The Seagate one was reading 90 MB/s at the beginning - there is no hard 80MB/s limit and the port is correct. I just uploaded the Atlas 15k II screenshot because all three are in perfect shape unlike Seagate which is slowing down significantly after 30GB mark.... most likely some minor surface damage.
Btw - isn't the SCSI SE limited to 40 MB/s (called ultra-wide SCSI I think)?

I had a 531, which was the AMD version, and it was garbage. PSU couldn't actually make 300W and had no PCIe power connector, motherboard had ABYSMAL SATA performance and even the DVD drive didn't last long. Evidently the 530 was better!

You are right - SE tops at 40MB/s. Thanks for your correction.

Really lucky imo - $225.00 - http://www.ebay.com/itm/232236078190 😎

How much did you pay for the obsidian?

$200. No medusa cable though (I have two already though).

Got a NOS Maxtor DiamondMax 10 6L100M0 for my collection. This is a 100GB drive, based on one platter of the same capacity and two heads, running at 7200RPM with 8MB cache, and native SATA 1.5Gbps interface. (From my understanding, most SATA 1.5Gbps drives are using IDE-SATA bridge chips, and the DM10 is one of the minority that implemented it natively.) Pictured next to the DM17 6G160E0 I received a little while ago.

The SATA-PATA bridge design was popular when manufacturers debuted their first SATA drives. Maxtor did it, too, with the DiamondMax Plus 9. Hitachi did it with 7K250 and 7K400. WD also did it, but because of its non-generation-specific naming scheme, it's hard to tell solely from model numbers. Seagate did NOT adopt this strategy and used native SATA from the very beginning. I am not sure about Samsung.
Later most, if not all, manufacturers mated their 2nd generation SATA drives with native SATA port, such as your DiamondMax 10, 7K80/160/500, etc.

I'll post video/pictures later, but this weekend I bought a TI-99/4A setup from the original owner. The Craigslist ad is still up for now, but you can have a quick look here: https://denver.craigslist.org/sys/5996991791.html

This was the first computer I had as a child, and now I have a proper setup. The original owner LOVED this machine, and it shows in the MASSIVE amount of literature that came with the boxes. years worth of magazines, books, even the original credit card receipt from JC Penny (a home goods department store).

They exist in even lower capacities. I have a 15K 18GB Seagate Cheetah (model ST318452LW). Really high end when it came out.

havil's cheetah has the model number ST373455LC which indicates a 73GB 15k.5 drive. I guess the "#36" behind that model number halved the capacity. According to seagate 15k.5 ranges from 73GB to 300GB, so a 36GB variant is kinda odd.
ST318452LW belongs to the X15 36LP family which officially has 18GB and 36GB variants.
I reckon the last digit before "L" indicates the generation; 15k.5 is the 5th gen 15k drive and X15 36LP is the 2nd gen.

About Samsung, the 1.5Gbps SATA versions of the SpinPoint P80 (SP0812C/SP1213C/SP1614C) and PL40 (SP0411C) ranges used bridges. AFAIK, all 3Gbps-supporting SpinPoints are native implementations.

Good to know that. Indeed, I have never seen any SATA-II drive with a bridged PCB.

Pulled a Slimline 531 out of the scrap yard a while back. Had a Late 2013 WD Black 500, 2GB of Corsair ValueSelect, and an X2 5000 in it. Had a dead power supply though so i threw the motherboard into a full height eMachines ATX case along with a 500GB Seagate Barracude and 4GB of RAM (along side my 9800GTX+). That machine is suppose to be going to a friend that plays nothing but the Sims 3 and 4 as soon as I get the wifi card installed.

Its actually not the machines that are bad. Its the whole f****** platform. I can easily get by daily driving a 2.5GHZ Core2Duo from that same year. but the x2 was just such a horrible architecture. Even Windows 7's desktop was severely impacted to the point I would never be able to use it. Did some basic tests and it roughly trades blows with a 1.5GHZ Core2 Mobile Conroe. As for the SATA, keep in mind Dells hard drives have never been anything to write home about. I doubt the hard drive was fast enough to max out the SATA interface. The DVD drive mine had wasn't too bad. I actually threw it in my main. Currently is used for archiving my DOS games which I'm too paranoid to handle/open the boxes often since in my mind the slightest defect makes a games box worthless (To the point I overlook my entire game collection each day just to make sure the temperature fluctuations which range from the high 50's during the cold to the 90's when all my PC's are heating thing up in my room aren't making the boxes contract or expand in a way that would damage them). I've bought new copys of games over the tiniest damages that would still leave them in "high collectors grade" condition. Err... about the drive anywho it's actually not to bad. Mines some TSSTCorp model. It's possible Dell used multiple drive models in the 531 though.

The really nice version is the 530 w/ revision 3 motherboard. Takes all the way up to a q9650 and ahipped with a 375watt psu. The 531s I had was garbage compared to the 530's. Same issues as you, plus the 2.0ghz athlon64 ran slow and hot 🤣.

Bridged HDDs are known to have a bridge chip between the SATA data port and the HDD's main MCU

on this pic, you can see the HDD at the left (Seagate Barracuda 7200.7 SATA 150) is a native SATA implementation when the HDD on the right (Maxtor DiamondMax 9 Plus SATA 150) is a bridged IDE HDD

TBH that processor support is nothing to write home about either. Most Dell's (including there Optiplex 300 and 700 lines, particularly the SFF, DT and MT versions of the 330, 380, 745, 760, and 780 models) of that time supported up to the Q9650. My main gaming rig right now is a 330 DT with a 750TI, 4GB of PNY Optima DDR2-800 and a Q8300). Even alot of models that DIDN'T officially support the the Quad Core chip's would gladly accept them (Such as my 330). Dell used basically the exact same BIOs on each model within a family. Apparently the processor microcode is common among them. I haven't ran into a 300 or 700 series Optiplex that wouldn't boot atleast the lowerend quads. The PSU's are half-decent for what they are though I guess. I'm using the stock 290w in my 330 and after 3 years of constant at load (24/7 power on) it's running fine. In my experience the power supplys for there intel based machines tended to be atleast half passable for about 2-4 years after the Dimension 4000 series PSU fiasco. I'm guessing it was partly due to them wanting to avoid the same thing over again, partly due to the move to the BTX form factor for there cases (which makes installing dual slot graphics cards in them really fun.......). The power supply's in there AMD machines were, are, and always will be garbage though. But lets face it: If you're buying an AMD these days, performance and reliability probably aren't on your must have list. Until Ryzen anyways.......

Can a normal IDE connector be soldered into the rectangle above the largest chip?

i don't think so, that doesn't even look like an IDE connector at all

These CPUs finally came here

Celeron 1100 Coppermine (the fatest Coopermine-128 based desktop Celeron)
Athlon XP-M 1500+ 35 watt model
Athlon XP-M 1500+ 45 watt model

I bought many things last week-end !

Here is a complete IBM PS/ValuePoint 433DXS with a 486 DX33 with a socket 2 and a VLB port. There is some odd cache slot (it's not a regular COAST slot), but unfortunately it's not populated ... I haven't tested id yet, but I'm pretty sure it works (the HDD is a maxtor though, so this might be dead, but I have plenty hard drives so this is not a big deal)

I also got this incomplete HP Pavilion with a K6-2 300. The motherboard seems to be good. There is no AGP slot though, the GPU is integrated within the SiS chipset, but if I want to do 3D gaming, a voodoo 2 should do it.

Speaking of 3dfx voodoo, I've found this one

A 6MB Voodoo 1 with TV output, this seems really interesting ! Unfortunately it uses a proprietary passthrough cable which I don't have

I also did find this :

My first EISA system, yay ! Except for the battery, everything works perfectly, the original SCSI HDD has no bad sectors. I did not check if the P90 inside had the FDIV bug, but seeing how old is that thing, it might !

Next is this big tower :

It's a gateway 2000 tower that originally came with a Pentium 120 inside in the ATX flavour. It's empty now ... but I recently found on the internet a pentium pro system. If I can get my hands on it, this case would be perfect for this !

Other things I didn't show in photos :
A 486DX4 with an Aopen/Acer AP43 motherboard. FINALY A GOOD SOCKET 3 MOTHERBOARD WHICH WORKS, YAAAAAAAY !!! 🤣 I mounted it in my huge Ometra case that I had few month ago.

The original owner apparently had no idea how a 486 worked since the jumpers were configured to some random CPU which made the DX4 run at ... 33MHz ... (according to speedsys. However sometimes speedsys was also showing 30 or 35MHz, really odd ...) but now it runs at the correct speed. It works great, but I'm having some little problems with it for sound and maybe speed too, I will make a subject for it later.

I also had two socket 7 motherboard. One is VX based, it came with a Cyrix 6x86 PR150 and it works. The other is TX based, came with a Cyrix 6x86MX PR266 and it's not working for some reason 🙁 My god, why every single socket 7 board that I found isn't working unless the chipset is VX ? I now have three of them ! I made a topic about the TX board earlier as you probably have seen

I found also a cheap AT keyboard ... with a switch under it which lets me change to XT. I can finally control my 8088 ! yeah !

Next is an 8088 motherboard coming from an IBM PC 5160. I already got one, but knowing how old is that thing, it's still good to take.

The last things are some old floppies and a few uninteresting cheap expansion cards. (except for a matrox video card, but I already have many of them)

I have trouble in locating proprietary cache modules, too.

miro hiscore 3D, looks just like canopus pure 3D. I used to plug in my monitor's DVI port to the main video card and VGA port to Voodoo1/2, and switch between them whenever I need power from voodoo1/2. Not sure if it would work for canopus, but just FYI the canopus card can throw 2D input to your TV via S-Video out.
