Chapter 3: SDLT 600 Tape Drive Specifications

3.1.5Storage Capacity

Table 3-5provides native and compressed capacity ranges for the Super DLTtape II data cartridge:

Table 3-5.SDLT 600 Tape Drive Storage Capacity

Mode	Capacity

Native Storage Capacity	300 GB

Compressed Storage Capacity	600 GB (2:1 compression ratio)

In accordance with industry practice, a typical compression ratio of 2:1 is quoted. The redundancy and type of data files being written determine the actual compression ratios achieved.

3.1.6Data Integrity

SDLT 600 tape drive data transfer errors are extremely rare; Table 3-6shows data integrity for the overall SDLT 600 tape drive system.

Table 3-6.Data Transfer Error Rates

Error Type	Frequency

Detected, Recoverable (ECC) READ	< 1 error in 10	6	bytes read
	< 1 error in 10		bytes read

Detected, Unrecoverable READ	< 1 error in 1017 bits read

Undetected READ	< 1 error in 1027 bits read

Rewrite of Data	< 1 per 106 bytes written
