Needless to revisit the excellent service provided to customers by Amazon, whether in control, monitoring and delivery faster (thank you Amazon Prime). This SSD has taken the place of a large 3''5 on my Dell XPS One 2710. Easy to install, easy update via the crucial website (Windows 8); if it is not the best in all areas (in relation to the 840 Pro from Samsung), it must be remembered that his MLC memory and embedded technology make him an excellent daily SSD. On the life, if all goes well, it should be a much better level than Samsung 840 Evo example that uses the TLC memory and whose reliability in the long term is far from having been proven . The only small problem concerns the tedious migration process which, if we do not have adequate external hardware and software that works well (they are rare) Windows 8 / 8.1 and supports manufacturers partitions, can often lead for disaster if we do not backup their data also! You never thank enough computer manufacturers who deliver more than CD, USB key OS / drivers that prevent the system backup DVD to reinstall them on another hard disk other than the one provided with the machine. A peak when we think we have created in the event of failure of this disc. This requires, for me, a complete reinstallation of the system software, drivers, software and data ... Some of my hours in a beautiful day ;-) Oh I forgot, for the happy owners of Windows 8 / 8.1, a hardware change can lead to disabling the Windows license, which must then activate by phone, if all goes well. Honest users find it very painful Mr. MICROSOFT!
