Thunderbolt RAID vs USB 3.0 RAID

With a 5 sata drive 10TB RAID, is Thunderbolt RAID much faster than USB 3.0? With the drives being sata anyway? can they take advantage of the speed difference between USB3.0 and Thundebolt?

Barefeats answered some of that. So too did t he large Anandatech review.
USB3 is crippled by all the USB3 ports sharing a single bus controller it seems and is worse in performance than on say a 2013 MacBook Pro.
You need to go Thunderbolt/Thunderbolt2 if you want something more than just a consumer level storage, maybe okay if there is only one USB3 storage device used at any given time, might work for JBOD.
You could also look into ethernet and NAS interface. Someone wanted to use an array with an old and new Mac Pro where NAS would probably work best even perfect solution.

Apple Xserver Raid, 1 raid mounts and the other raid does not mount

Apple Xserver Raid, 1 raid mounts and the other raid does not mount but all the lights on the drives are green

Kind of lacking in detail there...
Did the other volume mount in the past? and it stopped working? When? What changed?
What does Raid Admin.app have to say about it?
Does it see the drives? a RAID set on those drives? A link on the fiber channel connection?

Thunderbolt display speaker USB output not selectable

Hi There,
My thunderbolt display was working perfect before I upgraded to Mountain Lion.
Now I found it doesn't let me select ThunderBolt display speaker USB output.
it will jump to internal speaker right away once I select USB output.
I had ensured no any other USB connected to my MacBook Pro.
I am very sorry that the Chinese Snapshot attachment, but you can easily guess what the item is.
My Macbook pro is 2011 made, with 2 GHz Core i7, 16GB 1333 DDR3, now OS is 10.8.4,

Don't feel bad. You are certainly not the first person to make that mistake and it is equally certain you will not be the last.

Mac Mini with RAID - 4x USB Drives

I've got an older Mac mini 2007 Core 2 Duo machine that isn't doing much since I got the MacBook so I thought about using it to replace my Windows Server.
I did want to have some form of redundancy attached to this server so I hoped to use 4 USB drives of 4tb capacity. I hoped to use two drives "doubled up" to get the capacity I needed (8tb) and another two to "mirror" the first two for redundancy.
I'm aware that OSX has RAID partitioning available but wondered if what I want to do is possible, has anyone tried this setup?

Thanks both for your thoughts.
I'm now having a rethink myself as USB2 does have limitations I want to avoid, and have come up with options:
A new Mac mini with USB3/Thunderbolt to speed up the throughput (I will be using it to stream HD to Apple TV, for the iPhoto Library and for Time Machine Backups) on which I would use either a Direct Attached Storage solution with RAID 5
or
A standalone NAS box. Is there a NAS that could do all three jobs? I guess it would have to natively format HFS+ because of iPhoto...and have an iTunes server and be Time Machine compatible. A tall order?
Thoughts?

K9N Plat + RAID 1 + USB Floppy...?

First off, thanks for all the help from the forum.. I am now building my 6th MSI System for our small company, not to mention my own personal system, all using the nForce chipsets and all have been a success, a good part because of the help I have got from everyone here.
Now onto my question.
I am building a K9N Plat with an AMD64 X2 5400+ processor that is for my boss.
I want to set up a RAID 1 (two HDD, with one drive mirroring the other one) -- mainly for backup redundancy.
I found the Nvidia RAID guide, which is a big help for getting it set up, but two questions:
1.) What is the better OS to use to set up RAID 1 -- WXP home or W2K?
2.) Will the K9N recognize an USB Floppy Disk or do I need an old fashioned IDE (?) floppy disk drive to load the RAID drivers? Could I use an USB Flashkey instead of the floppy?
First time I have done this, but, for the peace of mind, I'd like to implement the RAID 1 but the floppy disk drive for the RAID drivers make me a bit concerned.
Again, thanks for everyone's help.
Aaron

It will works from standard floppy only, but you can integrate drivers in XP installation. Look here for details:

Thunderbolt audio distortion and slow Pegasus Raid Speeds

Having major problems with my MBP 17" and my thunderbolt set up. (MBP 17" 2.3 i7 quad core, (2) 27" thunderbolt displays, Pegasus R6 12TB Raid, Blackmagic Ultra Studio Pro 3D)
Apple states this clearly on there website that it is possible with this exact set up.
Issues: With all 4 devices plugged in the Raid speed goes from about 515mb/sec write to 166mb/sec write speed.
With one thunderbolt display, raid, and blackmagic I get around 460mb/sec. As soon as the second display is added to the mix the speed drops off considerably.
After Effects and Davinci Resolve color correction software cannot get sync on the Blackmagic box. Final Cut works ok.
The other really big problem is that when you do any kind of data transfer across the thunderbolt line, I cant get audio to play back for more than a few seconds. I get distortion and static in the line. I have tried the thunderbolt audio from the monitors and the Blackmagic box.
The most curious thing is that it all works on the 13" MBP. The write speed goes to 225mb/sec with everything plugged in, however it must be enough, because the audio doesnt distort and I can get sync on my color correction monitor out of the Blackmagic box.
I also tried a brand new 17" MBP 2.5 i7. I still get the same problem. It is like there is something wrong with the 17".
I have contacted Pegasus and Blackmagic. Pegasus said that they now know about it and are working with Apple.
Does anyone else have this set up and are you experiencing the same problems? Please feel free to respond with any questions. I wouldl love to hear from Apple regarding this matter. Seems like a big problem.
(other items testing)
-Switched video card to not auto switch. just use high performance.
-Went to Apple, bought a brand new 17" 2.5, stock. tested it. same exact results.
-Moved all the items around in the daisy chain to see if one item has to be first. No luck.
-Laptop monitor open and closed, same result.
-Reinstall OS.
-Brand new motherboard.
-New hard drive
-New RAM
No luck again.

This is not a surprise. Apple's software RAID is slow. The best option for using Apple's software RAID is to use a regular disk for your audio files and keep the backup copy on a RAID. Also, depending on how important those files are, you might also want to keep an off-site backup copy because fires, floods, and thefts do occur.

Using two external USB drives in RAID 1?

Is this acceptable? I initially set it up, copied files over only to see one slice degraded. Now I've been trying to rebuild the RAID but it's taking 40 +hours. Seems it would be easier/less time consuming to delete, recreate the RAID and recopy the files.
But - I wonder if this an acceptable practice or even supported (many posts say IDE or SATA drives).

Check out the Linksys articles below, if RAID 1 is not running properly then the RAID status would indicate "degraded" and disk health status "failed".

External Hard Drives for retina Macbook Pro - Thunderbolt vs. USB 3.0

I already bought a G-Tech FireWire800/USB 3.0 external hard drive and just bought a second one.
And I just found out that USB 3.0 does not daisy chain (and the G-Tech drives only have one port each), and I also read that USB 3.0 hubs are not working well on the Mac.
I think of selling the drives again (at a loss, of course) and buying a Thunderbolt drive:
Here are the two options:
1. Western Digital:
http://www.bhphotovideo.com/c/product/890519-REG/Western_Digital_wdbusk0080jsl_n esn_8TB_My_Book_Thunderbolt.html
This drive seems to have two external hard drives. Would it be possible to use one of them as the main external hard drive, and the second one as the back-up hard drive?
2. G-Tech
G-Tech also sells Thunderbolt hard drives like this one here - but it's a RAID 0 drive - can I also use both discs separately as main drive and backup drive without using RAID 0? I just trust G-Tech more than Western Digital:
http://www.bhphotovideo.com/c/product/858463-REG/G_Technology_0G02272_8TB_G_RAID _External_Hard.html
What's your take on it?
Thanks!

The NEXT THING which is upcoming now that SSD prices are dropping is Firewire to SSD, or Thunderbolt to SSD.
Now THAT will be a "did you see that?" improvement. A few home brew folks are already making their own.
run the two discs separately as one disc for storage? Yes, I however I have never had the desire or need to setup such a daisy chain. Autonomous data storage for safety is a rule I live by.
Backup VS. storage, is really a distinction without a difference.
My main PDF collection is 14 Terabytes, so............... Yes, it depends on what you need, just remember the religion of storage, 2 copies is 1, and one is NONE.
Never consider any computer a data storage device, rather a data creation ,sending, and manipulation device. Any who thinks any data is safe on any computer, even copied upon multiple partitions is making a mistake
Never backup your data exclusively upon magnetic hard drives or flash storage, nor consider same since magnetic storage degrades over time even under ideal conditions
burn important data onto multiple copies of archival DVDs and store same in cool dark fireproof safes, hidden places, secret places, multiple places
always consider and expect thy computer’s hard drive to completely crash anytime, at all times, and keep a cloned and updated hard drive handy at all times to return to immediate productivity and avoid program and parameter reinstallation and tweaking

Thunderbolt Adapter and USB for Backups to Time Capsule?

Hi,
Would there be any [speed] benefit in using the Thunderbolt port on my iMac (and MacBook Ar ) with the appropriate adapter to backup my devices to a Time Capsule, rather than just the network port, please?
I appreciate it would probably be better with my MBA over a wireless network, but the TB port doesn't seem to work :-(
Thank you.

Besides additional monitors, ThunderBolt is also for having high speed access to data. In order to do that the storage can't be just plain disk drives. They are so slow that many other bus structures can be used for them. In order to get the full functionality of ThunderBolt you must use things such as RAID Arrays that are able to move data faster.
For backup there is no really little or no need for speed and in fact the expenses involved in the high speed access would just be wasted on backup. It is really working with the data what that expensive is worth while considering.

SATA RAID conflics with POMISE T3 RAID Bios

I've read quite a few of the RAID setup issues concerning the "Extra" RAID settings under "integrated peripherals" for the K9A2 Platinum. My problem seems to be a bit unique. I can't get both the SATA RAID and the Promise "Fast Track" to work together. If I enable the Extra RAID Controllers the Fastrack Bios does not recognize my SATA RAID.
This simply means that for some reason the motherboard SATA RAID conflicts or disables the PROMISE RAID Bios and vice versa. So I have not been able to activate my eSATA ports or use anything connected to the SATA5-6 ports without going into the CMOS and setting SATA DEVICES to IDE and then turning on the EXTRA Raid Controller under "Integrated Peripherals" in the CMOS. Unless I'm wrong. I am almost sure that this scenario is right.
The second issue is that I cannot get my ram to go in DUAL CHANNEL mode. But I will post that issue another time.
thx

With Vista Ultimate SP1 on my machine the USB Flasher Tool kept on crashing when the BIOS was at v 1.2 on the KA92 mainboard.
The DOS window came up fine but it appeared that every susequent module that was brought up for detecting the motherboard caught some kind of conlfict and terminated causing Vista to summon the program terminated message box. Eventually the dos prompt would state that it could not detect the motherboard and close. All in red text. This happened only when I flashed the BIOS with v1.2. I wanted to go back to 1.3 just to verify that the BIOS version was the cause and the only reason I got back to 1.3 or 1.4 easily was becaus it was backed up by the tool so all I had to do was rename the backup.bin file(s). Again everything went as expected with the USB Flasher Tool until I loaded the v1.2 BIOS. It could not even detect the mainboard.
The only reason I didn't need the tool anymore was that it backed up the versions of the bios for each time that I had flashed the bios previously.

Mac Pro (2009) RAID Card - Can't create RAID Set

Hi Everyone,
I have a Mac Pro 4,1 (Model 2009) running Mavericks 10.9.2. with the Apple RAID Card installed. I got 4 new SAS Drives (Dell Toshiba MK2001TRKB) which I'm trying to configure into a single RAID5 set.
OS X detects the individual drives and with Disk Utility I can partition and/or format the individual drives. However when I try to create a RAID5 set using RAID Utility, the card won't create the RAID set. Ik keeps on showing the white-blue stripped progress bar. Tried creating a RAID0 or RAID1 with just 2 drives, but the card just doesn't create a RAID set.
Anyone got a clue why this isn't working?
Thanks,
Sander

Manualy erased all 4 the drives and it worked instantly. System is now initializing the volume :-)
Still a bit strange. All 4 the drivers where brand new. I did some further testing and if I select the partion tab and just create a new partition on each drive, it still doesn't work. I have to select the erase option in Disk Utility and just do a simple erase on each drive in order to be able to create the RAIDset.
Anyway, Thanks for the advise; performance even during initializing is pretty fast. I'm curious to see what kind of performance I get aftet the initialization is completed.

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

Raid setup with g-tech raid

hello there.
bit confused by this raid business. Just got a 4tb g-tech raid system which has 2 drives of 2tb each.
It shows as one disk in finder. DO i only have to set 'RAID Type' to 'Mirrored RAID set' in disk utility? Do i need to make 2 partitions first?!
its just that it still shows 4tb available and i was presuming it would say 2tb?
any clarification welcome..! Dan

I don't know much about these, but since nobody who does has happened along . . .
There are different kinds of RAID. The two most common are:
A +Concatenated RAID Set+ (or RAID-0) combines multiple disks into one volume; the size is the total of all the disks in the set. It sounds like that's how yours is set up.
A +Mirrored RAID Set+ (often called RAID-1) keeps identical copies on each disk, so if one fails, you don't lose any data, and can keep running. The size is the size of the smallest disk in the set. It sounds like that's what you want.
If all the drives are in one enclosure, they're usually configured by hardware switches on the controller, or possibly software options you can set via an app that comes with the set.
Check with the maker (or instructions that came with the system) for setup information.

Compare transmission speed between thunderbolt gigabit and usb ethernet adapters

As the new MBA has an accessory (Thunderbolt ethernet adapter), will its transmission speed be significantly faster than using an old USB ethernet adapter in one of the new MBA's USB ports?

An emphatic yes. The new t-bolt adapter should be many times faster, provided all the other links in the chain support it. I mean, plugging a gigabit adapter into a 10/100 router port, or using a slow internet connection will at least partially negate the advantages.
