Hello
I have a WD Ex2 Ultra. It was purchased with two 2TB drives. I would like to change to larger drives (2x3TB or 2x4TB). Will it work with larger drives?
Do I need to buy WD RED drives or can I use Seagate Ironwolf or Toshiba N300 drives?

I have tested on a few of my NAS units using all Seagate Ironwolf
seems ok after 6 months
You may want to note any temperature changes or extra noise in your use area.
my local store has WD RED pro on sale sometimes so I have backups if needed.
I do make all disks in a single NAS all the same type and model
I’ve had a WD Ultrastar DC HC550 18TB drive in mine for over a year now. No issues whatever.
Hi, is the EX2Ultra drive compatibility list current? It seems very limited and at the top of the page it states 4k drives are not compatible, yet elsewhere on your site it states even the basic Red drives are now 4k. Before we even get in to other vendors drives can you get a definitive list of what WD drives will work in the EX2Ultra please?
Many thanks
Thank you for the information, maybe this time I will buy Ironwolf.
I’m still wondering if if I put 2x4TB in there will it work without problems? I originally bought 2x2TB but I’m thinking about increasing the space. I have 2 USB drives connected, but it’s better to have more on two internal drives in RAID.
I found at one time that the 4 TB disk had the best price and it was cheaper to get a second NAS than to pay for 8 TB disks.
I see the disk tables have not been updated to follow the new larger disk size !
Hope some one has tried - but We could look and see what other NAS vendors with units from about the same time line recommend .
My other NAS DS920+ has the same iron wolf 4 TB as my WD NAS units.
Pretty much any drive will work in the MyClouds. But I would seriously consider upping the drive capacity even more - you will soon run out of space with 2x4TB. 2x10TB seems to be the sweet spot right now, price wise, and they work just fine in the MyCloud.
I bought my EX2 Ultra already factory equipped with 2 x 4TB WD Red drives so there’s no problem using 2x4TB drives.
I believe the Wd My Cloud Ex2 Ultra can support up to 22TB Drives.
I have had problems with some Seagate Ironwolf drives. I can’t get a detailed answer from WD but it appears that the My Cloud Ex2 Ultra only supplies around 9-10w to each drive and all of WD Disks operate at under 9w. Some of the Seagate Ironwolf disks operate at over 10w. I’m not sure where the cutoff is for drives to work or not but I can confirm that some of the Seagate Ironwolf disks will not work in the Ex2 Ultra and the operating w of the disk seams to be the reason.
you could test with ONLY one disk in the EX2
I have two 4 TB iron wolf drives in mine
I plan to watch the voltage on the power brick if I go to 8 or 12 TB disk units -
