OCZ Vertex 450 256GB SSD Review - Benchmarks - Test System Setup and ATTO Baseline Performance

OCZ Vertex 450 256GB SSD Review
The rapid drop in 25nm flash availability and slow ramp up of 20nm production puts OCZ in a tough position. Vector availability is about to get scarce and Vertex 3.20 can't be profitable at less than $1 per GB. OCZ needs a higher profit product with the flash available today and it has to be faster than SandForce to sell, enter the new OCZ Vertex 450. (NASDAQ:OCZ)

Lenovo W530 - Mobile Workstation

 

 

We use two systems for SSD testing. The desktop runs a majority of the tests and the Lenovo W530 runs the notebook power tests as well as the real-world file transfer benchmark.

 

 

ATTO Baseline Performance

 

Version and / or Patch Used: 2.34

 

ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.

I know everyone likes to read me going on and on and on, but at some point we have to look at performance. Then again, this might be the second page you've looked at.

 

OCZ now measures their ATTO performance at a queue depth of 10, but even with our default depth of 4, we matched their marketing numbers. The read performance on our test nearly hit 547MB/s. The write performance peaked at nearly 525MB/s, but at the 128K block size.
