Can some of you post your POST firmware crystal disk results for 80 gig G2

Would be nice to see the range of performance for that drive after the firmware update.

I think this is better program to test your SSD.

before update:

sequential read: 134 MB/s,

sequential write: 69 MB/s,

after update:

sequential read: 133.9 MB/s,

sequential write: 82.79 MB/s

random read 512KB: 115.6 MB/s

random write 512KB: 82.11 MB/s

random read 4KB: 18.75 MB/s

random write 4KB: 27.73 MB/s

looks like sequential write has improved, I think the random write too, but I don't actually remember the values before the update

Palerider are you sure your numbers are correct. You Seq read speed is pretty slow...

yeah I know, my seq. read is slow because my MB doesn't support SATA II, so that's the best I can get,

I plan to buy the SATA II PCI controller to fix this.. (note it's PCI, not PCI-express, so it might be hard to find..)

PCI bus bandwidth is 133MB/s, which is less than SATA I, so there would be no point in a PCI SATA-II controller.

actually the PCI bus bandwidth is 133MB/s with 33Mhz on a 32bit bus, but with 66Mhz on the same 32bit bus it is double (266 MB/s). If you have a 64bit bus it is even bigger (double again).

66Mhz was introduced with PCI 2.1, my MB has 32bit bus and it supports PCI 2.2 so I should be ok.

here are some facts about PCI 2.1, according to wiki:

PCI 2.1, released on June 1, 1995, allows for 66 MHz signaling at 3.3 volt signal voltage (peak transfer rate of 533MB/s), but at 33 MHz both 5 volt and 3.3 volt signal voltages are still allowed. It also added transaction latency limits to the specification.http://en.wikipedia.org/wiki/Conventional_PCI# cite_note-6

btw, I already found the controller and ordered

Palerider's sequential read results are correct, unfortunately. He/she is bus-limited with a 33 MHz bus. I have the same problem with my Intel D620 laptop with an old Dell-implemented ICH-7 southbridge. Time for a new machine one of these days....

This is a G2 80GB running 02HD.

4K's seem kind of low compared to the rest of the thread. This is installed as the primary in a Gateway P6860FX (http://support.gateway.com/s/Mobile/2008/GodzillaFX/1015340R/1015340Rsp2.shtml http://support.gateway.com/s/Mobile/2008/GodzillaFX/1015340R/1015340Rsp2.shtml) laptop running Win7 x64.

Any idea what's holding me back?

Thanks!

Thanks everybody. Looks like most of us are in the same general ballpark now. Just wish there was a definitive test to see if trim is working. Something visual like a graph or something. Here is mine after the trim update today.

You all need a good RAID card - &itches.

What raid card are you running?

RAID card is Areca 1280ML - 2 gig of RAM.

Smoothmole,

How many drives does that measure represent?

It's 11 drives - not SSD (1 TB ea WD RE3s).

Here is my SSD - not attached to the RAID card (because I won't get TRIM). Running off of an Asus P5Q Deluxe, default Windows Drivers.

Can anybody think of a reason why my crystal marks are low? especially the 4Kread.

Was the same before the update to 02HD

I'm using 80GB G2 drive in a Dell E6400. All drivers are correct per the many posts on this site
