    Default SSD Flash question

    Hey

    I'm aware of the difference between asyncron and syncron flash on SSDs .. but there are a lot of extra types I'm not fully aware of what are - maybe someone could enlighten me.

    When searching on a site like gh[dot]de i can chose between these options:

    MLC, MLC Toggle, MLC asynchron, MLC synchron, SLC and eMLC

    In the end it comes down to 2 models anyway for me .. getting another Corsair Force GT 120GB or as alternate option and 12euro cheaper the Mushkin Enhanced Chronos 120GB (MKNSSDCR120GB).

    On paper (specs) the Mushkin is slightly better on IOPS, but uses MLC (all it states) .. so not sure here.

    thanks in advance

    i kept on researching myself (as i always do, even when posting questions) but didn't have much luck until I decided to scan other reviews of new drives for comparisons to the old .. and this is what i learned. Please correct me if I'm wrong.

    SLC = single level cell flash (out of the question for me)
    MLC = multi level cell flash (more density and speed)

    knew those 2 already

    MLC = MLC Asynchron .. 2 words, same things. (IMFT 25nm asynchronous flash) and the thing that confused me
    MLC synchron = also known as ONFi 2.x and the only affordable decent flash modules
    MLC Toogle = also known as ONFi 3.x and out of normal peoples price range (not jedec certified)
    eMLC = enterprice class MLC and also out of normal peoples price range.

    With that in mind, my choice is simple .. getting another Force GT 120gb as its the cheapest and best performing (on paper) 120gb model.

    SSD benchmarks can be misleading and confusing at best. Asynchronous NAND will have scores similar to synchronous NAND, but the asynchronous drives will have inferior real world performance as the drive's free space decreases.

    Take a look at the benchmark scores in OCZ Technology Octane 128GB Solid State Drive Review :: TweakTown USA Edition and you'll see some scores vary widely depending on the test. On paper, the Crucial M4 specifications and some scores don't look look impressive, yet they are highly rated by users and in most if not all reviews.

    If I upgrade to an Ivy Bridge system, I'll probably go with a Crucial M4 128GB o/s drive.

    yea, the crucial has been in my considerations as well the first time .. dunno why not this time (prolly cause when searching it falls out of range on the 500mb/s read and 350mb/s write specifications and thereby wasn't included in my searches).

    Euro/GB its slightly cheaper then the Force GT (1,158/GB vs. 1,187/GB). My goal was to stay below the 1,2 euro/GB on this purchase.

    Even though this is the second time I pick a SSD, it hasn't become easier and is still the hardest pick on hardware purchase in my book. Sooo much reading and not a lot smarter in the end .. hehe :)

    Miss the comparison charts for ssd's here on TT, so had to go "outside" to find some. Think this one sums it up pretty well: Corsair Force GT 240GB & Crucial M4 SSD Update - HotHardware

    Seeing as I already have a Force GT and I know it performs well, I think I'll upgrade with one more of those. The mentioned review is a couple month old and I know a lot can be done with FW updates (but corsair has also newer ones since then) ... but seeing as the price is pretty much identical (in Germany at least, where I'm going to order from) I think the corsair is the best choice.

    Will allow me to free up my 60gb ssd and move it to "Snuggles" to have a virtual silent HTPC in the bedroom - my main goal in this purchase (and will do just fine even though its async as it just has to run VLC to play from my NAS and FireFox with 2-3 tabs open max)

    Asynchronous?
    The Corsair Force GT models use synchronous NAND.
    Their Force 3 models use the inferior asynchronous NAND.

    might have expressed myself badly, my current 60gb Patriot Pyro uses async. and I want to get that out of my main system. This is why I'm on the lookout for a new one.
    Going to move it to my HTPC though, cause its still fine for that.
