1.2 Models

The Ultrastar XP SSA disk drive is available in various models as shown below.

The Ultrastar XP SSA data storage capacities vary as a function of model and user block size. The emerging industry trend is capacity points in multiples of 1.08GB (i.e. 1.08/2.16/4.32) at a block size of 512 bytes. Future IBM products will plan to provide capacities that are consistent with this trend. Users that choose to make full use of the Ultrastar XP SSA drive capacity above the standard capacity points may not find equivalent capacity breakpoints in future products.

Model #	Capacity G B (@512 Byte)	F o r m Factor	Connector Type

C1B	1.12	Brick On Sled Carrier	128-pin H P C

C1C	1.12	3.5-inch Small F F	38-pin Unitized

C2B	2.25	Brick On Sled carrier	128-pin H P C

C2C	2.25	3.5-inch Small F F	38-pin Unitized

C4B	4.51	Brick On Sled carrier	128-pin H P C

C4C	4.51	3.5-inch Small F F	38-pin Unitized

Note: CxB models (C1B, C2B, and C4B) include a D C / D C converter, activity and check indicators.

Note: Please refer to section 2.1.1, “Capacity Equations” onpage 13 for exact capacities based on user block size.
