I don't seem to have very good luck with hard disk drives these days; 3 side-by-side (non-RAID) drives on my machine, replaced 5 drives in the last 4 years. My problem of the moment is that my largest drive (3000GB) seems to now be having some pretty serious read issues.
At best, accessing it comes up with erratic read/write speeds, but for the most part, I can’t even really access the data for anything meaningful and testing it seems to fail out after a bit. The SMART test on it lists two warnings under “Reallocated Sector Count” and “Current Pending Sector.”
The drive itself is a Seagate Barracuda bought in 2013. Installed at the same time was a SSD which seems to be functioning just fine (I run performance and health tests on it every once and a while as it is my primary drive). The machine is a custom build with 1000w power supply and Cooler Master case. The machine and drives stay relatively cool and have good ventilation.
Is there anything I can do to save my drive, or am I looking down the barrel of yet another hard disk drive replacement?
Answer
What specific kind of drive/model is this? Are your previous drives the same type of HDD? I assume yes if your running a RAID (what you meant by 3 parallel drives?) Regardless, this seems to be a reoccurring issue and simply "replacing the drive" isn't going to help. There's clearly an underlying issue that isn't being addressed, drives shouldn't be failing this frequently.
Perhaps it's an issue with the specific brand of drive. For instance Western Digital's green drives tend to have more "erratic" usage than others, especially if your settings or the way you access them isn't necessarily in tandem with their intended operations.
If you require this many drives perhaps consider educating yourself in HDD health, the difference between "Reallocated Sector Count and Current Pending Sector", more importantly basic HDD diagnostics and repair tools.
Here's some stuff to get you started:
Hard vs. Soft Bad sectors (part of what your SMART is flagging):

Free/Purchasable HardDrive diagnostics and scans that will tell you more than the surface scans of your SMART. They also offer potential repairs based on the Hard vs. Soft sectors mentioned. HDAT2, MHDD, SpinRite, HDDRegen, Hiren's Boot CD, Ultimate Boot CD.
EDIT: Seagate (3TB) drives have been notorious for some of the least reliable drives.
