My Western Digital WDC 250gb SATA 150 8MB cache hard drive. The problem I have is that my harddrive is only getting 54mb/s of throughput benchmarks. Any way I can improve my harddrive performance.
Hi, Your transfer speed is as good as ou're going to get on that drive. Bench tests show it having a transfer speed of 58mb/s so having 54mb/s is almost spot on. Other than keeping the drive cleaned and defragged with a good program such as o&o defrag or diskeeper your not going to get much more out of it. You are never going to get 150/300 mb/s as this is the interface bus speed not the actual capability of the drive. If your expecting that, then you're another person thats just been taken in by the sales hype.
No I was never one of those that fell for the sale hype because I know that all maximum throughput that is labeled for computer components is just theoretical. But if you look at SISsoftware benchmark software, my harddrive performance is way below normal. I never expected to get more 150 or even 125mb/s but even PATA drives are outperforming my drive. Any else can assist me in atleast getting my drive up to 80mb/s or more?
You are never going to get it up to 80MBs, the 150/300 speed of SATA is not theoretical, it is the speed of the SATA interface. The actual drives are the bit that are slower, if you have 4 drives working on the same controller, then that is where is start to get up to the speed you are looking at. If you read this here, you see that even the Raptors with the 10KRPM spindle speed, only has a sequential write speed of 68 MB's, the Seagate Barracuda ST380013AS which is close to your drive, only has a speed of 56MB's (bth of which were recorded using SiSandra. http://www.pcstats.com/articleview.cfm?articleid=1746&page=3 If you do manage to get 80MB's out of that drive I'd be pleased to see how you do it, so would the rest of the many SATA drive users no doubt.
Ok then let me ask some of you guys on this board. Those that have a singlle SATA harddrive, what type of throughput are you getting?
65.1 on my 74GB Raptor 48.8 on my 250GB (stuffed full) Maxtor http://www.simplisoftware.com/Public/index.php?request=HdTach this is a good program for judging and comparing hard drives. Sandra is still about the best program, but this is a little more HD specific.
The SiSandra speed of my C:\ drive is 106MB's (2xRaptors in RAID0) Will run a defrag later and test again.
