News Micron Unveils 7500-Series SSDs: 232-Layer 3D TLC NAND for Datacenters

[Admin]

Micron equips proven 7450-series platform with 232-layer 3D TLC memory to cut costs and boost performance.

This series seems like it doesn’t have any stand-out features with its capacity topping out at a mere 16 TB. But looking at the technical specifications, it’s got something few SSDs have (from all the spec sheets I’ve seen): a 10^18 UBER.

(The highest I’ve seen is 10^27 from Greenliant, and typically 10^17 for enterprise drives.)

Which of the competitor products in this segment uses QLC??
Only solidigm does and they're using it for capacity segment just like Micron?
Except their QLC SSD is DOUBLE the capacity!

The ION 6500 series also uses 232-layer TLC NAND. I wonder what’s going on in the 7500 series that’s capping the capacity to a mere 16 TB in 2023.

Solidigm’s certainly didn’t get to 64 TB-class QLC SSDs by solely relying on QLC’s 33% greater density. Heck, that drives only uses 192-layer NAND.

I suspect like it might be because they optimized the layout to use far less nand flash to reduce engineering costs, therefore it caps out at a lower capacity

After all, kioxia managed 30.72TB with 96L flash and Micron somehow always managed to boast about industry leading
And the difference really is the Kioxia made a very intricate multi PCB design

Now that I look at the article’s main image, it would appear that of the 15 mm thickness, half of it is probably just the heat sink. That leaves 7 mm (a standard SATA drive thickness) for the actual PCB with the controller and memory chips.

It's seems like more of a system vendor, but I found this:

Pure Storage Adds 75TB Flash Module, FlashArray//E and New FlashArray //X //C R4 Nodes

At Accelerate 2023 Pure Storage has launched many hardware innovations including new 75TB DFMs, new Pure FlashArray systems and more.
