There's a few 480GB drives in that range. ADATA SU630/SU635, which is DRAM-less and not great but would be fine for pure storage. Other assorted DRAM-less ones as well. There are some that have DRAM like the Team L5 Lite 3D when it's on sale, there's various "clones" of that drive like the AEGO depending on your brand limitations. These are SATA choices, for NVMe you'd likely drop to 240-256GB with like the Kingston A2000.
