My Crucial MX500 SATA SSD has been my operating-system drive since early 2019. CrystalDiskInfo recently reported a caution status and showed about 9% of its rated lifespan remaining. I know that doesn't necessarily mean the drive is about to fail immediately, but I'd rather replace it before there's a serious problem. I'm not very familiar with SSD reliability and want to avoid models with known weaknesses or misleading specifications. Another 500GB drive would be sufficient, and it needs to be SATA because my only M.2 slot is already occupied. I'd like to stay below $200, although I may need to wait a couple of weeks before buying. The WD Blue 3D is currently my leading choice, but I'd appreciate recommendations for dependable alternatives and any advice about interpreting the remaining-life warning.

It would also be useful to check the drive’s total host writes or TBW. The percentage shown by the monitoring software is an endurance estimate, not a countdown to failure, and a drive can continue working beyond that point. Still, treat the warning as a good reason to maintain a current backup and replace the SSD when convenient rather than waiting for symptoms.
Before settling on SATA, check whether you have an unused PCIe slot. An inexpensive PCIe-to-M.2 adapter could let you install an NVMe drive and may offer better value than a similarly well-built SATA SSD. It won’t make the operating system feel dramatically faster in everyday use, but NVMe drives are often cheaper because SATA is now mostly the budget segment.
The WD Blue 3D is a sensible choice, and Samsung’s mainstream EVO line is another dependable option. You don’t need to chase maximum performance since any decent SATA SSD will be limited by the interface. Avoid assuming that every drive from a major brand has the same quality, though: budget QLC models such as Samsung QVO or WD Green are a step down from mainstream TLC drives like the WD Blue and Samsung EVO.
For a SATA boot drive, I’d prioritize TLC NAND and a DRAM cache rather than benchmark numbers. Older WD Blue models, the Transcend SSD230S, Kingston KC600, and Samsung 870 EVO fit that general category. Check the exact model number before buying, because newer products with similar names—such as the WD Blue SA510—may use a different design and not include DRAM.
