Seagate Hybrid drive, or full SSD, in a Lenovo IdeaPad Z570?

I'm wondering about the utility of upgrading the stock HDD in my Lenovo IdeaPad laptop (Z570 1024AYU) to one of the Seagate SSHD "hybrid" drives. I bought the machine from Costco in early 2012 so it doesn't exactly match any of Lenovo's stock models at the time. Specs are very hard to find online and when I do find a spec list it never specifies what version SATA it has, but I'm assuming it's just "SATA", not SATA II or SATA III.

So if it is just plain SATA, would it even take advantage of the extra speed of today's SSHD hybrid drives or an SSD drives?

Your laptop uses SATA III. You won't get much improvement from an SSHD because the SSD cache is so small. For best performance you'll want an SSD. I like the Samsung 850 EVO as they have the best combination of storage space/price/warranty. The 850 EVO 250GB costs about $115 and comes with a 5-year warranty.

Thanks for the info "LordConrad".

Funny you mention that Samsung SSD - I actually have a 850 EVO 500GB SSD - new, in-box and untouched - sitting around waiting for a desktop/gaming build! (Got it on sale at Newegg for $204 a few weeks ago.) I guess I just didn't want to bust it out and try to install it in a machine that I didn't know was compatible.

BTW, if I may ask, how do you KNOW that my laptop supports SATAIII? I ask because I found so many contradictory articles / forum posts / spec sheet reports that I was unable to find a consensus opinion on the matter. The best I could gather was that the HM65 chipset does support SATAIII, but some individual mainboards do not. Even on the Lenovo forums there is disagreement on Z570 support for SATAIII.

Anyway, thanks again. Any further info is appreciated.

As you mentioned, I went by chipset support. Also, it would not save OEMS any money to downgrade a motherboard to only support SATA I or II, since SATA III support is built into the chipset. Even if the motherboard only supports SATA II, which I doubt, an SSD will still perform much faster than an SSHD.
