It appears that Western Digital is getting ready to expand its budget line of WD Blue SSDs with yet another model, this time a smaller jump from the SN570 to the SN580, compared to the jump in model numbers from the SN550 to the SN570. The drive has passed through the PCI-SIG integrators list and from that information we only know it's a PCIe 4.0 NVMe drive with a four lane interface. However, some retailers have already put up the drive for pre-order and this helps us with a few more details.

For starters, it appears that we're once again looking at drives in the 500 GB to the 2 TB range, although this doesn't mean that WD couldn't launch a 4 TB variant as well, but it seems unlikely. What we also learnt is that these product pages are place holders, as the drives are listed for the same, or higher pricing than the WD Black SN850X, which makes no sense for a budget drive which should be closer to the US$100/€100 mark than the equivalent of twice that. Another European retailer is also listing the current SN570 as being EOL:ed on the 31st of July, suggesting that the SN580 should launch around that date. The same retailer is listing the SN580 as the replacement drive under its part number, which is WDS200T3B0E for the 2 TB SKU.
