please report back if firmware changes performance benchmarks.That looks wonderful, thank you!
I guess there are defective Eco II's out there.
My "slow reading" Eco II drives all had ZR06RPA1 firmware. My normally performing Ultra also has ZR11RPA1.
I guess i may try another pair of Eco II's; and try upgrading firmware if it's slow reading.
Same boat, don't need them... been thinking about it. I'm wondering if I wait another 6 months or so 4TB drives may come up around this price range.Now, ebay is hammering my phone with dire warnings that most of the listings are "almost gone!" and I need to "get your's before its too late!".
Just checked my 12 CloudSpeed Eco II (SDLF1CRR-019T-1HA1): from 354 MB/s to 397 MB/s with 9 out of 12 being over 390 MB/s.If anybody has counter-example with Eco II sequential read speed in the expected range (300-400MB/sec) i'd love to see it, since those are now cheapest drives available...
Care to share where you found it?I hunted around and found firmware ZR08, applied it to my Eco 1.92T, rebooted, and so far 150GB into the same dd sequential read test it's doing 360MB/s very consistently. Not sure what the previous 290MB/s was about, perhaps it had a bunch of internal cleanup to do after the full disk worth of sequential writes, I will re-test with ZR11 after this run finishes.
