    Hi, I recently purchased a Clevo w230st without a hard-drive and am looking for a large, high performance ssd to use as my daily driver. I am tossing up between a 512gb 840 pro $490 or a 750gb 840 evo estimated at around $530. How much slower is the evo to the pro?, would buying the 1tb version be worth it (it seems to be faster than the 750)? and how reliable is the new flash technology?, thanks

    I see a little improvement with the 840 pro over lesser SSD's, but only when dealing with large writes, which isn't very often for most users. A majority of the time you wouldn't notice one being faster than the other.

    The evo is new, but samsung has a good track record of reliabilty with SSDs.

    EVO and PRO is similar in speed on everyday tasks with the PRO being slightly faster.
    PRO have MLC NAND, EVO have TLC NAND. Difference is that MLC have higher life expectancy. But, TLC will outlast all of the other components in your notebook anyway so its a moot point.

    EVO have today support for RAPID through Samsung wonderful Magician software, that let you use 1GB of your RAM as cache for insane speeds way faster than any SSD out there :)
    PRO is said to get RAPID support later, but nobody knows when.

    EVO and PRO share the same controller, but EVO have the controller running at faster clock speed, so thats something.

    You cant go wrong no matter what you choose. Samsung SSDs is the best you can get :)

    Im extremely happy with PRO. The snappiest SSD I have ever owned

    Cloudfire, the PRO and EVO lines are not similar at all. (Curious as to what other SSD's you've owned)?

    For one, the EVO goes to below USB 2.0 speeds when pushed hard (the Pro doesn't get hit that hard).

    See:
    AnandTech | Samsung SSD 840 EVO Review: 120GB, 250GB, 500GB, 750GB & 1TB Models Tested



    The software (RAPID) that you seem to be in love with is not a solution for real work (that actually pushes the storage subsystem).

    The best SSD right now is the SanDisk Extreme II.

    From the same link:

    And here is tiller again with his workload that doesnt apply to OP or any of the normal SSD users.
    Im not having this discussion with you again tiller. Isnt it time you start giving people advice based on normal SSD use?

    As for the review you link to:
    A) Samsung use the EXACT same architecture on PRO and EVO.
    B) it is the same controller, based on Cortex R4, but is clocked higher than the Pro controller
    C) the difference is TLC and MLC

    And if you read the conclusion from the Anandtech review
    I have owned X25M G2 and M4 earlier, and PRO beats them both in snappiness

    What workload are you talking about? I sure didn't mention one. Try to read for comprehension, okay?

    No, it is not EXACT: the TLC nand is simply inferior when performance is the goal.

    Even the quote you have shows how little you understand the things you read. A lot of ifs in that statement and mainstream SSD is not the same as what the OP is asking for: a HIGH PERFORMANCE SSD - not your latest software enabled benchmark 'king'.

    You are posting your usual BS as always.. You linked to QD32 workloads (like you did on our earlier discussions) which very rarely apply, you totally disregard that both Samsung EVO and PRO is the top performers on light and heavy workload (which matters).

    I have a real world tests of EVO where it even beats the PRO.

    You keep talking down on RAPID because it doesnt give boost to real work ("push the subsystem"), which again is one of your misguided and moot points because it doesnt apply to most users again.

    So lets summarize: EVO Is a high performance SSD which you obviosuly should have known if you read the reviews or even have seen the specs. It also have RAPID which puts it above the competition.

    Why dont you go seek out a forum that is about servers, industry workloads and such? That way you could write about QD32 and putting massive workloads on the SSDs, all your heart desire

    When an M4 is just as quick as a Samsung 840 Pro - that is not a top performer. The EVO is below the 840 Pro, no matter what the 'scores' say...

    When software makes a better solution than the right hardware, let me know (hasn't happened yet).

    When you have it straight that TLC requires tricks and workarounds to seem better than MLC - I'll stop posting.

    I'm not talking about servers or industrial workloads - you are.

    Try to stay focused on the discussion at hand - you still haven't answered what and how many SSD's you own(ed).

    "Try stay focused on the discussion at hand"
    Hahaha that says the guy who always destroy on topic discussions with his rant about how great Intel drives is and how much consumer SSDs suck at industry workloads.

    I dont know how many times people have tried telling you this, but you keep going on like a broken record.

    Anyway im out. it is useless to have a discussion with you.

    OP: sorry about the discussion in this thread. Just read my first reply in this post.
    Pick either EVO or PRO. Doesnt matter, both are very good drives. And both will get RAPID :)
