Last but certainly not least are preliminary specs for the He12, which boast particularly impressive low QD random write performance and a notable bump in Watts/TB despite the addition of an eighth platter to achieve the 12TB capacity. Note that this is not an archive class product and is meant for continuous random access.

Not bad HDD progress considering we were just discussing 10TB SMR this time last year. We'll be confirming the performance of these as samples arrive for testing.

Press blast appears after the break.

Good lord, time to start saving up again, those 12TB drives look tasty.

December 6, 2016 | 01:10 PM - Posted by Master Chen (not verified)

12TB on an HDD? Isn't that just physically impossible EVEN with HAMR (unless you're going 10+ plates and hence thicker/bigger form-factor than 3.5", of course)? If my memory is right, standard (HAMRless) platter's maximum physical capacity is 750~something GB, and HAMR allows to expand that to 950~1250GB per one platter tops. No way in hell you can fit something like that into a standard 3.5" format for an HDD if you're going beyond 8TB in it's capacity.

I like lots of platters as then the read/write heads can store more info without having to step. I’d like there to be that OS option to keep files stored on a single cylinder, or adjacent cylinders so the more platters the larger the storage space in the cylinder!

Hell have 8 platters(16 surfaces) for data and 2 platters(4 surfaces) to store the CRC/ECC bits for some interesting cylinder mode data/file allocation with error correction!

December 7, 2016 | 08:47 PM - Posted by Allyn Malventano

These will fit 12TB in a standard 3.5" form factor drive, using no HAMR and no SMR. Standard PMR. It may be Advanced Format (4KB ECC), but that's fairly common these days. They are adding an 8th platter though, so the bump in per-platter capacity is not as severe as with the last jump. The helium (or effects of switching to helium) does help increase per-platter density. That math does work out to 1.5TB per platter, or 750GB per single platter side.

December 8, 2016 | 12:45 AM - Posted by digiboy (not verified)

I'd say if helium does help increase per-platter density, then it is simply a race for HDD manufacturers to add more platters. The next step would be to make platter thinner so that a single HDD can have 20 platters! If its already at minimum thickness, then they need to invent a new material combo. There's still hope for mechanical drives!

Wait, WHAT?
Are you saying they're writing to BOTH sides of the platter now? That feels kinda nasty, to be honest. There's got to be a crapton of heads in there, to do something like that. That can't be good in a long-term scenario, IMHO.

Nice to finally see an 8 lane PCI-E drive being utilized! Interesting product.. Wonder how many packages/dies are on the SN260 to get that 6.2gb/s though.

Thanks for the great in depth article as always Allyn!

January 6, 2017 | 05:06 PM - Posted by pyite (not verified)

The SN260 is x4. I can easily get 6 GB/sec on reads with both the 3.2T and 6.4T sizes. This thing is a monster.

It's tough to say how many nand chips are on there with the heatsinks and stickers, but it looks like maybe 24 (12 per side).

January 6, 2017 | 05:13 PM - Posted by pyite (not verified)

I lied, it really is x8.

I have just, 2 days ago actually, was able to order a 250GB Samsung 960 EVO M.2. I think it will take around 2-3 years for consumers to get their hands on one of these. They should be less than 5 cent a gigabyte. But good to see the death of hard drives nonetheless. They should almost be history by 2020. Let's see.

How long helium will be kept inside?
As soon it leaks out the drive overheats and dies?

December 6, 2016 | 10:50 PM - Posted by remc86007

I believe they are completely sealed.

December 7, 2016 | 03:09 AM - Posted by Anonymous (not verified)

Helium will slowly permeate through the cover seal, won't it?

December 7, 2016 | 06:51 AM - Posted by Anonymous (not verified)

The Helium is completely sealed inside the drive, 2.5M hours MTBF!

Check this link for the details on the technology used for sealing Helium in the drive:

Thanks. Still hard for me to believe that HDD is 10 times as reliable as heatpipe.

Excellent. More space for porn.

...

What?!

December 8, 2016 | 12:51 AM - Posted by aporntice (not verified)

Interesting. How do you keep them? With RAID or separate backups? Do you neatly file them? How do you categorize? Do you use some software to help with searching? Do you keep or replace if there is a higher resolution?
