Question 1

4,800 Total Bytes Written (TBW) ?

Accepted Answer

I believe the person asking the question is confusing TeraBytes Written with Total Bytes Written. 4,800 TBW is exactly the number specified by Samsung for TeraBytes Written. I think, therefore, that the answer from ServerPartDeals is the one which applies. I will cut-and-paste Samsung's comments about TBW for this drive.

Thomas W.'s comment about Total Bytes Written (as shown in Samsung Magician) is correct, but I think that the TeraBytes Written is what was asked for here.

"...up to 10.7x higher TBW* than the previous 850 PRO. The latest V-NAND technology gives you industry-leading endurance backed by a 5-year or up to 4,800 TBW limited warranty.
*Terabyte Written"

Question 2

I want to upgrade my 2012 MacBook Pro's Hard drive to 4TB.  Is 4TB too big for my laptop?  I currently have a 1TB hard drive and it is almost full.  I use my laptop for mobile DJ work, photography, video editing and personal use. I greatly appreciate all helpful answers.

Accepted Answer

4TB is a lot of data, but if your 1TB is nearly full, you need to ask yourself what's filling it. Videos take up a LOT of space, for example. How much of that is backed up?

You also need to figure out how hot a 4TB drive may get. One manufacturer of which I am aware offered a 3TB HDD in a device, but later reduced it to 1TB, people say, for heat reasons. Look into that before committing to 4TB. (Do NOT trust me on heat issues; I'm just relaying what I've heard, not what I know.)
