HDD Replacement Question

My WD5000AAKS-00TAM0 hard drive decided to give up the ghost a couple of nights ago. Seeing as it needs to be replaced, I am having a tough time deciding which model I should replace it with.

Should I find another HDD with the same build as my old one, or get a new model? (Still a Western Digital)

I’ve had these two in mind: (For a family computer/casual gaming. Keep in mind, some suggestions said as long as the GB storage and RPM matched with the old one, there’s no difference)

Western Digital WD Green WDBAAY5000ENC-NRSN 500GB SATA 3.0Gb/s 3.5" Internal Hard Drive

Western Digital WD Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

Hi go with the blue drive. The green drives are really ment for storage not for a boot drive to run windows on.

I assume an installation disk comes included? Most of the sales I’m seeing just shows the drive itself.

Why a install disk you unplug the old drive plug in the new drive boot to your windows cd and install windows
