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 ?
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
In case you have any other question don't hesitate to ask.
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 ?
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... https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/intel-client-ssd-module... ):
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.
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 ?
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.
