PM893 3.84 TB really has come down in price at Amazon as apparently have some other Samsung drives. In late March of 2021, I paid $430.66 for 3.84 TB EVO 860. My drive data recently became corrupted, most probably due to an electrical outage and subsequent surge event. I was able to reload my music from a backup, but harbored concerns if the drive life itself could have been compromised. I ordered a 3.84 TB PM893 at the end of of November for $348. It is now shown for $198 by a different seller. However, the reviews on this seller are not good for last 12 months and the other seller for new (one I had used with my order and with good reviews) is significantly higher--higher than I paid a month ago from them. I personally have reservations on whether the significantly lower priced seller is correctly representing/listing this sale.
Regarding sound quality of the PM893 vs the EVO860, I cannot truly give a reliable opinion at this time. I have kept the EVO 860 loaded with music as another backup. My system sounds quite good currently. Certainly, I could shut down and disconnect power off my Antipodes K50 to swap drives again as some form of test, but there would be some time delays in doing so and starting up with new drive. There are also views that shutting down the unit completely with power disconnect like this would require up to several days for the unit to stabilize again for ideal sound, defeating, in my opinion, an accurate sound quality comparison. As noted, I am pleased with my system sound quality with the PM893 installed.
