MTRON SSD performance

[samsc]

The MTRON SATA 32GB SSD -

http://www.dvnation.com/nand-flash-ssd.html

can do 11 dv movies at 25 fps with random access playback mode on every layer - not just play loop fwd

max 3147 can only do half this-

Machine tested is 8 core intel 3.0GHz.
Do 8 cores make any difference- NO- 4 reducing 8 core machine to only use 4 CPU's does not change performance.

dv codec is the fastest - performance characteristics are different with photojpeg - photojpeg is cpu limited - not disc.

Does changing the number of cpu's then affect performance of photo-jpeg?

i dont think so.
tests i did with a quad g5 and an 8 core intel using a ram disk ( not ssd ) showed very similar jpeg performance.

gian gets 4 layers from his 'RAID' in his mac pro,.

I get 11 layers from my Solid state disc. with complete random access.

this may sound ridiculous to ask ... but does this mTron fit into MacPros HD internal bays right ?

Just wanna make sure , Cheers

i used a sata power and data cable extender.

these people have one at the bottom of this page

http://www.satacables.com/

part number SS-POW-EXT12 $9.99
it needs to have male sata on one end female the other end.

i made one up from other cables.

i have a 2.5" SSD Sata drive - the same as laptop drives- the sata connections are the same - the physical size of drive might fit with a chassis adaptor. i dont have one.

i have a 2.5" SSD Sata drive -

I saw a 3.5" will that fit in the internal bay ?

i dont know. ask them.
it was more money for 3.5inch version.

Wow, I would love to buy 4 of these per machine and raid them together! It would be awesome!

hybrid drives - with 1GB memory and a hard disc-


The Mcell is an interesting beast. In terms of size, it fits in the standard 3.5" form factor, but inside it actually contains a 2.5" 5400rpm hard drive, a stick of 1GB DDR2 RAM,

tested this inside fw800 in a sata case this week-

works OK not as good as direct sata- but still works well.

8 layers of dv.

pricing seems to have changed- 2.5 and 3.5 inch drives now same price.

What about an external sata connection to an express card for the macbook pro? Will this be able to stream more than 8 dv?

macbook limit is cpu computer performance- not disc.

[litemover]

It definately will work. I have a firmtek EN2st Macbook Pro card for a dual Sata raid array and I can run 2 concurrent layers of 99% photojpeg HD with very little frame loss.

I have the latest and loaded Macbook Pro 2.4ghs Intel 2 Dual Core with an Nvidea 8800 configured for 1920x1200 with 4gb of ram.

It completely blows away my old 2l5 ghz tower with a readeo 850 XT and 4gb of memory apart!

It makes for a great portable system and the only thing I lack is realtime video input.

I assume if I hooked up two of these ramdisks to my card, they would raick.

My 8 core would probably kick arse all over it though as I saw some pretty stunning AECS3 benchmarks at barefeats.com.

I would use it for both if I bought a dual raid. I'm sure it would be fast but I have 15gb in my new 8 core which is siting at my friends house waiting to be used. I'm sure the esperance ramDisk using 10gb of 8 core internal memory might be faster or just ask good with the exception of capacity. I'll run some speed tests when I finally pick it up and post them.

Will there much difference in using a macbookpro 2.33 intel 2 dual core 2Gb ram X1600? I presume i wont because it depends on the acces times of the discs?

[samsc]

mac book pros are limited by cpu and other things not discs.

macbook pro cannot do 8 dv layers whatever disc you use.
cpu/system is not fast enough

Christian

it wont definitely work.
doing 2 layers is much easier.
almost any system will do 2 layers...

but peter asked about 8dv layers.
i couldnt get anywhere near that this week.

Is this using the MOBI 3000 & MSD 6000 Models or the MSP 7000 model?

Does the 3.5" drive only come in the MSP 700 model?

There does not seem to be any difference in performance between the 'old' and 'new' models.

All work well.

You are wasting the performance of the computer by not using these!!

sata drive technology is years out of date, and has not increased real world random access performance for years.

I have been looking to replace our 146GB 15000rpm SCSI drive with these SSD's. But to get the same capacity i would need two 64GB versions, what is the recommended way or running these. Leave them as two separate drives/libraries or join them as a software raid for one volume. My gut feeling is the first as it won't cause you to loose the whole disk of one fails. What are peoples opinions?

Also are you going for the 3000 or 6000 series, i believe the 6000 is slightly faster. Is it worth the extra expense for the 20mb/s?

Cheers

Suggest buying big normal SATA drive - keeping everything on that disc - transfer over content needed for immediate show.
you can playback from sata and mtron at the same time

no difference i ever saw between 6000 and 7000 series. i dont think its worth the difference in pricing right now.

no need to raid anything - leave them separate - no difference- unless you are planning on uncompressed HD...

[gazzer82]

Thanks richard, that all makes sense. No plans for uncompresses HD in the near future. It's most SXGA+ stuff at the moment, all compresses using AAC or JPEG depending on the content, we are mostly using the Panasonic 7700 and PTD-10000U.

Hey Gareth,

Be careful not to think "uncompressed." PhotoJPG at 80% on a media server is about the best you will ever need for anything. As for large files, Apple Intermediate Codec is almost perfect for live projection.

If you need more than 64Gb, one suggestion is to get one of the 2.5" laptop Mtron drives. The currently have a 128Gb at dvnation.com which works fine. If you need for it to fit in your mac pro, there are tons of places you can find online to buy a 3.5" housing that receives a 2.5".

At least that way you won't have to wait until the 128Gb comes out in the 3.5" size.
