Samsung is a dangerous competitor in the SSD space. Not only does it make its own controller, DRAM and NAND, but it also has an incredible track record in terms of reliability. Samsung SSDs were among the first I reviewed and while they weren't anywhere near the fastest back then, every last one of those drives is still working without issue in my lab today. It's also worth pointing out that Samsung SSDs are also one of the two options Apple rebrands and delivers in its Mac lineup. To continue to hold on to Apple's business for this long is an impressive feat on Samsung's part.

In the early days Samsung actually sold reference designs to companies like Corsair and OCZ. Its partners could then rebrand and resell the drives, which they did. Samsung was still learning the market and after being overshadowed by Indilinx in the performance segment, Samsung retreated. Returning last year to the consumer market Samsung had a new strategy in mind: go directly after the channel. Seeing no point in reselling its designs to third parties, Samsung made its SSD 470 available to both OEMs and consumers alike. OEMs were free to obscure the Samsung name but consumers were told upfront what they were getting. Samsung even spent a good amount on packaging for their drive just to develop its brand.

Although the 470 was a downright decent 3Gbps drive, it was competing in a world dominated by 6Gbps alternatives. Crucial's m4, Intel's SSD 510 and OCZ's Vertex 3 all offered better performance, at a similar price point. The only leg Samsung had to stand on was reliability, which believe it or not can sometimes take second place to performance depending on the target market. What Samsung needed was a faster drive that didn't sacrifice reliability and didn't move price points up. That's exactly what the Samsung SSD 830 is designed to do.

As we've already mentioned, the 830 is an evolution of the 470 design. It still employs a page-mapped architecture to deliver high random and sequential performance, but as a result requires quite a bit of on-board memory. Samsung has no qualms about storing user data in DRAM temporarily so it outfits the SSD 830 with a massive 256MB DDR2 cache. While this cache was spread over two chips in the 470, it is contained in a single package in the 830.

On the interface side Samsung gave the 830 a much needed upgrade to 6Gbps SATA. With a higher speed interface to the host controller and some tweaks on the firmware side Samsung is able to deliver much higher performance than the outgoing 470. Samsung manufactures and uses its own 2x-nm Toggle-mode DDR NAND which is fairly similar in performance to the ONFi 2.x NAND used by Intel and Crucial (133Mbps data rates per interface).

Little is known about the 830's controller other than it is a multi-core ARM design. Samsung claims the controller has three cores however we don't have any information on the design of each core nor the type of work each one does. As SandForce has claimed in the past, SSDs are rarely limited by processing power. Instead it's the firmware, algorithms and internal chip memories that ultimately determine performance. Samsung has claimed in the past its multi-core design yields better performance under multitasking workloads but I'm guessing that's more marketing than substantive.

The enterprise version of the 830 enables full-disk encryption (AES-256) however Samsung's product literature doesn't clarify whether or not the same is true for the consumer version.

The Drive

The SSD 830 is the consumer version of Samsung's recently announced PM830. The two drives use identical hardware but they do differ in initial firmware revisions. Samsung will provide firmware updates (Windows only) via its Magician Software. Users are also able to configure the amount of spare area on the drive using the Magician toolbox. By default spare area is set at a standard ~7% (just what you get from the GB to GiB conversion), putting the 830 on par with Intel and Crucial in that regard.

The Samsung SSD 830 will be available to consumers starting in mid October. Although Samsung isn't announcing pricing at this time, I've been told to expect the drive to be priced around where the SSD 470 is today. I popped over to Newegg to do a quick price check on the 470 and came away relatively pleased:

Newegg Price Comparison
  256GB 128GB 64GB
Samsung SSD 470 $384.99 $214.99 $114.99
Crucial m4 $379.99 $196.99 $94.99
Intel SSD 510 $569.49 $279.99  
OCZ Vertex 3 $439.99 $209.99 $134.99

For the most part the SSD 470 is priced competitively with the Crucial m4 and OCZ Vertex 3. Crucial is a bit cheaper across the board but the gap is at most $20. If Samsung can keep its 830 pricing on par with where the 470 is today, I'll have absolutely no complaints.

The 830 will be available in four capacities, each of which will be available in three different versions: bare drive, laptop installation kit and desktop installation kit. The bare drive will be the cheapest option while the laptop kit gives you Norton Ghost + a SATA to USB cable and the desktop kit gives you Norton Ghost + a 2.5" to 3.5" adapter (with SATA cable).

NAND Type 2x-nm Toggle MLC 2x-nm Toggle MLC 2x-nm Toggle MLC 2x-nm Toggle MLC
NAND 512GB 256GB 128GB 64GB
User Capacity 476GiB 238GiB 119GiB 59GiB
Random Read Performance Up to 80K IOPS Up to 80K IOPS Up to 80K IOPS Up to 75K IOPS

Sequential Write Performance Up to 400 MB/s Up to 400 MB/s Up to 320 MB/s Up to 160 MB/s

Samsung sent us a 512GB drive, however as you can see from the table above the performance should be identical to the 256GB version. We are trying to get our hands on lower capacity versions as well to see how they perform.

The 830 is a very pretty drive, something Samsung is quite proud of. The 7mm chassis is all plastic save for the aluminum top plate. The bare drive doesn't ship with an adaptor for 9.5mm bays. If your notebook requires a 9.5mm drive you'll need a carrier of some sort to make the drive fit. There are no screws on the 830, the top plate just snaps on/off:

Inside the 512GB drive are only 8 NAND packages occupying one side of the PCB. These are octal-die packages with 64GB of total NAND per package. Each die is obviously 8GB in capacity.

    As far as I am aware, Intel and Samsung were the only drives compatible with XP and every other OS out of the box

    Am I wrong on this point?

    I believe ALL other SSD's require Partition Alignment for compatability

    It would be nice to get an update to see if ANY newer 6Gbps are compatible with every OS out of the box like the Samsung 470 and Intel drives

    Is there a compatability list floating around somewhere Anand?

    A Google Search turns up no reliability issues from anyone who actually knows what they are doing either

    If you want to find hundreds of reliability or compatability issues, just visit the OCZ Forum or go read the Newegg reviews

    or go sleep it off

    EVERY SSD should be 4KB aligned for best performance.
  • Out of Box Experience - Wednesday, October 5, 2011 - link

    Intel and Samsung SSD's do not require end user alignment

    Only SSD's that do not have the offset in firmware require alignment

    I like your mic.

    Quite a bit more juice running through them than the other drives - is this partly from the 256 mb cache?
  • tipoo - Saturday, September 24, 2011 - link

    Even the most power hungry SSD's don't require any additional cooling. It may look big on the graph, but that's still sucking way less power than most things in your system like the processor, graphics chip, etc. It just won't produce that much heat.
  • sequoia464 - Saturday, September 24, 2011 - link

    Thanks, Reason I asked is that My Toshiba based Kingstons seem to run (at least to the touch ) cooler than my both Intels and Vertex2's. (not that they are hot by any means, just warmer).

    Probably the workload and usage that is at play here - now that I think about it.
  • name99 - Saturday, September 24, 2011 - link

    Different people have different concerns.
    Yes, if you install this in a desktop box power is not an issue.

    If you install it in a laptop, the concern is probably not the thermal load but the maximum power draw. If your laptop is not specced to handle that, you'll find the machine crashing when you do a lot of back-to-back writes.

    Same thing if you hoped to use it in a USB enclosure, whether USB2 or 3.
  • Jaybus - Tuesday, September 27, 2011 - link

    Probably a combination of things. Certainly, the DRAM is much larger than what is used by the other drives. Also, notice that this 512 GB version is being compared to 256 GB drives, so right off the bat its flash is taking twice the power as those it is being compared with. This was mentioned in the article. Samsung has not yet supplied a 256 GB version for testing. So I doubt it is a controller issue. Probably just the fact that it has twice the flash.
  • infini - Saturday, September 24, 2011 - link

    I don't think Intel is the king of reliability with the 8mb problem of the 320 series. Beenthere can you provide a link with compatibility and reliability problems of Samsug drives?
