WD HDD Industry Will Be Supply Constrained Due to Thailand Flooding
Sosseres:
To get different batches shouldn't you buy a popular hdd with time between? Like one now and another one in three months from the same (large) retailer? Since so many HDDs of that type has been sold in that time period a new batch is the only likely thing.

Well, yes. But I need to buy at least five drives at a time (minimum) since I use a 3+2 configuration (2 redundant drives per five drives).
And buying all five at once would mean that each slice (which is where batch allocation really matters) would still be the same batch.
One alternative, if you trust the drives to last a few months at least, is to use mirroring instead of raidz2, and buy the mirror drives later (that is, set it up as a normal non-redundant stripe first, then add redundancy a few months later on).
Considering that one out of my 20 drives failed the first week that is probably not a good idea, though.
You could set up a smaller mirrored pool, then add more drives, copy the data to the new drives, verify the copy, split up the old pool, and re-add it as mirrors to the new drives. I guess. Sort of a lot of work, though.

Or buy different models of drives? Like one WD, one seagate and so on. Since they get bought at different intervals from making it doesn't matter that one or the other is just a re-branding. Though local retailers here only carry 4 different brands of 2 TB discs.

One major issue with using multiple brands (and also the reason that I am restocking on 2Tb, not 1.5Tb drives) is that they are usually not the same size.

All of this does suck for people with large person servers who suddenly need more space.
I personally just ended up buying some blank media (DVD-R, BD-R) with the money I was going to use on another drive. Putting the movies and shows Ive already watched and tend to not watch again on a shelf and deleting it off the drives.
As for buying different brand drives so you dont get multiple bads from the same batch, most hardware RAIDs dont like that at all. You could always use a software RAID though. Plus side to that is you can do something like AnimeJanai mentioned where your new, largest drive replaces the oldest, smallest on your RAID while keeping the RAID intact.
Edit: And to add to the SSD comments. No, it wont touch their prices at all as they are a completely different manufacturing process at completely different facilities. They are also NOT a good alternative for what most people are using large hard drives for anymore, mass media storage.
Though I can see more people opting for a SSD as their main system drive now that the Price per GB is so close. I myself just bought one for my Laptop, whos drive just took a dump on me.
And there is no such thing as a "cheap and reliable SSD", at least not right now it seems. It seems the last couple generations have had some serious controller issues.
