Show us your SSD performance

[Hopalong X]

I got snipper tool just had pic on camera. I was at work.
The only worry is that SSD's dont last that long.I better back some stuff up (game wise)

The rumors that SSDs don't last long were exaggerated.

SSD Write Endurance 25nm Vs 34nm


The SSds are being written to as fast as possible to get actual life expectancy data.

They are lasting a very long time, much longer than the manufactures stated amount of writes.

At these amounts, an SSD will last a average user 10-20 years or more.

The Crucial m4 wrote over 800TB before it quit working.
This is what Britta is using.
That should be a good system for them.

m4 became undetectable on multiple mother boards.
Cause of failure of the m4 was inconclusive.
Internal electronic part failure. As simple as a capacitor or resistor.
The controller could have failed.

NAND did not wear out from bad sectors/blocks etc.
RAS- 00 Reallocated sectors. None. :shock:

This was my last result update.
m4
768.5687 TiB
2749 hours
Avg speed 88.43 MiB/s.
AD gone from 171 to 169.
P/E 13330.
Value 01 (raw read error rate) has changed from 43 to 46.
MD5 OK.
Reallocated sectors : 00

The M4 passed MWI-1 at 170.8 TiB.

There were no problems before I turned my rig off the 28th oct. It just didn't like 9 days without power.

Received my OCZ Vertex 2 SATA II SSD today, did clean installation of windows. Downloaded and executed benchmark and here is the result

something doesn't seem right, the result is quite low compared to what says on the box - Read 285 MB/s Write 275MB/s

I hate to be the bearer of bad news, but.. You are in IDE mode. You need to be in AHCI mode. This tutorial on how to change to AHCI will show you how to do it.

Essenbe beat me to it, but he is correct.

You can enable ACHI after installation:

Ooops, I see he has edited his post and added the tute

 

[carwiz]

Never mind. I was watching a movie.

Everybody beat me to it.

The guys are right - you will get better nums in AHCI mode. That, however, may not translate into a big difference in real (OS) life. Just to warn you in case your performance does not change significantly and you wonder why. Reason is because the access time is not going to change.

 

[carwiz]

I'm pretty sure it will increase significantly. The access time shown is a measurement of how long it takes to address the first block. After that, sequential transfers are measured in nano-seconds. The OS makes frequent use of sequential reads and writes, especially when loading programs or paging memory. The limitation will fall on SATAII.

The theory is right. But in practice we are talking about very little data that the OS manipulates at each time - and that mostly in 4K blocks. So the real impact of a slow data transfer speed should be minimal.

So the real impact of a slow data transfer speed should be minimal.

If that were the case, there would be no reason to use a SSD. Are you saying we should all go back to IDE drives because there's no benefit to SATA? Sorry, but I disagree.

I agree there is a benefit when using AHCI or RAID (same benefit for both, they are basically the same).

The red font letters "pciide - BAD" indicates you are in IDE mode, as already mentioned.

The "BAD" indicates your SSD is not correctly aligned, this will cause poor performance.

The best way to ensure proper alignment is to point the Windows 7 installer to a unformatted SSD, it will align and format the drive for you.
Cloning or using a backup from a HDD will not have the right alignment.

Here is a good tutorial that will help you with alignment.

After changing to ACHI mode in BIOS and registery file, here is new improved result

Better numbers now, as per alignment tutorial, I don't need alignment doing cause I did clean install of windows 7. My wei score also boosted from 5.9 to 7.7

No, I am not saying that. What I say is the the performance kick of the SSD comes from the ultra short access time and that the data transfer speed has only a minor role to play (when the SSD is used for the OS).

That will be different once we have large affordable SSDs where we move a lot of data around - e.g. use them to store images. In that case, the data trnsfer speed will become more significant for the overall performance. But the OS does not R/W a lot of data at any given point in time.

Of my 5 SSDs 2 run in AHCI and 3 run in IDE and I really see no difference. When you measure them, the differences show up, but in the daily operation it does not.

That's more like it, well done.

Enjoy the speed

Hi SevenForums,

I'm a new convert to SSD technology. Its only a Samsung 470 series 64 gig I have installed for my laptop. I use it as a boot disk for O.S and my music D.A.W and Pro DJ software.

My laptop is optimized for music production, so we are talking no web access at all totally stripped down Win 7 home premium 64 bit so it can produce and play real time music professionally in and out the studio.

Before the SSD upgrade the system was quick as it has so many features disabled and tweaked out to transform a business - mid level multimedia machine into a fully fledged real time dj/producers machine.

Even then it took about 30 seconds to fire up. The laptop was quick and I enjoyed Win 7.

I would press the on button.... machine fires up.. then into my music D.A.W which are Cubase and Sony Soundforge pro 10.

Now she fires up in about 7 seconds from cold.

But the most important thing is the way the music D.A.W loads and reacts with serious amounts of virtual outboard and soft synths. These are all programs.. within programs if you catch my drift and they all respond very well to the SSD.

I use external USB drives for my samples as I did not want them on the machine, as I have about 700 gb of WAV and they all fire up when needed quickly within the projects lovely.

I use Native Instruments Traktor Pro 2 DJ software to perform out, this has transformed the software a lot, as it uses stripes and other data that is saved on the SSD when Traktor analyses the data for example when you add a track to your collection or playlist. The software reacts very quickly when loading 24 bit WAV music files as the core data is scanned in and just the music file is external on my various USB drives. Less than 1 second.

This is all fantastic, you can see why so much has been said about the bottleneck effect conventional 2.5 mechanical drives can have on a laptop system. The Samsung drive I have is a very modest SSD and my machine reacts in such a fantastic way its really is profound and Win 7 really is lovely experience to use.

Have a great week all.

Glad you like it, enjoy.

Just got my SSDs hooked up. I never expected results like this

 

[whs]

Amazing indeed. I think this is the highest transfer rate I have ever seen.

 

[rev0]

Really?? I'm glad I decided to go with OCZ then.

I was getting 200-300 mbps but after I updated my storage controller the transfer rate sky rocketed.
Im kinda interested to see if a true hardware card could squeeze some more out of it. . . Tempted to pull my RAID 5 array out for a few mins and hook these up.

Yikes! :shock: Those are great numbers. Be careful or you will go back in time. A Guy
