[SOLVED] Best modern equivalent of these drives to upgrade my RAID?

[Cyber_Akuma]

Back in 2012 I setup a hardware RAID5 using four 3TB WD Red drives, I have had to RMA one of them since so it's a slightly different drive.

Anyway, I am planning to upgrade it to a RAID6 and add a SSD cache, so I want to get another drive that matches what I already have as closely as possible. I know I can't get the exact same model, but I want to know what is basically the modern equivalent of these models. Especially since apparently the WD Reds of 2012 are not the same thing as buying a WD Red today and there is that whole SMR/CMR issue which wasn't a thing back when I got these drives:

There isn't a speed listed on them, but from what I can tell looking up the old model number, apparently they are 5400RPM drives? (Could I have sworn I used 7200) with a 64MB cache and are CMR.

What would be the best modern equivalent of these drives today? I wouldn't want to get something that impacts the performance of the raid by being SMR or something lower-end than what these drives were in 2012.

That's a 3rd party selling a used one through Amazon.

All the ones I could find were third parties through Amazon, Nerwegg, etc, couldn't find any that were being sold by the actual store.

hmmm im not sure about that
anyway
https://shop.westerndigital.com/products/internal-drives/wd-red-plus-sata-3-5-hdd#WD30EFRX
here is western online shop, from url name u can tell that it redirects you to WD30EFRX site
some product description tells you up to 150MB/s transfer

now scroll down a bit and u can open data sheet
https://documents.westerndigital.co...uct-brief-western-digital-wd-red-plus-hdd.pdf

scroll down to 3TB drives, only 2 are present
WD30EFRX CMR 147MB/s 64MB cache 5400rpm sata
WD30EFZX CMR 175MB/s 128MB cache 5400rpm sata

well...as far i can tell..wd lists that some drives arent available in some countries...so that could be why u cant find it in your area
in case WD30EFRX is not available in your area, u can still go with WD30EFZX, bigger cache in raid setup on single drive has no impact on raid (unless that cache fails during power outage)
