My initial thought was raid 10 using 4tb (as thats what I use for servers) but I was reading about their SHR and it sounded interesting in that you can use different size drives and not lose any space
The MEDIA data that is stored, is not "active" they do a job, transfer it there, after 6 months it gets erased. but I plan to use the additional storage for doing local server backups as well. (I do back up there servers off-site but its not realistic to pull 3TB over the wire). MY thought was 6 drives in raid10, then use the 2 remainig drives to copy what is deemed critical off the raid10 Date: Tue, 20 Jan 2015 08:44:00 -0800 Subject: Re: [NTSysADM] SHR vs Traditional RAID/RED drives From: [email protected] To: [email protected] The WD NAS drives are only rated for groups of up to 6 and aimed squarely at the consumer market. They're rated for something along the lines of 180TB/year and only an error rate of 1x10^14. The Red Pro drives are slightly better and built for 8-16 bay units backed by a 5 year warranty, have a 7.2K speed and a much better 1x10^15 error rate and warrantied for 550TB/year written, also dropping in capacity to 4TB. If data is critical then move to their WD RE series drives again a 550TB/year rating along with 7.2K spindle and 5 year warranty with an even better 1x10^16 error rate. If you need the density you pay for it in reliability currently, be prepared to keep multiple copies. You mentioned 'terabytes of data' - how hot/cold is it? Also if you're using anything above 1TB drives please don't use RAID5 you'll just be kicking yourself later :( Nathan Shelby Lead Systems Engineer – Quote Wizard [email protected] / 206-753-2626 Malo Periculosam Libertatem Quam Quietum Servitium On Tue, Jan 20, 2015 at 8:00 AM, J- P <[email protected]> wrote: Hi all, I'm looking to drop one of these in at customer site, https://www.synology.com/en-us/products/DS1815+ I'm curious to know if anyone has elected to use their proprietary raid SHR/SHR2, and if so how it stacks up to traditional raid in terms of performance. And on a separate note , has anyone jumped onto the WD RED "NAS" drives yet? I like the idea of 6TB for 270.00, but not crazy about 54k speed or 3 yr warranty http://www.amazon.com/Western-Digital-3-5-inch-IntelliPower-WD60EFRX/dp/B00LO3KR96/ref=pd_bxgy_pc_text_y however , 226.00 for a 4TB 72k with a 5 year warranty does sit a little better http://www.amazon.com/dp/B00LO3KRM8 any feedback is appreciated
