Steam deck compatible?

NO. For Steam Deck, you need SSD M.2 2230 such as B09V4PBQRF (1TB capacity) and B09YYGJV7B (1TB capacity).

i have a 2011 hp usdt with a mini pci express x 1 slot available. is this the correct ssd to use? the mini sata slot has a 2042 m-sata drive.

No, this will not work in your HP laptop. mSATA is different from M.2 NVMe PCIe.

Will this work with lenovo x250 in the wlan card slot or is there any way i can use msata ssd in the same slot?

No. You need M.2 SATA (Not NVMe PCIe).
