Just as the title states I'm wondering if its possible for the government to recover data from a encrypted ssd that was wiped? Thanks in advance!
I would clearly say yes. To explain this let's take a look at the differences between HDDs and SSDs. On HDDs data is always written on free space in one order. So you definitely know when you have overwritten one block often enought the data is gone. (also depends on the HDD. On some there are spare parts to recover the data)
At SSDs is a big difference. To comply with wear levelling, the SSD must constantly move data around the drive to ensure all blocks are worn at an equal rate. So if one data block is more worn out than an other, you overwrite just that "good" block multiple times, but the data is still in the "bad" sector (your encrypted data). As you can see it won't work with normal eraser which just overwrite the space.
If you want to secure erase your data on a SSD you need to take a look at ATA Secure Erase. At this procedure the command instructs the drive to flush all stored electrons, forcing the drive to “forget” all stored data. But this is not the only way to delete it. On some drives you can delete the encryption key which is used at the SSD. It dependes on your SSD. Look at your manufacturer to get better information about it.
To answer you question more specific: If you use normal erasers it is possible that there are some datablocks left behind. But these blocks are encrypted anyway. Normally it should not be possible to decrypt them (only if you set the encryption correct up). Anyway, if you want to delete the whole data look at your manufacturer to get to know how to delete it safe.
