I did a little optimization and managed to get 281 MB/sec max read speed with ATTO. Write maxes at 215 MB/sec as you can see in the pic.
The read speed is close to the 300 MB/sec SATA 2 maximum, so I can't complain much.
My optimizations included:
-disable readyboot (not readyboost, that was already disabled for me)
-disable thumbnail cache (probably didn't much matter for the bench)
-changed to AHCI, instead of a RAID config in the Windows 7 registry and in my bios
The last one seems important because this drive does not support RAID. Even though the drive wasn't configured as such, totally disabling it did seem to boost performance. Readyboot I noticed was using the disk a lot also.
One last note. Even though the drive does spec out as max read and write of 450MB/sec, the random 4kb read/write has a major advantage towards read. Newegg shows a 40% increase in read speeds at random 4kb. Also the bar graph shows an advantage towards long sequential operations, so an averaged benchmark would be misleading.
And be sure to try another SATA cable before returning.
Your attachments aren't working for me. Did you click the little paperclip?
With regards to SATA 2, the maximum you can expect is 300MB/sec. Though given our apparently crap 506 firmware even that seems far off, at least consistently. Obviously the Samsung 840 Pro would be best and would be guaranteed to max our SATA 2 (blast to the past...lol), but I don't think it worth the cost.
I guess the reality is they might not ever release a 507 firmware and there is no way to downgrade. Worse still is some suggest that it isn't the firmware but the manufacturing that can be either Taiwan or China. China having the possible bad drives.
if attachments still dont work, my ATTO results are quite similar to urs. The last bar of 8192 in atto for mine is 229mb write 272 read.
Ultrabook, 4GB soldered RAM, 20GB SSD cache. Sata II.
With the stock 2.5" HDD, CrystalDiskMark (64 bit) showed 62/63 MB/s sequential read/write, respectively. Same test, same way, after the SSD install was 173/107 sequential read/write, resp. I run CDM as it loads (I don't change any parameters because I'm not smart enough to know what to change).
Should I be expecting speeds closer to 300 MB/s or are those numbers in the ballpark?
