According to this Samsung link, 250GB drives are good for 150 TB Written. My total TB written so far: 0.32 TB. There is no way I would go over the 150 TBW. That is a non issue. Unless storage space is a concern, SSD is the only way to go, and has been that way for a while. Raw data for my SSD is as follows:
In a later test with 240-256GB drives, the first to fail was the Samsung 840 Evo... as expected, as the only one with TLC NAND. Even so, it made it to 600TB written (2400 write cycles), while all others exceeded "1PB in writes".
I have not had any problems with Toshiba last four years. I carry with me plastic tubs and place laptops on two edges of tubs so it has 360 degrees of air and they kept cool.
Well, you clearly don't write much data on it, that's only 320 GB. When you program and handle lots of data that's written onto the disk the numbers balloon fast, add to that things like torrenting you might want to do and...
Check what drives stats are soon, with unraring looking at 15gb per day. £80 drive why worry to much.

Can't see much data sadly, Power on 577 Days. 100% lifetime left, Condition Good. 145,013,378 Blocks Read, about all I can see of interest sadly!
Assembling, Building them would involve making your own chips and wire and hard drives, your just connecting pre built things, therefore assembling.
