[QUOTE="NightShade, post: 3344430, member: 29706"] I think the purple's are rated for camera systems. Don't remember what they did but I think they are kinda setup like a shingle system or something like that. But the drives are more purpose built now too. NAS and Enterprise drives don't park the heads unless they are powering down or specifically told to park. Consumer drives park the heads after just a few seconds so in a NAS system they don't last long unless you have constant data writes and reads. The WD green drives were able to have their idle time changed and they worked fine in NAS systems but they made changes on that. Right now my NAS drive have about 35500 hours on them, or just over 4 years solid of power on time. Only had one start to throw some error's and I RMA'd it right afterwards. Replacement has about 19K hours on it. But I have to say I did figure out how to make a consumer drive work in a NAS. I have a script that runs every few seconds once it powers on and basically it does a directory list. It's just enough to force the heads not to park. I just use it as a scratch drive anyway but it has 11K hours on it and still not dead. Most consumer drives put into service on a similar system die within a year. I have heard of people trying to use the purple drives in a NAS system but they never work well. Same goes for the SMR (shingled magnetic recording) drives, they are made to be written to in one big dump and then read from whenever. Basically the data is written in a big long single stripe and the data on a lower tier overwrites part of the upper tier a little bit for anyone wondering. It's kind alike laying the shingles on a roof, going back in later on to replace the shingles near the top or the middle is a pain in the butt so the drives suck for much other thank full backups. I do love my NVME drive though. Had someone over and they started loading up a program, I laughed and said watch this as I was going to load the exact same one on my system. I rebooted my computer and had it loaded before theirs could fully load up. It's like having a sports car and putting it up against a prius that isn't running right. There is just no comparison the speed I get compared to a 5400 rpm laptop drive. I honestly need to replace the boot drives in my server though.
