  3. Do I need SSD drives?

    Hello Christan

    The faulty is either MAC OS X or either VSL software, it will be great if you could write this little programm that loads 10 ot 15 GB in memory so we see how MAC OS X reacts

    The raid card is a Rocketraid 640 sold by Apple in the US and my SSD are from Crucial, 

    If I use my ssd raid for other task and it is performing very fast ! not at 3.30 MB/s

    The graphic is DISK I/O not CPU usage

    My VM is on a separate disk 

    I have put you at www.cyrilblanc/vsl1.png to vsl11.png all the result of BigTop

    There is another user that have report that the new version is slower too http://community.vsl.co.at/forums/p/27428/179771.aspx#179771

    what do you think of this idea :

    Just  an idea :

    You load a VE PRO in a VE PRO server, pause this VE PRO

    Load all the VE PRO

    Then you start all the VE PRO.

    Best

    Cyril

    P.S. How do I return to previous version ?

    Test done with a raid 0 of 6 raptor  and normal disks show exactly the same, fast load to start then it slow down

    Best

    This is a very interesting thread for computer nerds like myself :).  I can't wait to see what ultimately is the problem.

    I'm going to build a new computer around an I7 950 with a RME 9632. I've been reading about SSD drives but I'm not sure I would get any appreciable performance increase from them. I will be using VSL SE +, Spectrasonics, Symphonic Choirs and selected samples in Kontakt 4. I can afford them but do I need them?

    According to tests done on other forums, there is an appreciable difference in performance using SSD when using Windows as your OS. Not only is the loading time faster, but the pre-load buffer for Kontakt can be reduced, which  not only reduces the RAM footprint, but also reduces loading time still further. You should also be able to get increased polyphony from the drives.

    However, it all depends on your workflow whether or not this has any real point. For me the faster loading times would make very little difference, as I only load the computer once a day. However, if you like to swap templates often, then the faster loading time will certainly be noticed.

    Just recently upgraded the boot and program partitions to SSD.

    Even without Win7 & Advanced Host Controller Mode the difference is huge.

    Vienna Instruments & Cubase just "pop" out instead of the HD cantiliver scratching around, killing time.

    Same of course is true for general system performance ( bootup time and "feeling under the mouse button"). That alone is worth the price.

    Sample libraries on SSDs maybe a different story. I think they are extremely strong in random read. For pure data transfer ( and that´s what happens when you have to load >1GB of samples in one row) I´m not sure if they are superior to conventional HDS.

    Against regular discs I think they still opearte faster.

    But regarding some of the system specs of Vienna users here ( i7 extreme...6 Velociraptors in Raid 0 [:)] I don´t want to bet on it

    I just had contact with vsl support concerning my problem, that during tutti passages in my 8 Minutes romantic orchestral piece, the VI-64bit plugin of my Cubase 5 64bit host needs more speed to grab the data from 5400 rpm Harddisk. There ist two parameters, I guess, which have to be considered important. One: the transfer rate speed and two: the access speed (which is important for grabbing small chunks of data spread over the storage media. I think that the access speed (german: Zugriffszeit) is the factor to keep in consideration. But I'm not a specialist in such things. cheers,

     5400 is just too slow for sample streaming. Use 7200 and all will be well.

    average seektime is often the problem (the time the heads need to get positioned over the right sector of the disk).

    usual values for 7.200 rpm disks are around 9 ms, WD raptors ca. 4.5 ms, velocity raptor 4.2 ms, SSDs < 0.1 ms, 5400 rpm disks around 15 ms

    and remember: only a CRAY can run an endless loop in just three seconds.

    Well I don't think so. I just put in a 7200 rpm 2,5 HDD and it didn't work. Same problem. Are there other solutions? Selling my notebook and by a Desktop, just because the VSL philosophy depends on smallest access times which can only be achieved with 3,5 7200 rpm drives or SSD Drives? Wow that's hard stuff. My notebook is just 4 months old. Nobody not even the VSL support told me that it is impossible to operate a large orchestra with a notebook, which is brand new and has a powerfull provessor. It's access time stupid. That's what I'm going to tell my image in the mirror before getting mad.

    hmmm, i can't believe a somehow modern notebook with a 7.200 drive cannot handle SE and even a little bit more ... is there anything else eventually preventing throughput (you don't record = write simultaneously to the disk, do you?), what about your soundcard (ASIO settings)?

    paul often does clinics with full orchestra arrangements on his macBook PRO (which was *only* some core 2 duo model ...)

    I think it is dependent on what you call "large" orchestra.

    Did you connect the new 7200rpm harddics internally or do you still use an external USB2.0 case ?

    I think USB 2.0 will be more a bottleneck than the 7200rpm, although as mentioned before, access time is also an important factor.

    But the most important point is how many instruments you gonna play at once, maybe there also is something additional going on with other softsynths, samplers etc.

    Also : What audiointerface do you use ? There can be large differences in CPU and overhead demand between the models. If you get clicks and dropouts, try using a larger latency.

    IMO you should be able to basically make music with an i5 laptop and a fast conventional HD using the Special Edition.

    But hey, there are people here on the forum discussing about 3x Raid0 WD Velociraptors or multiple SSDs. It really depends on what you want to do.

    Of course I installed the HDD drive within the Notebook. The usb 2.0 interface only brings it to 35 MB/s because although theoretically it should be 60 MB/s with HI-speed, the USB 2.0 protocol has in contrast to Firewire 400 a much too big security overlay redundancy. I wrote USB 2.0 in my setting because there is already usb 3.0 and eSATA available for notebooks, which might help me out now. Within one year usb 2.0 will be what is now usb 1.1. It might be possible that an Apple chipset will be 2 or 3 MB/s more effective but the problem here is not the chipset but the usb 2.0 protocol. What's the hardware recommendation of the people of VSL? For a flute, for a violin and a clarinet and for big orchestra?
