This page reports specifications for the 512 GB variant. With the rest of the system, the Intel 545s interfaces using a SATA 6 Gbps connection. The SSD controller is the SM2259H from Silicon Motion, a DRAM cache chip is available. Intel has installed 64-layer TLC NAND flash on the 545s, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The cache is sized at 6 GB. The 545s is rated for sequential read speeds of up to 550 MB/s and 500 MB/s write; random IOPS reach up to 75K for reads and 85K for writes.
