I use google to find out what they have internally and their pdf datasheets, and review websites. Intel 320 is SATA II and used intel controller, try this. https://en.wikipedia.org/wiki/List_of_Intel_SSDs Curcial M500 is also SATA II and good choice to use. Usually has Marvell chipset controller, I …

These that new will still have AF using 512 sector emulation. Could be these drives are SATA III, have you tried older one that supports SATA II or I, try this with old hard drive if you have one on hand for a trial? Cheers,

Ahh. 4K sector support or "advanced format" aka AF, This can be a issue, As long as the SSD supports 512 byte sector support will work. Needs older SSD pre-4K / pre-AF SSD. This means before 2016 or so. Also Micron branded SSD (usually went with OEM computers), but can be purchased via ebay. I focus …

My case does use rails, not only to keep the drives in place, but also it's the only way that 5.25" drives can even be mounted in the case as there's no screw holes. So I need to find more somewhere, or 3D print them. Anyway, we know that the case is made by Intel, but what is the model? Does the …

I have four old servers lying around the house. As they are heavy power-hungry breasts, I rarely play with them (and I'm not even sure they are functioning correctly as I write this). Is there any scenario where they might be fun to play with, something that can't be done with "ordinary"retro …

Keep in mind LED current 220 ohm resistors at 5V across both in series is about 22mA. Integrated chipsets might drive high or pull low much more current but these resistors serves to limit the transmission line currents, ringing (think of as echo) and help with keeping heat dissipation of the …

386SX benefits from cache so much, ditto to 386DX with cache. I had compaq LTE 386s/20 which is a real 386SX 20 CPU with compaq custom chipsets one of them containing 8K cache. When I swapped 386SX for AMD 386SX 25 or more and changed crystal oscillator. Performed even faster. Cheers,
