3. Product Specifications
3.1 Capacity
Capacity specification of SDM5-M is available as shown in Table 3-1. It lists the specific capacity and the
default numbers of heads, sectors and cylinders for each product line.
Table 3-1: Capacity specifications
Capacity Total bytes* Cylinders Heads Sectors Max LBA
1 GB 1,011,032,064 1,959 16 63 1,974,672
2 GB 2,011,226,112 3,897 16 63 3,928,176
4 GB 4,011,614,208 7,773 16 63 7,835,184
8 GB 8,012,390,400 15,525 16 63 15,649,200
16 GB 16,013,942,784 16,383 16 63 31,277,232
32 GB 32,017,047,552 16,383 16 63 62,533,296
*Display of total bytes varies from file systems, which means not all of the bytes can be used for storage.
**Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of the
device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small portion
of the capacity is reserved for device maintenance usages.
