I have five 6TB drives in a QNAP TVS-672XT 6-bay NAS, one of which is Red Plus and the others are Red Pro. I am planning to purchase two more drives, one to fill the 6th bay and one to replace the Red Plus, which I just realized is only 5400rpm. I am considering the following:
- Buy 2x Red Pro 6TB at $199 each - This will result in my NAS having 6 identical drives
WD acoustic specs indicate 29dB idle and 36dB seeking. Speed is 238 MB/s and cache is 256 MB.
- Buy 2x Red Pro 16TB at $249 each - I don't need this much space. However, I noticed WD is currently running a sale for $499 total for two of these drives. It's tempting to "future proof" in case I eventually need more space, but maybe it's just a waste of $100. (To take advantage of the extra space in a RAID 6 setup, would I eventually need to upgrade the other 4 drives to 16TB as well?)
WD acoustic specs indicate 20db idle and 36db seeking. Speed is 259 MB/s and cache is 512 MB.
- Buy 2x Red Plus 10TB, 12TB, or 14TB at $199, $229, or $259 each respectively - 10TB is the smallest option I would consider for Red Plus since the lower capacity drives are only 5400rpm. I would consider this option if noise will be significantly lower and performance not noticeably different from Red Pro. Though, I see also that Red Pro has a longer warranty.
WD acoustic specs indicate 34dB/28dB for the 10TB model and 20dB/29dB for the 12TB and 14TB. Based on that alone, I would probably avoid the 10TB, but not sure if it's a noticeable difference in practice. Speed is also listed at 215 MB/s and 210 MB/s for the 10TB and 14TB models, but only 196 MB/s for 12TB. Cache for all three is 256 MB
Will there be much noise or performance difference between these options? I'm also wondering why the 16TB Red Pro is on sale. It seems that this particular drive has been on sale before and I'm wondering if there's any particular issues with it such as excessive noise compared to the other Red Pros.
I also see slight differences in power consumption, with the 10TB Red Plus using the most energy of the three Red Plus options and the 16TB Red Pro using slightly less energy while in use but slightly more energy when idle compared to the 6TB. Not sure if the difference will be noticeable on my power bill.
I am mostly using the NAS to store my photos and videos, with some photo editing in Lightroom/Photoshop and video editing in Premiere. Also planning to start backing up to Backblaze and setting up VPN for remote access to my files. Read/write speeds are currently only in the 200-300 MB/s (over Thunderbolt 3 connection to MB Pro), so I'm hoping to speed things up.
