January 23, 201115 yr I'm using a 1tb eads Drive as my cache now and I'm having transfer speed issues from my other machines in the network. I'm on 1 Gb network and just seems slow to transfer files to cache drive at 10 MB a sec that Mega Bytes not bits. Wondering if that EADS drive is the issue
January 23, 201115 yr Your disk may be slow depending on if it needs to be jumpered and what version of unraid and hardware you are running so a bit more info please. See: http://lime-technology.com/forum/index.php?topic=8780.0 As for cache drives, I don't use one. I get around 30mb/s writes to the array, with a hdd cache i was getting it up around 50-60. The only problem with ssd's are the size. Unless you want to copy one blu-ray rip to use straight I found I probably saved maybe 10 mins for a hdd cache, ripping the blu-ray to iso still took up to an 30-60 min so I found cache's not that much use.

Josh I have jumpered all the EARS drives (Right out of the packaging) I'm starting to think it maybe just an issue with moving files from one hard drive to another. I don't really know. As I write this it is moving files to the unraid box at around 22 MB/s
January 24, 201115 yr i have an old samsung 500 GB as cache drive can write to it at +70mb/s from my gig network if you have another drive laying around i would try to see if that goes better... is the cache drive on a port on the mobo ? or is it on a pci bus ?
January 24, 201115 yr then i asume it will be the disk giving you problems... I have seen other people on the forums who achieve 65+ speeds to the cache drive so i am not the only one try to exchange your cache drive for another one and see if it get better... you are sure you enabled the cache drive for all your usershares ? otherwise you would be writing to your array directly and still then 10mb/s would be slow ... i write between 30 and 40mb's straight to my array ...
January 25, 201115 yr Author Yup cache drive is enabled on all the shares at this point. I ordered a 120 GB Corsair SSD today. I hope it makes a big difference One question about the SSD. what should I set the Min. free space: to in the cache area of unraid? the ssd drive again is 120 gb
