not sure
Hi all I have just got me a 250GB Samsung 850 EVO.

I did a test in HD tune 5.00 and I am getting terrible speeds

Reads are about

minimum 156.4 MB/s
Maximum 163 MB/s

This is slow

PC specs are

win 10 64bit
Asus p7p55d-e
R9 280X vapour X
16GB ram
the SDD above
a 500GB mechanical drive
and a DVD drive

please advise I have AHCI enabled in Bios etc
 
did you change HD tune from 64k to 8mb before running the speed test? as leaving it on 64k will give you "slow" speeds.

its under options and benchmark if my memory serves me right lol
 
I googled your mobo and you have plenty of Sata3 ports. I'd just make sure you're using the Intel ones rather than marvell.

Also, you could try installing Samsung Magician. That may tell you if something isn't configured properly. I have the same drive as you:

ok installed samsung software

I get SEQ reads 284
SEQ writes 272

this aint to bad

It also says I am pluged into a none sata 6 port whice I know I am so will loose speed doing this

I have a jmicron 6gbps sata port on the mother board but I just connected the SSD to it and it boots to windows icon then says it failed as it cant find OS or some thing.

Suppose i could reformat with it in the corret sata port to start with?


also do I need a sata 6 cable or can i use any sata cable?

thanks
 
nope its in the blue at the moment

the sata 6gbps port is grey/black but it started to boot but then got the the windows spinny thing and said it cant start windows or some thing

probably need to reformat etc with it in the 6gbps port ?
 
hi I did that and it did start to boot thats the thing then i got a unhappy face with an error.

I might reformat again but with it all ready in the 6gb/s port?

seeing as sata cables are all the same I might as well give it a go?
may as well try to get max performance from this drive dont you agree or should I just stay with the 280mb/s etc

Jmicron are a crap controller any way aint they tbh?
 
Nowhere near 400MB/s... :D

If it's any consolation, GTA V doesn't appear to load much faster than it did from my mechanical hard drive. :( It just goes to show what a crock of **** these benchmarks are. :p

LOL you sod :P

Oh I realy should slap this thing in a 6GB/s port.

I shall play a few games and see if I am happy with what I get now tbh I am sure I will be but ya know us humans are always after some thing for nothing etc :P

EDIT

Really hmmm wonder why that is though?

Any who af5er testing a few games its faster than me old drive so im happy.

Best of all when me pc gets older i can always slap it in the 6GB/s posrt for an instant overclock LOL
 
UPDATE

Well I did it I put the SSD on GB/s and get these speed

Its still no where near the 500MB/s mark
is there a fault or could it be the crappy sata controller :(

it is a little faster in read than the old port but i have lost writ speeds etc this just dont seem correct?
 
its because your sata 6 ports are using a Marvell controller.

from the mobo website

Marvell® SATA 6Gb/s controller:
- 2 x SATA 6.0 Gb/s ports (gray)

I have a x 58 board using the same controller and I cannot get the full speeds. max I can get is 400mb read and 250mb write.

the Marvell controller is crap and cannot reach full speeds for any SSD

I didn't know this till I got my SSD so it sits in the sata 3 ports and get 280mb read and write as its a intel controller, still good to get a ssd :)

Yeah tbh i was leaning towards it being a crap controller.
ah well I stuck it back into the 3gb/s port and get about 300mb read and write so its better than the crappy "6GB/s" LOL.

thanks and will just leave it till I get a new computer (not likely way to much money)
of if it really gets to me get a dedicated controller? would this be a good optoin any recommendation?

Thanks all
