545s non-enhanced power loss protection

Hi

As stated in the Intel SSD 545s Series specification, this drive does not have Enhanced Power Loss Data Protection. In my understanding, if there is no enhaced protection in the 545s drive, then probably there is a standard (non-enhanced) protection against power loss. Could you explain what type of protection against power loss is used in 545s and what are the differences from the enhanced level of protection in the context of protecting user data.

 

Also, since I am in the process of choosing an SSD for purchase, it is important for me to know if the 545s has the data protection technology described in the document by the link: https://www.micron.com/~/media/documents/products/white-paper/ssd_power_loss_protection_white_paper_... on page 3 under the heading "Countermeasures in

Client Computing ". If not, does this technology provide more reliable data protection in drives with this technology in comparison with 545s?

Hello Rrust,

Thank you for contacting Intel® Memory & Storage Support.

As we understand, you need assistance with your Intel® SSD 545s Series. If we infer correctly, please, review the information below:

• As stated on

https://ark.intel.com/content/www/us/en/ark/products/125027/intel-ssd-545s-series-128gb-m-2-80mm-sat... and as you mentioned your drive does not have the “Enhanced Power Loss Data Protection” feature since this is a consumer SSD and this kind of features are available on SSDs designed to be used in a server/data center environment(https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=35125&0_EPLDP=True

), in the other hand this SSD has the “End-to-End Data Protection” feature that ensures integrity of stored data from the computer to the SSD and back.

• The Enhanced Power Loss Data Protection prepares the SSD for unexpected system power loss by minimizing data in transition in temporary buffers and uses onboard power-loss protection capacitance to provide enough energy for the SSD firmware to move data from the transfer buffer and other temporary buffers to the NAND, thus protecting the system and user data.

• The feature that you mentioned seems to be similar to The Enhanced Power Loss Data Protection feature that comes included on some of the data center SSDs (

https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=35125&0_EPLDP=True

).

We hope you find this information helpful. If you have future questions, please don’t hesitate to contact us. We will be more than happy to help you in any way we can.

Have a nice day.

Best regards,

I do not have 660p. I am thinking of buying 545s or another. And it is important for me to know is the 545s has the data protection technology described in the document from my first post.

For more clarity, I ask a few questions about Intel SSD 545s Series SATA 3, 512GB:

  1. What technologies of protection against unexpected loss of power are present in this model? Preferably with reference to the documentation or description.
  2. Is the data recorded in NAND or "data at rest" protected in this model If the drive loses power while writing a second pass of more data to the same cells?
  3. Does the "end-to-end data protection" technology help save data in case of a unexpected loss of power?

Hello Rrust, Thank you for your reply, To answer your questions. 1. This SSD does not include power loss data protection features on this consumer SSD as stated on https://ark.intel.com/content/www/us/en/ark/products/125027/intel-ssd-545s-series-128gb-m-2-80mm-sat... this kind of features are available on SSDs designed to be used in a server/data center environment (https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=35125&0_EPLDP=True) 2. No, the data loss protection is not included on this consumer SSD. 3. No, The "End-to-End Data Protection” ensures the integrity of stored data from the computer to the SSD and back but it does not protect data in case of power loss. If you are interested in having a power loss protections feature we advise you contact your motherboard/controller OEM (original equipment manufacturer) to check for options like a BBU (battery backups units) or a similar solution compatible with your PC that may help you in case of an unexpected power loss. Thank you for your patience and understanding. Best regards, Josh B. Intel® Customer Support Technician Under Contract to Intel Corporation
