Would a laptop have a Sata II & Sata III port?

Thu Aug 09, 2018 1:19 am

Hi,

I have Toshiba Satellite P75-a7200 laptop that has 2 hard drive ports. I have 2 Samsung SSD hard Drives and I'm getting Sata 3 speeds (500+) on the one drive and the 2nd drive I'm getting Sata 2 (250+)speeds.

I just assumed that both would be Sata 3. But I can't find any documentation about the specs on the motherboard.

So I'm just curious would a laptop come 2 different Sata type ports, or is this a Windows 10 setting issue?

If it's a Windows 10 issues what should I do.

Thanks!!!!

Intel ARK for HM86 chipset shows 4x SATA 6Gbps ports and 2x SATA 3Gbps ports, so alas, what you're seeing doesn't surprise me too much.

Ok I kinda understand. But if it can support 4 x SataIII Why would the 2nd drive port be Sata II?

Thanks for the great info!

In the world of laptops, cutting unnecessary corners is the norm. Don't expect logical design choices. They'll do anything to save (literally) a penny.

Most laptops with optical drives run them on a SATA2 port, so it's not farfetched to expect the same for your secondary hard drive bay. If you had a HDD in that bay, you wouldn't have even noticed.

BTW, is there a dedicated 2nd hard drive bay in this machine (2HDD + Optical), or did you put a hard drive caddy in the optical bay?

Yes I do have 2 hard drive bays. It's kinda crappy running my SSD evo 860 or 850 I get fast speeds off the USB 3.0 cable than the 2nd HD bay which is internal.

I presume you talking about CD/DVD bay as "second HDD bay" since mechanical limitations of optical drives limit your speeds there are no reason for manufacturer to waste monies in providing support for SATA III. On other hand IBM/Lenovo offers as option different firmware to support such speeds for second HDD in RAID configuration only.

Not necessarily - my Thinkpad (a T430) has an mSATA slot as well as a standard 2.5" bay, in addition to the optical drive bay. So in mine, I've got an mSATA SSD, a 500 GB mechanical hard drive, and a DVD drive. The mSATA slot is only SATA-2, but the 2.5" bay is SATA-3.

Well, in my particular situation main HDD (SSD) is SATA III, ultra bay occupied by "regular" HDD with platters (is ATA-300 relaistically speaking, with adapter for SATA connector). and internal slot used for cache drive. which is in your configuration mSATA SSD. Second W530 in fact does have different firmware from the factory to support RAID option and does have much higher transfer rates than the Ultra bay in other W530.
