2.0 Product Specifications
2.1 Capacity
Table 1. User Addressable Sectors
Intel SSD 525 Series
Unformatted Capacity
(Total User Addressable Sectors in LBA Mode)
30 GB 58,626,288
60 GB 117,231,408
120 GB 234,441,648
180 GB 351,651,888
240 GB 468,862,128
Note: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
LBA count shown represents total user storage capacity and will remain the same throughout the life of the drive.
The total usable capacity of the SSD may be less than the total physical capacity because a small portion of the capacity is
used for NAND flash management and maintenance purposes.
2.2 Performance
The data compression engine in the Intel SSD 525 Series controller optimizes performance based on
the data pattern of the workload.
This section provides both compressible and incompressible Input/Output Operations Per Second
(IOPS) and sustained sequential read and write bandwidth specifications.

Notes:
1. Random 4 KB write performance measured using out-of-box SSD.
2. Performance measured using Iometer* with Queue Depth 32. Measurements are performed on
8 GB of Logical Block Address (LBA) range on a full SSD.
