ML350p Gen8 - Sata motherboard connector speeds

Hello everyone,

There are 3 sata connectors on the server motherboard (one used by optical drive).   Can someone tell me if they are Sata II or Sata III???

I was disappointed to learn the p420i runs at Sata II with Sata drives attached instead of SAS.

TIA

Re: ML350p Gen8 - Sata motherboard connector speeds

Hi,

As for my understanding embedded SATA ports are designated for the optical drives and it runs at SATA 1.5 speed.

also

HP Smart Array P420i Controller-Specification

Disk Drive and Enclosure
6 Gb/s SAS (Serial Attached SCSI)
Interface - Transfer rate
3 Gb/s SATA (Serial ATA)

 

FYI,

SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s, is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s.

SATA II
 (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.

SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.

I once put an SSD on a Gen8 optical drive SATA port.  It silently corrupted quite a bit of data.

Not sure if it was just a faulty port or if having a high speed drive on this port is outside of HPE's design and test parameters.  Either way, be careful.

My ATTO benchmark speeds on the SATA ports confirm a maximum speed of 150 MB/s.
