You shouldn't automatically expect a "up to 150MB/s" card to write at that speed, none of the others do. "Performance may be lower depending on host device". It costs about the same as the other cards that do 93MB/s so I wouldn't be complaining.

you can't be more right. i know this cards are the best right now and that they're not optimized to work w/ML nor ML RAW recording; for now this performance is expected from the best CF cards out there on ML (which it's not even alpha). so, basically i post it to share results from this higher end CF cards, lots of people wondering and commenting just by reading product description and expecting (like me) some exclusive performance but that's not happening... yet hehe.

this cards are gonna be w/me for a long time, they're really tough and I shoot a lot in hot-humid weathers, I'm really lucky to be able to afford them and can't complain anymore

it wouldn't hurt to have a c300 around right now....

cheers!

This is the first I see someone show these type of CF write speeds benchmarked via CrystalDiskMark.  Are you getting this consistently? Curious to know the source of the bottleneck since the DMA controllers (EDMAC) are capable of 700 MB/s.

I've tested it two times and got the same score... this cards are advertised to run up to 150mb/s. i was expecting 145-148mb/s at least.


I have two 32gb 800x Lexar, and they benchmark really close of the advertised speed, in every app (ML, CDM and BM SpeedDisk).

sorry for the HUGE pictures.... 

Can you do a benchmark in playback mode?

whoa, nice! still... 120mb/s, that card can do higher than that...



the thing that's bugging me is the fact that both ML benchmark and BM Disk Speed Test score virtually the same mb/s, but CrystalDisk Mark score way higher... why's that? 

I recently purchased 2 of this babies, hoping to get at least 30p 1080p, but I could not. 

When warmed up, I get no more than 90-93 mb/s. Why?

Here are my benchmark test:
Out of the box


Using Usb 3 Lexar card Reader (w/UDMA 7 firmware update):


And here's the strange result I got w/CrystalDisk Mark;  sweet baby Jesus 137mb/s!!


I really don't understand what's going on here... I'm I doing something wrong? I would really like to stay with this card, they don't come cheap, getting that 137mb/s in ML would be a blessing and this cards are really reliable.
