Solved! hello everyone , i have an Acer Aspire 3 with i3, 4 GB RAM. i want to know if my laptop supporting SSD ?

Solution
Which laptop model, specifically? AFAIK the Aspire3 first came out with Skylake (i3-6xxx), so would be a very good candidate for an SSD.

Realistically, any laptop with a SATA port can "support" an SSD - just a matter of speeds available.
Even an older laptop with SATAII will feel substantially faster with a budget SSD installed.
