I bought a netbook, Windows Starter - it seemed really slow right from the start, so I removed all the bloatware, but it remained slow still. So I tested disk I/O with CrystalDiskMark and got
4k read: 0.296 MB/s
4k write: 0.842 MB/s
Seq read/write was allright, with 50 megs per sec. Disk in question is Seagate ST320LM000 HM321HI.
How to fix this? Thanks

You have a 5400RPM drive with 8mb cache -- pretty low-end, to put it nicely -- and which is also known for early failures. Look at the specs on the HN-M320MBB drive, which is the original model for this now-Seagate-labelled drive, though you should be getting much better. Make sure you don't still have something like antivirus software slowing things down. The drive specs are at http://www.samsung.com/global/system/business/hdd/prdmodel/2011/6/9/156582m8.pdf :
Average Seek time (typical) 12 ms Linear Shock (1/2 sine pulse) Average Latency 5.6 ms Operating, 2ms 325 G Data Transfer Rate Non-operating, 2ms 750 G Media to/from Buffer (Max.) 145 Mbits/s Vibration (swept sine, 1/4 octave per minute) Buffer to/from Host (Max.) 300 MB/s Operating 1 .5 Grms Drive Ready Time (typical)3 4 sec

Fix what exactly? What is your question? – None – 2013-10-09T18:46:15.353
I presume that the fact the disk is reading/writing random data under 1MBps is causing the slow performance? If that is so, what to do to improve 4k read/write. – srgb – 2013-10-09T18:49:15.703
You bought a netbook running Windows Starter edition. What specification is the netbook? By definition, they are slow machines, running a minimal setup of Windows due to resource constraints. I think your question is asked and answered by this fact. – None – 2013-10-09T18:51:35.877
Mate, no hard disk should have a 200kB 4k r/w speed. – srgb – 2013-10-09T19:06:24.987
Then your hard drive is faulty, no? – None – 2013-10-09T20:07:14.287
