Samsung SSD 850 PRO Conclusion

IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.

Our first rating is performance, which compares how effective the Samsung SSD 850 PRO performs in benchmark operations against competing SATA-based solid state drive storage solutions. For reference, Samsung specifications suggest 550 MB/s maximum reads and 520 MB/s write speeds from 256/512GB/1TB Samsung SSD 850 PRO models. In our storage benchmark tests this solid state drive performed beyond this speed, producing results that surpassed the fastest SATA-based products previously tested. ATTO Disk Benchmark tests proved the 256GB Samsung SSD 850 PRO was good for delivering 566/537 MBps peak read/writes speeds, and the fastest performance we’ve recorded from any SATA-based drive. Linear testing with AIDA64 Disk Benchmark produced 508/479 MBps, finishing at the very top of all results. Sequential read/write speed tests with AS-SSD Benchmark produced 515/488 MBps, and again the 850 PRO topped our charts.

The Samsung SSD 850 PRO solid state drive sent to us for testing is advertised to deliver up to 100,000 random 4KB read IOPS, and 90,000 random 4KB write IOPS from its 3-core MEX controller. Using Iometer operational performance tests configured to a queue depth of 32 outstanding I/O’s per target across 100% of the drive, our benchmarks produced 94,985 combined IOPS performance. This result surpassed the previous best performance by almost 7000 IOPS, and enabled the Samsung SSD 850 PRO to secure a distanced lead at the top of our charts. Looking at 4K 32QD test results using AS-SSD and CrystalDiskMark, the 256GB Samsung SSD 850 PRO established itself as a truly dominant product by once again outperforming all the other SATA-based drives we’ve ever tested and posting impressive results.

Performance for the Samsung SSD 850 PRO can be easily summarized using one word: Superior.

Solid State Drives are low-visibility products: you see them just long enough to install and then they’re forgotten. Like their Hard Disk Drive counterparts, Solid State Drives are meant to place function before fashion. Anything above and beyond a simple metal shell is already more than what’s expected in terms of the appearance. Samsung has created a sleek 7mm profile with an elegant deep black finish on the Samsung SSD 850 PRO series. As solid state storage controllers become faster and more advanced, heat dissipation through the enclosure walls may demand that chassis designs become more beneficial than they previously needed to be. For now, the adaptive thermal monitoring system on the 850 PRO suits it well for managing heat in ultrathin and embedded designs.

Construction is probably the strongest feature credited to the entire solid state product segment, and Samsung emphasize this quality. Solid State Drives are by nature immune to most abuses, but add a hard metal shell and the chance for failure is reduced to internal component defects. If there are ever any problems with any Samsung SSD 850 PRO during the industry leading 5-year warranty period, end-users may visit Samsung Support or create a Service Request.

As of July 2014, the Samsung SSD 850 PRO series launches in the following capacities and retail prices:

Description Capacity Model MSRP
850 Pro Series SATA III 2.5″ 128GB MZ-7KE128BW $104.99 (Amazon | B&HNewegg)
256GB MZ-7KE256BW $179.99 (Amazon | B&H | Newegg)
512GB MZ-7KE512BW $349.99 (Amazon | B&HNewegg)
1TB MZ-7KE1T0BW $599.99 (Amazon | B&HNewegg)

I must admit that the Samsung SSD 850 PRO was a pleasant surprise. Considering that so many of the recently launched solid state drives have failed to offer substantial improvements over previous offerings, it was refreshing to see Samsung deliver a record-breaking SSD that also comes with an industry leading warranty. The Samsung SSD 850 PRO may not offer the industry’s least expensive price per gigabyte among solid-state storage devices, but 850 PRO also avoids being the most expensive. Considering that no other SSDs can deliver sustained transfer speeds or operational performance to the same level, it’s nice to see prices are reasonable. Benchmark Reviews recognizes how well the Samsung SSD 850 PRO series delivers highest-end operational performance to power users by topping our IOPS and transfer speed test results, proudly earning our Golden Tachometer Award.

    If you can find your way past the numerous prompts to get to SSD support you “might” be able find the right person to answer your question.
    Don’t bother buying an SSD if you are using a NVIDIA controller. Think about getting a separate controller such as a SIIG as a partial work around the compatibility and speed issue.

    1. Olin Coles

      NVIDIA chipsets are decent, but they just aren’t as competitive as Intel or AMD boards. All of our testing is done on Intel chipsets, and I’ve had good experience with AMD motherboards, but I wouldn’t suggest NVIDIA-based motherboards for much anymore. Sorry!

    Samsung has updated their MSRP listings:

    128GB – $129.99 USD ($1.02/GB)
    256GB – $199.99 USD ($0.78/GB)
    512GB – $399.99 USD ($0.78/GB)
    1TB – $699.99 USD ($0.68/GB)

    1. Olin Coles

      The prices we published were those sent to us last night. If they’ve changed in the few hours since then, it’s only on paper. The only prices that matter are those at places like Amazon and Newegg.

    2. Olin Coles

      It turns out the prices we published were exactly correct, and match those found at Newegg and Amazon: http://amzn.to/1lCj1je

    Enable RAPID and nearly double those performance scores.

    1. Olin Coles

      RAPID would add system-supplemented performance to the benchmark, and would not be appropriate for a SSD review that compares apples to apples.

      1. Hank Tolman

        RAPID Mode actually doesn’t use the SATA channel to improve performance. It uses up to 1GB of RAM to cache data. RAPID mode analyzes all storage related activity by inserting itself as a filter driver in the Windows storage stack. It provides RAM caching based on a number of factors, like access frequency, file types, system status, and RAM availability. It also caches the ‘hot data’ across sessions and reboots.

        I consistently get 900+ MB/s using RAPID mode, but it doesn’t represent real SATA performance since it really just intelligent RAM caching.

    It’s fast, but the question is, is it worth paying almost 2 times as much in terms of capacity:cost as much as the MX100?

    – The MX 100 offers power loss protection
    – There is limited end to end data protection too in the MX100

    Against this, there’s the SSD 850 Pro, which is very fast, and has 40 nm NAND (which lasts longer).

  5. Caring1

    I’m still trying to figure out the difference from the 840 Pro.
    Didn’t that also come with Magician software and Rapid Mode?
    The Read/ Write figures look the same, so does the IOPS.

    1. Olin Coles

      Read the review. This is explained in the first two paragraphs, and also at the end of page two. Hint: 32-layer 3D V-NAND Flash, 200% write endurance in Total Bytes Written (TBW), and active write power has been reduced by up to 40% due to Samsung 3D V-NAND technology.

      1. Caring1

        Yep, I read the review before my previous post thank you.
        Strangely the article stated this > “Benchmark Reviews tests the 256GB Samsung SSD 850 PRO against the fastest solid state drives available.”
        Yet omitted to include the 840 Pro. Funny that considering what I already pointed out, the figures look the same!

  6. Stormprobe

    This review says it has a 5-year warranty, but it actually has a 10-year.

    1. Olin Coles

      That detail was published exactly how Samsung supplied it, so if they’ve increased the warranty it was done so after the product launch. Myself and others would like you to reference your source for this information.
