My media server has a 128 gig C: (Samsung 840 Pro) and a D: which is a RAID1 consisting of two, 4 gig drives.
The last few weeks, when I un-RAR a 5+ gig video file from the SSD to another directory on the SSD, 7-Zip tells me the write speed is a pathetic 12MB/sec. This use to be 100MB/sec.
Un-packing that same file to the RAID array, it writes at about 75MB/sec. Write caching has been turned off on my SSD since I installed Win7 on it a year ago. This slowness started about a month ago. I've read countless articles about a bug in the 840 that talks about this (does it effect the Pro?) and used Drive Magician 4.7 to "optimize" the drive and the problem remains.
Looking at the screen shots above, is my SSD ready to die?
On a side note, since I'm using RAID, Drive Magician is freaking out communicating with my drive. Other than pulling the drive out and slaving it on another system to work on it, will I harm my RAID array by switching the BIOS to AHCI, booting Windows and doing whatever then switching back to RAID? I could have sworn this WAS possible but you needed to load some drivers first and make a registry change else Windows won't boot.
Anyone have the links for that?
