Samsung 850 Pro SSD Review: 3D Vertical NAND Hits Desktop Storage

How We Tested Samsung's 850 Pro

Our consumer storage test bench is based on Intel's Z77 Platform Controller Hub paired with an Intel Core i5-2400 CPU. Intel's 6- and 7-series chipsets are virtually identical from a storage perspective. We're standardizing on older RST 10.6.1002 drivers for the foreseeable future.

Updates to the RST driver package occasionally result in subtle performance changes. They can also lead to some truly profound variance in scores and results as well, depending on the revision. Some versions flush writes more or less frequently. Others work better in RAID situations. Builds 11.2 and newer support TRIM in RAID as well. Regardless, results obtained with one revision may or may not be comparable to results obtained with another, so sticking with one version across all testing is mandatory.

    I 'just' ordered 2x Samsung EVO 120GB a few hours ago, then I stumbled onto this article. Damn it! Damn it! Damn it! Every freaking time I run into this, be it Storage, CPU, or GPU.... -_-

    I don't know if this really changes anything for you. Two EVOs are still going to be better than one 850 Pro in every way. But I understand the sentiment!

    You just ordered a few hours ago. Just cancel your order if you really want this 850 Pro.

    I can guarantee that in 10 years you won't own that drive anymore. :lol:

    I still have several 8-10 year old drives laying around between 80GB-150GB. I mostly use them as external drives for backing up USB thumb drives and other files that aren't large volume.

    Hoping for some SATA 12gbs (or more) transfer speeds in the coming years.

    Will overclocking the bus that the sata controller is on impact the performance?

    Can you test on an AMD platform which makes it easier to over clock that bus and some of the connected components?

    Looking forward to future generations of 3D Vertical Nand on M.2 / M.2 Ultra interface. Too bad SATA 3 is all maxed out and the next generation standards are not yet mainstream for the masses which is holding back SSD performance. As far as this drive goes, it's only slightly faster than MX100 but costs double. I don't think it's worth it. MX100 512GB sounds like a perfect stop-gap until M.2/SATAe drives arrive with 1-1.5TB/sec throughput. Perhaps Samsung will give us 95% of the performance for a fraction of the price in the 850 EVO.

    Not quite. One is for my Desktop, the other is for my Father's Desktop.

    For my Desktop, I'll be stepping up from 2x OCZ Vertex 2 60GB in RAID 0. Hope it'll be worth it...
