Samsung on Thursday introduced its new lineup of high-capacity SSDs for enterprises. The new Samsung PM1633a family of drives includes the world’s first SSD that can store 15.36 TB of data and which leaves behind even the leading-edge hard drives. The solid-state drive not only offers the world’s highest-capacity, but also boasts with increased reliability and high performance. The manufacturer is already shipping the new SSDs to select customers.

The Samsung PM1633a 15.36 TB SSD can deliver up to 1200 MB/s sequential read performance and features random read and write speeds of up to 200,000 and 32,000 IOPS respectively, according to the manufacturer. The 15.36 TB SSD supports 1 DWPD (drive writes per day) throughout the period of several years (unfortunately, Samsung does not specify of how many), which indicates very high endurance. The new solid-state storage solution features SAS-12 Gb/s interface and is compatible with servers that support drives in 2.5”/15 mm form-factor. Samsung does not reveal power consumption of the PM1633a 15.36 TB SSD, but based on power requirements the SSD can consume up to 13.7W.

Samsung PM1633a SSD Specifications
  15.36 TB
Controller Samsung proprietary controller
NAND Samsung's 256 Gb 48-layer TLC NAND
Sequential Read 1200 MB/s
Endurance 1 DWPD (Drive Writes Per Day)
Interface and Form-Factor 2.5"/15mm SAS-12 Gbps

The PM1633a drives are based on Samsung’s new proprietary controller that can concurrently access large amounts of high-density NAND flash with the help of a special firmware. Thanks to the new controller, the PM1633a SSDs are even faster than the PM1633 drives unveiled last August (sequential read and write speeds of up to 1100MB/s and 1000MB/s, up to 160/18 thousand random read/write IOPS). Typically, high-capacity SSDs do not offer truly high performance because of peculiarities of their internal architecture, but Samsung has managed to develop a controller that weds performance and capacity.

The Samsung PM1633a SSDs utilize the company’s third-generation 256 Gb TLC 3D V-NAND memory chips. The 256 Gb dies are stacked in 16 layers and form a single 512 GB package. Samsung uses 32 of such packages to build its most spacious SSD, leaving around 1 TB of NAND for overprovisioning. The giant drive also features 16 GB of DRAM cache to ensure smooth performance. The Samsung PM1633a 15.36 TB will be the second product to use the company's 48-layer TLC 3D V-NAND after the Portable SSD T3. Eventually, Samsung will further expand usage of this flash memory.

The advantages of 15.36 TB SSDs in the server space are hard to overestimate. There are 2U servers that can fit in 48 SAS3/12G storage devices (1, 2). Each of such machines can store 737.28 TB of data (if fully populated with Samsung’s new PM1633a SSDs), whereas a 42U cabinet featuring 21 of such servers will be able to store 15482 TB of data (15.4 PB). By contrast, storage capacity of a standard 42U storage rack based on 360 3.5” 10TB HDDs is around 3600 TB.

Samsung did not reveal the price of its 15.36 TB SSD, but is probably in the range of several thousands of dollars.

Later this year Samsung plans to add drives with 7.68 TB, 3.84 TB, 1.92 TB, 960 GB and 480 GB into its PM1633a lineup.

    Personally I would take out the delivery driver, far simpler and the kit isn't second hand.

    You posess most of the basic knowledge necessary to plan the heist of your old place then. First step of casing a target would be finding out who works there. If the keycard and any actual keys are on the same person and that gets you all the way to the target area, you're a roll of duct tape away from bypassing most security (especially if it's an employee with access outside business hours). CCTV is not a problem, a burglar would assume it's there. As in anything, knowledge is key.

    Pfft, I was dismissed in a manner that is best described as legally dubious *at best* and morally, utterly repugnant. I have no interest in giving them any kind of attention, theft or not.

    Handily, people who work there now realise that the management are shonky as hell (many other people have been 'disappeared' too) and most of their staff are currently looking at their options now that they are aware of just how tenuous their positions are thanks to the management having no idea how employment law works and not being afraid to exploit it aggressively.

    They'll go down due to inability to hire talent - as the people who have left recently have large social media followings, locally - *long* before they need to worry about thefts.

    I won't pretend that doesn't please me.

    This applies to basically any corporation. You can always kidnap an executive and get him/her to spill out some valuable company secrets. The question is are you willing to risk life in prison for something that's very, very difficult to sell. That's right, you can't just sell 15TB SSDs on Craigslist. The companies buying these drives are fairly limited in number, and they most certainly won't buy them from a trunk of a truck.

    Besides, this drive isn't even that expensive compared to many other items data centers house (CPUs, network switches etc).

    A high end security consultant asked me what the best way to break into a corporate network was, many years ago. I suggested war-driving, botnets, port scanning, etc. Nope.

    Grab the security guard who is paid minimum wage, and break each of his fingers till he gives up his access, then launch an attack from *inside* the network based on his privileges.

    Your hardware can be impenetrable. Wetware rarely is.

    Ours was similar.

    Badge into gate to access parking lot. Walk into building and badge to open tube. Once inside glass tube use hand scanner to get it to open the other side. The whole time security is looking at you making sure your face matches the picture they have on file that pops up when you badged in. Now we are in the office area. To get to a colo you have to badge and hand scan once more. Federal government servers? Those are locked inside a cage inside that room which requires one more badge entry. Stealing drives? Sure I could. I'd also be caught soon after and tossed in jail. All my security clearances revoked and never work in the industry again. also doubt I could sell these at the local flea market for anything close to their worth so whats the damn point? Even if the drive is $5,000 retail their limited usage scenarios would make them damn near useless unless you know someone selling to a government that shouldn't have them.

    That is true, and expensive storage solutions are not new to the datacenter storage world. There was a time when SCSI drives were in this price range.
  • FunBunny2 - Friday, March 4, 2016 - link

    "There was a time when SCSI drives were in this price range."

    well, "While it’s hard to put an exact price on a single drive, it would’ve cost somewhere in the region of $50,000 to $100,000 in 1989 — or about twice that, in today’s money. That’s around $50,000 per gigabyte — or one million times more expensive than today’s hard disk drives, which are currently priced at around five cents per gig."


    for nearly 2 decades, even IBM uses "commodity" 3.5 drives in their mainframes.

    Seriously. When I was in HS I did a pilot program where they were (attempting) to teach the CCNA to juniors/seniors in high schools. During said program, I had the opportunity to visit the datacenter for one of Oracle's main sites. Needless to say, security was top notch (considering they had over 100 million dollars of equipment in there, kind of "to be expected").

    IMO the coolest thing was the fire suppression system. Basically if a fire was detected, it would sound a klaxon, you had something like 10 or 15 seconds to exit the room, otherwise you were trapped inside, and it would suck all the oxygen out and replace it with some sort of inert gas (argon maybe?).

    The second coolest thing was the backup generators. Basically it was 2x Chevy 350 V8's that could be fired up in a power outage to power the entire building indefinitely (provided they had enough fuel of course).

    1U with 48 bays? impressive. 200k+ server unsecured? equally impressive
