I agree with you, so maybe I should tell you more about my plans :
do backups. Of everything. That's like computer 101, lol.
My two new 3TB drives will of course by backuped, I have already older drives for that purpose (one 2TB drive, two 1.5TB drives, and three 1TB drives, so 8TB total).
My long-term goal (and yours too probably) is to have one day everything on SSD
Which means I'll need at least 6TB SSD capacity (1x6TB, 2x3TB, 3x2TB, 4x1.5TB, whatever whill be cheapest in the future). Maybe even more by then.
Performance will never be an issue, only long-term reliability.
Unfortunately large SSDs are way too expensive right now, and they will continue to be for the next few years. Prices are dropping slower than anticipated.
So my current goal is to hold on with my new 3TB drives for as many years as needed, until
the SSD prices reaches the current HDD prices (200-250 € for 6TB).
That could take a lot of time (5 years ? 10 years ?), so I'll need to take good care of my new 3TB drives. I'm not buying them for 2 or 3 years, they may need to last a lot more.
That time could be shorter IF
a new HDD technology makes its way to mass production, allowing much higher HDD capacities, consequently lowering HDD price per TB, and as a side effect forcing SSD manufacturers to lower their prices too.
But let's not count on that right now.
That's why I need to be sure that I'm making the best possible choice now : I need (1) long-term 24/7 desktop reliability and (2) quietness. I don't care about performance.
Small details like the LCC (hence drive parking) can become important over time, especially for 24/7 use. Other details like TLER may be less important since the drives will be backuped anyway.
Bottom line : I would go blindly with the WD Reds right now
, because they are intended for 24/7 use, and because of their 5 min head parking time.
WD Green/Blues may be quieter (not even sure) but they're not meant for 24/7 and their 8 sec head parking time is a no-go for me.
Only reason I haven't bought WD Reds yet is because they seem to have become louder
with the Nasware releases (if only we could change our Nasware version I'd go back to 1.0, lol)
But even with Nasware 3.0, the WD Reds seem to be quieter overall than other models. Only the head parking noise
(noise, not time) seems to be an issue.
Only after buying them will I be able to decide if that noises (seeking, parking) are an issue for me in my environment or not :
- If they're not, then good.
- If they are, then I'll need to find a way to deal with that for a large number of years. Hence my question about tweaking the head parking time, or permanently disabling it. Or about finding silent hard drive cases, which we can't seem to find these days (plus they're ridiculously expensive).
I hope this explains things better.
