60gb x25m g2 with read/write 4k of 10-13 mb/s?! help!

hey everyone. i did a fresh 7 install, in AHCI mode, did all the SSD tweaks, etc etc. drive is brand new.

i get (sry no pic)

Seq: R:251 W:1044K: R:13 W:124K64: R:143 W:65Time: 0.113 / 0.185everything is great and i did everything listed by intel and guides, etc. why is the 4k so low? faulty drive?anyone had this?thanks

everything is AWESOME. but the 4k is damn terrible. what could be doing this?other than my 4k these numbers are some of the best i have seen

Your 4k and access times are suboptimal but if you would notice that in real life is debatable. What mobo are you using?

Those results are not abnormal for a notebook/ laptop. If you put the drive in a workstation you would see an increase in the access time and 4k speeds.

Your access times of 0.113 / 0.185 should be in the order of 0.057 and 0.084. For some reason your notebook is adding latency which is effecting your access and 4k times.

hmm ok. any ideas what could cause a increased latency?

what if i changed allocation to 64K instead of 4k

and could i use something like acronis disk director to do this without formatting, or would this ruin ssd?

More than likely there is nothing you can do, apart from hassle ASUS and look for driver/ bios/ firmware updates. Changing the block size will not help. Whilst it is no doubt annoying that your ssd is not working optimally the difference is not something you will really notice outside of a benchmark.

thanks redux. i booted in safe mode and ran it again and the 4k went twice as good. 20/50

so it must be a driver thing

at least my ssd is working ok

what if the allocation units are offset. could this cause this latency?

if so and in general anyway, how do i completley wipe the ssd + recovery partition in order to set the alignment perfect on a fresh install. last fresh install i did the alignment is a liiiitle off.

thanks

Just a quick sanity check:

Intel does not make a 60GB X-25M G2. I assume you meant to type 80GB -- correct?
