|

Looking at this, it reports ATA5 instead of ATA6.
is this normal?
mobo
transfer speed between SSD>HDD:
about 500MB/s for ~1-2sec, then falls down to ~80MB/s

if you are using sata don't pay much attention what HD Tune says about UDMA Mode. afaik it's irrevelant for sata. I have 2 SSDs that both say UDMA5 active but speeds are as they should be.

get something like AS SSD and run a test.

i repeat again. UDMA 5 or 6 doesn't matter for SATA.

your read speed seems fine but write is slow. maybe drive is almost full?
and why does it say "SCSI disc", do you have your SSD connected to a 3rd party sata controller, like Marvell? connect it to motherboard native sata port for best speeds.

ok i noticed your first screenshot again and your drive is 90% full. your write speed suffers because your SSD is almost full.

so connection is ok?
RAPID is not enabled, because I'm afraid of data corruption in case of power failure (which happens)

Writes are very slow for that drive, but as said, it's rather full. SATA port 1 is the recommended port for an SSD drive on the Z87 chipset also, tells you that in the manual.

Different chipset, atleast on mine. Z77 OC Formula.
Some are Marvell, some are Intel, Intel is recommended for max performance.

But those 4k speeds are common for pretty much every HDD.
