SSD 840 PRO True Specs?

by outerheaven87 / April 24, 2013 12:55 AM PDT

I've just purchased an 256GB SSD 840 Pro from PC World but the specs listed on PC World are different compared to the specs listed on the Samsung website.

I'm confused. What is the true specifications of the SSD 840 Pro? list the specs as:

Read speed Max: 530 MB/s
Write speed Max: 390 MB/s

Samsung list the specs as:

Up to 540MB/sec Sequential Read* Performance may vary based on system hardware & configuration
Up to 520MB/sec Sequential Write* Performance may vary based on system hardware & configuration

540MB/Sec Read or 530 MB/s?
520MB/sec Write or 390 MB/s?

Hopefully someone can shed some light on the confusion.

The only true spec is when it's in your system.

Since there are may variables from chipset, cables to OS and drivers you should see varying speed numbers. This can really upset folk that are new to the pc benchmark wheel of fortune.

PC World have actully listed it wrong.

I've noticed on the back of the Samsung 840 Pro box that I bought from PC world it says that it's the 128GB has read speed of 530 and write of 390 and the 256GB and 512MB varients of the Pro line up have both 540 Read and 520 Write as well as 100,000 random IOPS instead of 97000 found on the 128GB version.

It seems that PC World have listed the wrongs specs on the 256GB and 512GB Pro models of this SSD on there website.

My PC is fully capable of SATA3 at 6Gb/s

Proof is in the picture.

Changes in firmware changed the specs. Again, the only "true" spec that matters is in your system. What the picture could be is last week's shipment.
