We have a client that wants to upgrade SSD hard drive on a 13" MacBook Air. They have 128GB and we want to go to 256GB or even 512GB (or amounts close to these numbers). We know it's possible, but some questions
1) What is a good SSD drive to buy from a Mac Air? I can google and find many, but good to have an idea of what is a trusted recommended model. (note we are in UK so UK suppliers are a bonus)
2) I assume Apple don't directly sell these?
3) Could we do this in-house, or should we just pay another company to do the actual hard drive swap. We've fixed many Windows laptops before. We've been quoted £50 +VAT for this somewhere else (but we have to get it to them and back).
