You don't really know what you're getting with either, aside from QLC NAND. In my experience, the *X line is more likely to use a Phison S11 controller and the Vulcan line tends to use the SMI 2259XT controller. They're both low end DRAM-less controllers. The Phison drives have a very small static pSLC cache, meaning write speeds drop after only a few GB of writes. The SMI based drives usually have a much larger dynamic pSLC cache, which shrinks as the drive fills. For a QLC drive, this may be 1/4 of the free space. However, once the pSLC cache is full, the SMI drives tend to drop considerably lower than the Phison drives. The QLC SMI 2259XT based drive I've tested drops to an average of about 38MB/s, once the pSLC is filled. Additionally, I've experienced rapid, severe degradation in READ (and sometimes write) speeds on the SMI based drives.
Overall, I'm not a big fan of Team Group's flash products. I've found them to be inferior to comparable drives from other brands.

How is this versus the Vulcan counterpart?

Holy wow, thank you! Its going to take a while for me to digest all this info, but Im truly thankful you sent it so I can learn. Have a great holiday!

Sorry - I was about to start putting together a server - any companies you can recommend for Hard Drives? Or is it case-by-case? Ill stay away from TeamGroup.
I put the 2tb version of this in my PS4 and it seems like it's doing ok.
I don't plan on loading it much past half full.
I generally like to keep all my NVME and SSD at 60% compacity or less.
I keep an older 8tg WD Black in the system also and it gets closer to 3/4 full at times without any problems.

I'm not too concerned with speed.. How's the reliability of this brand?
IMO, mediocre at best.

Glad I could help. Let me know if you need any clarifications.

Hard drives or SSDs? This deal is for an SSD. For hard drives, I prefer Western Digital/Hitachi. For SSDs, Samsung and Crucial are the readily available brands I favor. Western Digital/SanDisk also has some good drives (and some bad ones). Many other common brands don't actually manufacture SSDs and just slap their label on drives made by other companies.

Yes, having free space on an SSD is beneficial for its performance and longevity (which isn't likely to be an issue). With some of the SMI 2259XT based drives I've seen, if they're kept really empty, they seem like they may functionally act as pSLC drives. They don't appear to start flushing their pSLC cache to native TLC/QLC until they reach roughly 25% full for TLC or 20% full for QLC.
Conventional hard drives don't really care how full they are. Transfer rates do drop the closer you get to the end of the logical drive (physically, the innermost tracks) and file fragmentation is more likely to become an issue, but it's unlikely to have an appreciable impact on the drive's lifespan. I've kept plenty of hard drives >99% full for long periods, without issue.

Personally, I would spend a few dollars more and get a TLC drive. QLC performance drops off a cliff as it gets more data on it. I have regretted every QLC drive I have bought.

I don't see a point in SATA SSDs when M.2 is a thing, and they're just as economical and way faster.
I agree but that assumes you have M.2 slots available which isn't always the case. Older machines don't have them and even for machines that do have them, they can be fully populated.

However I'd spend the extra ~$20 and get a Crucial MX500 (or similar well known SSD) that has DRAM, TLC, and is just an overall well respected drive.
