I get these emails and comments all the time - "I want a larger capacity SSD". Ok, here ya go:

Samsung's earlier 48-layer VNAND announcement was exciting, but we already knew about it going into the keynote. What we did not know was that Samsung was going to blew the doors off of their keynote when they dropped this little gem. It's not just the largest capacity SSD, as this thing is more dense than any HDD's available today as well. That's 16TB of 48-layer TLC VNAND packed into a 2.5" form factor SAS-connected SSD. what do you do once you have such a high density device? Well, you figure out how many you can cram into a 2U chassis of course!

Yup, that's 48 of those new SSDs, making for a capacity of 768TB in a 2U chassis. Samsung described this as a "JBOF" (Just a Bunch Of Flash), so processing the 2 million IOPS this array is capable of will have to be left to the connected system.

No word on pricing, but I'd think we are in 'mortgage the house' territory if you want to put this into your home PC.

There is more to follow from Flash Memory Summit, but for now I've got to run to another meeting!

Seagate? WD? Can you hear that? It's the sound of an era fading away into the history books. I hope gouging us all for the past 5 years was worth it. That's about all you're going to get out of the market.

And then Intel/Micron comes along with Crossbar, and the NAND pusher's past 5 years of doing the same thing are History! What's good for the goose...

P.S. Spinning Rust is not going away, just like Tape it's still good for backup and can last for a good long while in the powered down state.

Yeah, HDDs are going to beat flash in cost/GB for a good long while.

Spinning rust is only cheaper per GB if you only look at CAPEX.
If you have to pay for the energy, then they are far more expensive / GB than flash.

I wish 16TB AHCI/SATA SSD is cheaper.

I hope it's NVMe...

I find it so surprising that hard drive manufacturers (Seagate, Western Digital, Toshiba, Hitachi) haven't attempted to enter the SSD market space at all. They haven't even attempted purchasing a smaller SSD company like OCZ to rebrand and generate a new revenue stream. What are these hard drive companies thinking by completely ignoring this new technology? Their stocks will fall to zero eventually...

I think Seagate is producing SSDs. They own SandForce now.

OCZ is owned by Toshiba.

How do they expect to keep those 48 layers from overheating?

August 13, 2015 | 04:03 PM - Posted by Allyn Malventano

The chip is still relatively thin compated to the heat being produced. It is actually minimal enough that Samsung can stack flash dies 16 high to a package and still not have an issue with heat.
