Yeah, those do not exist. I believe the quicker seek/access time of CF compared to HDDs make up for the low MB/s.

How about using a PCI-SATA card?

there is no PCI SSD. Also, PCIe SSDs only work as bootdrives if the motherboard supports the NVME Protocol. That was a huge issue with AM3 boards, pretty much none of them support it.

The best you could do is attach an SATA SSD on a PCI SATA controller (and hope they work together). That SSD would then be able to saturate the entire PCI bus and you would still only get less then a quarter of its peak performance.

BTW, it is not the trasnfer speed that makes SSDs desirable in daily use, it is the massively reduced seek times that offer the main benefit. You already have that with CF or SD cards.

NVMe support in Legacy BIOS : Clover or DUET + rEFInd.

Get a Promise S150 (TX2 or TX4) RAID PCI SATA controller and you will be set to use with an SSD.

I like this Promise 150 adapter, it says in a 33MHz PCI bus can do 133MB/sec speed, in 66MHz PCI 266MB/sec. I think i have the slower PCI in Asus P5A, but that would be still decent improvement from ~30MB/sec. Question is if Windows 95 OSR2 could be installed on it? Some info on internet says minimum Windows 98, other info minimum Windows XP.

So If It would not be compatible with Windows 95 and i would go with CF or SD card adapter, which adapter would be the fastest, which may could use the full 33MB/sec ATA speed? I see plenty adapters are exist, some crappy, some little better, so really dificult to find the fastest one, if exist. Also if i would buy high end SD card, not a 90MB/sec, but a 300MB/sec is the seek time would further improve?

VT642x has driver for Windows 95. Not sure if it's actually bootable...

I m reading there can be trouble with PCI IDE cards, since they using the same resources, like GPU, sound blaster, etc.
Or if i just buy a PATA SSD?

Is there a reason why you don't want to use a SATA SSD? I have bought a cheap 16GB SSD SATA drive and used a SATA/IDE converter to connect the SATA SSD to the motherboard's onboard IDE controller. It worked really well.

The Promise S150 SATA 1 controllers have Windows 98 drivers.
See here for drivers... look under legacy->SATA->SATA150->whatever
https://promise.com/us/Support

They also made a SATA II 150 controller that has XP as the minimum.

That is Windows 98 driver, but I will use Windows 95. I'm unsure if Win98 driver could be used on Win95. But I will save this option for my Windows 98 system with Pentium II overdrive. So thanks anyway!

Malvineous:
Yes, probably I will go with that option, with this adapter;
https://www.amazon.com/gp/product/B002SZDOM6/ … BMLJPZ2AL&psc=1
It has master/slave jumper. Hovewer i will be limited to ATA-33 speed, but a Pentium 233MHz MMX, maybe could not use any higher speed even from a PCI SATA drive.

Update:
So anyway, i have purchased also an a The Promise FastTrak S150 TX2plus controller and I ll see if work and which one will work faster...

What do you intend to do with the machine? Windows 95 with 33MB/sec read/write speed will be about as fast as it can be. The real slowdown with hard drives is the latency, so CF/SD/SSD will all solve that problem.

Win95 doesn't read from the disk enough to really benefit from anything faster than 33MB/sec. If your system has a working HDD LED, watch it when you boot up. It rarely stays solidly lit and generally tends to flicker with long gaps in between while hardware is initialised. All the time the LED is off, the system is waiting on something else to happen, so a faster disk will not speed up that LED-off time at all, because the disk is not being used during those delays.

Make sure your drivers support DMA as well (and you actually go in and turn it on), otherwise you'll be limited to PIO's (at best) 16MB/sec with very high CPU usage too.

PCI SATA controller seems overkill. I would definitely go with the pata ssd, although keep in mind most of those are 44pin you will likely need a 40pin to 44pin adapter. You can find 16gb 40 pin DOM modules that won’t break the bank but I doubt these are even capable of maxing out the ide spec.
