Hello, Reading this forum the last couple of weeks I noticed multiple people having issues with a new iMac with a SSD not made by Samsung and (what I noticed) many users prefer a Samsung SSD. Benchmarks (e.g. this) show that with a Sandisk the write speed is a lot less than with the Samsung SSD. Is this only the case with a 128GB SSD? I'm hoping to be able to purchase an iMac with a 256GB SSD instead of the 1TB HDD at the end of this year (after product refreshment) and since I will be exporting and importing a lot this seems like an unfortunate issue. Thank you.
