Samsung 840 EVO SSD Review – Samsung Caches In On Value and Performance

Our SSD analysis today is perhaps the most detailed typical SSD report we have published to date, and so it should be.  Actually, the word ‘typical’ doesn’t quite fit as the Samsung 840 EVO SSD, that I am now using as my mainstream system drive, is pushing over 1GB/s sequential speeds and an unbelievable 685MB/s low 4K random write performance.  If you think this might be magic, you would be right and this magic is within the reach of every Samsung 840 EVO purchase, performance not even closely matched prior to this release.

The magic of the Samsung 840 EVO SSD comes in the form of caching, initially with their proprietary TurboWrite Technology and then later with installation of their RAPID Technology through Samsung Magician software. To be brutally honest, I have never been a fan of caching when it came to SSDs.  Sure NVELO pulled some great things off with Dataplex where they were able to bump HDD speeds up to that of the SSD when used as a caching medium, but for the most part, caching in the HDD hybrid/SSD arena just didn’t cut it.  Today might be a new day.

REPORT PROGRESSION

Perhaps our biggest dilemma, with respect to the Samsung 840 EVO SSD, was whether to encompass it within one report or several.  There is really that much to discuss.  Our end result is a page by page progression of the EVO bringing you through such things as the Introduction and Features, SSD Components, Test Protocol, Performance and TurboWrite Explanation, Standard Benchmarks, RAPID Technology Explanation, Enhanced Benchmarks and then our Report Summary and Final Thoughts.  If you find yourself seeking a specific piece of information, simply thumb through the pages until you find the heading that you seek.

PACKAGE CONTENTS AND PRICING

The Samsung 840 EVO SSD is a SATA 3 (6Gbps) solid state drive that is backwards compatible to SATA 2 and comes with a three year warranty.  It is a 7mm thick form factor that can be purchased as a standalone SSD, or with notebook or desktop migration kits.  It will be available in capacities of 120, 250, 500, 750GB and 1TB and MSRP is $109, $189, $369, $529 and $649 with migration kits typically adding $10-$15 to the price.

POWER CONSUMPTION

Power management of SSDs seems to be of interest to many consumers as of late and Samsung has done their best to ensure great battery life through a typical power rating of 11mW and idle at 45mW for the 840 EVO.  Considering that laptop SSDs are idle for 95% of the time, idle power consumption is key as it, not only extends battery life but also, reduces heat as well.  In idle time, the Samsung 840 EVO uses 11 times less power than a hard drive.

    Hi Les, just curious – in terms of real world performance – would you go for a SanDisk extreme 2 or a Samsung Evo 250gb? These are the 2 i’m looking at. Based on the specs the Evo wins hands down but is this the case for real world performance? Is everything “lightning fast” in loading and booting?

      I might go with the Samsung myself.

    Am pleased to hear this; because I have just finished building my i7 4770 Sabertooth Z87 PC and This SSD running Test Windows 8.1 and the Samsung Magician software told me the SSD RAPID MODE is not supported, which seemed odd as this is the Samsung software for the SSD.
    Patience is a virtue which brings rewards.
    I hope 20% of 128 GB is enough Over-provisioning.

    Les, I’ve noticed a lack of reporting on any “real world” experiences with RAPID mode turned on. Benchmarks seem amazing with RAPID, but can any of that be felt in real world use? Or does the feature blur the line even further between what’s seen on benchmarks and what’s experienced? Ie. making something really fast, faster, will still be really fast.

    Hey Les, I’m looking to build a RAID 0 out of 2 drives to write WAV files to via a DAW such as Pro Tools, Ableton, etc. Would you recommend the 840 Pro or 840 Evo for such a setup? Thanks.

    • http://thessdreview.com Les@TheSSDReview

      Definitely 840 Pro my friend.

      • Sai

        Now that the 840 Pro has RAPID too, there’s no reason not to get it.
