The Red Book standard for compact discs specified a bit rate of 153,600 bytes (150 KB) per second, referred to as "1x" CD-ROM speed. Audio was encoded in 16-bit resolution at 44.1 kHz. The original standard specified that each disc could contain up to 99 tracks and store 650 MB (74 minutes). The standard was later amended to allow variances of up to 700 MB (79.8 minutes), though some drives have allowed for usable capacities as high as 750 MB (85 minutes).
The first Adobe product to be available on CD-ROM was the deluxe edition of Adobe Photoshop 2.5, released in November 1992. By version 4, released in 1996, a CD-ROM drive was required and floppy disks were only available upon request. Adobe Creative Suite 2 was the last software suite from Adobe to be shipped on CD-ROM. Creative Suite 3 was released on DVD-ROM in April 2007.
