oldmanpushbmw Posted February 1, 2012 Share Posted February 1, 2012 i dont have single ssd test result now,but i test atto disk benchmaek before single GT120GB max write is 515mb/sec and read is 557mb/sec so my raid 0(2xssd) result is write1094mb/sec and read 1091mb/sec.why the write fast than single?(515x2=1030mb) Link to comment Share on other sites More sharing options...
Toasted Posted February 1, 2012 Share Posted February 1, 2012 Max Sequential Read/Write (using ATTO Disk Benchmark)555 MB/s sequential read — 515 MB/s sequential write http://www.corsair.com/ssd/force-series-gt-ssd/force-series-gt-120gb-sata-3-6gbps-solid-state-hard-drive.html Click Tech Specs. -What are you trying ask?

Wired Posted February 1, 2012 Share Posted February 1, 2012 It's just a glitch in ATTO most likely. Link to comment Share on other sites More sharing options...
Synbios Posted February 7, 2012 Share Posted February 7, 2012 It's just a glitch in ATTO most likely. Yup, due to caching usually. Link to comment Share on other sites More sharing options...
parsec Posted February 9, 2012 Share Posted February 9, 2012 If this is on an Intel chipset board, using the Intel RAID driver, and the Write-back cache option is enabled in the Intel RAID GUI, any SSD I've ever tried in RAID 0 has much better write performance in bench marks. When using ATTO, which is usually the best case situation test, getting more than twice the write speed of doubling the write speed spec of a single drive does not surprise me. Man-pushing-BMW, (aren't you tired yet?) The Write-back Cache option of the Intel RAID driver uses the RAM memory of the PC as a buffer, so while the SSD is writing data, the new data coming in is put in the RAM memory, and then sent to the SSD when it is ready.
