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:

Re: Cloudspeed Gen. II SSD firmware update?

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).

Since it seems that noone has ever answered this question here or in the Enterprise forums, the half baked Sandisk Guard Tool utility doesn't work with its default firmware update settings under Windows.

 

The method to get it to process without errors is to use the non-default firmware update mode (second option in the list I think) which allows you to specify the offset / block size.  Via trial and error with common block sizes, I found that a block size of 256 was accepted and updated my Ultra Gen II drive from ZR07 to ZR08.

 

Even with the latest update on my drive, performance is still very marginal on consumer-type controller platforms (Intel SATA3 in AHCI mode during my tests) and light-load / QD1 performance is conspicuously low.  This leads to very bad scores on consumer-type benchmarks such as PCMark tests, so I wouldn't recommend people snap these up to use for non-server environments.  Their firmware is likely specifically optimized around LSI-based hardware RAID controllers vs consumer controllers, so I wouldn't expect improvement this far into the firmware's development either.

 

There seem to be plenty of bricked versions of these drives floating around eBay with customized non-generic firmware, so updated firmware appears to be crucial for long term reliability--and that generally isn't possible if the drive is not a generic one that can be updated with this unfriendly / DIY-class-support enterprise utility.


ve used SanDisk guard tools for windows. I have tried on Pike 2108 and adaptec 8405 but its not possible to find the disk when its in raid. I have tried with USB 3 sata hdd dock and usb 2.0 sata hdd dock. i have tried to use it on sata controllers on many different pc'c and server's, but its not possible to update. It says updated but its still the old firmware, if i use it on sata controllers it say:

Updating failed
