hi...i had a choice to pick up either x32 or pay a difference and get p64 drive from corsair...now i took x32 without checking much online, but upon logging here i see there are some problems...did i make the right decision, or should i go exchange the drive

 

now all i care is pure performance...size is not important, i just dont want to get stuck with the drive that has less capability than advertised

 

i have to make decision today because they will let me exchange in one day...can you guys help me out?

 

which drive should be faster?

 

thanks :)

The performance of X-32 is 210 MB/s sequential read and 100 MB/s sequential write.

The performance of P-64 is 220 MB/s sequential read and 120 MB/s sequential write

So they are close to the same as for as performance. But in this case the P-Series will have slightly better read and write performance.

 

However, if you compare apples to Apples and the X-64 is 220 MB/s sequential read and 135 MB/s sequential write.

Which is slightly faster than P-Series.

I would suggest using Parted magic to wipe the drive (Under Tools Select Erase Disk) and then Select the drive from the list and select Secure erase then format the drive using the Quick format with 32K Allocation option and test the drive with ATTO Disk Bench

this is what im getting on vista 64 bit, phenom 2 940@3.5, 4gb of ram

 

rather dissapointing...it falls well short of declared speeds...do you guys have anyting i can try to raise the performance???

 

Keep in mind also that your score is going to be slightly lower when running the OS on it. So, if you are benching the drive while it is running your OS, that is likely the discrepency.

update...i have kept x32 drive and installed w7 64-bit on it, and so far it seems good...the writes seem to be 90-95mb and reads 200-210mb...this is only on ATTO...on crystal its 55mb write and 175mb read...same with some other ssd benchmark...does anyone know why is that...anyways im running os and wow client on it and all i can see is occasional small hiccups like 0.5-1sec...are those multithreaded write pauses?...do extreme series have them?...any insight would be appreciated

 

btw...i found the best performance by allocating 2k upon quickformat

how do i do that once i have the system on?

 

do i have to reformat then reinstall?

 

tnx

 

update:

another thing i noticed on vista is the crooked atto benchmark like it is above when using ahci...when using native IDE then i got normal results.-.

I would suggest using IDE mode unless you do the Install with that enabled.

And you would have to image the drive like with Accronis Disk Image to another drive then reformat with the Quick option then test the drive with ATTO as a second drive then if its working properly delete the partition and re-image the drive.

ok here is the problem in a nutshell:

i have pictures of every single step...the drive is not working as it should, after the last 5GB on it get used...take a look at this...amazing difference:

1. secure erased disk, formatted default 4096

2. added 16gb file, 14gb free

3. added another 5gb file, 10gb free

4. added another 5gb file, cca 5gb free

drive still going strong seems like

 

now, the total breakdown :(

 

5. added another 5gb file, cca 500mb free

:eek:

 

6. deleted that same one 5gb file, cca 5gb free

:confused:

 

the usage of that last 5gb just seems to have done the drive in :(

 

7. deleted another 5gb, cca 10gb free

you get the picture :S

 

8. quickformatted with 4096 setting, 30gb free

a disaster

 

unfortunately i have paid for 32gb usable SSD not 25gb so i will be returning this...i am interested can anyone with x32 verify that the drive after being charged all the way goes to this miserable performance?

or is the drive simply faulty ?

 

let me know

so are you saying it would eventualy come back to the old performance if i left the drive half empty?

 

also...this other drive i have now i have filled up all the way to 60gb, and it hasnt lost any performance, so its not happening to other drives like you said

 

thing is i have to run win7 and wow client on ssd, so it leaves only 2-3 gb of space on x32, and that "kills" it...i dont have a budget for a bigger extreme drive from corsair so i took other brand that support trim, although not automatically, but through wiper program...well see how that goes...

Yes if the drive firmware has Garbage collection or you are running Windows 7 with firmware support for Windows 7 TRIM.

 

And If you have a drive that does not slow down when its full then I would use it, but I have not see any drives not slow down as they fill up even a spinning HDD.
