Hey all,
As many others have been doing, I have been buying certain SSDs that included powerloss protection (via capacitors, etc) because data security and integrity is paramount.
Crucial SSDs post-M4 (such as the M500, MX100, etc) have listed and advertised this as a built-in feature.
Apparently, there is a big disconnect between what it does do and how it actually operates; generally, not what everyone thinks.
The (AnandTech) article explaining it all was released about 4 days ago and I was completely surprised by the news and all the details.
I have not seen the information propagate over to the forums here. Having seen a post by a fellow forum poster, from a couple days ago, about the protection being included with the links to the Crucial pages listing the feature, I thought it would be a good PSA. This is to bring attention to anyone not yet aware of this. Credits to Patrick, as he seems to have hinted about this in the same thread that prompted the Crucial site links.
Going forward, if this is a requirement, it is key to know how the 'powerloss protection' is implemented by a manufacturer in a particular SSD model.
Powerloss can mean a number of things in the event of a power disruption (loss, fluctuation, etc) and this may include: keeping the data already on the disk intact - not get corrupted; keeping enough power to commit any data in transit/in cache or RAM/etc (still volatile) to the disk; etc.
Hope this helps
