[SOLVED] my brand new mx500 ssd giving very poor copy paste speed

[eziowar]

hi, my cpu i5-4670k, gpu - zotac 1050ti mini, mobo- gigabyte z87x-ud3h, bios version F10b, psu corsair cs650m , ram 4x4gb @1600 mhz, MX 500 500gb ssd, WD 1TB sata internal hdd, AHCI,windows10,
running UEFI and secure boot, MY SSD in GPT and NTFS but my HDD in MBR and NTFS, CSM is disabled.

i just clean installed my win10 on my new crucial mx500 500gb ssd and did not create any partition in it.
i was copy pasting total 55 movies with 80gb total size in mx500 sata ssd but it's giving only 150-250 MBps speed(most time <180MBps), is this normal? yeah i was copy pasting within same drive. at first the speed starts at 450-500MBps for few seconds then drops to 150-250 MBps.

below is in real world performance profile of CrystalDiskMark

is this good?
also i have connected both my HDD and SSD with single sata power cable from psu, is it ok?
Also does really using momentum cache in crucial storage executive software improves speed? I still haven't used it yet.

Run CrstalDiskMark...

As long as you are not running a 12 year old mainboard, most SATA3-capable boards/ports should allows ~500-560 MB/sec sequential reads... (if you see only 250 MB/sec, I'd investigate why it is running at SATA2 speeds, for instance)

That is acceptable.

 

[eziowar]

That is acceptable.

thank you for replying, though CrystalDiskMark giving acceptable results, but what do you think about - "i was copy pasting total 55 movies with 80gb total size in mx500 sata ssd but it's giving only 150-250 MBps speed(most time <180MBps), is this normal? yeah i was copy pasting within same drive. at first the speed starts at 450-500MBps for few seconds then drops to 150-250 MBps.

Copy/paste within the same drive WILL show slower speed.
It is doing both at the same time.

thank you and i spend all day in trying out different sata cable/port combination, bios settings, intel rapid storage, trim, write cching, indexing etc whetever i found on the net,
