Questions about this item

Does the MZ-7KE2T0BW include a mounting bracket or cables, or must they be purchased separately?

The drive is supplied as the bare 2.5 inch unit; mounting brackets and SATA data or power cables are not included and must be sourced separately.

How do I decide between the 2 TB capacity and smaller sizes in the 850 PRO line?

Choose the 2 TB model when you need maximum space for large media libraries or multiple operating systems; smaller capacities cost less but offer proportionally less storage.

What does the 550 MBps sequential read figure mean once the SSD is installed in a laptop?

It represents the peak throughput the controller can sustain on a SATA 600 link; real-world speeds will be lower due to file-system overhead, thermal limits and the host system's own bottlenecks.
