Solution?

Problem: In Windows 7 "Safely remove hardware" works very slow.

I found out reading the forums that this might be because every time you click on the icon to remove an USB device, it loads the data about the devices in "Devices and Printers" which process is very slow. So if you have "Devices and Printers" open BEFORE you click on safely remove icon, the menu (what to remove) appears instantly. Sadly this is not a real solution to have this open all the time. I didn't find any fix to this, but there is a very good alternative if you want safely remove your devices in almost the same way - it's a programm called "HotSwap!" - definetly worth a try!

I switched from Keepass Password to S10 Password Vault. I didn't need/use all the features Keepass Password offered, and I wanted a less robust, much simpler freeware for storing my password. The only feature missing is the ability to search.

Quick power consumption test

Mon, 30 Mar 2009 18:31:00 +0200

Since my new system has an "energy efficient" processor (45W), I thought I would do some measurement (I used HQ's Power Meter). I measured power consumptions in near idle states of the systems. Here are the data:

System 1 - Fujistus Siemens Amilo-Si 1520 notebook (specs): ~30W
System 2 - My old desktop computer: ~130W
- ABIT KV7 motherboard
- AMD Athlon XP Barton 2800+ 333MHz processor
- XPertVision Radeon 9600Pro 128 MB video card
- Seagate 80GB 7200 rpm SATA HDD
System 3 - My new desktop computer: ~70W
- Gigabyte GA-MA78GM-S2H motherboard
- AMD Athlon X2 4850e processor
- Seagate 500GB 32MB SATA2

A little benchmarking

Wed, 25 Mar 2009 19:26:00 +0100

I installed my new desktop PC (Gigabyte GA-MA78GM-S2H motherboard, AMD Athlon X2 4850e processor, Kingmax 2GB DDR2 800 MHz) and since the motherboard has an eSATA connector I was able to use my WD My Book Home external drive via it's eSATA connection. I was playing a bit and did some benchmarking and tested actual file copying speed with some of my HDD's. I tested my:

Western Digital My Book Essential 250GB external HDD (USB2)
Western Digital My Book Home 1T external HDD (USB2 and eSATA)
Seagate 500GB 32MB SATA internal HDD
Samsung SP2504C 250GB 8MB SATA internal HDD.

First I run two hard disk drive benchmarking tools: the aged ATTO Disk Benchmark and HD Tune. Then I copied a 640MB file with Windows Explorer (native) and with TeraCopy free version (2.0 beta 4) and measured the time it took to copy. Then I did the same with 4 files altogether measuring 5,57GB. I gave copy speed in MB/s, actual time is in brackets. Here are the results:

Western Digital My Book Essential 250GB (USB2) [free space: 3%]

Copy test:

Western Digital My Book Home 1T (USB2) [free space: 76%]

Copy test:

Western Digital My Book Home 1T (eSATA) [free space: 76%]

Copy test:

Seagate 500GB (internal SATA) [free space: 95%]

Copy test:

Samsung 250GB (internal SATA) [free space: 6%]

Copy test:

Summary, conclusion?

It is very hard to draw any conclusion because there are so many factors affecting data transfer rate and because of the inaccuracy in measurement.

It seems that:

TeraCopy increases copy speed, especially when copying larger files; on my internal Seagate HDD it was 1.5-1.7x faster
WD My Book Home eSATA interface is approximately twice as fast as it's USB2 interface.
