J''utilise this SSD a few months. I just bought the second, is to say how satisfied I am with my first purchase. Its 256 GB memory used to store a lot of photos ... heavy or anything you like. For ultimate reliability, we will see in a few years, for no one is soothsayer. Meanwhile, that little, tiny external SSD is perfect. It has the dimensions of a credit card, it is fast (SSD combined with USB 3, I did not measure to the nearest second, but it moves). It is especially useful to keep with you the data that is held most in travel for example, stored in any portfolio. I bought my first external drive there is a good ten years (it still works flawlessly). For a 250GB capacity, this object soon become Neanderthal, the size and weight of a toaster.
