My Crucial MX500 SATA SSD has been my operating-system drive since early 2019. CrystalDiskInfo recently started showing a caution warning and reports about 9% remaining lifetime. I understand that this doesn't necessarily mean the drive will fail immediately, but I'd rather replace it before it becomes a serious problem. I'm not very experienced with SSD specifications and want to avoid models known for poor reliability or hidden compromises. Another 500GB drive is sufficient, and it needs to be a 2.5-inch SATA SSD because my only M.2 slot is already occupied. I'd like to stay under $200, although I may need to wait a couple of weeks before purchasing. The WD Blue 3D is currently one of my leading options, but I'd appreciate recommendations for dependable alternatives. Should I prioritize a model with TLC NAND and a DRAM cache, or consider moving the OS to an NVMe drive using an available PCIe slot?

You may want to consider an NVMe drive with a PCIe adapter if you have an unused PCIe slot. Good NVMe SSDs can cost less than comparable SATA models and would work well as an OS drive. It’s not necessary if you specifically want to stay with SATA, though—your current interface already limits the maximum speed, so a quality SATA model is perfectly adequate for normal operating-system use.
For a SATA replacement, focus on TLC NAND and preferably an onboard DRAM cache. The older WD Blue 3D, Kingston KC600, Transcend SSD230S, and Samsung 870 EVO are examples of the kind of drives to consider. Be careful with similarly named budget models: some newer versions, such as the WD Blue SA510, don’t have the same specifications as the older WD Blue 3D. Since nearly any decent SATA SSD will hit the interface’s speed limit, reliability and warranty matter more than small performance differences.
WD Blue is a reasonable mainstream choice, while Samsung’s EVO line is also generally well regarded. Avoid assuming that every drive from a brand has the same quality level—budget QLC models such as Samsung QVO or WD Green are lower-end than TLC-based EVO or Blue models. Check the exact model number, NAND type, endurance rating, and whether it includes DRAM before buying.
Before replacing it, check the drive’s total host writes or TBW and make sure you have a current backup. A remaining-life warning is a good reason to plan a replacement, but it doesn’t provide an exact failure countdown. Move important files elsewhere and clone or reinstall the OS when you switch drives.
That distinction between product lines is helpful. I’ll make sure I’m checking the exact model rather than relying only on the brand name.
