SMART support for OWC Elite Pro Quad via USB on older Mac

My target Softraid setup:
-- OWC Elite Pro Quad
-- Connected to Mac Mini (Late 2012) via USB 3.0

Anyone with a similar setup who can confirm that Softraid can read SMART from disks via USB 3.0?

Alternatively
-- Would a USB-C connection via TB1 (on the same older mac) work?
-- Do I need a newer Mac supporting USB Gen 3.1 or TB 2/3 for Softraid to be able to read SMART?

Thanks for your help.

Kind regards, Gerhard

I connected a Elite Quad Pro to some older machines.

SMART over USB is not available except under USB 3.1 or Thunderbolt.

If this changes, I will update this post.

I'm also curious about smart on Quad Pro and Mac Pro

I just got card below:

it says it is 3.1 card, does above setup supports smart?

Quad Pro and 1344A card?

Thanks

I have question about the same product on MAc Pro 4.1 upgraded to 5.1 12 cores 3.4
OWC Elite Pro Quad
Connected to RocketU 1344A 3.1 USB PCI card
http://www.highpoint-tech.com/USA_new/series-ru1344a-overview.htm

Does this card provide SMART over USB? Since it is USB 3.1 ? What PCI card would I need that was tested to have SMAT reporting?

Regards,

Why not connect a disk to it and let us know. The problem is generally the enclosure, though, not the drives. Most WD single disk enclosures support SMART. So do the LaCie, G-Tech and Seagate drives we tested. Toshiba varies by enclosure. Seagate was the most consistent, all three of the enclosures we tested supported SMART.

It looks like OWC Mercury Elite Pro Quad does not support S.M.A.R.T

When I click on any of the drives under USB bus, it says NOT Supported.

So followup question:

How with this enclosure I will learn about failing drive? Is it only when it fails I will get email (Configured) that drive failed?

SoftRAID formatted disks still track disk errors. So when there is an error, you will be notified.

This is often later in the failure cycle, but at least you will get a notice that the drive has issues.

We are investigating technology to try to predict early failure even when SMART is unavailable.

Just to chime in here, Mac Pro 3,1 (Early 2008), this is what I see:

Mac System Report
USB
Registers Mercury Elite Pro Quad S.M.A.R.T status as Verified.
D S.M.A.R.T status as Verified
C S.M.A.R.T status as Verified
B S.M.A.R.T status as Verified
A S.M.A.R.T status as Verified

SoftRAID XT v5.8 Driver v5.8
All these 4 drives currently undergoing verification, show SMART status: passed test

Note: I have 5 internal drives (using lower DVD tray as well), and two are marked as having disk failure predicted. I stick to Western Digital drives as Seagates I've had major issues with over the years. AND more notable, is that ONLY SoftRAID XT has given me a report of unreliable sectors on these failure-predicted drives.

The enclosure does support SMART.

The key is if SMART Is enabled in SoftRAID. And, if you get your app quarantined, then it won't show SMART data. (In Mojave, by installing the SoftRAID app that is copied from another computer will quarantine it.)

I should add, I'm on El Capitan, and the two marked drives are NOT in the enclosure. These are old Mac volumes on the internal. Also, the Mercury Elite Pro Quad is on USB out the front, which is USB 2.0 methinks. Definitely not 3.x.
