    This item is perfect for someone who used to struggle with a C drive with less than 200gbs, after I switched my C drive to this SSD my struggles of my processor being held back due to lack of space was nullified. after merging of my 1 tb drive and my previous hard drive into this SSD I still have so much space, it future proofs my projects that usually take so much space, like my code,videos and images. And no problems to note of, the API provided once you instal the SSD is also helpful for knowing just how much storage and how well it operates. I'm very satisfied with my purchase!

    the read and write speeds on this drive are great, it installed easy. and I've had no issues with it yet... that being said... make sure you watch the prices, the market fluctuation is crazy, i've seen it as high as 400 and as low as 200 all between june 2023 to november 2023 keep an eye on samsung 990 pro and the crucial t500. they all seem to be competing for the same spot
