  3. 4 Samsung 1 Tb SSD an RAID 0

  • 4 Samsung 1 Tb SSD an RAID 0

    Hi,

    I just purchased( 4 )1 Tb Samsung SSD for my sample library. I'm currently using a 2010 Mac Pro 2.66 gHz 12 core as a slave, with 48 gigs of RAM, Areca 1213-4i with 4 Velociraptors in a RAID 0 configuration and I'm getting around 500 mg/sec read and write in. I'll be replacing then with the Samsung 1 Tb ssd and I've been reading that it's better to spread your samples across al drives instead of using RAID 0. I'm also insataling a NewerTeck Max 6g SAS x 2 using my 4 Velociraptors as external drives for samples that don't require fast drives. I'm aware of the issue with RAID 0 if a drive fails but I have a back up all my libraries. I would like to know if I'm better off using a RAID 0 or spread my library on different drives? Thanks

    Do you have a trash can Macpro ?

    If not it is a non sence to put 4 x ssd in a Macpro that has a SATA II bus, you should get a SATA III Rocket Raid card

    Thank for your response! I thought the Areca 1213-4i has the same performance. I also installed a MaxPower 6G card  with x2 external  SAS outin it because I'm using my 4 Velociraptors for the libraries that don't need the speed. I should compare the Rocket Raid card with my Areca 1213-4i. I tried testing the performance of a single SSD compare to the RAID and I'm getting a slight increase which kind of shockesd me.

    I'm aware of the SATA II limitation on my 2010 Mac Pro and that's why I purchased the Areca 1213-4i

    I forgot to answer you question. I have a 2010 Mac Pro 12 core

    I had a look to the spec of your Areca, it does not says that it is a SATA III

    With a Raid 0 of 4 x ssd you should go over the 1 GB/s

     

    Run BlackMagic disk speed test on your different SSD/HD and give me your results

    Why dont you want to run the Blackmagic test, it's free

    I did and I got similar results. with the Areca 1213-4i I got 1275 write and 1157.8 read. I also installed a MAXpower RAID mini-SAS 6G-2e using the 4 velociraptors in an external enclosure and using Blackmagic test write speeds were 459 and read speeds 482. Just for testing purpuses I also plugged an enclosure with 4 1 Tb WD black with 64 MB cache and write speed was 267 and read 289. The MAXpower performed very closed to the Areca and the MAXpower is a 6g PCIe card.

    I opened up "about this Mac" and went to the systems report and checked the PCIcards and it was reporting that both cards are running at 5gb/sec. I don't know if this is accurate.

    My main goal is to see if I can get better performance with the SSD running them at RAID 0 or separate which I got similar results just a bit slower. Does that mean that if I'm running the SSD as none RAID, it would get a total of let say 1200 x 4?

    With what ? 1 x SSD ? 4 x SSD in Raid 0

    > I also installed a MAXpower RAID mini-SAS 6G-2e using the 4 velociraptors in an external enclosure and using Blackmagic test write speeds were 459 and read speeds 482.

    This is a normal figure, are the 4 HD in Raid 0

    With what ?

    I dont understant you can get 1200 MB/S with one SSD, which model ?

    The figure I get :

    SSD M4  w = 233 MB/s r = 242 MB/s

    Raid of 2 x SSD Samsung  w = 793 MB/s  r = 893 MB/s

     

    What is said about  Raid 0, is you multiply by 1.5 for each disk

    Sorry I wasn't clear, I was in a hurry because I was transfering files and upgrading my studio. My apologies

    Here's the result with x bench with 1 Samsung 850 evo SSD with the Arec 1213-4i

    I didn't get a chance to use Blackmagic test, but perhaps I'm not familiar with xbech so perhaps you can clarify the performance of the Samsung 850 EVO 1tb. This results are from another one from the 4 Samsung 850 EVO since I trashed the rest and luckily I had this one left. I think I read the wrong numbers. But the results I gave you which you qouted was usin Blackmagic, except for the single SSD result.

    I use 4 drive per RAID 0. The Areca 1213-4i handles 4 1TB Samsung 850 evo installed internally on my 2010 Mac Pro 2.66gHz 12 core with 48 gigs of RAM

    I have the MaxPower RAID mini SAS 6G-2 installed on the same MacPro and I'm using 1 external enclosure with 4 600gig Velociraptors 6g and another enclosure with 4 WD 1Tb drives 6g both RAID 0                                                    I got the same performance with both RAID cards with the Velociraptors set up as RAID 0 which was 459 mb/sec write and 482 mb/sec on read.

    What I decided to do is use the SSD 4 tb RAID for Hollywood Orchestra, EWSO platinum, VI cube with some upgrades dimension Brass. The External RAID with the Velociraptor for my Kontakt samples which includes other Orchestral samples, Heavyocity stuff and the other RAID enclosure with the WD Black HD for Spectrasonics stuff and misc libraries.

    Sorry for the confusion, it's hard to find performance benchmarks with a specific RAID PCIe card using the SSD or HD I'm using, so I though I would post it to help out. But aparently the Areca 1213-4i could be 6G since I got similar performance with the Velociraptors which are also 6G drives.

     The reason I got those PCIe RAID card is because it's supposed to break from the 3g limitations with the Mac Pro. I was barely getting 100 mb/sec with a eSATAIII card and 4 WD Blacks in a RAID 0 configuration in an external enclosure!

    You cannot compare Xbench and Blackmagic !

    I've always used Blackmagic. But before I decided to post some questions, I've already had the SSD's in RAID 0. I also transfered a bunch of libraries so I didn't want to undo it and start ove. I couldn't remember what I got with the single SSD using Blackmagic. I got Xbench because I wanted to try something different and when quitting xbench it kind off forces you to save the results so that's all I had! I was able to give the results with the blackmagic because I did it later after my confusing post. English is my 2nd language and Spanish is my first so my apologies for the confusion.

    I am French !

    if with Blackmagic you get 1 200 Mb/s with your 4 x ssd in Raid 0, this is good and normal

    Using a Sata III card with HD or a raid of HD, it is like giving jam to pigs 😉 you better put SSD 😉

    Lol! Weel your English is way better than mine! That's why I'm using the 4 Samsung EVO 850 1Tb SSD as RAID 0 for VSL cube and Hollywood Orchestra and the 4  Velociraptors RAID 0 for other sample libraries that don't require the speed of the SSD. The Areca 1213-4i was a pain to set up(at least for me) so If 1200 mb/sec is normal thae I guees I did right!

    I can't find that many benchmarks with 4 SSD with specific RAID cards.And the companies of these RAID cards only give you a theoretical speeds only. Thanks Cyril! ( what a cool name!)

    How is it beneficial to have 4 SSDs in RAID 0 rather than distributing samples on 4 separately SSDs?

    If you go to EW forum, there's many discussions about using 4 separate SSD and distributing the samples into the 4 differenttimes, but nobody gives you any real live test results as far as comparing it to  RAID 0.

    You move from around 500 MB/s to 1200 MB/s, you should be able to reduce pre-load buffer size, loading much more samples in memory

    VSL loads samples sequencialy
