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 <https://quotewizard.com/> [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 > > > >
