Hello, I wanna get a new HDD for storage and I noticed there's WD40EZAX with 256mb cache which has been around for a long time. But there's also WD40EZZX with 128mb cache and I barely find any information about it.
It looks like it's a recent release. It's CMR too and according to the specs on WD website basically the same but lower cache. Does this matter much? It's cheaper (130 vs 150) which with the current prices would be great.
Although I do wonder whether I should go for the WD60EZAX for 180. It's cheapest per TB, gets me some additional storage but the price is just so high :(
