The problem is constant I/O. Of course you can write 200GB per day for 10 years with those. Probably. But note the details: 200GB per day means *once* per day. Plug it in, write 200GB on it, then remove it again.
In your setup, there's constant I/O. That means there's probably an order of magnitude more data transfered than 200GB per day. Just make sure you take backups regularly
No i got you, i mean 200 gb is essitally them saying 20 writes a day over the same stuff for 10 years. Thats why my ramdrive is no on the raid, but on one 8 gb. And i am not worried if it does die this is just an experament to get me back into linux.
. With raid 0 make sure there all the same size
4. If you can use multiple host USB controllors, most cap out around 50 MB/s but can go up to 60. (i have 6, 2 on the mainboard, 2 pci cards, 2 pci express cards)
5. if done right your looking at ~$200 for a ~210 MB/S drive with response times as low as 70 Microseconds for 52 GBs.(so a lot of money for little space, but faster than a x3 raptors on raid 0 *which is ~$400).
