Samsung SSD SM825 400GB Enterprise SSD Review – 3Gbps eMLC Data Center Edition

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

ATTO benchmarks returned results slightly lower than advertised specifications which were 224MB/s read and 211MB/s write transfer speeds.  This is a bit unusual as, in typical consumer SSD testing at least, ATTO had always provided the highest overall performance simply because of its use of highly compressible data.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.  We have provided  incompressible (random data) results:

We are starting to see much better performance when testing with incompressible data.  The performance  seen here of 253MB/s read and 205MB/s write are excellent results.

AS SSD BENCHMARK VER 1.64

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it tests in the worst case scenario for the most part with incompressible data.

AS SSD is the toughest test around for transfer speed performance and, to once again see those high sequential scores, is a huge plus for the Samsung SM825; this rarely being seen in any consumer SSD.

  1. The word coming from Digitimes is that Samsung is not about to see its NAND lead eroded, and their new fab, dubbed Line-16 should give Samsung a leg up.

    Located in the Nano City Complex in Hwaseong in South Korea, the fab will be capable of producing 200,000 12-inch wafers every month.

    Samsung began work on the site back in May 2010, and it is now expected that the site will be up and running in two months.

    According to chip expert at Future Horizons, Malcolm Penn, the opening is indicative of how important the NAND sector is.

    “It used to be DRAM, DRAM, DRAM ;now NAND is growing around 50 percent faster.”

    “They are pretty much neck and neck now with Toshiba so it is very important for Samsung to get more capacity online.

    “Capacity equals market share, so if you have a bigger fab then you are going to get ahead, and the Samsung fab is a monster.”

  2. This Fab is open an operating.

  3. Toshiba has as much as admitted that they will have a tough time competing with Samsung’s new fab. Toshiba wants to expand also; but their costs to expand will be far greater than Samsungs. Advantage – Samsung

  4. You might want to look into the life span on the SuperCaps used. There is a reason why everyone else is going to digital caps, something to do with the SuperCaps only lasting two years 🙂

  5. Where can you buy this?

  6. Agreed asw. This would be a great product if you could actually find somewhere to give you pricing on it, let alone actually buy one.

    Even several months after this review, no one seems to know anything about buying one.

    • It is an enterprise product and available with contact through Samsung Business.

      • Thanks. I’ve got a request in to Samsung Business. We’ll see how long they take to get back to me.

      • HOLY COW buying these things is VERY different than just going to newegg and putting in your credit card and then they ship them to you. I had to dig up memories from days gone by and put on my old reseller hat…

        For posterity’s sake, here’s what I’ve gone through:

        In a nutshell, it’s taken a week, and I FINALLY have an MSRP on these things. I was wondering if they were in the realm of the Hitachi eMLC (SSD400M) drives or more along the lines of the OCZ Deneva’s. (Hint, they are pretty much right in the middle.)

        Anyway, Samsung has a few distributors in the USA – many of which won’t deal with “small” purchases (we’re looking at 44 of these things, and they consider that quite small). I ended up at Arrow, but Avnet would have worked too. (I think there are 3 in the US. Crestone is the company that supplies the other 3).

        If you don’t know how the channel works, prepare to be mired in red tape.

        I also finally got a call back from Samsung itself. I basically had to sell what we were doing with the product to them. Don’t get me wrong, the guy was very nice and quite helpful, but we’re not usually the kind of place they would sell to. If you’re not a NetApp, EMC, HP, Dell, Oracle, Cisco, etc, well, they’re not quite sure what to do with you. The guy explained that they couldn’t be expected to send an engineer from Korea to diagnose problems and then produce custom firmware for with such small quantities ordered. I told him I just want a bunch of fast reliable enterprise drives… Custom firmware not required…

        IMHO, you’re probably better off waiting for these drives to come to your preferred storage vendor. Enterprise just moves more slowly than consumer. In other words, although this drive was released in late 2011, it’s still considered a new product, and the channel is still trying to figure out how to handle/sell it. But, if you’ve got a definite need for a bunch of these, it is perhaps possible to acquire them. Just be prepared to exercise extreme patience.

      • I always suggest buyers to contact us with such purchases as our contacts can usually help significantly, however, yes…this is not a NewEgg purchase.

  7. still cant found it stock… only reviews is it real device or not?
