Hello,

I've been using my Pegasus 2 R4 8TB (Raid0) for the last 10 years and it's been incredibly solid for everyday use. I'm a video editor and also use it to back up photos, home videos, etc....   I've only had 1 drive fail and did not lose any data that Im aware of. I don't want to press my luck and need to replace ASAP.

I'd like to upgrade the R4 to 12TB but it seems all the tested drives from the link below have all been discontinued. Has anyone recently upgraded using a newer SATA III 3.5 3TB HDD? Any suggestions to a drive that would be compatible? Do I need to stick to 3TB or can I drop a 4TB drive into the array and still have it function properly.

Could this drive work for my needs?

Huge thanks in advance for any guidance.

Hi Jeremy,

The Pegasus 2 was first sold in 2013 if memory serves. All the drives tested with it are most likely long out of production.

I'm not sure of the maximum size drive that will work, but the compatibility guide will show you the largest drive tested, that's the most useful information in it today. I recall some forum posters say thay have use 8TB drives.

The general recommendation is to buy a new drive, preferably from the same manufacturer with the same spindle speed, which will be 7200 RPM. Of course you can use any drive manufacturer, there are only a few left today, but drives from the same manufacturer are more likely to have similar characteristics, which helps the raid set work better.

The drive you selected is not a good choice.

This drive is 5400 RPM, you don't want to mix a 5400 RPM drive in a RAID set with 7200 RPM drives.

If you were to replace all the drives and make a new RAID, you could use this drive. But the Pegasus will be slower and may not be fast enough for video work.

Thanks for the quick reply RP!

Apologies, my original post was not clear.

I plan to updgrade ALL 4 drives making it a 12TB array (or 16TB?) Currently my Pegasus 2 R4 is confugured with 4x2TB drives. Can it be configured to 16TB?

Would these drives below be a good option?

I'd really like to continue using my Pegasus 2 for back ups, photos and such. Hoping I can just continue using the latest drives available or if this particular model is soon to be obsolete?   

Thanks again!

Jeremy

Hi Jeremy,

The 4TB Ironwolf drives should work.

And a 16TB array should be fine, in RAID5 you should have a 12TB Volume.
