238 MB/ SEC reads are not what I expected. I expected about 600 MB/ SEC. Write speed is mediocre. I've got the latest Win64 drivers from Adaptec installed. 5405 firmware is V5.2-0 16507. I have read and write-back cache enabled, I have a battery-backup for the Adaptec 5405. This is not worth all the money this setup cost me. The drives are new, they cost about $800 total and the controller was $225 on eBay.
Read performance looks great, due to cache. Write performance is awful.
WHERE'S THE BLISTERING SPEED THAT INTEL PROMISES?
If I'm doing something wrong, someone please let me know.
