“For Santa Rosa-based systems, the Intel ICH8 supports a SATA bus speed of up to 3.0 Gb\/s. Lenovo made a design decision to prioritize maintaining compatibility with Ultrabay disk drives, which are connected via a SATA-to-PATA conversion chip which could not handle a 3.0 Gb\/s SATA bus speed reliably. Therefore the system was standardized to 1.5 Gb\/s.<\/p>\n

In testing rotating media drives, our measurements show data throughput difference between 1.5 Gb\/s and 3.0 Gb\/s bus speed is less than 5% since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.<\/p>\n

For those customers who choose to purchase an after-market SSD drive capable of SATA bus speeds up to 3.0 Gb\/s, the system will interface with them at 1.5 Gb\/s. Lenovo’s official position is that the Santa Rosa systems are working as designed.<\/p>\n

The Montevina based systems which began shipping last year have direct SATA interfaces for both drive bays and are enabled at a system level for SATA bus speeds of 3.0 Gb\/s performance. Current Lenovo drives have firmware set to 1.5 Gb\/s data rates.<\/p>\n

Exchanging these drives for after-market drives which support SATA bus of 3.0 Gb\/s should provide for the higher data rate at the overall system level. Again, it should be noted that our performance measurements show less than 5% performance improvement between 1.5 Gb\/s and 3.0 Gb\/s SATA bus speeds for rotating drives, since the drive mechanics are the limiting throughput factor, rather than the SATA bus itself.<\/p>\n

After-market SSDs which support SATA bus speed of 3.0 Gb\/s will operate at that bus speed. Depending on the data transfer test method used, your actual data throughput from a 3.0 Gb\/s SATA bus speed should be 220-250 MB\/s and about 90-120MB\/s throughput when running on SATA bus of 1.5 Gb\/s. This is due to the bus signaling used for the SATA bus, as well as overhead for error checking.”
