Because of this, all drives are essentially interchangeable. CD-ROM drives are available either as stand-alone or built-in units with a variety of interfaces (connections) and access times. |
| Drives are usually described as being times some number, ×4 for example. This refers to how much faster the disc is moving past the read head in comparison to a standard music CD. Modern drives are sometimes quoted as being ×44 or higher. However, this will only be true for data retrieved from certain areas of the disc surface, not the whole disc. |
