I have a san disk SSD plus 240gb and here is a picture of a benchmark I ran, apparently my write times are horrid. Anyway I can fix these because at this point the ssd is slower than my 5-6 year old mechanical HDD in terms of write speeds. Or anything I can try to see if it might be a problem? According to the software that came with the SSD my firmware etc is fully up to date.

- are you using SATA 3 cable, they have a metal clip on them, the SATA 2 cables don't
- did you do a full format on the SSD, a quick format or no format? Slow performance has been reported on SSDs that haven't been formatted before use. If you decide to format the drive again, of course the data has to be copied off first.
- are the files compressed (like zip files or movies). This can affect write speeds.
- is the filesystem compressed NTFS? This can slow down some disks.

About 2 years old, maybe a bit less, has 96% life left according to the software it came with, as for how full it is,136 gb use 86 gb free atm. Its ALWAYS been really slow in terms of writing though.

Well, there goes that theory...lol

Firmware update, maybe? What does the Sandisk SSD Dashboard say?

If another port and SATA cable make no difference then perhaps the SSD has a problem within itself somewhere that is causing slow performance. In other words a working but a partially crippled product. Others might know where that could be in an SSD. The flash controller perhaps? Or there could be an issue with the motherboard somewhere.

If you have a known good SSD you could add that to your system and see how it performs. If it does well then the original SSD might have problems. If it doesn't then the motherboard may have issues.

yeah I've tried 2 diffrent benchmark softwares and both report about the same. Tomorrow I plan to switch the sdd from sata port 1 to sata port 3 and see if that makes any diffrence at all.
