Purchased on February 19, 2020 for 16E. It is necessary to have a CD/DVD drive in every desktop computer (from the old days when it was very common until now (2016 ~ 2020+) in an era where CD/DVD is not used and has died for most people, it is still necessary and you never know when you will need it to install software (drivers) or games that are from a physical store (not through the internet) and are provided on DVDs, to watch movies on DVD, but also to burn CDs/DVDs with songs and movies for old televisions (or for those who prefer DVDs over USB) and for the car. CDs have the advantage over USB (where you usually put .mp3 files with a max bit-rate of 320 kbps), CDs can write .flac files with ultra-high sound quality that can reach up to 1400 kbps and another advantage is that you can write the names of the songs on them with a marker and not get lost searching for them on a large USB that the system organizes randomly. Professional photographers still give DVDs to people who want this medium or are technologically 10 ~ 15 ~ 20 years behind (even if they only reach 576p in resolution) or don't know about USB, so it is a must-have for those who know in order to convert these DVDs to USB sticks or hard drives. CD/DVD discs, if they do not have scratches and are stored in a case, are much more reliable for backing up important data over time compared to USBs and hard drives, whose FLASH/NAND memory can be erased or fail over time, and the disk plates of hard drives can be demagnetized at a rate of 1/1000 when they are idle. CD/DVD discs can still work even if they get wet if you wipe them off. The disadvantages of CD/DVD discs are more common and that's why they are not widely used today (slow speeds, risk of scratching or breaking, relatively large size compared to capacity, need to buy new ones for each recording except for RW types that have a certain number of writes before the quality decreases). For the LG GH24NSD1 we have: -> It has very good reading and writing speeds on discs (x48 CD read/write, x16 DVD read, x24 write DVD/re-write CD, x8 ~ x6 re-write DVD+R / -R), it can write up to x24 on a DVD which is not available in the market, DVDs in the market are max x16 so you understand that it will not reach the limits of DVD writing. -> It has a groove on its tray for small DVDs that were used in old SONY camcorders. -> It has a new technology (M-Disc) to write data more intensely/higher quality so that it can be better preserved over time compared to conventional discs (the laser engraves the microscopic pits on the disc better for better data recording). -> It is from LG and it is a good brand. -> Currently, it has successfully written 5 DVDs and 3 CDs (when writing at max speed, it makes noise as it is logical to do), and it plays movies with minimal to no noise.

Update October 1st, 2020 -> It works reliably on both CDs and DVDs, but because some new mid-tower computer cases have glass surfaces, RGB lights, and a side slot for liquid cooling, this is a reason not to prefer it because it doesn't have a place in the computer case to install it and connect to an external CD/DVD unit via USB. However, an internal unit like this has greater reliability and speed in disc recording. If you have another case with a 5.25" slot, it fits perfectly in your computer.

I will reevaluate it after some time if I see something.
