> I still have quite a bit of drive storage but I've read that prices on drives are on the rise. Thing is, I don't track them much. I'm looking at buying a 8TB drive and I've researched to make sure I'm getting a PMR/CMR drive. I'm avoiding a SMR since it doesn't perform as well in my use case. I tend to stick with Seagate, WD and other major makers. |

> If anyone reading this does track the pricing of drives, are they on the rise, stable, dropping or what? Is this a good time to expand while it is more cost effective? I shop around on ebay, Amazon and others before buying. I'm not opposed to buying used since I can sometimes find one that was pulled and sometimes has only a few hours of use. I found one once that only had like 10 hours on it. Still got it too. |

If you want to avoid SMR, look for the drives built for video surveillance systems. Most manufacturers have a line for that purpose. For WD it's the "purple" ones.

Other option, depending on exactly what your use case is would be to look into your choice of filesystem. SMR doesn't like random writes into one of its chunks unless it has enough idle time to go back and straighten it out later is all. There are now format options for ext4 to align its metadata to the SMR sections and to make it avoid random writes as much as it can. Additionally BTRFS, ZFS, and NILFS2 are all structured such that they tend to write from one end of the disk to the other and then jump back to the beginning, so they see little if any degradation from SMR.
