Best disk speed app?

[RetroNinja]

What app do you use for testing/measuring disk speed?

Right now SysInfo is breaking on my TF536 since I've upgrade the mmulib to 47.9. The CF drive speed is plenty fast, it's just the speed test fails. SysInfo did work fine with 46.21. You can tell a difference between the version. I believe the big reason is the MuFastROM being enabled.

There is DiskSpeed (https://github.com/erique/DiskSpeed). It says the current version is 4.3, from 2023. My download is 4.2 though and is dated 1992.

DiskSpeed v4.2 does seem to work fine on my TF536 and OS 3.2. It's just a bit too geek oriented though. It runs about 10 test variations and displays the results of each test. At no point does it sums it all up or give an overall value. You know, like SysInfo.

Sysinfo is (or should be) well known for its inaccuracies in both CPU and disk speed (moreso for the latter), but along with DiskSpeed, SYSspeed can be used as a metric - a way to compare different devices (within the same hardware) against each other - but one needs to be aware of the way data is transferred and how this occurs at both the hardware and software level.

bdb nailed it. I often use SysInfo as a quick generic test just to make sure I didn't screw something up while testing, but SysSpeed is a much better general ballpark (especially with CF cards, write and seek performance can vary quite a lot). I say "ballpark" because the results aren't always consistent and can even vary a little between reboots, but it's a good general indicator. I use DiskSpeed frequently when testing CF cards, as a card that wins the SysInfo crown may perform considerably worse in other metrics. You might also check out RSCP and SCSIBench.

Also true about the interface - again with respect to CF cards and SysInfo, one card may achieve 5.5 MB/s on the A1200 IDE while the other only does 4, yet both return 9 on a SCSI-II controller.
