Slow ATTO: Corsair Force 3 SSD 240GB rev. 1.3.3 on MacBook Pro 8,2 (early 2011)


Recommended Posts

Hi fellas,

I'm experiencing under 400MB/s performance on my MBP both in Mac OS Lion and Windows 7.

Under Mac OS it does not go faster than 260MB/s!!

 

* Both systems state the disk runs at 6GB/s SATA III.

* Windows 7 is fresh install.

* Latest firmware update v1.3.3 was already in place when I bought the SSD.

* Mac OS did not enable TRIM by default, I ran the test, saw it was slow, I enabled the TRIM with TrimEnabler and still it's slow.

* EFI is updated to latest available from Apple (v2.3):!:

 

Have a look at the screenshot attached.

 

Please advise why I am getting so slow IO to my brand new SSD!

 

Thanks

Those are definitely faster than SATA II speeds, so it is definitely running on SATA III.

 

The 550 MB/sec was taken on a P67 Intel desktop chipset. I wouldn't expect a laptop to get the same speeds. I recommend you search around these forums or perhaps benchmarking/review sites to see what kind of speeds your laptop is capable of.

If XBench tests differently than ATTO then you can't compare the numbers. I concur with Synbios, see how others test on their MacBook Pro 8,2 (early 2011) and see what speeds they get. There are SATA controllers out there that support SATA III, but at the same time physically cannot support the max speed of SATA III.

Hello,

I have the same problems. The Corsair Force 3 is unusually slow in my MacBook Pro(early 2011).

Is there a solution to the problem?

Looks like you're a little low from the review benchmarks I've seen (they max out at 320 under some of the xbench tests).

 

Anyone have EFI 2.2 or higher?

For those with a MacBook Pro 15″ or 17″ model that has SATA 3.0 6Gb/s link capability reported, it is very important to note that this EFI update does not appear to have resolved reliability of using a 6Gb/s drive in the optical bay. If you have a 6Gb/s optical drive bay connnection and are using a product like our Data Doubler, we still recommend only using a SATA 2.0 3Gb/s drive in that bay. MacBook Pro 13″ owners who find 6Gb/s links in their optical bay are not experiencing issues with 6Gb/s drives and this update doesn’t affect that usage.

Earlier this year, we noted that users of Apple's current MacBook Pro attempting to install third-party 6.0 Gb/s SATA 3.0 solid-state drives had been experiencing performance issues apparently related to interference issues between cables inside the chassis.

My system ran EFI v2.3 while benchmarking, the latest available from Apple as for now.

My results are still valid (and unsatisfactory). :(:

This sucks so much, I can't believe it's just about the electric interference of the SATA III cable because this affects not just MB PROs but also other Apple products.

 

In fact, it does not make sense to justify the fact the SSD can reach just a miserable half of the nominal speed just saying it's a laptop system.

 

This issue really stinks of software flaw. I recommend Corsair should investigate this easily reproducible case by sniffing the data flow through the SATA bus on a Mac.

 

i have force 3 and iMac 12.2 ssd speed is r/w 200/180

What benchmark program are you using on Mac?

 

If its Blackmagic Disk Speed Test, note that version 2.1 benchmarks using uncompressed data.

 

Some SSD's use hidden compression when writing data to make their benchmarked speeds appear faster. Disk Speed Test will now measure the true speed of these SSD's so you know if they are suitable for high quality uncompressed video capture.
