ended or Low Voltage differential, 3.5"FH
*1, *2 This is assuming 2:1 Compression ratio.
The degree of data compression attained while recording data varies according to system environment and data
type.
Note: The SDT-10000/SDT-11000 drive uses data compression to achieve high capacity and high transfer rates. Ac-
tual capacity and transfer rate depends on the source file type.
Note: The capacity ratings listed above are based on a 150 meter DDS-4 tape cassette.
The Sony SDT-10000/SDT-11000 drive is a high capacity data storage device using 4 mm DAT (Digital Audio Tape)
technology. The SDT-10000/SDT-11000 drive achieves high data reliability through read-after-write, an additional
level of Error Correction Code, and other features.
The Sony SDT-10000/SDT-11000 drive stores data on tape using a standard format called DDS (Digital Data Storage),
DDS-DC, DDS-2, DDS-3 and DDS-4. This format is used by numerous other DDS tape drive manufacturers, providing
a broad range of compatible tape drives.
The Sony SDT-10000/SDT-11000 is fully READ and WRITE compatible with the DDS-4, DDS-3, DDS-2, DDS and
DDS-DC format tapes.

2. SPECIFICATION
2. 3 PERFORMANCE SPECIFICATION
The data capacity, data transfer rate and data reliability specifications in this chapter require the media to conform to the
DDS-4 Media Specification and also require the drive and media to remain within their respective operating and non-
operating environmental specifications. The specifications below also assume that the C3 ECC frame is generated on
writing and used as necessary on reading, and further assumes that read-after-write rewrites are used as necessary on
writing.
2. 3. 1 Data Capacity
The native (uncompressed) capacities of different length cartridges are as follows. Note that 60 m and 90 m cartridges
are automatically written in DDS-1 format, only 120 m cartridges are written in DDS-2 format, and only 125 m car-
tridges are written in DDS-3 format, and only 150 m cartridges are written in DDS-4 format
Length Format Native Capacity
60 m DDS-1 1.3 GB typical
90 m DDS-1 2.0 GB typical
120 m DDS-2 4.0 GB typical
125 m DDS-3 12.0 GB typical
150 m DDS-4 20.0 GB typical
The SDT-10000/SDT-11000 includes a data compression capability. When data compression is enabled that the drive
capacity can increase typically twice. The efficiency of the data compression depends on the actual data that is being
compressed and cannot be predicted precisely prior to compression.

DDS-4 2360 KB/S 4720 KB/S
2. 3. 2 Data Transfer Rate
2. 3. 2. 1 Sustained Data Transfer Rate To and From Tape
The sustained transfer rates to and from the tape are as follows. For this sustained rate to be achieved, the drive must be
streaming. There may be some dependency on the host for this to be achieved.
*1 This is assuming 2:1 Compression ratio.
The degree of data compression attained while recording data varies according to system environment and data type.
2. 3. 2. 2 Burst Data Transfer Rate To and From the SCSI Bus
The SDT-10000/SDT-11000 will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of
14 megabytes per second, using WIDE SCSI asynchronous transfers and 40 megabytes per second, using WIDE SCSI
synchronous transfers.
2. 3. 3 Initialize Time
Initialize Time means the period from the time the drive is powered on to the time when the drive is ready and waiting
for a SCSI command such as INQUIRY or TEST UNIT READY.
Initialize Time is less than 1 seconds.
Note: The drive will respond with BUSY status until the completion of the Initialize Time.
Note: The Initialize Time does not include the time necessary for drive diagnostics to complete and the drive to become
ready for tape insertion.

SONY SDT-10000/SDT-11000 DDS Tape Drive
2. SPECIFICATION
2. 3. 4 Load Time
Load Time means the period from the time when the operator inserts a cassette into the drive to the time when the drive
is ready.
Load Time is less than 24 seconds (for a single partition tape).
2. 3. 5 Rewind Time
Rewind Time means the period from the beginning to the end of rewinding sequence. This value depends on the tape
length and the position of the head along the tape.
Rewind Time is less than 80 seconds, when a 150 meter tape is loaded.
2. 3. 6 Search Time
Search Time means the period for the drive to find the position that is required by a command. This time also depends
on the tape length and the position of the head along the tape.
Search Time is less than 90 seconds, when a 150 meter tape is loaded.
2. 3. 7 Unload Time
Unload Time means the period from the beginning of the unload sequence caused by Unload Command or Eject button
to the time when a cassette is ejected from the slot.
Unload Time does not include Rewind time.
Unload Time is less than 20 seconds (for a single partition tape).
2. 3. 8 Error Rate
The uncorrectable bit error rate is expected to be less than 10-15. For further details, refer to “Designing a Data Storage
Format for Digital Audio Tape (DAT)”, produced by the DDS Manufacturers Group.
2. 3. 9 Retry Limits on Rewrites
For Read-After-Write error correction, each frame can be rewritten up to a maximum of 255 times giving 256 writes of
the frame. With N-Group writing, where every group is written a fixed number of times, the upper limit is 8.
N-Group writing is not supported by DDS-3 and DDS-4.
2. 3. 10 Definition of Failure
A failure is defined as any permanent malfunction of the drive that prevents the user from retrieving data from tape. This
includes failure to power up, failure to unload or eject a cassette, or failure to write and read data to and from the tape,
providing that both the drive and tape are being used within specification.
Faults are not considered failures when they are related to operator error, mishandling and abuse, system-related faults
(cabling problems, unsupported systems, operating software, and so on), no trouble found, and transportation damage.
2. 3. 11 Mean Time Between Failures
The Mean Time Between Failures (MTBF) for the SDT-10000/SDT-11000 is 250,000 power-on hours, assuming a duty
cycle of 40%, where:
12.5% is assumed as a typical usage level.
2. 3. 12 Mean Time To Repair
The Mean Time To Repair (MTTR) of the SDT-10000/SDT-11000 is 30 minutes. Since at the field level the entire drive
is considered a Field Replaceable Unit (FRU) the time to replace the drive with a new one is less that 30 minutes.
