any recommendation for good 1TB ext hdd ? gonna use it with my MBP
Seagate 1TB Expansion, cheap and well, it's up to your luck.
My company uses it for daily backup purpose, about 2~3 times a week plugged overnight (they have others as incremental backup).
So far the usage is being moderate I must say, no issue so far.
If you're using for critical data, buy 2 copy or maybe 3 as you can afford to make several copies for mirror backup, in case 1 down, you have another copy.
Most importantly is when you do operation (read or write) on the hard disk, make sure it has as least shock or vibration as possible to prevent physical bad sectors, this will permanently destroy any data, hard disk can be laid on any surface as long as it's stable along the operations.
If you're going to use it in rugged environment, best is to save up for external SSD, or couples of USB3 flash drive (big in size?) but due to wear and tear, flash drive chips will wear out in 2~3 years if you use it daily. I believe SSD will have much better durability in this case.
