Can only recommend those, while performance is ok, they are really nice with regard to heat. Got one installed in my Thinkpad as well. Too bad he doesn't ship to EU

They've been this price for well over a year.
Maybe not constantly, but this seems more normal than deal

Since corona, most components have not been their normal price, +20-30% easy.
Yeah seriously. DDR3 prices have shot up 40% or more from where I was buying at. 100% if you look at the threads where here where 32GB were being offered at $20/ea--now you can barely see a 16GB module for that price. :mad:

For me this was a deal, but I've only been monitoring the prices since April. I've included my results in the format of Title (ebay object id) and price. There weren't any 1.92TB SSD's available with a price lower than 125 USD, and all the items at 125 USD were from this seller only. And those were all sold in just a couple of hours, so that does sound like a deal to me ;)

The seller has 10ish of these drives for sale once in a while (month?). Wondering anyone already got these from previous sale?

Is there any kind of software so I can search like this on ebay? :)
Thanks.

Using the ebay search is indeed very easy to do, but somewhat limited, as you only receive the notification once a day. It's also limited to the country you've registered to. What I've done is using the ebay SDK and query multiple countries every x hours with all the searches that I want, store items that I've seen, and also inform myself when sellers are reducing prices of earlier seen items. Probably not how ebay intended to use it, but it pays off :)

What performance are you getting? I got two of these drives and the performance is garbage.

I get 190MB/s read and only 80MB/s write. There is nothing indicating a fault in the SMART logs, and I've tried a secure erase to no avail. They're running the latest firmware (ZR11RPA1). This performance is much less than I would expect, given the published drive specs (PDF).

Code:
$ sudo fio --name=randread --ioengine=libaio --iodepth=16 --rw=randread --bs=4k --buffered=0 --size=512M --numjobs=4 --runtime=240 --group_reporting
randread: (g=0): rw=randread, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T) 4096B-4096B, ioengine=libaio, iodepth=16

Is the source code somewhere on the github?

@hmartin did you try a different SATA/SAS controller? These drives have compatibility issues.
I've tried 2 Intel onboard SATA controllers (C226 and C210) as well as an ASM1166 based PCIe SATA controller. Performance is consistently poor across these 3 controllers.
