What this drive is and who it serves

The LG GP65NS78 is a slim external DVD writer that connects through USB 2.0. It reads and writes CDs and DVDs at up to 24x and 8x respectively, and it supports M-DISC media for long-term archival. The silver chassis measures 14.00 mm in height, making it suited for mobile users who need optical capability on a laptop or a compact desktop.

What it upgrades and when the jump matters

It replaces an internal optical drive or an older USB 1.1 unit that cannot write dual-layer discs or M-DISC media. The step up is worthwhile when you need 8x DVD±R DL and 6x DVD-RAM write speeds, buffer under-run prevention, or native compatibility with Windows XP through Windows 10 and Mac OS X 10.7.5 without extra drivers.

Who should buy it and who should not

Buyers who want a lightweight, bus-powered writer for occasional disc authoring, software installation or M-DISC backup will find it fits the brief. It is not for users who require Blu-ray read or write capability, USB 3.0 transfer rates, or a slot-load mechanism.

Questions about this item

How much desk space does the 0.60" x 5.60" x 5.40" drive need?

The slim tray-load unit measures 0.60 inches high, 5.60 inches wide and 5.40 inches deep, so it fits in a small footprint on any flat surface.

Which USB cable and port does the USB 2.0 interface require for installation?

Connect the supplied USB 2.0 cable to any standard USB Type-A port; the drive draws power from the bus so no external adapter is needed.

When should the 0.75 MB buffer under-run prevention cache be checked or the drive replaced?

The embedded cache has no user-serviceable parts; replace the writer only if discs consistently fail to burn or read across multiple media brands.
