Latest (2022) WD Gold 2TB WD2005FBYZ-01YCBB3 with firmware RR09 this is newest version at 2TB.

I just did a Christmas gift to my self, due one opportunity at getting unused (open box) HDD, with zero operation hours and active warranty for the next 4 Years.
I did confirmed first product originality at WD website, and then I gave my eBay fight. ;D

Older production was WD2005FBYZ-01YCBB2 with Firmware RR07

---------------------------------------------------------------------------------------------------
The most obvious change is the printing at product label.
Bellow the text WD2005FBYZ there is the text SATA 6Gb/s and next to it a new added text DC HA750

WD website when you check warranty status it report a slightly different description: 01YCBB2 VS 01YCBB3
Older revision = WD2005FBYZ-01YCBB2 RAINIER 7200 128M SATA3 6GB/S 2.0 TB 4HD BLKPT RE S
Newest revision = WD2005FBYZ-01YCBB3 RAINIER 7200 128M SATA3 6GB/S 2.0 TB 4HD RE (RAID EDITION) S

Example of 2016,
much older revision = WD2005FBYZ-01YCBB1 RAINIER 7200 128M SATA3 6GB/S 2.0 TB 4HD GOLD LBL RE (RAID EDITION)
This one does not support GPL and is ACS-3 Rev 4

Both, 01YCBB2 & 01YCBB3 they are ACS-3 Rev 5
----------------------------------------------------------------------------------------------------
Crystal Disk Info This cannot spot other significant differences at 01YCBB2 VS 01YCBB3.

Standard
ACS-3 | ACS-3 Revision 5

Features
S.M.A.R.T. | APM, NCQ, GPL

But they are differences between the two firmware, it is clearly obvious that WD tweaked the table of statistics, at the column of Bad (value) some attributes were changed from the value 200 at new value 253.
In other words the Firmware RR07 this has tighten error statistics than the new.
This might be a minor detail, but it is there. :)

------------------------------------------------------------------------------------------------------

About the description RE now becomes obvious to that it translates to (RAID EDITION)
Now lets start over, we have Ultrastar engine, RAINIER this is relative to HDD electronic controller.

Every enthusiastic new owner of Gold Series, he is snicking around to find if the latest model has any addition of golden dust that it might increase data transfer speed's (Read / write ).

From the other hand if you considering to construct a RAID-1 array you should be very careful so both work horses to be of 100% identical specifications.
My first horse this is the latest Jan 2023 production, now I am looking for the second one. ;)
As soon my horse this arrives in Greece from Florida USA, I will be able to run benchmarks and say more about it.

Kiriakos GR:
Quick explanation about UASP (Serial ATA) ...

UASP = USB Attached SCSI Protocol

This is technology related to:
USB 3.0 / UASP External Hard Drive Enclosures
UASP USB 3.0 Controller Cards
Software support since Win8 and higher.

(When the HDD is in direct SATA wires connection with a motherboard, there no use of this technology.)
