3.0 Product Specifications
This section provides details on the Intel SSD 310 Series product specifications.
3.1 Capacity
Notes: 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.
1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
3.2 Performance
Notes:
1. Performance measured using Iometer* with queue depth set to 32; Measurements are performed on 8 GB of LBA range.
Write Cache enabled.
2. Performance measured using Iometer with queue depth equal to 32.
Sequential performance measurements assume 1 MB/sec = 1,048,576 bytes/sec.
3. Device measured using Iometer; Read/Write latency measured on sequential 4 K transfers with queue depth set to 1.
Write Cache Enabled.
Power On To Ready time measured from power rail rising edge to the first DRDY issued from the drive.
