In the spec sheet it says it has 0mb of cache? Is this true? does it not have dram cache? Also there are many variants of the mx500 out there, how do I know what what i'm getting?

Yes, according to the product specifications, this variant of the Crucial MX500 SSD has 0MB of cache. To ensure you know what variant you are getting, refer to the model number provided in the specifications, which is CT4000MX500SSD1.

Will this fit in my machine? MSI GL Series - 15.6" 144 Hz IPS - Intel Core i9 12th Gen 12900H (2.50GHz) - NVIDIA GeForce RTX 3060 Laptop GPU - 32 GB DDR4 - 1 TB PCIe SSD - Windows 11 Pro 64-bit - Gaming Laptop (Pulse GL66 12UEK-688 )

Open it up and see if it has a 2.5" SATA slot. Most laptops have at least one but I did not see one mentioned on the product page when I looked it up. If it doesn't have an upgrade slot, then it's limited to getting a PCIe card instead of SATA. The only way to include one of these would be to buy a separate cord to hook it up to the USB slots and use it as an external. It would need to be plugged in all the time to use as a permanent storage. I do not recommend this as a simple disconnect can possibly render it unusable.

what is the TBW rating for this drive?

According to the Crucial website, the MX500 4TB model has a 1000 TBW rating.
