Esata to firewire Daisy chain?

[Thomas Morter-laing]

Cool, I just looked…. um my point still seems to stand quite a bit :S Unless Ive missed something, the cheapest thunderbolt drive of any kind is still the LaCie 1TB Little Big Disk… which is £299 (UK Sterling, not sure about US)… so my solution would still be cheaper AND allow 2 eSata connected drives, which despite not being as fast as Thunderbolt would provide me with what Im looking for right now. As well as the other express card connectivity it gives me…. 🙂

Ah sorry Tony- I just saw your second response, ignore my above arguments XD

Cheers Rafael 🙂 OK so Im still getting an adapter 😀

“This whole thing is why many of us are upset about the possibility that Apple is dropping the MacPro.”

Sorry to go off topic…

Just speculation, but if Apple does this, I would not be surprised to see them license Mac OSX to select high end PC workstations. No technical reason why this can’t be done, now that Apple is using Intel.

It allows Apple to abandon creating hardware that is not profitable enough for them, without abandoning a market where their OS has a large presence. A win/win as far as they are concerned. As long as they keep it officially limited to select high end workstations (firmware or some other restriction), it won’t diminish the brand. Hackers will get around it, but they are doing that anyway, as the thriving Hackintosh community already exists.

Would never happen if Steve were still around, but Cook has already stated he is open to doing things differently.

Hope it all works for you. Just an FYI, you do know that to get the Raid capability out of the GRaid, you’ll have to use the sonnet tempo E4P for example vs. the Sonnet tempo E2P. You’ll get 200 mb/sec from the E4P vs. 120 on the E2P. ($300 vs. $50). I use the E2P in my MacPro to drive to eSatas and I’ve been perfectly happy with my decision. If I need more real time I lower the unlimited rt quality and/or frame rate. I drive a G-Raid and a single drive eSata I put together with a chassis and a bare seagate. Both the G-Raid and the Seagate perform exactly the same . Around 120mb. With a FW800 you can get around 80 mb/sec. I’m not sure that it’s worth all the effort of adapters and such to get the boost from 80 to 120 mb/sec if you were to get a basic esata card like the e2p. It was worth $50 bucks for me easily. You say you have 15TB. How much of that can you hook up to the eSata? You can’t daisy chain. So aren’t you looking at only hooking up 2 drives?

Just ran AJA System Test (1080, 10bit, 2gb) on my 2TB 4th gen G-RAID. Here are the results. I included the G-Speed ES drives to establish that drive capacity doesn’t have a substantial difference on speed.

G-RAID FW800 scores:
write 64.7 MB/s
read 57.1 MB/s

G-RAID eSATA scores: (using controller bundled with G-Speed ES series)
write 169.2 MB/s
read 168.3 MB/s

G-Speed ES 12tb RAID-5 scores:
write 158.0 MB/s
read 177.3 MB/s

G-Speed ES 8th RAID-5 scores:
write 158.3 MB/s
read 176.1 MB/s

220Mb/s nanoflash is about 28MB/s. (Megabits versus MegaBytes) You should be able to get two streams of it (56MB/s) over FW800, but for more than two streams look into eSATA or the Promise RAID. They’re saying the 4 drive enclosure gets over 500MB/s – nearly triple your G-RAID over eSATA, and nearing 10x the G-RAID over firewire. Hope this is helpful.

What is the “controller bundled with G-Speed ES series”?
So that supports the idea that if Im doing a reasonably hefty project on this drive, I should get one of these adapters for use with eSata then 🙂

Also, Ive asked this elsewhere on the Cow, but does anyone have any idea whats going on here?:

https://www.scidailynews.com/sonnet-echo-expresscard34-thunderbolt-adapter.html

That one is what I can buy in the UK but it seems to look very different to the one on the Sonnet website :S Any ideas? 😀

I’m running the eSata expander (2) & Sonnet (4) which give 6 ports total.

Unfortunately, this expander i got is NOT hot swappable:

It’s the controller that G-Tech bundles with a G-Speed ES. It has a RAID engine on it, but the G-RAID will always rely on its own internal RAID controller.
