This is the basic SSD suplied by PC-Engines for the APU1C. It's a very cheap and slow SSD so you should better buy a faster one.

Linear read 170MB/s and linear write 23MB/s are not problematic but random write around 1.5MB/s is bad for IPFire.

Warning: Bad flash

This device has been reported to fail very often and is considered "bad flash".
