These drives slow way down as soon as their cache is full. Lots of videos on this. Depending on your use case, this may be a problem.

To add specific detail to this, the 4TB has a 78GB SLC cache. It'll do 446 MB/s writes while the cache has room, then drop down to 164 MB/s for the remainder of the sustained write.

Presume the cache clears once the write or read has completed? Maybe no good for loading huge game textures or something but seems like plenty for 95% of average use cases.

The cache will clear at 164 MB/s, which is the throughout of the drive's QLC. For example, if the writes to the drive stop for one second after running for a long time (cache full) and then start again, the drive will be able to absorb 164MB of more data at the SLC rate of 446 MB/s.

If you use it as a game or storage drive for write occasional stuff, I think it'll do fine. The people hating on it blindly are poorly informed imo as most consumers do not write tons of files.

Read speeds are acceptable and this price certainly is quite nice for 4tb ssd of anything. Is it gonna be the fastest ssd? No but its also sata and your looking at max, couple to tens of seconds of difference in games which isn't a bad tradeoff.

If you have non critical write workloads, samsung software will let you use a portion of RAM as cache.

Any idea if the Samsung software will let you use RAM as cache even if you set these two drives up in RAID 0?

I have 64GB of RAM and am thinking of replacing one 8TB 3.5" drive with two of these QVO 4TBs in RAID 0.

You can leave that to the operating system - it will automatically use free memory for disk cache.

Dude, if you really want speed and size, you might want to pass on this. Get a U.2 drive or a raid card for nvme. That stuff costs $$$ though.

Windows non-server editions limit how much write cache is allocated for data safety reasons.

Yeah this is $600 for 8TB - I'm going to get nowhere near that with NVMe. Also an ITX setup so I have no more PCIe slots or NVMe slots.

This is simply incorrect. Samsung's Rapid mode allocates a lot more RAM as disk cache than Windows does automatically. All I'm wondering is if Rapid mode works if the QVO drives are in RAID 0.

Is there even any other good alternative for a 4TB SSD in the market? (No NVME)
I have a WD Blue 4TB TLC drive (Model WDS400T2B0A) that seems fine.

Samsung's Rapid Cache will use the lower of 25% of system memory or 1GB (source [pugetsystems.com]). If you want to use more than the 1GB Samsung limit and the 10% non-server Windows provides (which would be ~6GB in your case) then try PrimoCache [romexsoftware.com] - free trial and $30 to buy.

I have this with one of my 2TB NVMe drives. Yea it's blazingly fast for the first 500MB butr then it slows down to like 25Mbyte/s for the rest. This is a major problem when you're trying to copy a TB.
