Samsung Ships 15.38TB SSD With Up To 1,200MBps Performance (computerworld.com)

Lucas123 writes: Samsung announced it is now shipping the world's highest capacity 2.5-in SSD, the 15.38TB PM1633a. The new SSD uses a 12Gbps SAS interface and is being marketed for use in enterprise-class storage systems where IT managers can fit twice as many of the drives in a standard 19-inch, 2U rack compared to an equivalent 3.5-inch drive. The PM1633a sports random read/write speeds of up to 200,000 and 32,000 IOPS, respectively. It delivers sequential read/write speeds of up to 1,200MBps, the company said. The SSD can sustain one full drive write (15.38TB) per day, every day over its life, which Samsung claims is two to ten times more data than typical SATA SSDs based on planar MLC and TLC NAND flash technologies. The SSD is based on Samsung's 48-layer V-NAND (3D NAND) technology, which also uses 3-bit MLC flash. Also at Hot Hardware

We're all guilty of having overpowered machines from time to time (because when we need that horsepower, there's no alternative to having it local). In a somewhat related subject, I've got triple monitors that have beautiful color... I assume. They've all got green on transparent consoles on them at about 120 columns wide. It's enough to make a graphic designer cry.

That being said, my laptop is a special order ThinkPad (i7 w/ 8 threads@~3.2GHz, maxed out RAM, 1/2 TB SSD, etc) - I think I get maybe 90 minutes on a 12 cell extended battery and I have docking stations at home and work because all that power means it ain't really portable for most definitions of "portable" (or at least for very long). Also makes a great heater during the Minnesota winter. There's nothing wrong with wanting a powerful machine, so long as you accept the trade offs you're making to have that power.

You're right, they just have a higher quality of life, and illegal immigration is actually quite low due to a lack of opportunity here.

Might want to update your ideas on where the majority of the world is compared to us. We spend significant digits more on healthcare than any other country and we're pretty much the only industrialized country to not to have single payer. Your arguments are tired. Bernie's ideas only seem crazy if you consider it all happening overnight instead of saying this is the direction we should head because it will help a lot of people that have been receiving less and less help. Childhood hunger was largely a solved issues by the end of the 70s. Why do you think it came back in the 90s and is rampant again? What are our tax rates today compared to where they were then? Oh yeah, a LOT lower.

Re:How much is it at Newegg?

[mattack2]

How can you say it is low when there are 11 million already here illegally..

lack of opportunity? As I said, why do people KEEP coming here if there's no opportunity?

Yes, we should have "single payer". The payer being the one getting the healthcare.. Not me paying for your health care, not you paying for my health care.. at least not *mandated*. Yes, things like insurance are averaging out costs between many people.. But even car insurance is not mandatory as people think. One can use a bond as proof of having the money to pay, instead of insurance.

They leave countries where they had worse conditions, that's why they come. They immigrate legally when they have opportunities...

For this performance and density, the $6000 mentioned by the AC above (a fictitious number I'm assuming, since I can't find any references to an actual price) would be pretty good, if it were true. That's under $400/TB. Consumer-grade drives were at that price/TB not too long ago, for much worse performance and density.

Re:LoC

The units in TFS are messed up. So it's 15.38TB... Assuming the stupid new IEC decimal units, not real 2^40 terabytes. But then performance is measured in MBps, or megabytes per second. TFA compares 1,200 with the typical figure of 550 MBps for consumer SSDs, but that's 2^20 byte megabytes measured by benchmarking software. Who knows if Samsung uses the same units, or is trying to screw up with decimal megabytes.

Which is why you use those "stupid units" so you don't confuse TB/TiB and MB/MiB. Though I just assume it's all decimal because it's not only easier, it makes numbers look bigger and thus, people use it over base-2. Since it's storage, it's almost always in decimal, at that.

Still, 1.2GB/sec is not that impressive - I think even a reasonably priced MacBook already gets that speed off its PCIe SSD, if not higher (1.2-1.7GB/sec). Granted, they're only up to 1/2 TB now in size, so this thing's roughly 30 times bigger, but still.

SATA3 gets 540MB/sec typically fully loaded, so this SSD using SAS is getting a little over twice that. It's why consumer SSDs have started migrating to PCIe.

Re:LoC

[Coren22]

With SSDs, it is possible it is not the decimal units, around half the drives are base 2 sizes from what i have found. I however am not sure how you would arrive at 15.38TB. If I assume is is 16 TIB I get 17.59 TB or 16 TB comes out as 14.55 TiB, so I am not sure where 15.38 TB comes from at all. Perhaps there is some kind of loss to the slack used for reassigning bad bits though.

Re:LoC

[slashping]

I for one would rather calculate with factors of 1000 than 1024. The only place where the binary units made sense was in parallel addressable memory where you have a bunch of N address wires making 2^N possible combinations. For speeds and other forms of storage, the decimal units make a lot more sense.

Re:LoC

[xaxa]

All SSDs have plenty of spare blocks, so the final size is a decision on how many spare blocks to allocate. Measuring in a power of 1024 makes little more sense than for a hard drive.

For one example, my SSD is 256GB:

Disk /dev/sdg: 238.5 GiB, 256060514304 bytes

Huge advances

[Anonymous Coward]

People say that HDDs are killer on enterprise due to large data density. However, with products from Fixstars and Samsung it seems that SSD data density has quickly taken huge leaps. I can buy 8 TB HDD in 3.5" form factor. However, this Samsung SSD already packs 15 TB in 2.5". Meanwhile, HAMR is still in the skunkworks. As the prices will eventually fall as well, I see SSD technology simply taking over the mass storage market in few years. Any counterarguments?

Re:Huge advances

[NatasRevol]

Not a counter argument, but VSAN will/should put most raid arrays out of business too.

Re:Huge advances

[Archangel Michael]

VSAN has proven unreliable in our environment, with no real answers from VMWare. We have pulled it from production do to machines just dropping offline when a disk has timing issues.

Yes, we used nothing but VMWare approved hardware and run in a sanitized environment. They can't explain what is wrong, and haven't been able to fix the issue. Unstable environments aren't "Enterprise" ready.

VSAN looked promising, and the promises were such that we bought it. The reality is that it isn't ready IMHO. We wish we could get our money back. Yeah, it is that bad.

Re:Huge advances

[NatasRevol]

And I've heard many more people having success with it.

In fact, googling for vsan failure turns up very few accounts, even in the vmware forums where people complain about everything.

I haven't tested it out myself yet - hardware costs real money - but most VMware sysadmins see the real benefits to it & are testing the waters.

Re:Huge advances

[Archangel Michael]

I'm just telling you our experience. Support from VMWare hasn't been able to resolve our issue (and they have tried).

Re:Huge advances

[castionsosa]

vSANs are going to be more popular once Windows Server 2016 hits the server rooms, because of Storage Spaces Direct. Of course, it would be nice if one could interconnect machines via Infiniband like Isilon nodes do, but even though the technology is somewhat shaky as of now, the buzzword of hyperconvergence is out there, and there may be use cases for it, where one can just add more compute nodes and gain more disk space to the backing store.

Will it replace a SAN? Not really. In fact, it seems like enterprises are moving to stuff like Tintri and PureStorage, because those tend to be better for the specialized purposes of having the I/O needed for virtualization. vSANs do have their place, but it will be hard to convince people to stop using their tried and true fiber channel fabric, especially for production critical tasks. Eventually, just like virtualization and SANs, it will wind up in production server farms, but vSAN stuff will have to earn its bones first, just like any new technology.

From what I have seen, they are all front loaded. Would it not be better to have them top loaded? e.g. have a drawer that you pull out and then have the SSDs mounted vertically with the contact at the bottom.
I would imagine you could place a lot more in them as they can be closer together as the full depth could be used. Could be that it has to be 3 units instead of a 2 unit.
So just a print plate the depth of the rack with a lot of SSD connectors on them. Plug them all in and you are done. Obvious some space needs to be reserved for some other parts.

Any reason why this has not been done?

Re:2.5 hdd in 19" racks aren't new...

Compellent make a top-loading enclosure like this.

I think the reason they're loss common is that this kind of storage density has been pretty uncommon until relatively recently. Drive sizes have grown fast enough that the same 12 or 24 drive front loading shelf met a lot of needs over time.

The power consumption of a rack with a couple of 80 HDD drawers would be pretty intense, too.

Re:2.5 hdd in 19" racks aren't new...

They say it fits "a 2.5 inch form factor", not "the 2.5 inch form factor". Looking at the picture, it certainly looks like the drive is 'taller' than a normal 11mm or so SSD designed for laptops, taking up a larger volume than normal. Not sure what "the" 2.5 inch form factor allows. While probably not taking up half the volume of a 3.5 inch drive, it may be close enough to not allow more than 2 in the same space, especially given the need for connectivity to the drive for power and data.

Real consequences

[info6568]

I have been working on enterprise-grade applications running on Raspberry-Pi type of computers. In this case, less is more (less trashing resources produce better usage). And it is possible to execute transactional monitors with a mere 6 megabyte of RAM, so the overall 1 gigabyte of memory on those machines is good enough for complex tasks when it is wisely used.

And now we have more than 15 terabyte SSDs that it is like to lost a needle not on a haystack but on the milky way.

Of course, it is possible to use that space on gaming or raw video storage, even on hungry relational database storage, but what could be done when working with care? There are applications only the imagination can figure about this type of fast, power saving and huge storage. And there are other consequences also: better and cheaper low level SSDs ( ) for general usage, that could really break the hard-disk kingdom.

For some applications the larger, slower SSD's may be fine, but for database applications those random write spec's are pretty lacklustre.
