June 15, 20188 yr Hello Guys, can help someone? My Cache SSD is only writing with 60-67MB/s. I think its an network problem, because if I do a write speed test, the Cache drops only from 445MB/s to 112MB/s by 10GB. Network Fast Mode is on and Jumbo Frames too. Thank you Edit: Its not a network problem, because if i copy something from the cache to my local pc, i have the 117MB/s. thevault-diagnostics-20180615-0606.zip Edited June 16, 20188 yr by BlackHawk3000
June 16, 20188 yr CT480BX2 was crucial BX200 SATA SSD ? Connect in SAS expander. BTW, BX200 is one of worst SSD in the world ( slow in write )
June 16, 20188 yr Community Expert It does look like a network or source PC problem, since first few GBs should be RAM cached and reach line speed.

I hope i get my new Samsung 850 today, so i can try it with a better one. 1 hour ago, johnnie.black said: It does look like a network or source PC problem, since first few GBs should be RAM cached and reach line speed. How can I look where the problem is?

If I send data, directly over the switch, so i get the full 1Gbits. But If I switch to an VLAN over my pfsense, so i get only the half. Update Its an pfSense Firewall problem. Client and unraid in one VLAN, i get the full 110MB/s. Edited June 16, 20188 yr by BlackHawk3000
