Sorry guys, SanDisk CloudSpeed ECO Gen II SATA SSD - 1.92TB | eBay
Probably better to not use OBO, this will go fast.

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.Since corona, most components have not been their normal price, +20-30% easy.
Is there any kind of software so I can search like this on ebay?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
eBay permits you to set up a search with email notifications. Probably the easiest thing to do.Is there any kind of software so I can search like this on ebay?
Thanks.
What performance are you getting? I got two of these drives and the performance is garbage.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

Is the source code somewhere on the github?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
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.@hmartin did you try a different SATA/SAS controller? These drives have compatibility issues.
