Hello everyone. I have been building a PC for a client, which has a Samsung SSD 840 with 6B0Q firmware, installed as the OS drive. And i have some performance results that i would like to share, and ask if others are seeing the same performance on their Samsung SSD 840 drive. First off here is the windows 7 pro 64bit SP1 system (fresh clean install) that this drive is connected too. This SSD is connected to an Asus Sabertooth X79, socket 2011 motherboard. Plugged into the Intel 6Gbit ports, and setup in bios for AHCI operation, and write cache enabled in windows device manager. Newest drivers on Asus download page were installed on this board, such as. Intel chipset driver version 220.127.116.115 Intel Rapid Storage Technology enterprise Driver Software V18.104.22.1682. Intel Management Engine Interface V22.214.171.1245 The samsung SSD magician software ver 3.2 was also installed. As part of this build i have so far run two programs to verify the performance specifications of the samsung SSD 840 which are advertised as follows: Advertised Sequential Read Speed:Up to 530MB/s Advertised Sequential Write Speed:Up to 250MB/s Advertised Random Read Speed:Up to 96K IOPS Advertised Random Write Speed:Up to 62K IOPS The first thing I ran was the Samsung SSD magician v3.2 software that came with the drive. I ran the OS optimization section, which basically disables disk defragmenter, drive indexing and checks that windows is setup for SSD use, then i ran the benchmark. The results from this benchmark are as follows: Seq Read: 532MB/s Seq Write: 102MB/s Random Read:92K IOPS Random Write: 21K IOPS The read numbers match advertised, however the Write numberes look awful. I was wondering if anyone out there has run this Samsung Magician benchmark on their Samsung SSD 840 drive, and if they see the same results? I went ahead and also ran ATTO disk benchmark which gave me the following results which are closer to what is advertised Max Read = 564MB/s Max Write = 249MB/s I wonder why the samsung magician app reports different values for seq write compared to ATTO? I wonder if anyone else out there sees the same kind of results? Also does anyone have any tips on anything I should do to try and improve the performance of this drive on this system? I have noticed a few small pauses when doing things winthin windows, things like moving files, installing apps, or even loading into windows, which makes me wonder if maybe i should be using a different driver, or if there is some tweak i should perform, or if the drive itself has issues.
