Promise Pegaus R4 vs G-Drive4G+G-Raid4g

Hi, i'm looking for a good video-storage-setup to put all my video files and fcpx projects, whit speed around 300MB/s and about 3-4TB space, and some security/backup. This wil be conected to my Mac when working inhouse. A will also have a backup disc conected to my nas (in the garage) so I can have automatic backup.


My question is should I go for a Promise Pegaus R4, in Raid 5 or shall I go for one G-Raid 4G in Raid 0 and one G-drive as the indor backup. The price wil be allmoust the same. Bouth solutions wil be bacuped up to the NAS outside the house.

Thanks for any replay.

Are you panning on getting the G-Technology with Thunderbolt?
The main benefit I see with the Promise is that you can replace the drives easily.

We use both Promise and the G-Technology drives (no Thunderbolt yet). From my experience I have more trust in the G-Tech drives. We haven't any issues with the Promise Pegasus but we did with the VTrak with Seagate drives.

But the Pegasus are fast thanks to Thunderbolt, but I can imagine the G-Technology are as fast.
Oh by the way G-Technology only use drives from there mother company Hitachi.

Yes

Hi, what do you think about lacie 5big thunderbolt? Set it up whit tree disk in Raid 0, and two disk in Raid 1 as a "backup" for the Raid 0?

I don't "think" you're doing to see a huge performance difference between RAID 1 and 0.

Not sure a RAID enclosure like that will let you divvy up the array. Will it? Normally you can only do that on larger arrays.

From what I can read, you can set it up as 3 disk in raid 0, and 2 in raid 1. And have the two as a backup for the raid 0. The only thing is that the raid 1 is limited two the capasity for one disk, so you don't have perfect solution.

I think the pegasus whould be a nice solution for me, but from what I can read on Appel.com comunity many has problems whit them.

My group has 4 Pegasus R4's and have been using them for over a year. During that time I have had two instances of the drive disconnecting that I cannot replicate nor can I definitely say it had anything to do with the Pegasus itself. One other user had a drive fail but continued to use the RAID until a replacement drive was shipped from the manufacturer. Overall my experience is positive with the Pegasus R4 product.

I have had more problems with LaCie drives in the past although LaCie drives I have used recently seem to be OK. I have not ever used a G-Raid so I have no input there.

FWIW

Remember that online forums are only used by folks with problems. There's many more users without problems that have no reason to go on forums.

Thats a very good point Ben!

Maybe I should go for the Pegasous.

I've no clue.

I'd go for the Pegasus for a few reasons:

1. It's damn fast. Really damn fast. I also choose to run it in RAID5 so that if 1 drive goes down, they all don't die.

2. The G-DRIVES while I'm sure are nice, contain two 2TB drives in a RAID 0. If 1 drive fails, the whole system goes down. And you can't replace it. For my money, I'd rather have the option to spend $150 and save my investment.

3. RAID 1 is most certainly slower than RAID 0. I find that RAID 5 is a nice balance. You take a slight hit on the write, but the read is still blazing (or is it the other way around?)

Having the Pegasus operate as a RAID 5 and backing that up to an external NAS is all you need - you shouldn't need to have a triple backup unless you are super paranoid

I bought the 4TB Pegasus R4 and swapped out the 4 1TB drives with 2TB drives. One of those 2TB after market drives failed on me, which is why I'm thankful I have a RAID 5. Most likely that was a drive failure however and the system alerted me immediately before the failure actually happened, so I was able to prepare. Something about bad blocks when it did it's routine maintenance on the drive.

I think you'll be happy - remember, hard drives are an investment!

Good luck!

Thank you for some good words, and som pointers from you're experience!

One Pegasus R4 4x1TB is comming my way

I start whit the org. 1TB disc, and set it up as Raid 5. I will plug it in to my Thunderbolt Display, and backup it's contend over to the NAS (in the garage).

I'll give you my experience whit the system, when it's up and running.

Thanks,
Klaus
