Drive overview
Beige drive
Black drive
LG GSA-H50N is a Super Multi DVD burner capable of reading and writing DVD+R/RW/DL, DVD-R/RW/DL, DVD-RAM, and CD-R/RW formats.
"Super Multi" was coined by LG in 2003 and is an informal term describing DVD burners compatible with all existing DVD and CD formats.
Prior to 2003, DVD-RAM and DVD+R/DVD-R drives were separate devices. LG Electronics was the first company to release a drive that supported all three DVD formats. Several companies have since followed this strategy, making "multi" and "super multi" commonly used terms.
Drive specifications
LG GSA-H50N specifications on LG website list the following:
LG GSA-H50N uses the 66.7 MB/s ATAPI-5 ATA Packet interface, also known as Ultra ATA/66 or Ultra DMA Mode 4.
ATAPI-5 specification requires using an 80-wire EIDE cable. 80-wire EIDE cables have the same 40-pin connectors as 40-wire cables, but they can be easily recognized by higher wire density in the cable and differently colored (blue, grey, and black) connectors.
Drive appearance
The drive we are reviewing is a bulk-package (OEM), black drive. LG GSA-H50N is also available in beige color.
The front panel has the typical LG look common to all recent LG drives, with a slightly protruding, contoured tray. The silver-colored company logo and various DVD, CD, and Super Multi logos indicating drive functionality are symmetrically arranged on the tray. The rest of the panel houses an eject button, an emergency eject hole, and a bright, round, green activity LED:

The top cover of the drive has four deep indentations that redirect airflow naturally created by fast disc rotation and also help reduce disc resonance and chassis noise at high speeds.
The sticker lists the drive model (GSA-H50N), serial number, firmware revision (1.00), manufacturing date (February 2007) and country (China), power ratings, and various regulatory compliance logos and notices:

Left, right, and bottom sides of the drive provide standard mounting holes for case or rail screws and attachment points for the removable front panel:

The rear side houses the standard 4-pin DC power connector, a 40-pin EIDE/ATA connector, jumper pins that set the drive to IDE master, slave, or cable-select mode, and a four-pin analog audio connector:

The inside of the drive is the typical layout with a small PCB (printed circuit board) in the back:

The drive's electronics is based on a Panasonic chipset, MN103SC7GRT1, also used in LG GSA-H55N and LG GSA-H55L:

Introduction
One thing I would advise against is using any LG drive for TRT. Those drives have no problems with extremely poor burns. I have had a severely degraded Ritek G05 that would not read at all in any of my liteons, I put it in my LG and it did not slow down once during the rip. I've noticed this on a number of poorly burnt discs in the past and I have two LG drives to confirm that they are very good readers, too good when it comes to TRT.

Many things besides the quality of the disc can go wrong at high reading speeds. 16x DVD speeds mean interpreting 56 meters/180 feet per second of track covered with microscopic bumps. It makes me think of reading highway signs written in Braille - at supersonic speeds
The whole thing is a bit of a black art... a reading test can show a hint of a problem where the quality test sees none, and vice versa. The best we can do is to pick one reading drive for a review and stick with it until there is an apparent contradiction between a quality test and a reading test, as was the case here.
