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.
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?
PCWorld.co.uk 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.
