August 19, 20232 yr Just had a drive fail so looking to upgrade my 2 6TB parity drives(WDC_WD60EZRZ) with bigger capacity ones, then move the 6TB parity drives into the array which can replace 5 older 2TB drives(formatted as reiserfs, yep they have been running a while). Can get the Toshiba 18TB MG09 for approx AUD$610 Seagate 16TB Exos is the same price, leaning towards the Toshiba Thoughts? Regards Mitch

It's been on the market for only two years. Not enough time to call it a proven tech. I wouldn't put it in my NAS when there are similarly priced, well proven alternatives.

Are they that much more expensive as compared to the MG09? How about externals? The last time I shucked an external Seagate a couple of years ago it was significantly cheaper (but with a shorter warranty) - came with an Exos in the enclosure. Other externals I did had Ironwolf Pros included. Edited August 19, 20232 yr by Lolight

Eventually yes, as I want to reduce the number of drives in the system, down to say 6 total, 2 parity, 4 data, will go the 12TB or the 14/16Tb the only real difference between them, besides the price, is the Cache, 256MB on the 12TB and 512MB on the 14/16TB, not sure that would make a difference on my system? Why do you ask? Edited August 20, 20232 yr by Compass

Regards Mitch Yes I have 2 x 18Tb for Parity, 1 x 18Tb data, 14TB to be added. Slowly replacing old drives and consolidating.

I've ask because taking 16/18TB as parity is pointless if other drives are smaller - no real benefit - longer parity check (have 12TB drives on parity - it takes 20-22h to do parity check) right now you have 26TB of space (12 drives - 10 data, 2 parity) - buy 3 14/16TB drives - 2 for parity, 1 for data - finally you get 26/28TB of space (6 drives, data 14/16TB + 3x 6TB, parity 2x 14/16TB) and in the future replace 6TB with 14/16TB
