5D + OS X File Vault

5D + OS X File Vault
Hi there,

I just ordered my Drobo 5D and while waiting I realized that I didn't check for compatibility with the File Vault feature of OS X.

I'm running Mountain Lion, so it's actually File Vault version 2.

Any info on this?

RE: 5D + OS X File Vault
As I understand it, File Vault encrypts the entire volume rather than individual files.
In the best case, Drobo won't be able to use "thin provisioning" and will just consider the whole filesystem one giant file. You'll nullify much of the benefit of BeyondRAID. That's the best case.

RE: 5D + OS X File Vault
The first thing I did when I got my Drobo 5D was encrypt it with OS X 10.8.2. I owned it for less than an hour and found myself on the phone with Drobo tech support only to discover that encrypting the entire volume was bad bad news. It put my unit into an endless reboot loop. If encryption is your thing, plan on doing sections within the volume instead of the whole thing, otherwise you're in for a world of hurt.

RE: 5D + OS X File Vault
Damn, that seems like the price one has to pay for having these strange "BeyondRAID" underpinnings.

I really wish they would produce a Drobo that offers a "pure" / conventional RAID, for the people who are fine with buying 5 identical drives upfront.

There are a bajillion vendors who will be happy to sell you that (Promise, LaCie, etc). There's no differentiation in that segment.

RE: 5D + OS X File Vault
Actually, there is not a single alternative to the Drobo 5D in the market today that meets the following criteria:

-an enclosure that has space for 4/5/6 hard drives
-a thunderbolt connection
-a "pure" hardware controlled raid (5 or 5 + hotspare)
-does NOT come preloaded with drives (like the promise pegasus)

Granted, LaCie just released a 5-bay thunderbolt RAID enclosure, but it's all held together by OS X's software raid possibilities (or lack thereof) because it doesn't have a hardware RAID chip. Even though the LaCie "5big" is offering space for 5 disks, you can't create a RAID 5 or RAID6 because OS X's disk utility can only handle RAID0 or RAID1.

Without having touched either, I think both the Drobo 5D and the Promise Pegasus are fine products. I wish more manufacturers would offer their boxes without preloaded hard drives though.

RE: 5D + OS X File Vault
Ah, my apologies - didn't realize that Promise still bundled drives and OS X couldn't handle RAID-5 on its own.

RE: 5D + OS X File Vault
no need to apologize – convincing manufacturers that shipping enclosures with drives would be enough for now Smile

RE: 5D + OS X File Vault
If you want to use encryption on your Drobo, you can use a product like TrueCrypt (http://www.truecrypt.org/) and make encrypted volumes (not whole disk) on the Drobo.

TrueCrypt also uses the AES acceleration on the Core iSeries and AES-NI on Ivy Bridge.

Oh, yeah...TrueCrypt is free. Donations suggested. Big Grin

RE: 5D + OS X File Vault
Yes, TrueCrypt does work on Drobo as single containers on the volume, not the whole volume itself. I expect OS X encryption works similarly.
