Hi,
After viewing some 900p reviews from internet ,somebody said that
" If you reach TBW limit on the 900P, Intel will forcibly move your drive into read-only mode."
Is it real ?If I reach TBW limit before warranty date ,is the warranty still available or not ?

Hello ZephyrWu,
Thank you for your interest in the Intel® Optane™ SSD 900P Series.
The Terabytes Written (TBW) value, as a measure of endurance, reflects the total amount of data that can be written during the SSD's life span (https://itpeernetwork.intel.com/ssd-endurance-what-does-it-mean-to-you/ https://itpeernetwork.intel.com/ssd-endurance-what-does-it-mean-to-you/). Once the limit is reached, the SSD enters read-only mode.
As per our warranty policies, the warranty period is defined as whichever comes first: the five years from date of purchase (depending on model) or once the SMART attribute E9 reaches the normalized value of 1 (TBW reaches its limit).
For more information regarding our warranty policy, please check the following link
https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/intel-client-ssd-module-warranty.pdf https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/intel-client-ssd-module-warranty.pdf
In case you have any other question don't hesitate to ask.
Regards,
Andres V.

Hi Andres,
Thanks for your kindly reply .May I have Three more questions ?
1.If the drive enters read-only mode ,is it possible to recover writable even if the warranty ends ?
2.Is it possible to request RMA when drive usage closes to TBW limit ?
3."Enters to read-only mode when reaches TBW limit" ,"When TBW reaches limit first the warranty period ends"
Does this 2 policies apply to all Intel SSD models ?Or only 900p and other 3D X-Point products ?
Thanks !

Hello ZephyrWu,
I'll gladly try to answer your questions.
As stated in the warranty policy link attached in the previous post (https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/intel-client-ssd-module-warranty.pdf https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/intel-client-ssd-module-warranty.pdf ):
Which basically explains that you cannot request an RMA for an Intel SSD which have reached its TBW limit.
You can request a RMA for an Intel SSD that is close to reaching its TBW limit if we conclude that the device presents and abnormal wear-out that may be due to a manufacturing flaw. Also, it will not undergo a RMA if the SSD is used in an environment which it was not designed for, an example would be to use a consumer SSD (designed for personal use) in a server environment (designed for heavy workload).
Additionally, could you please rephrase your first question, since I'm not following you: If the drive enters read-only mode ,is it possible to recover writable even if the warranty ends ?
Perhaps you want to know if it is possible to go back to a writable state. If this is the case, then no, you cannot go back from a read-only mode. This has to do with the fact that reaching the TBW limit implies a physical wear of the available memory blocks. It is not a software-driven decision, it's a result the normal (and expected) physical wear-out that cells (in any SSD) go through during a writing process.
Please let me know if this answer your questions.
Regards,
Andres V.

Hi Andres,
About first question ,I think you are totally knew what I mean and answer me already .
I have fully understand the first two questions ,how about the third question ?
According to the current warranty policy you provide ,I didn't find any article about TBW limitation .
I have several Intel SSD including SATA and PCI-e ,it sounds not good if TBW limitation policy is applied to them all .
For example ,my P3600 1.6TB PCI-e drive has been written about 900TB data and the SMART attribute 05(percentage used) is only 4 .
Will this drive also enter read-only mode when TBW reaches 8.76PB ?
Thanks .
Zephyr

Hello Zephyr,
The warranty policy statement and the TBW value are related through the endurance limit concept. Since the Terabytes Written (TBW) value is a measure of endurance, one can rewrite what is present in the warranty link provided as: "… the usage of which has reached its TBW limit…"
Regarding your question about the Intel® SSD DC P3600 Series, you are correct, once this SSD reaches the 8.76 Petabytes Written (PBW) it will enter read-only mode. Please keep in mind that the NAND flash wear-out is an expected behavior in all SSDs, and most manufacturers use the cumulative writes value to reflect its endurance limit. Our SSDs will enter read-only mode so you can access your information even when the endurance level limit is reached.
Perhaps you would like to check this link for more information on SSD endurance: https://blogs.technet.microsoft.com/filecab/2017/08/11/understanding-dwpd-tbw/ https://blogs.technet.microsoft.com/filecab/2017/08/11/understanding-dwpd-tbw/
