Samsung 840 Pro SSD: More Speed, Less Power, And Toggle-Mode 2.0

Benchmark Results: Power Consumption

Power Consumption: Idle

Fact: SSDs are so fast that they spend most of their time idle. During a recent virus scan benchmark we ran that lasted almost 30 minutes, the drive was only busy for 281 seconds. Consequently, idle SSD consumption is the most important power measurement to take in a desktop environment.

In our experience, the capacity of an SSD has almost no impact on its idle power consumption. And if past reviews taught us anything, it's that the same manufacturers tend to do well (or not) from one generation to the next, giving us a reason to get excited about the 840 Pro.

Samsung's 830 impressed us with its efficiency (high performance at low power). However, the 840 Pro takes things one step further. Not only does it best the competition, but it does so using the least amount of power at idle.

Power Consumption: PCMark

Power consumption during a workload is also a critical measurement, revealing a more complete picture of efficiency. It's impractical to log the energy use of an SSD over the hours it takes to run our Storage Bench v1.0. So, we're forced to rely on a shorter-duration run of PCMark 7. The results of this test mostly mirror what we saw in the first power chart, scaled up slightly. The difference this time is that capacity matters more. Larger models tend to consume slightly more power during use, though the outcome still largely lines up by brand.

Samsung impresses us yet again. The company's latest SSD consumes the least amount of power during idle and during use, all the while offering top-of-the-line performance. When it comes to power efficiency, Samsung's 840 Pro is the clear winner.

    Despite what the judges believe, Samsung is a great innovator. Unlike some fruity companies, that basically license other companies tech....

    Kudos to Samsung for getting ahead of the competition yet again. And the complete SSD is designed and manufactured in house! And thay are sure of its reliability, hence the 5 year warranty.

    I dont see why it did not get a Toms approved award.... its faster, uses less power, and offers better warranty than the competition. And the firmware is also stable, unlike SF.

    pocketdrummerThey keep increasing the speed, but they do nothing to reduce the COST.

    SSD prices are the lowest they've ever been and are dropping at a very rapid pace. Last year $1 per GB was unheard of, now you can find SSDs as cheap as $.60/GB and mainstream drives have been under $1 for a while. Only the top of the line drives are still more than $1/GB.

    4TB and growing, and I get plenty of use out of my SSD. People who claim SSDs are pointless for them are people who don't understand how they should be used. Leave your data on an HDD, and put the OS on the SSD.

    Forget loading your hundreds of GB of data files onto an SSD. Decent mechanical drives in RAID 0 perform nearly as well in sequential reads, which is what reading in your samples would be.

    Sounds like you need to stop complaining and start using the right tool for the job.

    Wow, Samsung was ahead of competitors with its 830 due to superior performance and low prices. Now I bet the 840 has, (or will) widened that lead.

    Probably because it still costs $600 for a pathetic 512gb of memory. Once you can get 512gb for under $200 and have a life span that gets close to a decent HDD, then you can expect an award.

    They keep increasing the speed, but they do nothing to reduce the COST. I would take an SSD half as fast as some that are out now if they cost me half as much and had a decent amount of storage. It's still pointless for someone like me who has over 1.5TB of space used. I can't load Windows and all of my critical programs on a 256GB SSD, and the 512GB wouldn't give me much wiggle room.

    So it's the Samsung 840Pro 256GB for C:, and it's the Seagate single-platter 1TB drive (ST1000DM003) for storage. Awesome awesome combo.

    Gah, 1 month after I get the 830 now comes the 840 Pro who gets another 120 mb/s in extra speed.

    To those that complain about SSD life span, the truth is that in 3 years(typical warranty of an SSD) you won't be using the same SSD because the new SSD will be 40-50% faster. 3 year from now I'd be using the 860 Pro with anyway and when an SSD reach end life it just can't write anymore, you can still read all the files onto your new SSD unlike a hard drive that just breaks down.

    So glad I didn't pull the trigger on a 830 yesterday...I came this close. For the performance gains of the 840 Pro, I can wait.

    pocketdrummer...pointless for someone like me who has over 1.5TB of space used


    You are not painting the greatest geek picture of yourself here :-)
    You must have heard that it is a good idea to have at least 2 drives, one OS and crucial programs and one or more Data drives?
    Photoshop even kindly points out that it prefers a separate scratch disk.

    I use a 90GB SSD and 2TB data drive and that works just fine with Win7/64, full Photoshop/Premiere install and a few choice other things; and still have some 30GB left over.

    I have over 30 TB of "data" sitting on an enterprise class NAS, that everyone on my network uses for extra storage and to access content.

    My PC does everything I need to do with 2x 256 GB SSD drives, and I am sure after using it for a year... that anyone else's can too.

    Upgrading both my drives to 2 of these 840 512gb drives would be huge boost ^^

    Don't get me wrong, I like Samsung SSD's but ~30% more expensive it's a tough choice, and for now I'd choose the OCZ Vertex 4. The real world in 4KB (most OS/Apps) doesn't justify it's price. Hopefully the prices I ran across are incorrect, but here's what I've found:

    Samsung SSD 840 Pro Pricing:
    $99.99 64GB, $149.99 128GB, $269.99 256GB, $599.99 512GB.

    Samsung SSD 830 Pricing:
    $74.99 64GB, $139.99 128GB, $219.99 256GB, $569.99 512GB.

    OCZ Vertex 4 Pricing:
    $49.99 64GB, $99.99 128GB, $199.99 256GB, $399.99 512GB.

    pocketdrummerOnce you can get 512gb for under $200 and have a life span that gets close to a decent HDD, then you can expect an award.


    Well, it seams samsung is doing a decent job on getting there. heck, In this article they even mentioned about there personal experiences with the 470

    Quote:
    We run Samsung 470s in all of our test beds in Tom's Hardware labs around the world, and not one of them has suffered any sort of failure.


    and the first ones launched about 2 years ago. So I'm just a few of those test beds has those early models. ;)

    pocketdrummerThey keep increasing the speed, but they do nothing to reduce the COST.


    Oh really? For the samsung 830 128GB I have, (if I bought it) it would of cost $200 to $250 when it first came out. (got my SSD through the samsung giveaway many months back, so I dont remember exact price of it at the time, other than it was above $200.)

    From the samsung 830 review
    Quote:
    We're told that the 128 GB 830-series drive should sell for $250. That’s a little under $2 per GB (right in line with OCZ's 120 GB Vertex 3).


    http://www.tomshardware.com/reviews/samsung-830-ssd-toggle-mode,3034.html

    So with the info from above, a samsung 830 128GB cost about $140 now and when it launched a year ago, i cost over $200.... They haven't reduced the cost at all?

    Lets rethink that about that. ;)

    (and thats just from samsung, I haven't looked at the other guys. Although knowing how companies react to each other that's in the same market, I'm pretty darn sure that i'll see the exact same trend.)

    pocketdrummer It's still pointless for someone like me who has over 1.5TB of space used.

    Something fishy with your thinking or something :heink:

    No matter what kind of job you can do with a computer, I've never heard of someone that would need 512GB of storage just for their critical programs or if they did, it wasn't critical enough to need the speed of an SSD (and with all the people i've hanged out with on the forums, I know there plenty of guys in there that really do use there storage systems to the limit (both speed and storage) by there jobs/activites).

    Now if your combining progams WITH anything you save. Then that's a different story.

    Although if that's your thinking then as Freggo and willard pointed out, For how long you been here, you should of know by now that you need would need to pick the right things for the job and truly figure out what needs the speed benefit of an SSD. (not every "critical program" needs the speed boost of an SSD. )

    The difference is Vertex4 has performance dependent on the capacity filled. Plus, OCZ are known to release not fully tested firmware. With Samsung, the firmware is rocksolid.

    Real World - you won't be able to tell the differences, most tasks <1 second, install a 7GB game <15 seconds. So if you're a 'Borg' then maybe...
