I hope you take regular backups.

Throwaway build used for testing. But, yes, I back up to two separate iSCSI NAS devices and cloud on my important builds. I also wear my seatbelt every time I get into one of my cars :/

What bandwidth are you getting on that 4 disk raid 0?

Tops out at 16GB/s reads and 9GB/s writes on sequential 16 queue depth. A little disappointing, to be honest since the drives themselves do about 5GB/s/4.4GB/s.

Build is a 3900XT on Asrock Phantom Gaming 4 AX X570, 128gb RAM. I suspect on a VROC or Threadripper the performance would be better given PCIe lane limitations on X570.

Is the one with heatsink significantly big that I need to check my laptop to see if it'll fit? Thanks

There's no way the heatsink version will fit in a laptop, it's pretty huge compared to the size of the drive.

Out of curiosity, what type of use case are you working on that needs that kind of IO and still warrants this risk of RAID 0? Some sort of cache in front of a larger storage?

I have zero legitimate use case other than benchmarking and bragging rights. Complete waste of money.

Is it odd that I haven't seen any NVMe deals over the last few months? there were tons of deals this past summer! anyway, picked up 2 of the 1TB with heatsink, Thanks OP!

The floor fell out of the SSD market last year and a lot of makers ran emergency price drops to stay competitive. All of the factors that caused that drop are either fixed now or are on track to be meaning SSD prices will stabilize or even rise.

My MB covers all my NvME drive. No need to get a NvMe with heatsink right?

Naive question here, does the MB have to support Gen4 for this to work? Or are Gen4 sticks like this backward compatible?

That said if my MB only supports Gen3, is there any point to getting a Gen4 SSD for it?

What is the main benefits for Gen4? Speed?

Sorry I know I can google this but taking the easy route

Is the raid card pci-e 4.0 x16?

This will work in a PCIE 3.0 motherboard, but there's no point in it. Just get a much cheaper 3.0 m.2. Benefit of Gen 2 is speed, but only the newest drives really take advantage of it, and even so, most users don't need the extra speed. a decent 3.0 nvme drive is plenty for 99% of people.

No it won't work in a PS5 since they have not activated the expansion slot yet and we have no ETA on that. Zero reason to buy one until they do and we know which ones will work.

^This is 100% correct. The PS5 will literally go into a shutdown/reboot loop (~30 second countdown timer after bootup) until you remove the drive.

Just curious.... what is your NAS is serving that would require this level (NVME ) of read-write speed... and are you running 10g fiber from the NAS clients to actually stress the NAS.... I have 4 PCs (HPC ) on 10g Fiber connecting to a Open Media vault NAS with 6 drive (14tb) raid 10 .... I discovered my 7200rpm NAS drives were the choke point when all of the PCs were publishing (writing ) extremely large files (video editing ) to the NAS

I think I worded that poorly. The quad NVME setup was on a throwaway OS installation done for the sole purpose of benchmarking. The drives have since been repurposed as boot drives in other systems.

I only do backups to the iSCSI NAS over gigabit. I don't use them for any other purpose. Drives are Hitachi Coolspin 5900. Throughput isn't a concern since their only purpose is for backups of my desktops.

Hm... this or the SN750 for $130? I'm looking for reliability/longevity and low power consumption (laptop has a small battery), but can't seem to find any idle power consumption on this one. But TBW look great, especially compared to the measly 75 tbw of the 250 gb optane trash that's in it right now, which I already used 5% of in barely 2 months. But I knew that, my plan was to swap it anyway. I guess I'm looking for something that sips a little power as possible while idle...
