The HHD of iMac 21" is 2,5" so this adapter does not work.

Correct. I don't own a 21" but my guess is that you might have enough room if you affixed two 2.5" drives to each other using double sided tape - especially if you used the slimmer form factor 7mm drives like the Samsung 840 Pro.
 
Hey guys! What is the best way to install windows 8 natively on a Raid Imac?
(No virtual machines). My bootcamp is deactivated because my RAID 0 setup :mad:

Thanks! :)

What do you have for drives in your RAID-0 now?

I just created a RAID-0 with a 512GB SSD and a 256GB SSD (matched series) where I divided the larger SSD into 2 equal partitions. I then joined 1 of the 256GB partitions with the other smaller 256GB SSD in a RAID-0 (512GB) for OS X, and used the remaining 256GB partition for Windows.

I had also considered using a pair of 256GB matched SSDs and partitioning both of them with a small 100GB partition. Then RAID-0 the two larger partitions for OS X, and put Windows on the smaller partition of one SSD while formatting the other drive's small partition as NTFS for Windows program storage.

I got 256gb blade + 256gb 840 pro. My best bet then is to create a raid of 156gb + 156gb in raid and have 2 other normal partitions of 100gb each? (1 of them is going to be for windows and the other one for spare archives?)
Is the raid going to have the same performance as it will be just 256gb+256gb RAID0? Correct me if I didn't understand correctly the process!

Thank you very much!

That should work, although you're RAID-0 members aren't matched and you will not be seeing the performance capabilities of the 840 Pro in the OS X RAID drive since it is striped with a somewhat slower "830 class" blade SSD. I am assuming here that your 256GB blade SSD has similar performance as the Apple stock 128GB they normally use as part of a iMac Fusion drive??

Or ... Since you have a 256GB blade (cool!), you could add a 512GB Samsung 830 2.5" SSD and RAID-0 half of it with the blade to get a 512GB OS X environment, and then use the remaining 256GB on the Samsung for your Windows environment with BootCamp.

Did you start with a Fusion drive in your iMac and upgrade the SSD? I also took my experiment with the combo RAID-0 and Windows on 2 physical SSDs to the next level ... I used the RAID-0 SSD as part of a DIY Fusion drive with a 3TB hard drive. That also is working well.

For this 256gb blade + 256gb 840 pro customization I just got a top processor + 2gb graphics and I ordered the rest on ebay (32gb ram , blade, 840 pro) As i did in the previous customization that you can find in this topic as well (512gb blade + 512gb 840 pro)

Unfortunately Bootcamp doesn't work with the solution that you suggested, there is a way to install windows using an external HD? (Like the stock 1TB HD with a 3.0 usb enclosure?)

I have a question about those 4 connectors that you can see in the picture that I uploaded, the first in the left came out badly and I had to fix it by myself. What is the task of that cable? How can I test if it is working properly there is a way? Thanks a lot!

Those cables are the coaxial antenna leads which go to your WiFi and Bluetooth antennas. If you have damaged one of them you may experience less range as they are multi-antenna arrays. What damage to them is evident? Is the damage on the cable connector or the circuit board connector?

I have the 2-SSD RAID-0 / Windows 8 running in my 2012 Mac Pro (sharing 1 of the SSDs for Windows and half of the RAID-0) and had no problems installing Windows directly from the DVD disks via BootCamp. Combining this setup into a DIY Fusion drive was also performed on a Mac Pro. I have not done a RAID-0 in my iMac as I have the 768GB SSD model and no second drive cable/mount.

I have also installed Windows 7 to both internal and external Thunderbolt SSDs on the 2012 iMac using the external USB SuperDrive (there are some threads here on different methods to get the external drive to install). I had no trouble using the USB SuperDrive to do this on the iMac ... however, I was unable to install Windows on a 2011 Macbook Pro using an external USB SuperDrive and had to temporarily reinstall the internal optical drive to get Windows installed.

In all cases, I used the retail DVD Windows disks to perform the installations, not the USB ThumbDrives some others here have tried with mixed success. What type of problems are you having when installing your Windows?

The problem is on the board. There is some way to test if that component is properly working by using a software in mountain lion? (able to check the wifi/bluetooth hardware components)

My bootcamp doesn't proceed after the first window if I'm with a RAID0 set up. Even after trying your suggestion I got the same problem.
Do you know where I can find a tutorial about how to install windows 8 in an external HD usb 3.0?

Many thanks for your support!
 
So, I may not need that if I am just adding another lightweight SSD drive in there? I can simply "velcro" the drive in place if necessary.

Perhaps the only difference in the "Mechanism" is the tension of a spring or something to maintain the balance point with a hard disk in there.


-howard

I also had trouble finding those parts but i emailed AppleComponents.com and they have added those parts. SO you can now buy both the cable and the mechanism from there.

If your WiFi and BlueTooth is working, you may not have a problem. If you can find a manual that identifies which cable is which, you may be able to determine if the damaged connector is working by disconnecting the alternate cable for that function ... if that function fails to work at all with only the damaged antenna attached, then the damaged connector has failed. Actually, you might be able to tell simply by disconnecting the other 3 and seeing if both WiFi and BlueTooth no longer work. Of course, you risk damaging one of the other connecters by messing with them. :(

I had an opportunity to create another mixed OS X RAID-0 / Windows system with 2 SSD drives, and found that using BootCamp from OS X to create the Windows installation complained that it couldn't modify the boot volume (because it was a RAID-0). So I installed Windows by booting from the Windows DVD and installed it directly to the non-RAID half of the larger SSD that way, and it works. I may have done that last time as well, but I don't recall. I was using a 512GB and 256GB Samsung 840 Pro SSDs to create a 512GB RAID-0 for OS X using both disks, and a 256GB Windows environment with the remaining space.

You mean 512 840 Pro + 256 blade (Samsung 830), right?

I'm sorry, I thought I clarified in a post above that this was in a Mac Pro, although the same setup should work fine in a iMac as well with the blade SSD. The ones I am using are 2 standard Samsung 2.5" 840 Pro SSDs, one a 512GB, and the other a 256GB.

Sorry for any confusion... :eek:

Ahh, sorry about that. Can you give any pointers on running OS X on a RAID0? Backup process, things to check, watch out for, etc? Did you leave unpartitioned free space on your SSDs to keep performance in tip top shape? Did you enable TRIM and if so, can you confirm that it's doing its thing properly?

Running a RAID-0 disk is no different from running a single disk ... just much faster and you get twice the disk space (sum of the drives). The backup process is the same, I use Time Machine to backup to a NAS, and a regular CCC clone to an attached drive for quick recovery and additional copy of all data. Restoring from a backup to a RAID-0 is also the same. You need a backup no matter what type of disk system you are using!

I let the SSD manage itself using whatever over-provisioning it was designed with, and don't reserve space. I do have trim enabled and it shows as active in System Information ... I assume it is working as I have no way to prove otherwise.

I have been running OS X on RAID-0 system disks for years using both hard disks and SSDs with absolutely no problems. Speed is great! :) :) :)

1TB hard drive plus ssd

I've read through all 34 pages of this thread at some point or another looking for an answer to a specific question, sorry if its already been answered.

If you purchase the 27" 2012 iMac with a standard - non-fusion 1TB drive, is it possible to add an ssd in any way? Either and 830/840 or an apple blade style ssd?

I guess the more specific questions, is there a connector available in addition to the 1TB standard already being attached? Is there room? and if the connector is available, is it on every 27" model? or more specifically an i7 model.

on the 27" 1tb you still get the blade ssd slot. I bought a 1tb i5 27" and have the slot although I haven't used it as I just put a 500gb 840 in place of the 1tb (as the blad SSDs are so expensive)
 
Reply to Question

Awesome, thanks for the quick response. I'll take a look around for a blade drive and consider my options. I'm not really digging the whole external drive option.

----------

Does anyone know in particular which blade ssd's will work? Apple or non-Apple. Are they all the same?
