sorry to resurrect but I am having (I think( similar performance trouble with same 2x Mushkin Chronos 240gb in raid0. a single drive can hit over 500MB/s in Sequential Read of AS SSD, but once raided they do not go above 395MB/s which is awkward knowing that most SSDs double that value while in raid0.
also, can anybody remembering those numbers from OP (AS SSD or CDM) post them? the pic in OP is gone and nobody ever wrote that in text ... this is so far the only thread I found mentioning those drives.
for future reference of later generations here are my benchmarks with AS SSD done on Maximus V Extreme using intel SATAIII/6G ports, BIOS 1707, OROM 11.0.1339 and IRST driver 11.7 under win8x64 (UEFI boot mode with secure boot):
a) either of single Chronos 240GB (non-deluxe) drives, either in AHCI or RAID controller mode
b) 2x chronos 240gb in raid0 (128KB strip, write-back cache enabled) - that's a pure sadness in performance category down there
in ATTO everything looks normal good (up to 1050MB/s or so), but that software uses uncompressed data fill, no? useless for real life comparisons ...
... why didn't I go with samsung pro ssds ...Edited by feniks - 3/31/13 at 11:03pm
