G - Drive to RAID or not
on Jul 10, 2020 at 2:03:14 am

Am sold on getting a G-tech drive to edit my feature documentary mostly shot in 4K. Am going mad trying to figure if I should invest in a raid set up or simply buy two drives and back up. Some review complained about complexity of setting up the raid system. Also if I do go for the raid set up is it worth investing in RAID 5 or Raid O, 1 are good enough? Appreciate suggestions!

Hi Meghna,

when it comes to editing especially in 4k a raid is always a good invest.
It is much faster than any HD as a stand alone.
You have to format as Raid5 minimum. Raid6 is even better.

Thank you so much, so you reccomend creating ones own raid system or buying one that is set up. If creating ones own could you suggest drives and set up system ? Thank you !

Hi Meghna,

The minimum drives in a raid are 4 drives. With raid level 5 the amount of storage is the amount of 3 drives, the fourth drive is for redundancy. These raids usually come equipped with drives and usually the controler is within the drive chassis.
When the raid has 6 or more drives I would go for Raid 6 level, which means that two drives can have a failiure without data loss.
If the raid has more than 8 drives I would go for raid6 level plus one spare.
If you set up a Raid of your own, all drives within a raid must be the same and the HDs must meet the specs of the compatibility list, which exists from any manufacturer.
G-Tech or Sonnet or Promise or any other Raids are good invests.
Generally speaking I have never regretted the most expensive Hardware. I have always regretted the cheap ones.
Most of the modern raids work with thunderbolt 3, which is pretty fast.
What computer do you have? Does your computer has Thunderbolt 3?

cheers

Thank you this is helpful. At this point I can invest in a Raid 5 at max since I also need to upgrade my MacBook Pro to get the new one with the thunderbolt 3. Am leaning towards the G-tech. I understand Raid 5 is a safer set up, do you think making do with the Raid 1 set up is ok if there are financial limitations ?
Thank you !

Hi Meghna,

Raid 5 is a good balance between rudundancy and speed. The same with Raid 6 with an even better redundancy. With Raid 1 you have the perfect redundancy (100%) but no speed.
With just 4 drives within a Raid the only wise option is raid 5.
The best speed is raid level 0, but no redundancy. So Raid 0 is no option.

cheers

Hi all,
Has anyone had a hard drive fail in a RAID? Or two failures at the same time?
My Seagate and G-Tech drives are running after years but I have to replace one because a Firewire connector failed.
I'm planning to get a T-bolt 3 G-Tech 10 TB drive but what will I do for backup? Seagate's Backup Plus Hub at 10TB costs half the G-Tech but I can't find how fast the disk spins.

Hi Robert,

we have had several failures. It happens from time to time. No problems so far with Raid6.
With Raid5 we have had one total data loss in 15 years. We back up all files twice, plus on the raid.
This is pretty safe. We have also got a USV in case of power failure.
For every raid there is a drive compatibility list. All drives used in the Raid must meet these tec specs and all the drives used within a Raid must be the same size and Number. Do not mix drives.
A drive (24-7) dies either at the beginning (you have a 5 years warranty) or at the end of its lifetime (around 50.000 working hours)
We use only 24-7 drives from the compatibility list.

cheers

Rainer
