ATTO or AS SSD for real world performance...

post #1 of 5
Thread Starter 
So I'm trying to figure out what gives me a better benchmark for real world performance. Atto or as ssd? My mushkin chronos drive will only do like 200mb seq and 18mb 4k reads yet on atto they get well over 500 on the read and 170 4k and like 500mb/sec writes...

From the AS SSD perspective the drive looks absolutely horrible! Like one of the worst ssd's ever, yet on atto the drive looks like one of the best... It kills my Samsung 830 series write performances by like 4x. Now I've read that atto uses compressed data and as ssd is uncompressed data, which is more real world, gaming and just typical hard drive usage?

Thanks guys! I've tried to find an answer for this and I haven't come across a definitive answer.

ATTO shows best case for SandForce while AS SSD shows worst case. Actual real world would likely be somewhere in between assuming drive is used for OS, etc and NTFS compression is disabled.

Try using AS SSD compressibility test. Actual average throughput will likely fall in the 40-60% range.

There is no benchmark for real world experience , that is up to the enduser to notice the difference in performance . I believe it is abouth the acces time and not seqentieel loads .The ASSD acces time benchmark can give information abouth the state of the ssd and acces times makes the pc respond very fast .For gaming on high hig end it is the best you can have ,it is al abouth removing latency from the pc to make the pc as real time as it can be .Afcourse is seqentieel load a thing to notice when loading , but it is ms difference in reading a 180 MB file from 180MBmaxread ssd or 750MBmaxread ssd array. But that smal diference begins around loading a 32k file to appear ,anything higher is ms faster .The os writes and reads QD1 4K a lot but not a lot 32k + ,and the pagefile writes 64k. But you can raid the page if you got more ssd put on every ssd a pagefile and windows writes in raid 0 to the pagefile thumb.gif

Raid the page smile.gif

PCMARK VANTAGE HDD SUITE is better fo real world performance,then AS-SSD and CDM.
Also on tweaktown you can see PCMARK VANTAGE HDD SUITE benchmark on empty SSDs and with data( 25%, 50%, 75% Full States and Dirty / Empty Test)

I also saw this first time.It seems that rapid is pumped only in AS-SSD and CMD,but when it comes to PCMARK:

Anvil's Storage Utilities with the compression set to 46% from settings. Quite nice middle ground. thumb.gif
http://www.xtremesystems.org/forums/showthread.php?273661-Anvil-s-Storage-Utilities
Open ASU from AnvilPro.exe, click Settings, on the left side change Compression: 100% (Incompressible) to 46% (Applications) then click Save settings on the bottom right and then on the top left click Benchmarks -> SSD Benchmark.
Now ASU will do it's thing with 46% of the data being compressed when you run the benchmark.

This thing must be the best benchmark utility out there. At least in my honest opinion.
