I checked the specs here: https://www.micron.com/content/dam/micron/global/public/prod...

The interface looks equiv to 4x PCIe 5.0.

    > Sequential write (MB/s): 2,700
That is pretty awful write performance. Does anyone know more about this? I assume all of these hyperdense SSDs suffer from the same drawback. Also, I heard that the E3.L interface can support up to 16x lanes, but there are no practical commerical products at this point.

I look forward to have my favourite hyperscaler grant me 1000 "premium" IOPS per VM on this monster.

IOPS? This thing has slower IOPS than an old SATA SSD (~40k / QLC). I think it is meant for sequential operations only.

Note how that is still well in excess of what e.g. AWS EBS GP3 volumes offer (or at least used to, though even now their "80K IOPS" is measured with 64 KiB random transfers, whereas Micron measured that 42K IOPS with 4 KiB random transfers), which is what the person above is gesturing towards.

The same EBS GP3 used to be specified with 16K max IOPS at 16 KiB random transfers until pretty recently.

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?

Probably for a similar reason why I would rather buy a single 4TB SSD than fourty 100MB SSDs.

It’s about density in a datacenter. With this you have 1PB in 4 drives, fitting in a 1u rack, which is just incredible. Also these drives don’t use regular SATA or SAS, they use PCIe, so these drives are also quite fast in comparison. Density has a power efficiency aspect as well both in just having fewer drives and requiring fewer servers to put drives into.

A 42U rack filled with 1u servers with 8 drives each, will have 84PB of data. It feels like it was a few month ago where you could buy a rack with 1PB of storage, and that was awesome. Not anymore.

Earlier quoted context omitted.

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…

It's not just a single PCB, but a sandwich of several.
