What if BlueSCSI, but WAY FASTER?

I absolutely love the BlueSCSI, an open hardware and open source replacement for your old SCSI hard disks. However, we got some less than stellar benchmarks last time. Today, let's try and get as much speed as possible!

You misread the graphs at the end, check the scale. The SCSI2SD has a max of 2048 while the Blue only has 1024. The Blue is 975 while the SCSI is 1330. The Spinner is ~ the SCSI2SD

64TBW stands for 64 Terrabytes Written. It's an endurance measurement, how long the NAND will last before it begins to fail. Higher is better :)

Man, it warms my heart so much to see Mark Ruffalo's kid into retro tech.

Thanks for the followup - Great to see the tips helped you speed it up quite a bit!

[@pseudotasuki]

I see you're a man of culture. Kit is a magician.

This channel is awesome and partially responsible for my renewed obsession of acquiring and repairing retro macs that I salivated over in the 1990s but was way to broke to afford at the time. Thank you for covering topics like this. FANTASTIC! Much appreciated.

Is that a Kitboga shirt?

BlueSCSI saved my marriage!

SCSI2SD is based on (up to) 80MHz CortexM3 MCU with 64KB of RAM, BlueSCSI is based on (up to) 72MHz CortexM3 MCU with 20KB of RAM. Speed of BlueSCSI drops suddenly at 32k (sequential or random doesn't matter) when SCSI2SD makes much more consistent results. PSoC5LP doesn't offer much over STM32F103 we find in bluepill. It has advantage with programmable logic within I/O but that hardly explains speed difference (or rather - speed drop of BlueSCSI). My guess was and still is - 20KB of RAM is suboptimal. I wonder if black pill wouldn't make a huge difference. It has 128K of RAM (and slightly higher top speed as well along with more powerful core - Cortex M4)

Have more BlueSCSIs than I'll likely ever need at this point because it was cheaper for me to build a bunch of them from parts (I think I ended up with about 20) than to buy a few outright.

I wouldn't consider PNY generic. Amazon has a bunch of truly sketchy no-brand SD cards that may or may not even have their listed storage capacity.

I just noticed your shirt. Cue the Kitboga vs Angry scammer montage. "WHY DID YOU REDEEM!?!?"

[@costa_marco]

The t-shirt. 🤣

A Hello from Brazil! I don't miss any of your videos.

Love the shirt!

[@drywinddotnet]

Great vid! Now I wish I could get Blue SCSI working like that with my SGI Indigo.
