Hello Everyone,

 

I have a question about the Flash memory, our clients currently have 32GB and 64GB built in. As i understand, when the HP write filter is enabled, writes are appended to RAM instead of the Flash memory.

 

My guessing is that this saves a lot of I/O from the Flash memory. Due to reasons we are currently looking into running our 2000+ thin clients without the write filter so we can keep them up to date. In our 24/7 hospital it is not doable to send a new image with the latest Windows updates every couple of months...  Nor is it to deal with the write filter every time to manually append the updates. It is at least two reboots.

 

So without the write filter the built in Flash memory will be used a lot more i would guess as it is not redirected to Ram. Is there any information about the lifespan of the memory/maximum writes? If all these write actions would mean the lifespan of the thin client is severely reduced we have to come up with another plan... It would not be good if after a couple of years the max read/writes on the M.2 disks have been met and we are left with duds.

 

Hope someone has some information about this

old  do not wear well (huge evolution from 32GB days to now) google why,

ok 2: (one is vastly better eeprom cells ) and two: vastly smarter wear leveling,  now. 

 

upgrade them is always best if not wanting lots failing at once,  upgrades must be part of any plan ? NO?

what else would you need to know on flash memory?  google evolution...

NO warranty answers by me.

I found some information here just now: http://h10032.www1.hp.com/ctg/Manual/c04533143

So i have to figure out what type of memory is inside our T640's

 

"ask your M.2 card maker this",

We buy a complete thin client, not a separate M.2 card. I would assume HP uses standard drives within their models.

All the technical information i can find about the memory inside thin clients says: eMMC Memory.

As it is not expensive memory i am going to assume it is MLC.

 

I would think that this means bad news when not running the write filter. But the documentation also says this.

Meaning that our 64GB thin clients should be fine according to HP.

 

hmmmmm
