There are a number of terrible QLC-based drives, like the Intel 660p, Sabrent Rocket Q (shame on Sabrent for associating the model name of their better-performing Rocket drive w/TLC!), etc.. I put them on the same low-performance tier as DRAM-less SSDs - that is, the tier of "do not buy". You're basically not saving any money over much higher-performing TLC-based alternatives (not DRAM-less) the way they are pricing the QLC drives.

I would only use a QLC-based SSD for large storage wherein you can make backups to it that happen overnight or some time when you don't care about the much slower performance of the drive. Also, your use case dictates that you can only fit a SSD instead of a cheaper (and larger) 3.5" HDD (or two).

Form a pure performance standpoint you're slightly right right.. But it all depends on the use case!

For Youtubers/streamers recording and making videos those lower level disks makes a bad purchase, but for storage, movies, games libraries and backup their excellent value.

Most people don't overwrite their movie libraries, game libraries or backups that often, and the main downside of TLC is their endurance.. But if you use it for weekly backup, they should be good for about 20 years of backup before you hit the 1000 rewrite MTBF (and i know NOBODY that runs 20 year old HW), Reading is not the problem for these discs, it's writing.

I run a 660P for my steam library, and I'm more than happy with the performance. I know its a few seconds slower than the fastest SSD's, but most people won't notice the difference.
A game like Metro Exodus, will load as follows:
High end NVME SSD : 18,27 sec
Low end SATA SSD : 24.08 sec (slower than 660p)
HDD : 45,13 sec
you'll save (MAYBE) about 5 seconds of loadtime, but the price/performance is out of proportion in that scenario, as 5x SSD speed doesn't mean 5x load times. and with the low amount of rewrites, it will last plenty of time..

For my OS and more write intensive tasks, I run faster disks with lower capacity, but higher endurance.

When buying a new SSD consider this..
Long term storage (game libraries, backup, movies library) QLC will do just fine, and real world performance will be almost identical.

For video/foto editing, rendering, CAD etc with lots of writes, a disc with higher endurance will be preferable.. And when done with your project.. Store it on QLC :whistle:

Also.. If benchmarks means the world to you.. Go buy the most blazing fast you can afford, just don't be disappointed if you games don't load faster.

I bought a Micron 5100 ECO 4tb drive almost 2 years ago, new, for $300US. It's a TLC drive, and has both DRAM for cache and a capacitor for power loss. The issue with the QVO now is the same as it was then - there's no value there. I can spend less and get more with other manufacturers.

High price, low endurance, terrible warranty and very poor performance, that's what you get with low end (QLC or DRAMless) SSDs. Decent TLC *with DRAM solutions that perform better, last longer and have better warranties are available at similar prices. The only thing this drive has over them is you can get it in a larger capacity and that simply isn't worth all the drawbacks that come with it.

There's plenty of competition for high performance SSDs now. Samsung can't price gouge the high end the way they used to anymore so they're trying to make it up with overpriced low end junk instead.

For that matter, their price fixing RAM prices has fallen apart too and now this. They must be really desperate to gouge buyers any way they can.

You shouldn't store anything you want to keep on flash memory. It all has a tendency to go bad (bit rot) if not plugged in, in as little as two weeks, you can start to lose your data in corruption.
A HDD is still superior for storage, yet not perfect. Magnetism will deteriorate over time. Long-Life DVD/B-Ray storage is the best currently for consumers.
Certainly NOT Flash RAM for backups/long term storage though. A big no-no.
