Just got an Icy Box IB-3740-C31. Packaging was thankfully good as it was not delivered in a brown box around it.
Adding 4 SSD drives was a bit of a fiddling, but once the two screws per drive were attached and the sliders were in the case it was fine.
Starting up, all 4 SSDs were directly detected by my MacBook Pro.
Noise level is not super silent but ok, maybe I switch the fan later on.
Setting up a RAID-10 with Apple Disk Utility
In Disk Utility, go to File > RAID Assistant…
Who would know that once you have 4 drives you can’t just create a RAID5 with the disk utility? The only obvious options are RAID0, RAID1 and JBOD.
But there is a trick here if you want to use the RAID Assistant. Just create a RAID-10 out of 2 RAID-1 combined by a RAID-0.
First, we create a RAID-1 with 2 disks:
For my use case I used the largest block size and named the first RAID-1 raid1_1.
Then I did the same steps again with the second two disks, named it raid1_2.
Now as you have 2 RAID-1s, it makes sense to combine them to a RAID-0 – set the same block size and works fine. Named it raid10 (finally).
If you have 4 drives you get 50% of the capacity (e.g. 4x 1TB -> 2TB to use)
up to 2 drives can fail here and it would still work (1 on each RAID-1)
better fault tolerance than a JBOD
fast(mirrored & striped) compared to JBOD, single drives
a lot cheaper than a NAS
faster than a NAS with up to 10 Gbit/s via USB3.1 (Gen2, UASP)
a software raid on top of another software raid, not sure yet if you can move it between macs?
RAID-5 would give you 75% of the capacity (e.g. 4x 1TB -> 3TB to use), but only one drive can fail there
Only attached to one computer compared to a NAS – but possibly more speed
The Icy Box seems to work fine so far, and it feels quite fast (no scientific test/speed runs here) to copy large files around – it’s definitely a lot faster and responsive than the NAS in the same room. Looking forward to video editing on it.
Would have loved to go with a RAID-5 but for now I can always use the provided system tools.
gfxCardStatus is used to manually switch between integrated and discrete graphic cards on the MacBook Pro. My 2011 model had some issues in the past (before fixed by Apple) and I prefer turning off the discrete graphics card if not required. The app does this automatically (f.ex. no external monitor at work).
After using gfxCardStatus for quite some years, the app seemed to stop working after my latest OSX update run. As the latest version 2.3 by CodyKrieger has not been updated for years. However, steveschow updated and optimised it and that version works with OSX High Sierra.
