USB Drive Speed

Using the test utility to evaluate speed of USB pen drives I got the following results:

Testing descriptions:
A: seconds taken to create one 10MB file (K/sec)
B: seconds taken to create ten 1MB files (K/sec)
C: seconds taken to create 1000 10KB files (K/sec)
D: seconds taken to create 1000 1KB files (K/sec)

E: seconds taken to reload one 10MB file (K/sec)
F: seconds taken to reload ten 1MB files (K/sec)
G: seconds taken to reload 1000 10KB files (K/sec)
H: seconds taken to reload 1000 1KB files (K/sec)

I: seconds taken to delete one 10MB file
J: seconds taken to delete ten 1MB files
K: seconds taken to delete 1000 10KB files
L: seconds taken to delete 1000 1KB files

Testing machines:
1: ARMini RAM disc
2: Virtual RPC Windows HDD
3: ARMini 96Gbytes Solid State Drive
4: Iyonix HDD
5: ARMini 16Gbyte Kingston Pen Drive
6: Iyonix 2Gbyte Pen Drive

Those Iyonix results are a bit slow – I’m guessing you aren’t using the improved USB drivers? If you install those then you should get results that are a lot closer to the ARMini USB.

I have the latest RISC OS ROM which is the latest USB2 spec, I understand. The USB drivers were a purchasable upgrade so I waited until the 5.16 ROM was available for free. No other items were required otherwise IyUpWych would have fetched them surely?

RTSupport I believe is a disc based module and it is also required.

You will find it in the latest ROOL hard disc image.

One other thing to bear in mind, though may not affect you given your comments about waiting for USB2, is that the newer modules in that hard disc image do not seem to alter those in the !Boot.Choices.Boot.PreDesk location and if you have any SCSI softloads there then it is best to check by overwritting them.

As the article explains:
“copy the contents of !Boot.RO510Hook.Boot.PreDesk.SoftSCSI to !Boot.Choices.Boot.PreDesk.SoftSCSI in your own boot sequence. You’ll also need to copy the RTSupport module from System.500.Modules to the identical place in your own boot sequence.”

Latest SCSI drivers are:

SCSIdriver 2.06 (25 Oct 2009)
RTSupport 0.06 (04 Aug 2011)
SCSISoftUSB 0.14 (24 Jul 2011)
SCSIFS 1.22 (14 Oct 2011)
SCSIFiler 1.21 (14 Oct 2011)

I just checked (and updated) mine, the latest of my files was from last year.

What has changed? (The performance increase from the previous upgrade was pretty dramatic.)
