T400S SSD full speed?

[pmeinl]

Does the T400S deliver the full speed of SSDs?
When used
- as Primary drive (I believe yes)
- as drive in ultrabay
- on eSATA port
- on eSATA port of the Mini Dock (Plus Series 3)

I am asking this, because my X61T limits the sequential read transfer rate of the X25-M SSD to 110 MB/sec (the SSD is able to deliver 220 MB/sec), limits the transfer rate of PCMCIA eSATA to below USB speed and cripples the speed of HDs in the docking station too.

The reason why your X61 limits the speed of your drives is because it only supports SATA-150. The theoretical maximum speed you'll see on anything connected to your computer via a SATA interface is 150MB/s.

I don't know what type of PCMCIA the X61 uses, but the older version is 16-bit and limited to around 20MB/sec.

T400s supports SATA-300, so yes, it should deliver the full speed of SSDs.

They limited the T61, R61 and X61 to SATA 1.6GBs speeds, though the chipset supports 3.0GBs due to supposed unstable data streams when on the PATA to SATA bridge in the UltraBay. The T400 will support support drives like the X25-M or Vertex at full speed.

No issue with T400s here. I got 128GB Samsung SSD (Lenovo option), and according to CrystalDiskMark have 204 MB/s Read and 183 MB/s Write.

In primary, it should be full speed.
In ultrabay, I'm not sure, but I think the bridge slows the transfer down a bit
Through eSATA port, you'll get about 120mb max, that's just the way it is.
