Samsung Goes 6 Gb/s: Is The 830-Series SSD King Of The Hill?

Benchmark Results: 128 KB Sequential Performance

SSD manufacturers often want to stress random performance because they clearly decimate conventional hard drives. Sequential performance is a little different, but still represents an important aspect of the performance picture.

But how pervasive is sequential performance for the average user? Take a look at the graph below; it shows the distribution of all the seek distances from one of our traces.

The first thing you'll notice is that there's a preponderance of activity zero sectors away, which means that our trace is made mostly of back-to-back requests, or sequential I/O. If the trace was 100% random, none of the accesses would be zero sectors away.

Intel's 250 GB SSD 510 leads the pack in reads, but the 256 GB 830 follows closely behind. Samsung's sequential write performance, though, is simply impressive. The company's latest SSD unseats the HyperX and Vertex 3 for top billing. Kingston and OCZ both employ SandForce's compression technology to reach that level of performance; Samsung doesn't enjoy the benefit of DuraWrite technology. Instead, the 830 relies on its improved controller and the Toggle-mode NAND that we already know yields the best throughput for its performance.

Don't be completely dissuaded by these lower performance results. They're not new-in-box numbers; they represent steady-state performance, which changes the behavior of the SSD. This is a particularly bad scenario because the testing happens after each drive is filled with incompressible data, but before idle garbage collection is able to help recover performance.

As most of you know, SandForce's architecture is most efficient when it's operating on compressible data. In the real world, that's actually a pretty realistic expectation of what it'd be working with most often, making these results, again, a worst-case situation for the SF-2200-based drives.

    With all of these fast SSDs coming to market, I can only hope that the competition starts to drive down prices soon.

  • I still opt for the M4 in all the enthusiast builds I do!

    It boils down to reliability, not one hiccup on M4 yet (or any crucial drive Ive installed), 4/5 Sandforce drives I have installed have had some form of callback problem to resolve once deployed, mostly requiring firmware updates, but a few failed drives as well!

    Mind you, still better than the early Corsair force Series I used, every single one failed! Stopped using them quick!

    Am tempted by OCZ, once they have reliability on their side I will give them a go again!

    Looks like a really nice SSD. Samsung has one of the best validation proceses along with Intel and Crucial so I really don't expect people to have issues like they do with OCZ drives. Now the real question how much will it be on the egg?

    I saw this quote below in the summary and laughed as nobody in there right mind would use a basic MLC drive in a database server. So Samsung tuned the drive for what it will be used in ,desktops, good.
    "Although we'd probably think twice before picking this as our first choice for a database server, it does just fine in an enthusiast's machine."

    When will we be seeing articles like: SSD price slashed 50%?

    great review. now we just have to wait and see how the ssd will hold up over the long haul. If it is anything like the 470, then it should be problem free.

    Make it $1 per GB at least

    We'll see how this series of Samsung SSDs fair. The previous gen was a nightmare of problems so I don't think Samsung's validation process is any better that the rest of the SSD suppliers - which is sad when Samsung controls everything including NAND production. It's amazing that we still have SSDs NOT readt for Prime Time.

    Proof? I think you just pulled this out of your ass or from someone's that told you some story. The 470 series was VERY reliable.
