Does daisy-chaining a Belkin Mac-compatible hub affect performance?

I've had a 7-port Belkin hub plugged into my 13" Macbook and before that a 15" Powerbook for several years and have been pretty satisfied with it. I'd like to get a new one and connect it to the original (or vice-versa). Does anyone know if doing that would affect performance of any kind? (Upload times, wireless mouse interference, etc.?) Belkin doesn't seem to have anyone who knows much--the rep I talked to didn't even know Belkin made a hub that works with Mac.
Thanks for any information anyone has.

That makes sense. My old hub is 2.0, so it should work with the new one I want, which is also 2.0.
I don't know how much power I might ever be using at one time. have a wired keyboard and wireless or USB mice, and at times I probably download something into my printer buffer while at the same time backing up to an external hard drive or flash stick. But I don't think I'd ever be doing more than that, and the present 7-port hub seems to have no problem handling jobs requiring 4 ports at once.
I really just wanted the second hub because the present one is at the back of the desk behind the dictionary (cord is too short to reach the front!), and I'm tired of trying to insert devices into the USB ports without knocking the dictionary off its stand. I figured that plugging a second 7-port hub into the first one would allow me to have a hub at the front of the desk and give me a few extra ports as a bonus. If you have a better idea, I'd be happy to hear it! Meanwhile, thanks so much for the information, and the fast response.

How many firewire drives can I daisy chain on the mac mini

How many firewire g-drives can I daisy chain on my mac mini

From personal experience, if they are bus powered portable drives,
the answer is none. For what ever reason, they are draw a lot of
power and are probably near the edge of the bus powering specs.
Then again, these were the fastest of all the portable FW drives that
I have (Iomega and Seagate being the others), which may have
something to do with it.
I had also noticed an issue with them even with USB. Plugging one
into the Mini or even a powered USB hub would be fine, but 2 would cause
both to be inaccessible, unless I used a couple of USB "Y" cables
that would distribute the power across other ports.
If they are externally powered, you could string a bunch.

Daisy chain 2 monitors Mac Mini

Hello,
Im currently running a Mac Mini (Late 2014). I'm currently using 2, Dell S2240M monitors, but am in the market for new displays. Currently I have each monitor connected to their own individual thunderbolt port using a thunderbolt to VGA adaptor (as the monitors themselves only support VGA & DVI-D connections). In my research I've come across others dasiychaining monitors together through a single Thunderbolt port, connecting the first monitor to the second via another Thunderbolt cable. Does anyone know the requirements to do this? Am I able to do just as well using DVI-D /VGA to receive the same outcome? Does anyone have another workaround for doing this?
Ultimately I would rather not pay a thousand dollars twice for two Thunderbolt displays so as you can imagine, Im open to trying other workarounds if anyone has one.

That daisy-chaining only works with Thunderbolt monitors and App is the only one making them.
The Thunderbolt port on a Mac, except with a Thunderbolt monitor, uses the Mac's Thunderbolt port as a mini displayport and that does not support daisy-chaining

Does daisy chaining Firewire 800 drives reduce performance?

Hello,
Based on the recommendation of a very knowledgable Apple Cert. Instructor, I learnt that a very good drive configuration for editing in FCPX is to have 3 separate drives: Boot disk, Events, and Projects. The reason, I suppose, for having the Events and Projects folders on separate drives is because FCPX is constanty reading and writing data into those 2 databases, which would mean that having both databases on one drive strains performance since the drive would have to write all edit changes constantly in the projects folder while reading video footage constantly from the events folder.
That sounds logical so I'll accept it as being true, but here's the intro to my question: I have an iMac (see the specs below) with 1 firewire 800 port, and my extra 2 drives would need to be daisy chained (FW800) to share the 1 port.
1. Does the communication to the two drives suffer for being daisy chained into 1 port, i.e. is the 800Mb/s transfer rate halved between the 2 drives or is full 800 to both at the same time?
2. Does the computer handle the communication with the 2 FW drives via that 1 port evenly so that I takes full advantage of having separate physical disks dedicated to just reading and writing Media and Project data?
It might seem riduculous to go to such Media Management extremes, but FCPX seems to struggle when I get deep into a project and the performance gets sluggish. that's why I'm trying to optimize the workflow.
Thank you,

If all the devices in the chain are FW800 then there will be no degradation.
If any of the devices in the chain are FW400 then complete chain drops to FW400 performance.

Does daisy chained firewires make performance drop?

Hi all, just looking for a quick answer by someone who knows what they're talking about. Will daisy chaining firewire 400 drives together on a Mac or PC create a performance drop? I'm editing a project using 2 daisy chained drives at the moment with media on both. My co-worker claims it will slow down the computer's access to the media, I say it won't. Neither of us has any hard evidence and a quick google search doesn't turn up anything substantial either. What I'm looking for is hard engineering evidence. Thanks!

The firewire protocol allows for 63 or so devices to be chained together.
Running two FW400 devices should not be an issue. I've run up to a eight on chain in the past.
Still, be aware that some drives do not play well with other drives on the same chain. I have a G-RAID 500GB drive that tanks when there is another drive connected. It runs fine when it is the only drive on the bus.
If you are curious, go to the AJA website and find the "AJA System Test" app. It is a disk drive throughput test. Connect your drives in various configurations and see what happens.
Good luck,

Does daisy chaining affect assessment results?

I need to break a large Captivate 4 project file into smaller segments. If I daisy chain the resulting segments, what will happen to the assessment results from the first one or two segments. Currently, assessment results from all slides appear as a cumulative total after the quiz at the end of the tutorial. If I split the tutorial and daisy chain the segments, will the total assessment results still include assessment results from all slides in the daisy chain?
And what happens to the table of contents? Will every segment of the daisy chain have the same table of contents? If so, how would I update the table of contents if I needed to?

If you daisy chain a project then each of the projects will be a separate instance with no communication between them. Basically all assesments, TOC etc will only apply to that particular project so you wont be able to get a cummulative total for your assesments in the last chapter.
If you have access to a Flash programmer you could create functionality to store the quiz results from each chapter and then bring them all together in the last chapter.
As for the TOC there is no joy. Perhaps you could use the Aggregator function instead but the functionality and level of detail is not the same as with the TOC.

Why does daisy-chaining a Mini-DisplayPort monitor in a Thunderbolt chain cause overscan issues?

I have the awkward 2011 MacBook Pro with a single Thunderbolt port and no USB3. I very frequently use it connected to my HP 2311x LED Monitor. For the very first time, today I placed a external Thunderbolt drive in-between my MacBook Pro and the HP 2311x. This causes the image to severely overscan. Correcting it by using the underscan option in the display settings significantly reduces image quality.

Two more of interest:
http://support.apple.com/kb/PH11407
http://support.apple.com/kb/PH11409 which also says if a device works properly by itself, but then not correctly after the TB device, there may be a problem with the TB device.

Firewire daisy-chain trouble with Leopard. Will a hub help?

I cannot get reliable daisy-chaining of my external Firewire drives under Leopard. A Firewire drive directly attached to computer will work, but subsequent daisy-chains to this drive will not mount more than half the time. I ended up getting corruption of 2 drives: there appears to sometimes be Spotlight crashes/Finder crashes, and Disk Utility repair failure after a mount fails.
I have nine FW drives, and I like to keep bootable clones of all 3 of my Macs with the current system and a couple of generations back. Being able to attach only one drive to my 12" G4 Powerbook 1.5GHz makes cloning difficult (I can only clone the internal drive using my Powerbook). If I get a Firewire hub, will my FW connection then be reliable? There seems to be a problem in Leopard as I don't get daisy-chain problems using the same drives under Tiger. The drive activity lights don't even flash when the daisy-chained drive mounts fail under Leopard, so it appears that Leopard is making no attempt to mount the drives. Why would this be? Yet sometimes daisy-chain drives have mounted just fine.
Makes/models I have tried: Smartdisk Firelite (were sold by Apple), Maxtor OneTouch III, Seagate FreeAgent Pro, and Iomega Black series. I tried various cables.
Does anyone know what the difference is, from a hardware standpoint, between daisy-chain vs. using a Firewire hub. Would there be an inherent difference using a hub?
Are the "hubs" with Mac Mini footprints actually true hubs or are they daisy-chains? How about FW drives with built-in FW "hubs": are THEY actually a true hub or a daisy-chain in disguise? (Sorry if these questions seem stupid.) Recommendations for a hub?

Sorry just noticed I've probably posted this under the wrong forum header

FireWire 800 Daisy Chain Problem

Hello everyone, I have three firewire drives. Two 2TB 3.5" drives and one 2.5" 1TB drive. All three are connected to my MacBook Pro 13" via the one firewire port in a daisy chain. I usually always have the 3.5" disk connected. When I add the portable drive to the daisy chain, it crashes the desktop drive, and I get the "do not disconnect drives without ejecting" message. Is this normal? I am thinking of purchasing the Thunderbolt to Firewire 800 adapter, only to avoid the crashes of the other drives in the Daisy chain.
My Mac is an early 2011 13" MacBook Pro i5 2.3GHz with 16GB RAM.
Thank you for your help in advance

Sorry for my late answer.
The disc has 2 FW800 and 1 USB2.
If you buy a TB to FW800 you should give to the disc more power from the TB port.
If you connect the disc with USB you could use a special cable with 2 plugs on one side and one smal USB plug on the other. This cable is designed to give to one disc the pover grom 2 USB ports but one of the 2 can also be connected to an USB power supply, so ytou will give to the disc more power.... of copurse with USB you have a lower speed.
If you have Thunderbolt you should try to use TB discs. I know they are expensive but there is a trick which I like to use... have a look here http://www.youtube.com/watch?v=1Aa3BXmQVpc

Mac-compatible plug-in for feathered-wipe video transitions?

Does anyone know of a Mac-compatible alternative for SpiceMaster for creating feathered wipe video transitions? I've just been handed off a job (let's just say the company who started it is "no longer in the picture") and all they used feathered wipe via the SpiceMaster plug-in about 100-150 times (in a 15 minute video — sigh). Anyways, I can't change the visual direction of the project, I just have to clean up the mess. We're Mac-only and the SpiceMaster plug-in isn't available on the Mac.
While one option is to use a liner wipe Video Effect (which allows for the feather), because of the amount of transitions in this job, that's not only a major pain in the arse in itself, but having to move clips in alternating tracks and overlap the footage, etc. becomes a huge headache when they decide to change the edit (as, all of a sudden, the alternating of the clips to different tracks goes all out of wack).
Anyway, I'm hoping someone could suggest a Video Transition plug-in that would allow me to do feathered wipes. It'd mean the difference between a quick replacing of the SpiceMaster transition with whatever plug-in I could use vs. a nightmare of a project using the linear wipe Video Effect.
Any suggestions would be most appreciated!!!
Kristin.

Thanks for the reply. I've tried using the gradient wipe, but was unsuccessful in attaining the desired effect. Here's a quick screencap to show what I'm seeing:
The problem is, this results in a very narrow wipe. I mean, it's no longer a fine line between image1 and image2, there is some feather, but I really need to feather it out. The gradient I created is the same dimensions as the sequence I'm working in, and is a gradient from 100% black on the left side to pure white on the right, with a nice gradient in between. But, when I use this, it's almost like the source gradient is squished in (on the width) resulting in a very narrow feathered wipe.
Below is an example of the rendered video as it was when using SpiceMaster to create the feathered wipe. The first image is the image directly before the wipe starts, the second image the image directly after the end of the wipe, and the third image is a capture mid-wipe. As you can see, there is a very wide feather during the transition as opposed to what is seen in the screen capture above.
Am I doing something wrong when creating my custom gradient? It seems like, since my source file is a nice, wide gradient, it should result in a wide feather, but for some reason it seems to squish down into a narrow feather?
Any suggestions?
Regards,
Kristin.

I have a Mac Pro tower with two internal Hard Discs, each one 2TB. I purchased a 3TB Time Capsule. But it does not allow me to back up because it says there is not enough back up space available. Between the two HDs there are 3.3TBs. Can I daisy chain TC?

I have a Mac Pro tower (OSX version 10.6.3) with two internal Hard Drives, each one 2TB.
I purchased a 3TB Time Capsule. But cannot back up because it tells me there is not enough space.
I have more than 3Tbs to store to the new TC.
Can I daisy chain two TCs to store the 4TBs?
How can I back up only the internal HD that is already full, without backing up the other one?
How can I do back up using Time Machine to back up the 3.5Tbs?
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?

Can I daisy chain two TCs to store the 4TBs?
No, you cannot link to produce a single large partition.
But you can have two separate backup jobs.. and use each partition. That is hard on TM but you can easily get a different backup software for it.
How can I back up only the internal HD that is already full, without backing up the other one?
In TM you do a different setup and exclude the other drive.
But it is better to use an alternative software IMHO.
How can I do back up using Time Machine to back up the 3.5Tbs?
You would need to use a network drive of more than 4TB .. it would also take forever. This is just wrong way to do it. Although you can buy a NAS that will work with Time Machine and load it with disks 16TB is possible.. if you can get a second mortgage.. the fragile nature of TM on 3rd party devices.. would leave me in cold sweat if anything went wrong.
TM is excellent at keeping incremental backups of files that keep changing.. as such you should use TM to backup your OS disk and main user directory.. exclude all files and directories that never change. Back them up separately.
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?
Yes, that is a much better idea. You want to store photos safely and you want to store them in multiple places. If you have multiple TB of photos, dedicate a couple of disks to the backup. ie have at least two copies.. not in backup format.. in straight copy format if possible.. so you can keep one of the disks offsite.
I would be using your MacPro internal disk access, to place the disk onto sata bus and do the copy disk to disk direct. Or even buy esata card.. or sata to esata converter cable so you can use esata box. That will beat any other transfer speed except thunderbolt for which you would need third mortgage. (The MORT in mortgage is significant).
The great jurist Sir Edward Coke, who lived from 1552 to 1634, has explained why the term mortgage comes from the Old French words mort, "dead," and gage, "pledge." It seemed to him that it had to do with the doubtfulness of whether or not the mortgagor will pay the debt.

Daisy chain two display port monitors (Dell U2913WM) to new Mac mini Thunderbolt?

Everything I read said that I could hook up a display port monitor to a Thunderbolt port on the mac mini. I purchased two display port monitors (Dell U2913WM) that can be daisy chained, and hooked them up. All I get is mirroring. Does anyone know how to turn off mirroring with this setup? I did not get the "uncheck mirroring" option in preferences until I hooked up the second via the HDMI port instead of a daisy chain. The problem with that is, I cannot take advantage of the full resolution through the HDMI. It seems I have wasted my money on two monitors.
Looking for advice on:
1) How to daisy chain these two Dell monitors to the mac mini and turn off mirroring and use an extended desktop, or
2) How to take advantage of the full resolution through HDMI port?
Any help would be greatly appreciated.
Thanks!

So re-reading this thread, I now realize you did exactly what I wanted to do but your issue was having a cloned vs. extended desktop. Oops!
I believe your "nothing plugged in" issue is the cable. I'm not sure that TB cables are backwards compatible with DP - I think it's only the ports. Do you see multiple monitors in "System Preferences > Displays" if you hook the monitors up like you described in your OP?
My Dell U2713H arrived today and it works like a charm with the supplied Mini-DP to DP cable. The built-in display on my 13" mid 2009 MBP still works if not in clamshell mode, although I will mostly use mine in my HengeDock. In the OSD of the monitor, you can access "Display Settings > Display Info" and it will show you the DP capability. Mine is only DP 1.1a and I believe to run 2 of these at full resolution you will need the bandwidth in DP 1.2 which includes MST (daisy-chaining). This could be your problem.
Can you access the same menu in your OSD and report back what your DP compatability is?
Thanks!

Can I daisy chain a DisplayPort-only monitor through the 2nd TB connector on a WD 8TB My Book Thunderbolt Duo to a mid-2011 Mac Mini?

I'm very tempted by a refurb HP Smartbuy ZR2740w 27" WQHD display, but it doesn't have a HDMI port. It does have DisplayPort.
Since the mid-2011 Mac Mini I have has either HDMI or Thunderbolt to choose from, plus I've just bought an external TB storage system, I think I'd need to connect the monitor to the second TB port on the external TB storage and hope that the external storage would pass the DisplayPort signals along.
I've read that DisplayPort connections are compatible with TB ports on Macs, and that you can daisy chain TB devices.
I don't want to assume those statements hold when I'd need to connect the DisplayPort cable to the 2nd TB port on the external storage.
Anyone know if this will work?
Is it "supported"?
Thanks!
Andrew

23. How do I connect my Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to my Thunderbolt-equipped Mac when I have other Thunderbolt devices connected?
When connecting a Mini DisplayPort display or a display using a Mini DisplayPort adapter to a Thunderbolt peripheral (except as described in question 24), make sure the display is connected at the end of the Thunderbolt chain. You can use only one Mini DisplayPort device in the Thunderbolt chain.
Note: Systems with more than one Thunderbolt port, like an iMac, can have more than one Mini DisplayPort monitor or monitor connected with a Mini DisplayPort adapter connected as each Thunderbolt port can support one Mini DisplayPort display.
24. Can I connect my Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to my Apple Thunderbolt Display?
Mini DisplayPort Monitors or Monitors connecting with Mini DisplayPort adapters will not function when connected through a Thunderbolt Display. They must be connected directly to the Thunderbolt port on the computer or to a non-display device as indicated above.

Mac Mini 2012 (new) - displayport daisy chaining.

Does anybody know whether the TB controller on the 2012 (new) Mac Mini supports DisplayPort v1.2 daisy chaining? I am aware of the limitations of the current Apple TB display, but am wondering if a workaround would be to use display v1.2 panels. My guess is that the TB controller used in the TB display was not compatible with multiple display handling (e.g., Eagle Ridge), but was hoping that the controller used on the macbook/mac mini/imac logic boards does (e.g., Light Ridge). HDMI is too limiting, so I was hoping to daisy chain 2-3 displayport v1.2 displays off of the single TB out from the new mac mini.

thanks the replies. OWC sold me the kit, cable etc based on the Macmini's specs. I talked with support and the drive I installed should work with no issues.
They did have me reset the PRAM which did. They also told me I might need to install Yosemite 'several times before is sticks' - whatever that means. lol.
Anyway I zapped the PRAM. So far no mysterious restarts with the drive being unrecognized.
One thing I didn't mention though...
MacMini is in a backyard home office (about a 100 feet away with buried CAT6 cable connecting it to the network). I was using Screen Share from my MBP reinstall all my work software. Every crash occurred while using screenshare. I never had any crashes when I was actually sitting at the computer.
I don't know if that has anything to do with it - but I haven't used ScreenShare for any length of time to control the Mac mini since the pram zap. Figured I'll use the computer for a week or so and see how stable it is and then try using screenshare again and see if the behavior repeats itself.
Meanwhile I'll keep my fingers crossed.
I'm just suspect that it was a PRAM issue. But I'm a layman.

Thunderbolt hub with dvi-d dual-link, daisy chain that isn't too expensive?

I've been following a number of thunderbolt hub progress for 2 years now, and STILL can't find one that I need.
UTTERLY MUST HAVE dual dvi. This means a minimum resolution of 2560x1440, which is what my current 27" IPS monitor does.
UTTERLY MUST HAVE gigabit ethernet. Wireless N does not cut it.
Really nice to have a daisy chain so I can hook it to my thunderbolt external drive, but not critical.
NICE TO HAVE a power out so I can power my MBA from it, e.g. have two cords - thunderbolt + power, so I don't have to carry a spare power adaptor to the office.
Basically what I've been seeing is either DVI single, or hdmi, or no daisy chain, or no video at all.
Here's things I've looked at that DON'T cut it:

http://www.belkin.com/us/support-article?rnId=8415
http://www.caldigit.com/thunderboltstation/index-ee.html
Oh, and just to pre-empt the guy who who inevitably suggest that I just buy a new apple display (as if they are worth throwaway money): NOT AN AFFORDABLE SOLUTION, please just move on.

I don't believe that a product exists that meets all your requirements, though it's possible I've missed something. Probably the only way you'd get even the primary two requirements is to get an expansion chassis and add the appropriate PCI cards, and that's not going to be cheap.
