All my HARD DRIVES are Western Digital and spin at 7200 RPM and have 8MB Cache.
I don't, and never will, use a Laptop to run a Karaoke Show. Unless the Laptop is a "Top-Of-The-Line," Laptops are to "Fickle," never have enough recourses, definitely do not have enough Hard Drive space, the Keyboards and Touch Pads are a Royal Pain, and are too LABOR Intensive to REPAIR. You cannot get an Internal PLEXTOR Laptop Drive...they don't make 'em.
So, in the end, your taking all this time to Set-Up, Tear-Down, and Hook-UP peripherals that a Desktop Computer already has Built-In. Desktops are designed for the average USER to REPAIR, ADD, and REMOVE Components.
Hoster PLAYS the IMPORTED KMA Files that are STORED ON A HARD DRIVE, which would be what is listed in your SONG BOOKS that your Singers will view, write down, and submit to you to PLAY when it's their turn to Sing.
The PLEXTOR will be used when IMPORTING and when a SINGER brings their own CDG Disc and asks you to PLAY a song from their disc when it is their turn to Sing. You were directed to buy a PLEXTOR because PLEXTOR is the PROVEN Drive of CHOICE when it comes to reading a KARAOKE DISC (CDG Disc) correctly.
So, when you are either Importing or adding a Song from a Singer's Disc, you will have a higher probability of successfully Importing and Reading a CDG Disc Properly...So that the Song Trk PLAYS BACK CORRECTLY.
In sustained throughput FireWire is faster than USB 2.0. FireWire, uses a "Peer-to-Peer" architecture in which the peripherals are intelligent and can negotiate bus conflicts to determine which device can best control a data transfer.
Hi-Speed USB 2.0 uses a "Master-Slave" architecture in which the computer handles all arbitration functions and dictates data flow to, from and between the attached peripherals (adding additional system overhead and resulting in slower data flow control)
For all-out sustained throughput, a FireWire external hard drive will provide the best performance. But for convenience and compatibility between multiple computers a USB 2.0 external hard drive would probably be the better choice (since practically every computer has a USB port).
FYI
FireWire 400 (1394a) data transfer rates up to 400Mbps (or 50MB/sec)
FireWire 800 (1394b) data transfer rates up to 800 Mb/s (or 100 MB/sec)
USB 2.0 data transfer rates up to 480Mbps (or 60MB/sec)
