SSHD Preformance with ZFS

[Johii]

I want to build a NAS from my old motherboard and some new disks.

I want to put 4-6 seagate 2,5" 1tb hybrid drives in it. But i'm unsure how ZFS will work with with that. Would it be better to not use hybrid drives and have 1-2 SSD disks and 4-5 normal disks?

The system is gona be a dualcore E8400, 8GB RAM, max 6 x SATA300.

Any advice / experience on the subject would be appreciated.

Hybrid drives will likely provide no benefit for ZFS and file servers. SSDs will be pointless because you need MUCH more RAM before you start thinking about ZILs and L2ARCs(and even then, only for certain types of workloads).

Forget about the exotic things, miss FreeNAS only wants one kind of man: RAM!
You'll see a performance increase when adding RAM. SSDs are almost never good for home environments.

I've given my new system some thought, its going to be: 6 TB, 1 TB of which is going to be for VM's, 2 x 8 GB ECC RAM, 4 dimms, 1x PCIe 2.1 x8 for future expansion to 10GBase-T. And minimum of 4 sata3/6Gbit/s connectors. Again for future upgrades when 1TB SSD hit less than 1 dkk pr. 1 GB. Dual Intel gigabit ethernet, preferably low power cpu and 2'5" disks.

backup will be done at remote location. This is going to be for a home data and test environment and is hopefully going to give me some experience running NAS/SAN environment and is not for important business things. I curretly have my data on 2 different storage solutions which are to slow and to small.

I plan on running ZFS in RAIDZ1 with X amounts of disks depending on what's cheapest and or most convenient.

What kind of performance should I expect from a system like this?

Any feedback would be appreciated.

And thanks cyberjock for already teaching me a million things without purchasing a single disk.

I'd use SSHDs for install drives.. Probably netbooks etc where you will see some performance boost..

Although you say its for home data/test environment, if you have been listening to cyberjock, add another drive and go RAIDZ2
