Despite an apparently good piece of hardware MP500 represents, CORSAIR didn't "Force" themselves to develop the software part of things. The "so acclaimed" and necessary SSD Toolbox is in fact an old and rusty "Emptybox", at least for this new series...
They are advertising on the product's page about SSD Toolbox support for S.M.A.R.T, over-provisioning, firmware update etc. and it is a HUGE LIE! How can they let us buy their products without providing not only the necessary support but the promised one... This is very unusual for a company like this... It seems like they didn't update this app since 2013!!!
So, if an ordinary extension-utility like this doesn't yet support the involved hardware to fully-enable it's features and extend it's life, how can we expect anything else from CORSAIR... ?
