That $139 drive if you look at the feedback says it is only 16MB cache and not the drive listed in the title.
So here is something interesting. The official Seagate spec linked above says the model has 128MB cache. This drive says 16MB unless this is the wrong command.
Code:
ubuntu@ubuntu:~$ sudo hdparm -i /dev/sda

/dev/sda:

Model=ST4000LM016-1N2170, FwRev=0003
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=16384kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=7814037168
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes:  pio0 pio1 pio2 pio3 pio4
DMA modes:  mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6
AdvancedPM=yes: unknown setting WriteCache=enabled
Drive conforms to: Reserved:  ATA/ATAPI-4,5,6,7

* signifies the current active mode

ubuntu@ubuntu:~$
So, based on your findings of the cache size and the note on the $139 would you say these are infact mislabled (on the external device) and infact the same discs?

Wouldnt it then be worth paying the extra $15 for warranty?

Edit: obviously not now they are getting down to $100 range, haha.

The $139.99 drives appear to be OEM drives. I actually got a few serial numbers to check. So either way no warranty from Seagate. $139.99 means you do not have to shuck the drives. $124 means you can test the drive in the USB 3.0 enclosure and return in warranty before shucking.

Is ebay running any X off 100usd or more sales right now?
American Express card is running a promotion , spent $100 in Staples and received $25 statement credit. Check your AMEX online to see if you have the Staples offer. You must accept the Staples offer first before buying the Ebay gift card.
We have 4 AMEX cards, that allowed me to buy $400 Ebay gift cards for $300 at Staples.
In turn, I got 4 x Seagate drives.

So if they're an OEM drive I wonder who is buying them from seagate as an OEM, perhaps one of the larger hybrid storage array vendors leveraging these plus ssd's?

Could just as easily be any cloud vendor. It fits in pretty much any standard 2.5" drive enclosure which means it offers pretty nice GB/$ esp compared to any other option on the market. For most server installations these days, 10k/15k RPM drives are basically worthless, and the price for 4TB 2.5" is pretty close to the 3.5" 4TB pricing. I could see someone like say backblaze potentially looking at them to enable the same general capacity in 2-3U that they currently get in 4U.

Well I just got this today. Maybe that 2 years of 200GB OneDrive storage is not such a bad deal after all.

Has anyone run these on a HW RAID controler yet? I had one drop off an array earlier for no apparent reason, the controller couldn't even see it till I reseated the drive. Hopefully just a fluke and not something normal with these.

Not a HW RAID controller, but the initial backups I did from an M1015 HBA (reflashed IT); no dropouts there or in the USB caddy (FWIW I bought two and transplanted them into these).

Mine were also kitted out with 16MB of cache, although my drives were Samsung-branded on the label.

Just a heads up I tested the usb3 adapter with an ssd(850 evo) it appears limited to SATA2 speeds(which is fine i have piles of older 2.5 inch drives that i can use that with still)
