Here's my DIY ArmMiniX

Nice!!!!!

I like the case Chris, well done! :)

Looks cool.

I see you have an SSD attached. What’s the performance like when used with RISC OS? How fast is boot to desktop?

On my Minim with E-SATA attached SanDisk 120GB I get 73MB/s read and 76MB.s write which isn’t great. It’s better than the same SSD with a USB3 to SATA3 adaptor which only does 19MB/s and 17MB/s. On a Linux Raspberry Pi 4 with the same USB3 to SATA3 adaptor, the 64MB version of drive manages 384MB/s and 171MB/s. The maximum performance of the drives directly connected to a PC motherboard SATA3 interfaces is; 64GB 404MB/s and 186MB/s, and the 120GB slightly faster at 417MB/s and 322MB/s.

The Minim’s RAM disc (uncached memory) manages 147MB/s read 391MB/s write, Memphis (cached memory) does 406MB/s and 399MB/s. Which tells me the maximum performance of the filing system stack, isn’t getting anywhere near the performance of a decent SATA3 SSD such as the 512GB Samsung EVO 850 which does 506MB/s read and 494MB/s write (when new).

Some SSD drives have on board RAM so that writing only slows down as the drive and the RAM cache fill. Sometimes therefore the performance figures can be misleading.

Are there any disk benchmarking tools for RISC OS? It’s faster than the SD card I was using previously. I also feel like my data is safer on the SSD. Bootup time is 15 seconds.

I found RISCOSmark.

Are there any disk benchmarking tools for RISC OS?

You could try Discspeed by Matthias Seifert – back in the days when we measured the speed of SCSI podules, it was the only one achieving reproducable results.

http://www.software-evolutions.de/download/free/

Not sure if it is 32bit compatible, last time I tried was perhaps in 1997 or whenever I got that Eesox SCSI podule…away from all my 32bit machines at the moment so cannot test myself.

I’ll give it a try thanks Steffen. Looks like I’m getting about 14MB/s with RISCOSmark

There are some ROMark benchmarks here

!Speed is a legacy disk speed analyser which does run on a Pi3 under Aemulor. Not sure how accurate it is, though on my setup it agrees fairly well with RISCOSmark.
