Does w530 msata support 6Gbps SATA III? [ Edited ]

[Sonymor]

Hi everyone, I know W520 mSATA support 3 Gbps connection. but by launching new mSATAIII SSDs I hope W530 with Ivy Bridge and QM77 chipset suports 6 Gbps connection.

thanks for any Idea or references abaut it?

Nope, the QM77 only supports 2 * SATA-3 (6Gbps) ports, the other 4 SATA channels it has are limited to SATA-2 (3Gbps) speeds:

The two SATA-3 ports were used in the W530/T530/T430 for the internal hard-drive bay and the UltraBay, the mSATA port is only SATA-2.

thanks, you mean it does not use PCI-E bandwidth for mSATA?

mSATA on the W520 and W530 are on the SATAII spec.

mSATA does not use PCI-Express despite being in the mini-PCI-Express form factor.

When plugged into a compatible port mSATA causes the port to change it's mode to SATA-based signalling instead of PCI-Express; this is why mSATA cards only work in specific slots on laptops instead of in any/all mini-PCI-Express slots.

Nope I suggest you get ssd on main bay and put 2nd hard drive on ultrabay

Thank you all for Convincing replys, I do not believe it is good idea to use mSATA for WWAN, So what about the best mSATA in best performance/price?

Since my general recommendation for a normal SSD is the Samsung 830, my recommendation for an mSATA SSD is the Samsung PM830. The PM830 is the Samsung 830 in a mSATA format. It is also somewhat future-proof in the sense that it is capable of SATA III speeds.

The Samsung PM830 (mSata card) is not yet available for retail consumption. I have seen one or two sites in China that have offered the OEM card at very high prices and w/o any sort of warranty since it is OEM. Additionally, even if the card is SATA-III capable, the W520/W530 is not capable of running at that interface speed in the in PCI-e slot.
