Will you ever need one at home? Never. Is it more than most businesses will ever need? Probably. Is there an existing customer base out there for the product? Definately]]>Apr 22nd 2009 11:10AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/
The system I work on has a database that largely (not actually, but the important bits) fits in 64GB RAM, so we probably wouldn't benefit significantly from faster disk. But if the database weren't in RAM... I know caching is great, but it only takes you so far.]]>Apr 22nd 2009 1:15PMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/Apr 22nd 2009 9:28AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/Apr 22nd 2009 9:50AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/Apr 22nd 2009 9:57AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/Apr 22nd 2009 9:37AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/
What happens to my data when a tornado knocks out power for 3 days? Can I recover critical data in the case of flooding?

I don't understand why we aren't just using hundreds of 32GB CF (the fast kind you use in a cannon DLSR) in RAID 5 with a couple GB of RAM like this set up as a battery operated write back cache in case of power outage.

But we run full 2K uncompressed files on our Stone system on much cheaper HDD raids without problems, so, to us, this doesn't make much sense.]]>Apr 22nd 2009 2:29PMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/Apr 22nd 2009 10:04AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/cob·ble: To put together clumsily (ex: cobbled a plan together at the last minute)

Also someone said that on a Raid0 SATA rig your throughput is higher then the 3Gb/s cap by the bus; doesn't make sense to me, but is that true? ]]>Apr 22nd 2009 11:37AMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/
The 3Gb/s limit on SATAII is per lane (e.g. mini-SAS cable has 4 lanes).]]>Apr 22nd 2009 12:02PMhttp://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/http://www.engadget.com/2009/04/22/texas-memory-systems-goes-texas-hobbles-together-ramsan-620-5tb/ * 2 ports standard; up to 8 ports available
