Hay,

Ok, The new Samsung Electronics 840 EVO-Series, There is anyone test in Raid10?
Interesting pretty and Fast! But Looks like there is software issue there!

Sequential Read Speed 540 MB / Sequential Write Speed 520 MB / Random Read Speed 98K / Random Write Speed 90K

  • What software issue?

  • i dont have one in raid 10

    but im using it for my main SSD

    this is what I get running the Samsung bench test

    not one issue i've had thus far ... been using it for a while now (since day it came out)

    looks Good! I'm looking to provide SSD as soon as my vPanel v2 coming!.

  • That is some fast drive... I thought my macbook air 2013 had fast ssd 750 MB/s :)

    Unfortunately only due to the cache and only on Windows, that is. Not on RAID and not on any other OS.

    RAPID Mode Maybe?

    1056 MB/s ?! Wow!

    Anyone use these connected to an LSI hardware controller yet?

    You mean RAID?

  • hosthatchhosthatch Patron Provider, Top Host, Veteran

    Yes it is because of the rapid mode which uses some type of caching (haven't done a lot of reading). The drive is actually around 500MB/s itself. The caching mode is only available on Windows and does not support RAID.

    In LSI or any other RAID, it will be ~500MB/s.

    Rapid Mode Cache I guess.

    500MB/s not bad :)

    One thing is for sure, you can't beat the price of the EVO series. Cheap!!

    he is talking about Samsung 840 EVO and "RAPID" caching, which uses up to 1GB of your RAM to speed up access to some data, thus you see some weird results over 1000MB/s what is faster than SATA can achieve. Anyway you need software to enable that and this software is available only for Windows.

    PS. looks like I took quite long to write and many people answered before :P

  • Don't rain on my parade (my EVO SSD speeds)

    it's what gets me through the day (kidding, or am i...)

    TLC are less expensive (samsung did experience with the 840 basic) but depend more on software features. So I would wait a little more before adopting them in massive deploy ;-)

    We pretty much stick to Intel. Their reliability can't be matched.

    yes they are good, we used a lot of intel last year.

    The 3500's are kind of a downer compared to the 520s.

    agree, the 520 is very good :-)

  • The 840 Evo doesn't have power protection. Also it isn't even 500mb/s. That too is a result of the "slc" cache on it. It's just an 840 with extreme caching everywhere. If you use it in raid and in a server the cache might wear out fast and it'll degrade back to the slow speeds.

    I am interested in getting 4 of these to run in RAID10 on a Dell SAS 6/iR controller. Does anyone have experience with the Samsung SSDs on these older controllers? The 840s seem to have had some issues with newer Dell controllers (like the H710p) but am not sure about these older generation of controllers...

    We've found SSDs to be so touchy with RAID controllers that it's never worth it to go with something that isn't proven. We even hesitate to use Samsung stuff.

    What about using them with mdadm instead of using the hardware RAID controller?

    Probably lower risk but you give up a ton of performance without the hardware controller with lots of onboard cache.

    Get yourself an LSI 9271 w/ Cachevault and 4 x 480 Intel 520's and you'll be really happy.

  • OliverOliver Member, Host Rep

    It'd be for a Dell server in my case so I have less flexibility with controller models (since the drives would be replacements and not for a new system).

    Overall I imagine the performance will still be significantly better than 7200 or 10000rpm drives and the reduced power consumption is the other significant advantage which I am looking for (more than anything else to be honest).

    I have Intel 520 series in another server in RAID10 on a Dell H710p (LSI 2108 chip I think) and performance is fine.

  • Anyone ended up using this in LSI raid? Just curious.
