Western Digital Quietly Launches the SN5000 Budget NVMe SSD
Western Digital has released a new budget friendly SSD that got a serious jump in model number, since the company decided to call it the SN5000. Its predecessor is the SN580 launched just under a year ago and price wise, it's the better option of the two. The new SN5000 uses the same BiCS 5 TLC NAND as the SN580 on the 500 GB to the 2 TB SKU, but according to Anandtech, the 4 TB uses BiCS 6 QLC NAND. The SN5000 is still a PCIe 4.0 x4 NVMe drive, but the overall performance has been significantly improved. If we use the 1 TB SKU for comparison, then the sequential read speeds have gone up by 1 GB/s from 4150 MB/s to 5150 MB/s. The sequential write speed is up 750 MB/s from 4150 MB/s to 4900 MB/s.
As for random performance, the read IOPS are up from 600K IOPS to 730K IOPS and the write IOPS are up slightly from 750K to 770K. The 4 TB QLC SKU is said to deliver even better performance with the exception of the random read IOPS. The 1 TB SKU is said to have a write endurance of 600 TBW, but the 4 TB SKU only offers 1200 TBW. That's 0.33 drive writes per day (DWPD) for the 1 TB SKU vs. 0.16 DWPD for the 4 TB SKU, showing the weakness of the QLC NAND. A new feature for the SN5000 series compared to previous WD Blue NVMe drives is support for TGC Pyrite 2.01 encryption. The WD SN5000-series starts at US$70 for the 500 GB model, going up to US$80 for 1 TB, US$140 for 2 TB and topping out at US$280 for the 4 TB model. WD only seems to have the 500 GB model in stock, with all the others being available in 3-4 weeks time. All SKUs come with a five year warranty.

Also to create even more confusion, in the WD store on Amazon has a Gen 3 SN500 listing that is still up
Companies typically issue press releases to announce their products, build some hype, and there's lots of marketing fluff injected.
Sometimes the entire release is nothing but fluff and BS (which is where you usually see me or others here putting them on blast).Not even, a quiet launch is more like crop dusting a fart down a hallway.
People will find out about it, but not because you told them so.
MaxioTech might have a solution for you though, but if any SSD makers will deliver based on what the controllers support, I don't know.
