Hmm... process:
0) I want a NAS
1) I want 4x4TB drives, I'd like to spend around $600 for NAS alone
2) best one I can afford: DS420+, I spend 10 minutes reading reviews and it's OK =>
NAS choosing done
3) I look at the compatibility list:
Synology strives to improve product compatibility. Check out our compatibility list before purchasing the peripherals you need.
www.synology.com
it gives me 3-4 potential candidates (consumer NAS drives)
4) I spend 20 minutes reading comments and reviews
5) I choose ST4000VN008 =>
drive choosing done
That's probably 40 minutes total. Now I can spend some more quality time thinking where to get that $1100 total.
I pay, admittedly, a hefty sum for Synology's time spent designing and testing, but the product is really good and ticks most of my needs (it works, it's fast, it has good features, it looks OK, it's silent and it has a very nice warranty and service).
Is it the best server I could have for that money? No. So what?
Going DIY for comparison:
0) I want a DIY server
1) I need a small mITX case that can fit somewhere in my flat and doesn't look hideous
... and it's September already.
Also, you may be one of those people who do quick buying decisions. If yes, I absolutely envy you.
I'm not one of them. It takes me a lot of time to choose stuff. It's a personal flaw, but one's existence is built around personal flaws.
Economy even has a name for this: transaction cost.
The good side of this is that by the time I'll choose all the parts, read all the reviews (including the
absolutely crucial matter of fan pitch), I'll probably save enough money to buy it instantly.
