First IOXTREME Review

[alfaunits]

Did you try to format using the Maximum Write Performance setting? What does it actually do in terms of capacity?
If you did try it, did you try getting the IoXtreme in "surely used" state? (that is, writing several times its REAL capacity over, otherwise, the used state comes at a time when there is still free flash area).

[Spoiler]

Another test I would be very curious to see would be the performance differences between the X58 and P55 chipsets. Now that the PCIe clock is on the CPU for the P55, I heard the latencies are lower.

From this...I wonder if this would have any difference in terms of performance at least synthetic benchmark wise? The only problem with the P55 chipset would be the limited available lanes (16).

This does not exist on the ioXtreme. You can only choose to do this w/ the SLC versions of the Fusion-io's.

TH was able to make a format with different size on IoXtreme as well.

Maybe they just used Fio-format to specify a smaller size instead (i.e. there's no predefined setting).

Anyway, I found on FusionIo forum. The Improved Write Performance capacity is 50% of the max. and Maximum Write Performane is 25% of the max.! (i.e. if you format a 80GB IoDrive/IoXtreme for Improved Write Performance it will only provide 40GB usable space!)

Problem is TRIM isn´t mature.
TRIM with Indilinx-SSDs works fine (only with Beta-FWs)

They did that w/ the ioXtreme Pro, not the ioXtreme.
