Can someone tell me the difference between these 2 SSDs?

Hi

The model numbers are

ZP4000GM30023

and

ZP4000GM3A023

are those the exact same drives? (if so then why different model numbers) or is one model number a different/better version of the other? They both says Firecuda 530 so they should be the same, I just wanna make sure I didnt make a mistake in purchasing. Especially since one is listed as a Preorder which you can purchase while the other is just listed as "Coming soon" and you cant pre order or buy it anywhere.

Sometimes manufacturers change the internal parts or firmware and change the designation. But, sometimes they don't. So, my guess is that they might be identical drives just internally they are different (firmware, controller etc). You could go for some "known" drive like samsung or crucial?
