Hi, I am thinking to upgrade the hard disk of my Satellite P750-02Q, but I don't know what SATA type it is (SATA I or SATA II or SATA III), and how many disk can it support? I am thinking to slot in a SSD disk in there, but if it can support 2 SATA disks, I can use the existing 750GB 5400rpm drive as the second storage.
Remove HDD cover and built-in HDD. On the HDD label you can find all these info. Buy the same HDD but with more capacity.
I have older P500 and cannot say for sure if your P750 can be upgraded with second HDD. If yes there must be HDD cover for second HDD. Remove it and check if the HDD connector is available.
Assuming you have two drive bays then you will have to locate (or make) a caddy and securing screws. The P500 2nd drive bay is deeper (takes 1Tb drives) than the one populated by Toshiba and requires a dedicated caddy. I would guess your drive will be SATA 2 (AKA SATA 300). It will be a toshiba drive so get the model number from Device Manager and search here http://storage.toshiba.eu/cms/en/ (there are several Toshiba storage sites so google if you can't find it there. I don't know how to establish the laptops maximum SATA speed and I would buy any make of SATA 2 drive balancing capacity against cost. I'm currently running 750Gb Samsung and 500Gb Toshiba. The Samsung replaced the orignal Toshiba 500Gb boot disc that at 20 months turned into a brick that at best was recognised as a storage device of an unknown type/capacity
Generally speaking it makes no difference if you buy SATA I, SATA II or SATA III. The physical interface is always the same, only the transfer speed is different (SATA III is best one) but that’s not important for normal HDDs because they are too slow. Only SSD drives can use the fast SATA III interface but they also run on SATA II or I interface.
So don’t worry. Just make sure it’s 2.5” drive with SATA interface.
Thanks everyone or your reply, all very helpful. Just for everyone's benefit, the HDD model number is MK7575GSX. Didn't really find it on that Toshiba storage site and haven't really done further research, but I'm just going to get the SATA II SSD anyway cause they are backward compatible as PinkPhanter said
Oh and the P750 only supports 1 HDD My older A300 supports 2, chose the wrong notebook, oh well, at least this is now much faster hehehe
