Good performance for entry-level SSD. I wanted to change the hard disk on an old laptop to give it a bit of force: it works perfectly. For my use case, I regret that it is not only provided a small windows 7 optimization software (disabling indexing functions, prefetch, ...). I installed "SSD Fresh" to overcome that. [For comparison the Samsung drive come with the software "Magician" that performs these operations] I left a complete system installation. Those who want to perform an installation by duplicating an existing system also regret the absence of software to do this ... [I'm not sure that Samsung still do, but at a time Samsung delivered a suite of replication and backup with its SSD]. For my use case and for the price it is a very good product.
