What's the best SSD to use?

[Rickinfl]

I have tried 2 brand new Sandisk 240 gig SSD drives and both after a day or two FreeNAS says my boot pool has unrecoverable errors.

So what brand works because Sandisk seems not to be.


Thanks,
Rick

Hardware specs? You're the first I've seen to have issues with Sandisk SSD's as a boot device.

More information on your setup would be helpful.

Running Tyan S7012 Motherboard 2 - 6 core X5650 Xeon. 24 Gig of Ram. 8 - 3 TB drives.

I have 2 of these setups both get SSD errors. Other server is same motherboard, but 2 - 4 core X5620 Xeon.

cksum are usually cable issue - change cable and try a different sata connector

 

[Rickinfl]

I've tried many cables. I'm trying a 1tb Hard drive right now to see if it's an issue with SSD

 

[Rickinfl]

Here is what's strange and makes me think it's not the SSD. Same system hardware I loaded pfSense on that SSD and it runs fine no errors. I'm thinking FreeNAS doesn't like that SSD for some reason.

 

[Jailer]

I'd run memtest on your server to rule that out.

Also what are you running for a power supply?

 

[wblock]

Same system hardware I loaded pfSense on that SSD and it runs fine no errors. I'm thinking FreeNAS doesn't like that SSD for some reason.

Or it could be that pfSense does not use ZFS and so just does not detect problems with data errors on the SSD.

This could be due to a semi-working SATA controller on the motherboard, one that is not well supported by FreeBSD.

Or it could be that pfSense does not use ZFS

The latest release supports ZFS if the user specifies it during installation.
