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).

Samsung SSD 830 Lineup
  512GB 256GB 128GB 64GB
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
Random Write Performance Up to 36K IOPS Up to 36K IOPS Up to 30K IOPS Up to 16K IOPS
Sequential Read Performance Up to 520 MB/s Up to 520 MB/s Up to 520 MB/s Up to 520 MB/s
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.

    Might have something to do with Apple's and Samsungs legal issues. They seem to be trying to kill each other at the moment and having your supply line coming from someone you are suing and being sued by, isn't a good idea. Has soon as those supply contracts are up Samsung may tell them to kiss their $%@#

    It's probably less of "killing each other" and more of haggling and "poker" between the two.

    By diversifying Apple can say to Samsung, "Go ahead, make my day".

    Wit most SSDs the size realy matters, why not just format a drive in to different size partitions.

    Format one partition to 120GB and fill the other 392GB partition up data so it cant be used for trim or any other optimizing benefits.

    Because I am sick and tired of these firms sending big SSDs that dont represent real world use, as I will never buy a +$700 512GB drive, the sweets spot for most people is around 120/128GB.

    I wane know how a 120/128GB drive preforms not a model that's way above my budget.

    Partitioning wouldn't affect the number of channels, which does affect performance quite a lot, so you'd end up with numbers that reflect no actual product at all.

    With Samsung's budget on these..

    EMC is using Samsung drive's in their enterprise storage products (Clariion) and they are the same sata drive's, except different stamp.

    If its good enough for the enterprise-class serious work than it sure is good enough for consumers.

    When's the availability for consumers?

    It seems that every SSD article I read on AnandTech ends with a plug for an Intel drive. I understand some of the logic there, but it's not like Intel has an unblemished reliability record. The 320 fiasco was just as bad as anything we saw with the Corsair or SandForce drives. And IMO the price premium of the Intel 510 weighs heavily against it in comparison to, say, the m4 or Samsung options.
  • Fun Guy - Monday, September 26, 2011 - link

    Agreed - the reviews at New Egg show Crucial to be top dog, with Intel somewhere near the middle.
  • JarredWalton - Monday, September 26, 2011 - link

    I can't take Newegg reviews seriously, though: "I bought this product with my own money, so now I have to praise it to avoid buyer's remorse." Sure, there are bad reviews and good reviews out there, but even taking the average review score at Newegg isn't as useful as a real review looking at benchmarks and comparing with other drives.

    Crucial is one of the cheapest SSDs and still offers good performance, which is what most Newegg shoppers are after. Intel on the other hand charges a price premium, which is precisely what Newegg shoppers don't like. Outside of the 320 "fiasco" (which is something we warn about with every new SSD), Intel SSDs have proven very reliable over time, particularly compared with their contemporaries. The G1 no-TRIM thing was Intel being greedy, but G1 still worked quite well for the vast majority of users (even if it could get backed into a corner where performance would tank). G2 wasn't the fastest in its day, but it was fast enough and rarely gets into the poor performance realm.

    Ultimately, if I'm putting my data on a device, I want it to be long-term reliable. So, I'm not buying any brand-new SSD or HDD. I let it stew for a couple months at least and then see if there are any issues cropping up. That gets you around things like SF-2200 issues, Intel 320, etc.

    "The G1 no-TRIM thing was Intel being greedy, but G1 still worked quite well for the vast majority of users (even if it could get backed into a corner where performance would tank)."

    In other words, it was a reliability issue because the vendor could not be relied upon to do the right thing.

    Anand you used a Intel h67 in your test bed and I am currently run a 990FX chipset. Due to budget I'm looking for a good 120GB SSD(OS drive), what would you recommend? Also I cant wait if there is something around the corner.
