Look at the code numbers on the drive. The "R/N" code is a "Regulatory Number" aka "Agency Model Number" for government safety certification. "US7SAP140" corresponds to the WD Ultrastar DC HC520 7200-RPM SATA interface drive, HGST model numbers WUH721414ALE6L4 and WUH721414ALE6L1. In other words:
How to Read Model Numbers: WUH721414ALE6L4 – 14TB SATA 6Gb/s 512e Base (SE) with Legacy Pin 3 config:
W = Western Digital
U = Ultrastar
H = Helium
72 = 7200 RPM
14 = Max capacity (14TB)
14 = Capacity this model (14TB)
A = Generation code
L = 26.1mm z-height
E6 = Interface (512e SATA 6Gb/s)
(52 = 512e SAS 12Gb/s)
** 512e models can be converted to 4Kn format and vice versa
y = Power Disable Pin 3 status(0 = Power Disable Pin 3 support
L = Legacy Pin 3 config – No Power Disable Support)
z = Data Security Mode
1 = SED* : Self-Encryption Drive TCG-Enterprise and Sanitize Crypto Scramble / Erase
4 = Base (SE)* : No Encryption, Sanitize Overwrite only
5 = SED-FIPS: SED w/ certification (SAS only)

WD140EDFZ R/N is also WD140EDFZ. This goes back to the drives essentially being the same even though WD has them rebranded from some reason. EDFZ drives are WD Ultrastar DC HC520 7200-RPM SATA if you go base of the R/N Number on the EDFZ.
If you look up the R/N Number on the Drive (US7SAP140) it is linked to WUH721414ALE6L4 Base (SE) Not supported / WUH721414ALE6L1. indicating the drives were originally 7200rpm drives, but have been slowed down to 5400rpm for the purpose of Easystore.Sgt_Strider wrote: ↑ I quickly looked at the pictures and I don't see 72 anywhere. How can you be sure it's 7200 RPM?
The prices of HDD have been slowly coming cheaper as each year passes which is great for us Canadians, even though we are still that much more expensive vs our counterparts over the boarder. Hopefully when the time comes for you to add more drives or replace drives, you'll have much better options at that point.game_fanatic wrote: ↑ Man seeing these deals makes me wish I waited to set up my NAS. I ended up with a DS1019+ w/ 5 x 10TB HDs at $230 each. Could've spent an extra $150 and ended up with an extra 16TB
Yeah that's the dream! 40TB should last me a couple more years (I hope), by the hopefully we'll see 14TB-16TB drives hit $200!Bleachway wrote: ↑ If you look up the R/N Number on the Drive (US7SAP140) it is linked to WUH721414ALE6L4 Base (SE) Not supported / WUH721414ALE6L1. indicating the drives were originally 7200rpm drives, but have been slowed down to 5400rpm for the purpose of Easystore.

I've been fortunate to have bought 2x12TB around the price point of $230-260. I'm up to 24TB now, looking to purchase another 12-14TB and push myself up to 36-38TB. Just when you tell yourself, "I should be good for now", probably could use another one. My ever-growing media storage just grows as year passes. lolgame_fanatic wrote: ↑ Yeah that's the dream! 40TB should last me a couple more years (I hope), by the hopefully we'll see 14TB-16TB drives hit $200!
How would you say these drives stack up vs the Seagate Exos drives? I'm trying to compare the $199 10tb Seagate Expansion that was an Exos inside vs this drive to shuck and use in NAS.
I made an executive decision to cap my NAS at 10tb drives for now, including parity. While these larger drives are very good TB/$, the parity rebuild time and simple fact that it's a ton of data to potentially lose in a single shot is a turn off for me. That being said I've got 24 bays in my NAS so I do have some flexibility in terms of drive bay real estate.Rollingsound wrote: ↑Just spent all the time upgrading parity drive to 12tb, damn, shoulda waited and gone for 2X 14tb instead...
If u can return and get this then do it.spartan217 wrote: ↑ I already jumped on the WD 12TB for $230 at BB couple weeks back, is it worth returning them for this deal....?
