The Lexar 1000x and Toshiba 1066x are the top performers.

A1ex have you done the funky graph on the Toshiba benchmarks I submitted?

hey guys, so what is the fastest CF card for 5D2 shooting? I have no clue how to read all these numbers here...

just one quick note, the Lexar 1000x 16GB is much slower!

Don't forget Hoodman Steel is the top performer too!

Do you ever get dropped frames in 1080p with the Toshiba 1066 64gb card?

@ 1080p sometimes the buffer fills after a couple of seconds on the first recording but after that it's rock solid. I'm shooting mostly 1920x840.

Yea, I figure that initial recording frame drop happens regardless of card speeds. Good to know its solid thereafter though! Thanks for the info! I'll pick one up!

There's been at least one build in the last week that didn't drop frames on the first recording, damned if I know which one.  :'( Shooting is going really smoothly for me, I wish I could say the same about post. Adobe camera raw just wasn't designed for moving pictures.

Re: Card benchmark - what's the optimal write buffer size?
« Reply #136 on: May 30, 2013, 09:49:08 PM »
Hey a1ex and g3gg0, there's something that maybe you're missing. All flash cards (SD/CF/SSD/etc) have a fixed erase block size.

If there's no partition and the card is just formatted with filesystem then it is ok. But for those who have a partition table on them, the partition must be aligned with EBS to have optimal performance (See articles on partition alignment for SSD)

All partitions of the cards I've tested were misaligned out-of-the-box. Besides Dane-elec and Sandisk I couldn't recall the other brands. I couldn't recall the numbers but I did see performance improvements.

Instead of trying to find EBS for all cards, I suggest aligning the partition at 1MB, so it should fit almost (if not all) EBS.

An utility to check alignment: http://www.tcpdump.com/kb/os/windows/disk-alignment/all-pages.html
(Or using MS System Information - msinfo32.exe) http://whirlpool.net.au/wiki/checking_ssd_alignment

Instructions for Windows XP here: http://support.microsoft.com/kb/929491
Linux users should set fdisk to show entry/units to sectors and create a partition with starting sector 2048.
Of course you can use any partition manager to move/resize the beginning of the partition.

Regards,

Rodrigo

Sorry for this noob Question, but I do not understand how you can create an align partition that can be usable in the camera, as every time the 5D read the new partition (with a good alignement), it detect that partition wasn't create in the DSLR, so I'm obliged to format the CF inside and the alignement goes out... I'v try many time, using the freeware "active partition manager" and I very don't understand what's wrong ...

I'm very disapointed as I have 2 Komputerbay x600 wich max up at 30Mb/s with bad alignement. Hoped to gain some biterate with alignement...  :'(

There's something I don't understand, I try my Komputerbay 600x (just formated in the 5Dmk2) on cristal diskmark on an CF reader USB3, and I got 61MB/s with 4000MB test files but 0.5 MB/s with 512k files. When I try benchmarking in ML menu, I maxed 25-30MB/s

My question : Is there difference or inconsistency between caching RAM / controller on the 5D hardware as I see many people with mk2 maxing at 60/70 MB/s with some KB, or is it only the CF ?

really Sorry for this noobesque questions  :'(

Komputerbay write speeds aren't consistent, it's a lottery.

from a amazon comment on 128 GB Komputerbay card


 "The tech support person was great to talk to, here is a bit of inside info he gave me. They use micron/crucial chips on the 128GB card and a MSI (I think it's LSI) controller if I remember correctly. He said it the same as the Lexar 1000x cards. The Komputerbay smaller CF cards use samsung chips."

So maybe the 128GB is not a lottery and the price is between the Lexar 32 and Lexar 64.

What do you think?

I don't know if I should go for a Komputerbay 128GB or a Lexar 32GB 1000x

What do you think?

I don't know if I should go for a Komputerbay 128GB or a Lexar 32GB 1000x

Hey dude, it is better for you forget about Komputerbay 128Gb
I have bought a new one from Amazon and this is the score



YOU CAN'T record RAW 1920x1080 16:9 25 Fps

I'll go with refund and I'll use my Lexar 32Gb (record flawlessly raw 19820x1080) until CF-to-SSD will be ready

I made a quick benchmark of a SanDisk Extreme 45MB/s. After formatting it to exFAT file system, it gives stable 20+MB write speeds.

@ all the people using Transcend cards operating near 83 MB/s:
Have you already tried the "AutoFormat" tool that Transcend provides to low-level format the cards?
http://de.transcend-info.com/support/DlCenter/dllogin_t.asp?Link=|support|dlcenter|software|AutoFormat.zip
I´ve read one report of a ML user on amazon.de that autoformat did solve his problems and he was able to record 1080p afterwards.

Best wishes,
Andreas

I never had to use any special format-tool. I worked straight away
