Re: Cloudspeed Gen. II SSD firmware update?

As a side note, the Micron 5100 series drives work perfectly without causing Dell faults in my tests so hopefully this will light a fire under someone’s butt in the Cloudspeed firmware engineering dept. They are a better performing product in my tests as well, despite being eTLC based (Cloudspeed Eco/Ultra are MLC/eMLC) so Sandisk needs to fix this for a “server class” line to remain competitive and effectively usable in our usage cases.

Re: Cloudspeed Gen. II SSD firmware update?

Sorry I missed your last message. So they are faulty for you, yuck. I put some in a r620 that has a PERC H710P. They are reading without a fault in this model, however the write speeds are horrendus. On a vmware server, in a brand new VM, I am getting 50-60 mpbs write speeds, while my reads are at about 800 mbps. How are your read speeds, what program is running on top of these for you?

Sorry, how are your *write* speeds.

Its write speeds are normal but I can't really live with the false status flagging issues.  Re: your performance issues, maybe you should check out this bug fix for VMware when using SATA vs SAS disks:

The link says it only happens with cheap spinning disks, not ssds.

Re: Cloudspeed Gen. II SSD firmware update?

The user comment at the end of the article noted that it affected SATA SSDs as well, since this is a SATA device issue (vs SAS).
