Is it safe for me to expand my pool?

<div class="bbWrapper">They don't need to be the same make and model, or even the same size, as the existing disks in your pool.</div>

<div class="bbWrapper">ZFS isn't picky about hardware at all. You can do all sorts of bad, silly, dumb, clever, etc., stuff.<br /> <br /> Don't confuse ZFS with FreeBSD. FreeBSD really needs stuff like decent HBA and ethernet controllers in order to provide a good NAS experience.<br /> <br /> I generally recommend heterogeneous pools (pools made up of devices not all from the same mfr) for various reasons. I'm not sure mixing 3.5 and 2.5 drives is a good idea, but it probably wouldn't kill you.</div>

<div class="bbWrapper">OK ! Thank you for the update ! so I could expand the pool by 2 TB by adding a mirror of 2 x 2TB drives - right ?</div>

<div class="bbWrapper">Ahhhh... yes, but you probably don't want to, most 2.5&quot; 2TB drives are SMR, I think.</div>

Check the list of SMR drives and particularly for 2.5”, check against the additional list references in the notes there.<br /> <br /> 3.5” is a safer bet, just avoid the wd red efax 2/4/6TB, and any “not nas” drives such as barracuda. Red pro, ironwolf / pro, n300 are all safe choices.</div>

<div class="bbWrapper">Thanks ! - <br /> Yes - I was thinking IronWolf ... watched some YT videos yest about that sneaky SMR on WD Reds (which I almost got) and then I saw the Seagate drives (not IW) were SMR...good to know also about WD Red Pro -- looking forward to adding the storage ...will need to convert 5.25 drive bays for extra 3.5 drives ... thank you all --</div>
