Vertex 2e WEI drop from 7.7 to 5.9...

Hi All,

Until recently my WEI was giving me a 7.7 for my vertex 2 in ACHI format.... The other night I re-ran the WEI and now everything is the same for other system components but Hard dirsk is reading 5.9! Do you have any idea why this might be happening? Also, I compared my A5 SSD read write scores with the Vertex 3 scores posted in another thread on this forum... hmm.... My read speed are fine, around 220mbs on a sata 6, but my writes are crap!!! 50mbs -

Has my drive become damaged perhaps? :confused:

anybody can you help?

Let the PC idle so TRIM has time to perform, when benchmarking your Vertex 2 SSD use ATTO diskbenchmark

Don't the Vertex 2 drives permanently go to a slower write speed once all the cells have been written to once? Might explain the slower write speeds you're getting.

The benchmarking itself will QUICKLY degrade your reads and writes.

1: Ignore WEI. It is worse than worthless.

2: As noted above, let TRIM catch up for a few days. If your speed does not return, secure erase your SSD and restore from an image or reinstall the OS.

3: Stop benchmarking the drive. This will accelerate your wear and tear and slow the performance.

What image software do you use? I've not been able to find a good one.

Use the built in image creation tool on Windows 7 or Macrium reflect which is free.

Thanks fantastic people!

Can always double check bios that its in AHCI mode still, my Crosshair mobo has a habit of, any time it crashes it both tends to turn off the core unlocker(ruddy irritating) and now and then it also reverts to some other "stock" settings like IDE over AHCI.

Its more noticeable on some drives though, my C300 is horrible on IDE or if its misaligned, while on AHCI is freaking awesome.

Those are worth checking, but in general use as others have said, as long as windows "feels" ssd smooth then its almost certainly working fine, and its best not to benchmark the drive as , well it doesn't really hurt performance long term, or shouldn't but a "used" drive can give you results that look dodgey.

The windows image tool(in win 7 anyway) is pretty nice, make image on another drive, secure erase the ssd then reinstall using the image.

Infact I'm fairly sure you'd end up with a "cleaner" install of windows that way. With a normal install its unpacking and repacking drivers all over the place, writing and rewriting to blocks all over while theoretically from an IMAGE it will be one continuous write on as few cells as possible of which a lot will never need to be re-writen, also leaving the rest of your drive as clean as possible.
