I ran some benchmarks and 4K read speed really takes a hit with FDE: 2xWestern Digital blue label RAID 0 : 0,65Mb/s (for refrence) Crucial M4 without FDE : 19

I ran some benchmarks and 4K read speed really takes a hit with FDE:
2xWestern Digital blue label RAID 0 : 0,65Mb/s (for refrence)
Crucial M4 without FDE : 19,07 Mb/s
Crucial M4 with FDE : 5,59 Mb/s
however the benchmark shows that a SSD is still substantially faster than a classical RAID 0 array
- mike-cardwell 15y agoNot enough information to verify the usefulness of your benchmark. Were the volumes/partitions aligned? What technology/cipher/keysize did you use for the FDE? Does your CPU have the AES-NI instructions? Does the encryption tech that you're using take advantage of those instructions? FDE on any type of media causes no slow down if the CPU can encrypt/decrypt at least as fast as the disk can transfer data. It's not correct to say that FDE always causes slow downs.
