kraker Posted January 7, 2012 Share Posted January 7, 2012 I've bought a new corsair force 3 90gb ssd today and when I do a read test in hdtune reading speeds dips and comes back a few times as seen in this http://i.imgur.com/SMucI.jpg firmware is 1.3.3, ssd is plugged into sata 3 port, ahci and trim is enabled and I'm using intel controller. Thanks in advance. Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 7, 2012 Share Posted January 7, 2012 Ignore benches like this one, we don't use them and can't really comment on the results. Test it with ATTO. Link to comment Share on other sites More sharing options...
Synthohol Posted January 7, 2012 Share Posted January 7, 2012 hd tune is for hard disks, its even in the name :) there are no platters in an SSD so to me its like opening a bottle with a puppy. Link to comment Share on other sites More sharing options...
parsec Posted January 7, 2012 Share Posted January 7, 2012 While I can't tell from the graph what type of read is being tested (ie, sequential, 4k random, etc), no drive of any kind performs at a constant, single speed. The maximum speed specs that all drive manufactures state are for sequential reads of very large files. When a drive is reading smaller files, particularly multiple small files that are located in different locations on a drive, the read speed is slower, actually much slower. That is completely normal for any drive. That may seem illogical, but that is just reality. Also, if this drive is the OS drive, while you are running the test the drive is still serving IO requests from other processes running on the PC, which will affect the test results.
