 |
|
Ok, lets see. I'm in the process of copying my
EyeTV captures from one enclosure (OWC)
too the Mediasonic via Firewire 400. The
SuperDuper transfer rate averages 17.76 MegaBytes
a second. Firewire 400 should be 400 megabits a second.
Their are 8 megabits in a Megabyte.
17.76 MB/s × 8 = 142.08 megabits.
Shouldn't the transfer speed be more than
double 142.8 megabits (17.76 MB/s) a second.
I wonder whats up?

It took 27 Hours 19 Minutes & 32 Seconds
to copy 1.75 TB/s via FW400 from the OWC
too the Mediasonic. Thats more like real life
USB 2.0 speed. I'm kind a' disappointed
though for $119 I'm not complaining. If
I had paid $199 I'd probably try to return it.
This enclosure is just a good not a great one
because of its FW only working at USB speed.
EDIT: The OWC turned out to be slow NOT the Mediasonic.

I am just a bit busy this weekend. I have been using the rosewill with my mac pro and it works well. I only ask that you wait a bit for be to do the testing on monday.
rosewill
http://www.newegg.com/Product/Product.aspx?Item=N82E16816132016&Tpk=rosewill%208%20bay
sans digital
http://www.newegg.com/Product/Product.aspx?Item=N82E16816111140&cm_re=sans_digital_8_bay-_-16-111-140-_-Product
basically the same unit. In both cases the jbod should be good in minis with no software or the pci e card. If true these can really turn mini's into a good piece of gear. yeah all drives are maxed at esata speed but 8 drives are 16tb.
if you clone drives;
1 to 5
2 to 6
3 to 7
4 to 8 you get pretty safe storage at good speeds.
the beauty is only 3 wires to do it.
2 esata and 1 power cord. it truly would be a nice solution. all your hopes of raid10 and 5 or 6 all depend on fw800. AS none will work with the esata hack been there done that. Since I purchased the rosewill with my macpro the ability to add 8tb and clone 8 tb is great. I also started rebuilding my mac mini double esata hack. I hope to work on it next week I would do a big write up at this link.

I hope to show a double esata hack with a pair of one bay sans digital towerstors
with a pair of 2bay towerstors and with the 8bay rosewill. |
Hey bro i've been following all your eSata mac mini mods and im reall thrilled if you have got this to work? im in exactly the same spot but i dont have a Mac Pro : ( let me know if that rosewill or any 4+ bay with hardware RAID cases will work with the esata mac mini hack
i have a C2D 2.26 09 model
thaaaaanks!

sad to say no matter what I try I can't get the esata hack to work with the rosewill 8 bay unit.
the best that I can do is have the mini plug into both esata jacks and see 1 hdd for each jack. I also reached a deadend with this unit
http://www.sansdigital.com/towerstor/ts5ct.html
The best I can do is raid0 or raid1 in these two
http://www.sansdigital.com/towerstor/ts2ct.html
can use 3tb hdds giving you a 6tb bootable hdd raid0
http://eshop.macsales.com/owcpages/guardianmax_mini.html
can use 750 scorpio blacks giving you a 1.5gb raid0 bootable
I have not tried this unit it should be good
http://eshop.macsales.com/item/Other%20World%20Computing/MEQMH0GBK/
this would be a nice form factor you could do a raid0 up 1.5tb in two of them they could stack on the mini would give you a mini with 3tb of hdd in a 6.5 by 6.5 by 3.5 inch space. use the 2009 model seems like the best form factor

Awwwww daamm that sucks... i was so sure it would have worked... i dont know why it is not, I think it should have thou right cause it has hard ware raid right? or does it? Oh you know what maybe it dont work cause it requires Port Multiplier (PM). I just checked the specs for both the Rosewill and the Sans digital and they both use PM. I think the minis eSATA port doesn't recognize it. I was checking this one out:
http://www.sansdigital.com/towerraid-plus/tr4utbp.html
And
http://www.sansdigital.com/towerraid/tr5ut.html
let me know what u think bro, I really think its because it requires PM.
Also check out this guy, is the same thing your doing but his using diff cases:
http://www.youtube.com/watch?v=IWtQE96lq40
Same thing but prob your SansDigital cases are better lol.
Heres wat I would love to do:
Sell my 09 mini
Buy 2010 2.4 mini
Do the eSATA hack
Put a 128GB INTEL (like you recommend)
Have a 4 or 5 bay enclosure with 8TB or 10TB for fast access storage.
Use my optical drive on a $10 case that u mention on another post.
Buy the MacBook Air SDrive.
thanks for all your help so far bro.

Ook i see so the mac minis MoBo does use PM because its splits it to two sata ports, the Hdd and SUperDrive.
So ur sayng if i can buy that piece and sawp it and with the ome from the MB then I might be able to use those cases cause im with that piece the sata por is not being multipled?
Honeztly i would buy it right now but i dont the sans digital to test it.
Is there any way I can buy it and have i shipped to u and if possible u can test it?
I think the sans digital cases i pointed u too should work like u said; because i reaserch the IcyBox cases the guy is using in the youtube video amd they're basically the same thing, they dont use PM and they use Hardware Raid.
Also to that part you pointed, from what I see it has only one Sata port only, so i can only hook up one hdd/case/optical drive, or a port multiplier right?

no the part has 1 plug for the mb and two sata slots it is for the 2009 server. the 2009 had two different connection boards. one for the server one for the normal units
https://www.applecomponents.com/items/922-8807_svctransition-board/0000002683?pn=1&cmp=0161&per_page=30
the above is the standard 2009 it is really a dual sata but the one is tiny and goes to the dvd player
https://www.applecomponents.com/items/922-9112_board-interconnect-dual-hard-drive/0000004317?pn=1&cmp=0161&per_page=30
the above has a pair of standard sata jacks
the photos of these parts are stupid they show the backside not the dvd/sata side for the standard or the dual sata side for the server. here is the problem both parts are custom for apple the mother board is custom for apple.
As far as I know there is no custom part that exists .
I tell you what send me a pm with an email I can forward some pictures of my 2 double esata hacks this friday.
One was done on a server 2009 one was done on a standard 2009 . It won't take long to make a few clear photos for you this friday. phil

I'm thinking of getting this one here:
Rocstor Arcticroc 4T Raid Drive
Looks good and appears to be quiet. Actually, I'm probably going to get this version (which seems to be the OEM version) since it's hard to find the Rocstor up here in Canada, except through some obscure musical instrument stores:
DataTale 4-Bay FireWire 800, eSATA, USB RAID Enclosure
I can get it through Amazon.ca for $319.00 CAD (we Canadians always pay more, lol.)
Any thoughts on this unit? |

Ok, since this thread's been revived let me say it wasn't
the Mediasonic that was SLOW it was the OWC. I've since
used both to copy other info and the OWC has been a big
disappointment and the Mediasonic has been a joy.
I have three dual bay OWC enclosures and all have been
SLOW.
I now use the Mediasonic with four 2TB Hitachi HD's
in RAID 10 (1+0) attached via FW400 to store my
EyeTV captures and its worked wonderfully. The
OWC's are collecting dust and I'll end up using them
randomly attached via USB. How sad, the enclosures
are beautiful to look at but just don't perform.
So, if anyone is thinking of a four-bay enclosure
I highly recommend the Mediasonic. The downloadable
instructions could be better though. As far as OWC.
I don't plan on buying any more enclosures from them.
I have invested over $500 into OWC enclosures
and only one works well. Oddly its been the cheapest
(plastic) enclosure thats worked as advertised.

Personatly I've just ordered parts for a low power-consuming Atom based Windows based PC, that I will mainly use as a NAS. Plus, with this setup, I can use it as an emergency PC, if my primary workstation fails. And it can perform nightly backup to my KeepIt account in the cloud.
Plus one for PC based NAS'es  |

You should do a "How To" or a Tutorial on exactly
what you are doing. Start at the assembly and walk
us all the way through to the end as well as why you
are doing it a particular way.
That would be a big help. Many of us are interested in
doing something similar. Will this be your first NAS
project or have you done others? It should be interesting.

I for one would be interested in that. I use a synology nas 1 bay with a 2tb hdd inside. I use it to bridge my 3 macs.
mac mini to nas
imac to nas
mac pro to nas
nas to all three macs
Then the mac pro ends up with everything. That I keep long term.

It looks good. What RAID configurations are you thinking of using?
If you think you may use RAID 10 (1+0) then that enclosure won't do.
If your just interested in the RAID config's it offers then you should be
all right.

Thats a good looking unit, looks like its well built as well. PowerMaxx in Oregon apparently sells these for less then $250, but the status says "call for availability" so not sure if they have them. Might be a new addition to my htpc set up.
