Upgrading a Pegasus Promise RAID?

[allthingschris]

Has anybody had any experience upgrading the drives in a Pegasus Promise RAID?

My current setup is the 6x2TB model, but I'm running low on space. I'm considering buying 4TB drives to replace each of the 2TB drives.

1) The cheapest drives are Seagate 4TB external drives. But conceivably I could just take these drives out of their enclosures?

2) The other alternative is 4TB Hitachi disks but they're considerably pricier.

Any thoughts, feedback or advice? Thanks in advance!

Don't quote me, but I thought I read something somewhere about the R6 only being able to use up to 2TB disks to remain stable. Something about the firmware. I'm sure it will be addressed at some point.

I don't think Promise is using enterprise drive and if they really don't just get their cheap 4 bay TB RAID and swap out with Hitachi Enterprise drive.
Don't take any chances on the RAID.

I just checked the Promise compatibility list. They list only the Hitachi 1TB and 2TB drives at this time. They also state they only recommend enterprise class drives.

In RAID storage system, we recommend user to use enterprise level hard drive, which has much better command timeout control and more reliable to vibration for critical application.

Personally, I would not use consumer drives in a RAID array. Your most conservative next step would be to buy a second R6 and chain them. It would not be cheap... but if you have that much data, then something must give.

A cheaper solution would be to get a cheap 3TB or 4TB usb drive an move some non-critical data (if any) to the slower devices.

The compatibility list now have a 3TB Seagate drive (ST3000DM001 in two different flavors).
