SSD Random Read/Write Speed Survey

[andilubio]

Considering it has sandforce controller i think its running rather slow...

 

[Filipek]

Maybe a stupid question, but does an internal SSD drive make any difference compared to a normal HD when writing to or from an external normal HD?
Or is the external normal HD still the bottleneck? And does anybody know how the performance are when the SSD is full or when it is like 80/90% full?

I don't know how often it has been said on MacRumors;

DON'T use XBench any more, especially not for benching SSD's.

The software is 5 years old and was neither made for SSD's, nor for any other modern hardware. It just doesn't scale with today's tech and gives completely unreliable results.

I did an XBench with my Intel as well; results from 160 to 300. You can hardly rely on the numbers you get from that software, so best you can do is to select it, and press delete!

Same for Quickbench?


The reliable apps are made for Windows:

maybe SATA 3Gigabit limited?

15" 2.2 with Crucial C300 Drive (firmware 006), fresh install...

Aja System Test puts more strain than Xbench, even got faster read speeds.

2011 MBP 15" 2.2Ghz 8GB RAM
Crucial M4 256GB SSD

The result is not as good as I expected

I wouldn't worry about it. Xbench doesn't reflect real world performance very well. And results are quite different every time I run it.

Here's my M4 256GB

Not bad.

I have supernice numbers I belive

Thanks, I purchased the MBP 2011 because of its Sata III which can maximize the read/write speed of the M4 (over 400Mb/s), but in fact it's only around <250Mb/s, so what is wrong here?

The benchmark

Try AJA system test instead.

This are my speeds.

This are my speeds.

Those are very nice. I have the same drive except the 240gb model. I hope my speeds are comparable to yours in a late 2011 15" 2.5ghz. I'll test tonight.

Damn!!

Makes my 470 (scoring a heretofore respectable ~300) look like a magnetic drive!
