Samsung 840 EVO mSATA Review: 120, 250, 500, And 1000 GB, Tested

Test Setup And Benchmarks

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.

    Now all we need is the price to drop, then I'll get one.. ;)

    Maybe it's time to upgrade the HD of an old working notebook to SSD! But will a Core2Duo processor bottleneck a SSD?

    @blackmagnum: You don't have to worry about your processor being a bottleneck, but rather, your system's SATA interface. It is highly doubtful that your Core 2-based notebook (much like my own) has an m-sata slot, and the 2.5" bay for a HDD would have a SATAII port, not SATAIII. So the overall max read/write rates would be cut in half. But to answer your question in another way, tom's posted an article almost a year ago on the subject of upgrading older systems with an SSD: http://www.tomshardware.com/reviews/ssd-upgrade-sata-3gbps,3469.html

    @blackmagnum: You be glad to upgrade your hard drive to a SSD drive. Did it for my goddaughter's after she had a hard drive crash and it runs a lot faster then before.

    Interesting article. It coincides with the current shift from desktop pc's to mobile pc's.

    But aren't we already moving to M.2. Why can't I buy Samsung XP941 :(

    "The latest version offers RAPID support to non-EVO drives like the 840 Pro."Got my hopes up there. The standard 840 series SSDs are NOT supported. The article didn't explicitly state they were, but what other drives (aside from the 840 Pro and EVO) have Rapid support? Perhaps "The latest version offers RAPID support to both EVO and 840 Pro SSDs." would be more accurate.

    "This company has a track record of disrupting the markets it enters; now that it's focusing attention on smaller form factors with enthusiast-class hardware, it's only a matter of time before we start seeing M.2-based offerings as well."This is mainstream hardware, I don't know any enthusiats who will settle for drives with TLC NAND.

    It is nice to see these finally available. I've been watching the Crucial m500 mSATA drive for a while, and the 480gb version frequently falls under $300 on NewEgg, which is competitive with 2.5" SSDs.

    "Enthusiast" to me doesn't automatically mean getting the fastest, biggest, bestest, craziest parts regardless of price. It also means people who put a lot more thought into their systems and thoroughly weigh all their options. MLC, TLC, or not, the fact remains that the EVO is a fast, reliable drive for a good price.

    Your argument sounds similar to, "I don't know any enthusiasts who will settle for LGA 1150 instead of LGA 2011," or "I don't know any enthusiasts that would settle for a non-K CPU."
