I actually don't have any issues with old code as long as it works the way it's supposed to, which generally most code does until someone starts to 'hack' on it. I have a friend that does DOD level security clearance programming and he is very old school in proper structure, formatting, and commenting--and today even at these levels, the powers that be just want some hack job to 'get the job done' with the shortsightedness of a spider.

I especially think forcing UI changes because 'they are no longer in style' is a complete and utter waste of resources because people go to web sites to get something done, not 'oohhh and aahhh' about how pretty it is--and those that are doing this probably aren't contributing in a significant way to that site's revenue anyways.

Every brand is about defending itself these days, even when wrong--because it's all about the money. When the foundation of a company is based on questionable/flexible ethics, this corruptive outcome is pretty much inevitable.

Well not exactly. Old works just fine, the banking industry is built on the ISO8583 for sending transaction details. That was created back in the 1980s and has seen very few modifications. If it works then there's no need to change or add fluff. But that's not what we are seeing with eBay.

The problem that eBay has is that they are stuck between system overhauls to adapt to the growing number of users and features on the platform over the years. It's not just about the visual appearance. What I meant when I said pages stuck in the 90s, I meant they were one-off pages/features that are disconnected from everything else. As someone previously mentioned that their search feature is completely broken on the European version of the site. This is just an example of incomplete piecemeal updates. Most likely it's hacks upon hacks of a codebase in order to bring new features rather than revamping/refactoring old code to work with new features.

There's been a lot of organizational changes over the past few years with the company just struggling to remain valid and competitive. Most likely those changes resulted in the loss of talents, team restructuring, and ultimately incomplete projects with half gone live and the rest shelved.

For most people with home labs consumer SSD's are fine for boot drives. They also consume less power.

I never said consumer SSD's are not fine for boot drives - just that a 2TB consumer drive are not equal to a enterprise drive in any way - the only real thing you can say are the same is that they both use flash memory.
Enterprise drives usually have:

More write cache
More chips
Much better sustained performance
PLP
Often overprovisoned

Consumer SSD's are fine for a boot drive and light usage - just dont throw a consumer SSD into a discussion about an enterprise drive and say its just as good.

Try to do this with a consumer ssd

1k PB - that is insane - but how can you have written more than read - that seems like a very weird pattern :-D - or as a ZIL?

Probably ZIL, its an RMS-200 so not an actual SSD. Nevertheless its 8GB of excellent performance.

i386 · Oct 12, 2022

It's a radian rms-200, on ebay they are often listed as netapp/emc nvram/accelerator, they are the write cache for the big san systems

"Not an SSD" is an excellent description, since the flash on the RMS-200 is only written when power is removed from the card. Even with reboots for updates, you could keep the card powered for years, so it might only have a couple hundred GB of actual flash write.

I just received the 4 drives. 1 at 83% health, another at 84%, and the remaining two at 96%. The issue is that 3 drives cannot read more than 77-78MB/s, write seems to vary from 245-320MB/S Something to keep in mind if you are going to buy these.

Sounds like you got the $76 specials!

LOL! I fell for that trap card! I'll do some more testing.

Okay nvm. I goofed. CrystalDiskMark with the drives formatted as NTFS shows similar read/write speed matching specs. Using this other tool called Victoria HDD/SSD to test read/write over raw no partition and filesystem was what gave that speed variation. I will use a different tool to scan for errors.

So they're just like every other company facing the same issues with the same results, lol.

Added on you missed.

Some time ago I bought a couple of 960GB CloudSpeed ECO (gen I), they exhibit the same behavior, slow reads and about the same write speed as yours, but mine disconnect after a few tens GBs of sustained writes.

CrystalDiskMark on ISCSI zvol. These disks are current on RAIDZ.

Here are SMART readouts for these. None of them have Relocated sectors or critical error counts so that's good. Although I am not certain of what else to look for in the SMART data.

Some time ago I bought a couple of 960GB CloudSpeed ECO (gen I), they exhibit the same behavior, slow reads and about the same write speed as yours, but mine disconnect after a few tens GBs of sustained writes.

What benchmark tool were you using?

For those of you who bought these drives, I think these are the linux/windows tools for them:

I was looking at this but I saw that some people have issues setting the block size. I haven't given it a try to know the full details. Are there usually any performance benefits to upgrading the firmware? And can you also backup firmware?

I ended up having issues with two of the drives. One would drop from being detected and the other was incredibly slow randomly. They were both around 80% life. All of them had 3 years of uptime. The seller notified me that they found similar issues with a few other drives and asked if I would want to keep the remaining two or send them back. The two I had left were both 96% life but one had SMART errors relating to erase issues two years into its run time. I decided that it wasn't worth the deal that I received and just sent them all back for a full refund. The seller mentioned that they were recalling that specific batch to return to the vendor they had received the drives. Whether it's just to recover the drives realizing the mistakes made or they are actually part of a larger number of problematic drives, I don't really know but it wasn't worth the headaches down the road even if I wasn't going to store anything mission critical on them.

Unfortunately, always a risk with used parts. I've only had one issue with an enterprise samsung that performed at much lower level than benchmarks suggested but seller took it back no questions asked. I've had no issues with drives I've bought new, at least not in the first year of service - seagate 3TB comes to mind.
