Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

I'm not into gaming, but that's the same thing what bothers me - on which win os scsi performs the best...
with windows xp [sp 1] on my system seagate cheetah 15.3k has read burst speed 33.7 megabytes per second [measured with HD Tach] - I remember that someone posted here better results for this hdd.

Poor SCSI performance when using WinXP, or Win2k with SP3 or later @ SR FAQ
(see source for embedded links)
"To cut a long story short, in WinXP MS corrected a bug in Win2k that caused requests to bypass write caching to be ignored. This bug could have caused possible data loss (if the data hadn't been written to the drive and the power went out for example).
Unfortunately the correction of this bug also affects Windows Explorer. In many circumstances, when using SCSI drives, file copies aren't cached, and performance is extremely slow when compared to pre SP3 Win2k. Win2k SP3 and SP4 also have the XP 'problem'.
There is a Microsoft article that goes in to some depth here (cache).
There are a number of 'solutions' depending on your situation.
For Windows 2000, MS released a two part solution. First, a patch is installed to provide what is essentially a 'ignore bypass write caching requests' function. (Note: this patch is included in Win2k SP4). A tool called 'dskcache' is then used to switch on this option on a per-disk level. More on this available here (cache).
For Windows XP, it is rumoured that MS will provide a solution in SP2. Until then, there is a possible solution created by cas, an SR forum member. It is a program called xpcachefilter, which, when installed, filters out the bypass write cache requests on ALL drives. Note that as IDE drives don't support the command to begin with, it has no effect on them. More on this here (cache). It can be downloaded here (cache). Use it at your own risk.
For Windows 2003 Server, under Device Manager->*select drive*->Right click->Properties->Policies tab there is a setting to "enable write caching on the disk", and a further option to "Enable advanced performance". This last option reverts to the behaviour of ignoring bypass write caching requests.
For now, Windows 2003 Server or Windows 2000 SP2 is the best option for SCSI drive users who feel that they need the lost write performance back. Remember though, it only affects applications and benchmarks that request bypassing of the write cache. As mentioned above, this includes the Windows file copy function from Explorer"
generally speaking W2K is a much more mature SCSI platform
dont have much W2K3 info, but that wont be a "gaming" solution anyway
