Promise Pegasus reliability issues…
-
There are Thunderbolt to e-sata adapters.
Lacie sells one: https://www.lacie.com/it/products/product.htm?id=10574
and Sonnet another one: https://www.sonnettech.com/product/echoexpressse_esataadapter.html
The Lacie is much cheaper, about 190,00 Euros here in Italy (but you should find it at least 20% cheaper there).

What does it connect to? SAS card? eSATA card? Either way there are Thunderbolt to PCIe card chassis available:
Sonnet Echo Express
OWC Helios…but they are expensive.

Can only say the same. Our secondary edit bay is an 2011 iMac with a Pegasus that’s been running since dec’11. No hickups so far.

I will second Ken’s recommendation of Maxx Digital. I have two different raids from them, first one is still working fine after 5 years of continuous play, second one gives me 800 – 900 MB/s when 80% full. Excellent tech support.

Exactly my setup. Except my chassis died before the warranty was up. They replaced without too much issue. But before and after the chasis issue I’ve noticed that my speeds kinda, well, suck. And they’re not consistent.
The drive is only 25-30% full. It’s the R4 8th raid 5. So it has 6 useable terabytes. Read speeds when I first got it were in the 400mb/sec range. Now, they range from 80-200. This is using the BMD speed test. I can get 179mb/sec out of a single USB 3 drive that isn’t raided. In fact, I have a nextstar guardian maximus usb 3 that is a mirrored 3TB raid. So no speed gain over a single drive. It gets 179mb/sec. Why on earth would I choose the Pegasus raid over this if it’s barely faster? Plus, a mirrored raid is the best backup you can have. I worry that I can’t get the right drive to replace the pegasus hitachi ones if one breaks. And if two have a problem, you’re sol. Thinking about clearing off the pegasus and restriping and see if the speeds come back.

I had a temperature warning once. Then a firmware fixed it. They simply upped the maximum temperature. IOW, temp stayed the same, they just decided that it could handle it. Makes me wonder.
-
You can get a usb3 to esata cable for about $15 at amazon. And elsewhere I’m sure. I have one and it doesn’t support raided esata speeds, (forget what they call that) but supports the same speeds that a basic sonnet tempo card supported with my old hitachi gtech raid. About 120mb/sec. I think with the full raid support you’d pull in twice that.
-
I think it’s an eSATA connection…
Take-aways for me here are a couple:
Sounds like I can keep my Maxx Digital Raid5 array, and integrate it in a newer edit environment — good to know.
Also sounds like Promise Pegasus is a worthy contender — extra drive space is never a bad thing.
Thanks much to everyone who contributed… -
I know this is a old thread, but we had enough time to have some real life experience.
From what I can say they are not as reliable as many say. We had total of three go out completed and at least once every two months a drive would have to be replaced.
I would put my money down on G-Tech or Caldigit before I do again Pegasus.

To add to this, a friend of mine had his R4 lose everything as it could no longer see the partition. I brought my enclosure to him to see if that was the problem, it wasn’t The support there was unhelpful and they had no explanation for what happened.
Then a month later my chassis died, because it didn’t power on at all I couldn’t get their software to see the R4 so they weren’t going to RMA it. Then it was like playing a logic game with them “If I can’t give you the error codes because the drive is not working, how can I give you the error codes?”
That went on for a few minutes.
