Thats true, though recently on Newegg there have been some sales on the ex900 and ex920 bringing it to $70. Those have gone back to $80 but I'm trying to find something on sale now.I think it's going to be either 250gb NVMe or 500gb SATA in M.2 for under $80. NVMe SSD's are still quite pricey and any good 500gb versions are like $130+.
NVMe.

Would get this, except in HK it is listed at $85, also some potential issues in its endurance, along with being a level below in speed and value compared to the 1 tb version.$69.99
