such passion, do you work for WD?


Long ago when rock was dirt i bought a Drobo nas box it was the only brand to buy back than. I use it every day for home use and it has gone through many drive crashes with success. But I only used 6.5T or 45% of its capacity to date. I use it write once read many times. I dont delete stuff. Not with out trying i have never come close to filling it up. Only a small percentage of home owners could fill 10-20T with content. Home usage is small and an SSD equivalent is possible. A ssd array would allow me not pay for off site backup. About once a year i need to replace a drive or two, this costs money.

A Drobo box is way slow, even for a small office environment. co-workers would thank their IT person if he gave them SSD.

No, I don’t work for WD, but I would call myself a home network enthusiast / hobbyist.

Interestingly I’d never heard of Drobo until you brought it up. Probably not big in Europe.

However your argument is still weak at best. Zero redundancy through SSD’s is not a great way to store data and unless you have it plugged directly into the PCIE bus, you’ll gain zero performance advantage unless you have a 10Gbps LAN, but seeing as you think 20TB in SSD’s is a drop in the ocean, I’m sure you have this little and so much more, so who am I to comment?

The limitation in most home storage boxes is the hardware processor. The vintage Drobo box i have is very slow but it has worked as expected, rebuilt through many hard drive failures.

A proper better setup would be to have something front end storage directly accessed by the network and a JBOD storage in back. Every day say 3am the network server would transfer front end changes to the Bunch OF Drives backup box. That is if you want to keep your backup in house.

its like comparing apples vs oranges but SSD storage is totally reliable than the spinning rust like you dad did.

is raid5 functional for a write once read many SSD situation?
Netflix is gaining popularity, how much home storage is necessary?


love you more...

i have 5 samsung 960, 1 for crappy windows and 4 in raid0 for mac os hitting over 10,000 mbps in reading and over 5,000 mbps in writing speed, i would not use old drives for data storage in raid 1 or any other raid mode, i have two 2 tb hard drives and what i do is copy the same data to both drives individually, i also have bluray burners so i burned the data i know i'm going to keep for sure, that way i have another extra backup just in case and for the record bluray media can hold up to 50 gigs of data on a dual layer disc, so is not like i'm going to have 25 dvd around the house just to backup 100 gigs of data, that only takes 2 bluray discs, even the 128 mb cache hard drives are still way too slow, when you compared them to sata ssd so just imagined the difference between an old mechanical hard drive and a samsung 960 nvme m.2 drive, i really hate putting data in and taking data out of any mechanical drive, i can copy paste over 100 gigs from my 4 samsung 960 raid0 in less than a minute, that same task will take 10 to 20 minutes in a mechanical drive. i really don't have time for that. i like things fast , i always keep the data that i used the most in my raid0 so i don't have to plug my usb 3.0 dock station to take data out from the old mechanical drives, if i need something is already there, which makes things faster
[doublepost=1503774028][/doublepost]the cheap way to stored data is with mechanical drives but that will impact performance, read and write, but if don't mind waiting then an old mechanical hard drive might just work for you, ssd's are faster but they cost more, it really depends on the person budget and point of view, me personally i rather pay more just to have better speed, another point is that not only old mechanical drives are cheaper but they offer higher storage capacity than ssd's but then again the speed issue, any drive has the chance of failure but i think old mechanical drives has more chance of failing than ssd's drives not only that but mechanical hard drive suffer from bad blocks, clicking noise, overheating etc, no thanks i'll pass, last but not least, if you connect the drives directly to the motherboard be ready to have 20,000 sata cables and power cables in your pc in order for you to connect those drives, once again no, i have 4 pci-e m.2 card with no ugly cables, right now waiting on a new 16x m.2 carrier card. if you want those old drives just for data storage simply get an enclosure or a dock station and turn on the drives when you are going to use them then after that turn them off, there is no point of having those drives up and running if you are not going to use them.
