will this be okay for ssd as main drive ?

i have a mid 2010 macbook pro that has 320gb hd, would like to replace with 120gb owc ssd drive, since i notice my current hard drive has only 28gb usage, I just need to use this mbp for surfing internet and email, this is it. is this okay with ssd ?

I believe the OWC drives use internals from multiple manufacturers. Therefore you don't know what you're getting and i seem to recall a recent thread where someone had issues with compatibility with one of these drives in an MBP.

compatiability id not s problem

OWC OWCSSDMX6G120 120GB Mercury EXTREME Pro 6G SSD... in stock at OWC

G'day and welcome to the forums.

That 28GB is about standard usage and it appears you are not heavily into music or photography so by all means go ahead and enjoy an OWC SSD. Have used a couple of OWC SSD with no problems whatsoever, but if you want to hear a rant, ask about Kingston and Falcon G.Skill drives.

I'm currently running a 60GB OWC SSD, plus a 500GB HDD. I can fit the system, any applications and my home folder on the 60GB with about 25GB free. But all my media (photo library, music library, and Steam games) all reside on the 500GB HDD.

You shouldn't have any issues with a 120GB SSD, unless you start to get large media libraries.

thanks to all.
now the start, will the used owc i bought with enclosure, how to wipe clean ssd ?

(1) using lion install usb to install osx,
what about existing applications and home folders, how to transfer over to the ssd ?
(2) How to test if the external ssd is working before install as internal drive ? boot using 'option' key ?

Okay pop in the SSD and connect enclosure to computer, connect up your thumb drive, boot and hold down the 'C' button, leave Installer and go to Utilities and choose the SSD and erase, selecting Mac OS Extended (Journalled), into Partition > Options and make sure GUID is selected, back to Installer, and proceed. Existing files etc can be transferred over using Migration Assistant in utilities.

Then power down, reboot holding down Option key and select the SSD.

how good is this ? will this work ?
