9M.2 NGFF PCIe 4.0 Internal Solid State Drive 4TB 990Pro High Speed Up to 7400MB/s SSD for Laptop and Desktop PC

This appears to be a decent deal for a 4TB PCIe 4.0 NVMe SSD, especially if the "990Pro" branding indicates a reputable model. However, the original price is not specified, making it difficult to assess the exact discount. AliExpress can sometimes have variable quality and shipping times, so buyers should exercise caution.
