I agree with you 100%
But now we can use cheap discs due to ZFS, ya?
Assuming drives WILL fail, doesn't it make sense to appropriate cost per array instead of cost per drive and then maximize on the inexpensive part of RAID?
I already pay too much for SSD, I cannot justify cost of enterprise drive, what else am I not understanding?
I look forward to your reply
For home use, and a few multi-user environments (like mine) SATA desktop HDD and even PATA HDDs can easily handle the load.
SAS HDDs are more robust however and can handle a much higher load and stress without the likely hood of the drive or the controller failing.
SAS enterprise 15K rpm drives were never intended for home use, that's why a 300GB HDD is over $400, but you get what you pay for. 7200rpm drives are good, but they can't handle the intense load of small or large files simultaneously like 15K rpm drives can.
This is why 7200rpm drives are generally used for SANs and NASs, while 15K rpm drives are used in the servers themselves.
