Questions about this item

Does the Lexar NS100 512GB drive ship with a mounting bracket or SATA cable, or do I need to buy them separately?

The drive is supplied as the bare 2.5" SATA III unit; mounting brackets and data cables are not included and must be sourced separately if your system does not already have them.

The NS100 line includes several capacities — why choose the 512GB model over the smaller or larger options?

The 512GB version delivers 550 MBps sequential read speed and 240 TBW endurance in the standard 7 mm height, giving a practical balance of space and longevity for a typical OS plus applications install.

In a real laptop or desktop, what does the quoted 550 MBps sequential read figure actually mean for everyday use?

It represents the peak throughput the SATA III interface can sustain on large, contiguous files; actual boot, app-launch and file-copy speeds will be lower and depend on the host system's controller, RAM and workload mix.
