data per rack and per data center as possible. They will eventually have hundreds of thousands of these drives.

I fondly remember when i could buy a well-rated consumer-level SSD for a lot less per TB...

I paid $300 each for my last two SSDs, 4 TB Samsung 990 Pros.

They’re currently selling for $942.72 on Amazon.

I was quoted $18K for a 3.7 TB Dell NVMe disk the other day. I'm gonna guess these drives are literally a quarter million each

$200/TB is reasonable. $300 if it is VERY fast. That is just robbery.

The u.2 form factor is slightly larger than a 2.5" drive. I can imagine the entire space in it taken by Flash chips. I can't imagine what cooling scheme do they employ for the chips in the middle.

The U.2 form factor is a 2.5" drive, not larger than it.

"U.2" does not change anything in the mechanical characteristics of a 2.5" drive, it just replaces the SATA or SAS electrical interface with a NVMe electrical interface.

You can mount a U.2 drive in any location intended for 2.5" drives, as long as its height can fit there.

However, 2.5" drives come in various heights. Many laptops and mini-PCs that accept 2.5" drives accept only some of the smaller heights and they do not accept the greater heights, like 15 mm, which are typical for enterprise SSDs and HDDs, regardless whether they have a NVMe, i.e. U.2, or a SAS interface or a SATA interface.

This new high-capacity U.2 SSD has the standard 15 mm height of the 2.5" form factor.

Apparently TDP is 30 watts¹, according to the product brief. I would imagine it's a single PCB with flash chips on both sides then thermally bonded to the aluminum chassis. That should keep all chips at approximately the same temperature. On its own it could be easily air cooled, but with 24 in a 2U chassis you'll be having some decently hefty forced air over the drives. 1. For comparison, an HDD usually comes in aro…

Given the cost of 24 of them, you can probably buy solid silver heatsinks watercooled with tears of sysadmins.

Hey! You leave me out of your twisted fantasy!

I just want....I just want hard drive prices to come back down. *sniffle*

Perhaps their usual buyers just care less about retention? Those drives aren't going to be used for cold storage, and it is basically a guarantee that there will be checksums and some form of redundancy. Who cares whether the data is retained for 10 or for 15 years after writing when you can do a low-priority background scrub of the entire drive once a month, and when there are already mechanisms in place to account…

QLC retention reported to be around 1 year in unpowered state. I would assume, that drive does background refresh, though. No idea what effect it has on total drive lifetime. It is still mean that if you use it for cold storage it has to be powered.

Why is it mean? Why would you want to use a technology that is unsuitable for cold storage for cold storage? You won't even get the power / IOPS benefit if all it does is an infrequent replication of data and is then switched off.
