Hi all! I have an 840 Evo 120 GB (latest firmware, OP and RAPID enabled) on my Aspire 5750G with Windows 8 and it was really fast... but a few days ago after a bsod (it dealt with Daemon Tool) and several restarts, my SSD dramatically slowed down in all its tasks. After looking everywhere for a solution, I decided to write here hoping there's someone who can help me! I think that some SSD auto-protect settings has been enabled since the bsod and now performances are really poor; or worse it could have been electrostatic discharge.. what do you think about? Here's some benchmarks.

1) pciide driver / Test ran in safe mode (30/Jun/14)

2) iaStorA driver / Test ran in normal mode / Intel RST drivers: 11.5.something / (30/Jun/14)

3) iaStorA driver / Test ran in normal mode / Intel RST drivers: 12.9.0.1001 (30/Jun/14)

And these are two magician tests:

1) 17/Oct/13

2) 30/Jun/14

Results are pretty clear... I don't know what to do guys, one moment all works perfectly and the day after the breakdown. Help me!!! :sarcastic:

P.S. Sorry for my English

-confirm that your drive has free space on it (maybe 20%)
-confirm that the cable connections are good, maybe move the connector to another port. (not a likely cause of your problem but check) Then boot your system into the BIOS and confirm the BIOS mode for the SATA controller is correct and leave the system powered on but just in the BIOS screen for a few hours. The SSD will start running its clean up routines after about 5 mins of idle in the BIOS.

the SSD will have its own internal clean up routines that run when the drive detects that they system is idle. They might start 5 mins after idle, problem is that some system put the drive to sleep after 10 mins of idle and the drives clean up routines get starved and they just back up. providing power to the drive while not in use generally will resolve this type of problem.

could be other issues but give this a shot and see if it helps.

Hi johnbl, i had 14 GB ~ of available space after the BSOD (pagefile drained so much space), however I cleaned up a bit and now there are 38 GB ~ available of 100 GB (11 GB are dedicated to OP). There are no cables (it's a laptop) but I connected the SSD on a desktop PC and nothing changed. I launched the BIOS as well and I left all that way for about 4 hours but it didn't happen anything.
I also changed SATA driver from iaStorA (Intel RST) to storahci (standard): though sequential r/w values are increased access times and 4K scores are basically the same.
The OS is Windows 8 (clean install), SATA 3 and AHCI have been always enabled. I thought of high temperatures but they are not higher than they were before. I'm worried this could be a physical damage due to power-cycles during the BSODs..
Just to be clear could it be possible to put the SSD in a external box and connect through USB to the laptop in order to provide power? Could anything change?
