I'd suggest Areca's ARC-5026 4x drive external RAID enclosure. It is more expensive than your other options, but here's what it can bring to your party:
- USB 3.0 and Thunderbolt connectivity (unfortunately this is pretty rare and would allow you to plug into your old Mac and your new iMac 5k)
- RAID done "right" (with a decent controller) and including RAID 5; you would put you existing disks in now, and grow down the road
Here's a link of various external Areca solutions available at Newegg:
Looks good JE! Thanks for the link. I wonder, if I would buy the Areca with 8 disks, can it also be configured into 2 sets of 4 disks in RAID5? I want to have my files really physically backed up / existing as 2 real copies. A single RAID 5 setup protects against disk failure, but not against accidental loss of files. So for my next workstation I am planning two RAID5 sets (or one JBOD set + one RAID5 set). So I could buy 2 separate enclosures of 4 disks with RAID5 option. Or maybe just one Areca 8 disk solution that can has it disk drives configured in multiple ways?
Jim, many thanks for the feedback. While that looks like an ideal setup, my budget can't stretch that far and it's possibly overkill for my current requirements.
After a lot of research and working out what would work best for me, here's what I've gone for:
Working assets drive
LaCie d2 4TB Thunderbolt 2 (up to 220 MB/s) (up to 1150 MB/s with SSD Upgrade).
WD 4TB Elements Desktop Hard Drive (up to 126 MB/s).
This way I have satisfied my requirement for more storage space and have an option to upgrade the D2 for insane speeds if I feel I need to in the future.
I've decided to continue my current backup process of doing regular clone backups as opposed to using a RAID 1. For this purpose the 4TB WD will suffice.
Sorry I interrupted your thread with my own question.
Two important questions are:
1. Did you order your new Imac with a SSD or HDD and which size
2. 2TB external drive which you already have - is it USB 2 or USB 3 speed?
One route which may be interesting, especially when on a smaller budget, or just want to make use of hardware you already have would be to make use of cheap and flexible hard drive docking stations like this one:
And this in combination with an external harddisk set that has at least 2 drives so you can put it in RAID0. Your setup would look something like:
- Imac 5K for OS & Applications
- 2 x HDD in RAID 0 for your media. like the "WD My Book Thunderbolt Duo 4GB with RAID 0 & 1 support for $499"
- 1 x 2, 3, or 4 TB drive in a docking station for backup of your RAID 0 media drive, and as export drive when you make your final renders
- If your old 2TB external drive is USB 3 you could use it for scratch drive. When it is USB 2 it is probably better to include the scratch drive on the RAID 0 drives, or on the Imac5K drive if you choose it with an SSD.
In this way you will have both a fast video editing multiple harddisk setup and a full backup solution of your files on two separate locations / instances.
