Chosen Solution

I’ve tried using a TarDisk to upgrade my storage on my Early 2014 MBA 13" but it froze my computer frequently. So I’m faced with the reality that my best option is to buy a new computer OR attempt to buy an OEM 256gb SSD used. I’ve been browsing ebay and there are just so many variables with different manufacturers and part numbers. For instance; http://www.ebay.com/itm/Apple-OEM-SSD-25… Seems like it’s compatible and would fit, but I just can’t be sure. Is there any way to find out exact SSD model numbers that will fit?

Have you spoken with TarDisk? Something doesn’t sound right here. You might also want to check your system out stem to stern. Is your OS up to date? How much free space do you have on the primary SSD? How much RAM does your system have and lastly when does the system freeze & what are the apps? Fill us in as best as you can the more info the better! If you still want to upgrade your SSD I would recommend going with the OWC product: OWC - MacBook Air 11" & 13" Mid 2013, 2014, and 2015 Buying off of eBay can be a crapshoot ;-{ Unless you really know your stuff you will likely get the wrong part! Many of these folks don’t know what they have so they mark it as being an Apple product and its not. Just looking at a few in your collection I saw four which wouldn’t work in your system. Sadly, paying a bit more you’ll get the right product and get a warranty to boot!
