Interesting.  I wonder why not.  The flash is (should be) stable and the logic to flush the remapping data to flash when it notices that power has gone critical should be straight forward and bomb proof.


<SL> Without Power Loss Protection, the flash would not "notice" anything – it would be dead/no power.


<SL> Only SSDs with capacitors (or some other external power source/battery) which would provide a couple of seconds of juice, would be able to flush their cache.


<SL> That is the difference between Data Center type SSD devices and Consumer / Professional devices.  The Intel 900P series are _professional_ devices.

Marius et al,


Be aware and the Intel 900P series SSDs do not have power loss protection, so the data could get "scrambled" by power loss or system abend/restart.


Otherwise, they are unbelievable drives!!  (If not a _little_ pricey – 150% premium)





Intel 905P 480GB $600 ($1.25 per GB)

Samsung 970 Pro 512GB $250 ($0.49 per GB)

Samsung 970 Evo 500GB $200 ($0.40 per GB)
