Important notes
Processor speed indicates the internal clock speed of the microprocessor; other
factors also affect application performance.
CD or DVD drive speed is the variable read rate. Actual speeds vary and are often
less than the possible maximum.
When referring to processor storage, real and virtual storage, or channel volume,
KB stands for 1024 bytes, MB stands for 1,048,576 bytes, and GB stands for
1,073,741,824 bytes.
When referring to hard disk drive capacity or communications volume, MB stands
for 1,000,000 bytes, and GB stands for 1,000,000,000 bytes. Total user-accessible
capacity can vary depending on operating environments.
Maximum internal hard disk drive capacities assume the replacement of any
standard hard disk drives and population of all hard disk drive bays with the
largest currently supported drives that are available from IBM.
Maximum memory might require replacement of the standard memory with an
optional memory module.
Each solid-state memory cell has an intrinsic, finite number of write cycles that the
cell can incur. Therefore, a solid-state device has a maximum number of write
cycles that it can be subjected to, expressed as “total bytes written” (TBW). A
device that has exceeded this limit might fail to respond to system-generated
commands or might be incapable of being written to. IBM is not responsible for
replacement of a device that has exceeded its maximum guaranteed number of
program/erase cycles, as documented in the Official Published Specifications for
the device.
