Alright I am having some trouble with one of my hard drives. The computer it is in is just a storage computer really it has 4 drives in it. 1 500gb system drive and 3 1.5tb storage drives. I didnt notice when it started but today I was transferring some files around and noticed a problem.
Drives 2 - 4 are my 1.5tbs
When transferrings from Drive 2 to Drive 3 my average speed was around 60-80MB/s which is normal some when transferring files from Drive 2 to Drive 4 or Drive 3 to Drive 4 and vice versa.
I start running into troubles when Drive 3 or 4 starts to transfer to Drive 2. Instead of the 60-80mb/s I am now getting 5-8mb/s.
What would cause this drive to write so slowly but not alter its ability to transfer to other drives? Could the drive be failing or maybe cable problems?
I ran HDTune on all 3 of the 1.5tb drives and they all benchmarked very similar. They are all defrag'd every week and I ran the error-checking thing from windows and it came up with nothing.
The drive speed will slow down quite a lot if there is activity from other programs going on at the same time on that drive, or if you are transferring a lot of little files (as opposed to a few large files).
It may be the case that some of your drives are sitting on a different controller. Usually 4 SATA ports on the motherboard will be handled by the onboard Intel controller and another 2 SATA will be handled by a 3rd party (usually Highpoint). Hence if the Highpoint drivers for example where not installed properly, or were corrupted, you would experience weird performance results.
Ah ok that make sense. On this computers setup it actually only has 4 ports on it because its a small micro atx board. I did switch ports though and the hard drive is still acting the same I also switch out the cable which didnt help either.
I am thinking it has to be the drive at this point I dont have much else to check..
