Samsung Introduces World's Highest Capacity Enterprise SSD - 15.36 TB

[Ja.KooLit]

remarkable!!!!! samsung does push limits and set standards.in few years time, this will be on consumer level price.

on a side note, very odd capacity. 15.36tb?

 

[Patriot]

should note this is enterprise 2.5" spec and will not fit in laptops or anything like the nuc that uses the laptop 2.5" bays.

All of the high capacity enterprise drives are multi pcb... Truly awesome to take apart...
But they are also tanks and super thick.

Here is a PX03 Toshiba 1.6TB

And a 1200.2 Seagate. 3.2TB

 

[Mussels]

This got me moist. Sure its not consumer level, but how long before a 32TB variant surfances? 64TB?


SSD's are finally hitting the point they can completley surpass mechanical drives in capacity and reliability, only price is left.

so what will happen with our neighbours who offer his "helium" storage lol ???

Why odd? This thing has probably a full 16TB flash, where (due to overprovisioning) only 15.36TB are usable.
Never wondered why there are all these 480GB SSDs when they should've 512GB?

I actually wondered that this drive does come with only 4% overprovisioning. For an enterprise SSD something around 13% is typical.

google had that report recently that enterprise SLC SSD's were no more reliable than consumer MLC in the end, so i think they're settling on finalised numbers as the tech matures.

The debate about SLC vs. MLC has nothing to do with this drive, 'cause it already uses MLC V-NAND and if there is a difference in overprovisioning needed between SLC and MLC, then it is SLC which probably need a little less for the same lifespan (TBW or DWPD over a certain amount of time).

The first SSDs I bought back in the days were SandForce 1500 drives which used 27% in overprovisioning.
The wear-leveling must've been evolved al lot since then.

 

[Mussels]

my point was about how the overprovisioning is shrinking over time, and seems unrelated to reliability.

 

[Breit]

I'm not sure what that Google report really means. I've not read it, but I'm guessing the results are just an observation of failure rates for certain drives. I'm further guessing that the SLC drives they were using are probably older tech than the MLC ones in the report due to slower developement cycles for enterprise-class hardware. But most importantly: The drives from the report must have been a few years old to make statements about long term reliability. I'm not sure if this gives an unbiased picture over a still very young tech were major advancements happen on a daily basis.

It's more than mere observation. Google actively studies this, jist lime the extensive report they did a couple years ago on HDD failure rates.

Google has an invested interest in tracking and studying these things, because the massive number of drives they use and replace each year worldwide in their server farms is staggering.

Because it's calculated different. Based on standard HDD capacity, not with standard 2^x. It's the same with that 13TB drive from Fixstars. It's much bigger per se, but available space is only 13TB.

But you don't know how they did it they might of cherry picked what the out come was, kinda like voting LOL.

How ever i cannot think of hand why they would fix the results. but still don't they did or didn't, more on topic i would of liked they of shown more pics showing how it was built .

google want the results honest because their findings will push sales up for reliable drives/models (directly via their own purchases, indirectly via encouraging others to buy them), thus encouraging drive manufs to push drive reliability up

 

[cdawall]

And we won't see a large shift to SSDs until SSDs are basically as cheap as HDDs so the major computer manufacturers like Dell and HP start putting SSDs in their large volume inexpensive products.

That already happened, quite a few sub $800 PC's come with a 128/256GB SSD for the OS and a 1/2TB storage drive. Quite a few customers ask for it specifically. The shit has started, 500GB drives are downright affordable right now.

 

[R-T-B]

so what will happen with our neighbours who offer his "helium" storage lol ???

The price will drop.

...How long that can be sustained is anyones guess.

Just like a 2TB drive is actually 1.8TB due to the 1,024 thingy...

Exactly, if you do the math, real vs. spec'd is about 93%, due to 1000^3/1024^3=0.9313...

It even says in the press release that this particular SSD is composed of Samsungs new 256GB (gigabit) VNAND flash chips (512 of them). These chips are then stacked over 16 layers forming packages of 512GiB in size (512 * 2^30 Byte). It further says there are 32 of these package giving a gross amount of 16384GiB of flash. If you substract 1024GiB for overprovisioning from that, you probably get 15360GiB or ~15.36TB.
