[E2][BUGFIX INSIDE] Transfer speeds banchmark. Ohh my God, it's bad!

So, as you can see, no matter slow or fast is the card, it looks like that the speed is limited in something about 1066KB/s.
But, the same cards plugged direct on the USB (MicroSD to SD/USB adapter from OCZ Trifecta Kit) the speeds go up to 18888 KB/s read and 8969 KB/s write.
Conclusion: Use a card reader to transfer big files to the card, do not use the phone usb connection.

Good job on your effort. +karma.

I know all along that the Transfer speed through mass storage is A LOT more slower than through a card reader. But I never bother to benchmark it.. Hehs.. Now I know that the speed is VERY slow.

[keaglez]

Thanks for the test...

[vhugobr]

I was very happy with my new "super-duper-fast-card" and did these tests.
Then I became very unhappy... Can I laught or I cry? 

I did a test with HDPARM (at rokr e2 shell: "busybox hdparm -tT /dev/mmca1") and I noticed a change do 2.2mb/s to 3.5mb/s with the new card. So I can say that to the system, It had a gain of speed. It's much faster to load a game on GBA emulator.
So, worth the gain for the swap file. It's a talk of cost/benefit.

[Taurnil]

wow, now I can't stop thinking about a 150x SD card... WOOT!

[vhugobr]

Only 36MB/s read and 18MB/s write... Wow, it's amazing!
Here in Brazil things like ultra-speed cards, gadgets, and these geek things is hard to find, and cost much more than is USA.
But for the rokr e2 there isn't so much difference, the speeds change like plus 1mb/s, 1,5mb/s...

[keaglez]

My 60x card can get maximum 3,3mb/s on hdparm test... Not bad...

[konspirasi]

OMG i just know bout this thx to you

[irman5490]

I disagree... Using phone usb is a lot of faster than using Card Reader. Im using kingston SD 2GB.

[djceltic]

I'm with you irman5490, phone usb is way faster than cr

[vhugobr]

So, post your results. Maybe you modded/stock firmware is somehow faster than ours.
I did these tests with HD Tune Pro and with Sandra with 3 different cards. I'll try to post the graphics later.

[pizzadox619]

maybe your problem came from your 'kingmax'

e2's USB speed is fast

[vhugobr]

No, I tested my Kingmax and my OCZ Trifecta 66x. Both speeds are equal, limited at 1066KB/s on Rokr E2 Mass Storage mode.
Post your tests. I only believe in numbers/graphics.

See my graphics:

microSD Kingmax 1GB plugged on USB (via adapter, not reader)


microSD Kingmax 1GB on Rokr E2 (mass storage)


microSD OCZ Trifecta 2GB 66x speed plugged on USB (via adapter, not reader)


microSD OCZ Trifecta 2GB 66x speed on Rokr E2 (mass storage)

The graphs tells you everything.
You can see the tests attached in this reply.

[irman5490]

I think its the USB port. Im always using the back USB port than the front one. I will try to get the software to benchmark the SD card on next week after I buy a new hard disc. Things got really mess up with motorola modding files.

[vhugobr]

Maybe. I tested with Rokr Ultimate Firmware, no OC, no kaleidoscope.
I tested on front/back USB 2.0 ports, new motherboard, same speed.

My PC specs for doubts:
-AMD Athlon64 3800+
-Motherboard Asus A8N-SLI-SE
-ATI Radeon x800 XL 256MB GDDR3
-120GB+250GB SATA Disks
-2GB DDR400 Kingston in Dual Channel Mode
-Windows XP PRO

The specs are very very good, although it's not dualcore.
Put your tests here, I wish I'm wrong. (But seems not...)
