Hi, please i would like to know if there is any speed decrease or problems if i use this hard drive cable A1278 model 821-1226-A instead of 821-0814-A.
Macbook pro mid 2012 can use an old hdd cable , but i would like a confirmation that all will be good and there is no impact on performances,read/write datas speed etc...
Esta é uma boa pergunta?

Before doing this highly dubious switch, you might want to read over this question: Using new hard drive cable in older machines 821-1480-A

We have test them and have no notice in decrease performance or issues running that cable as we have had a lot of troubles with the new cables failing a lot

Who is "we"?
They are different lengths, although some places will sell you the same cable for these two different part numbers. 821-0814-A is longer than 821-1226-A. I advise using the correct cable as extra stress on the cable will most likely mean it doesn't last as long as the correct one.
