Asus Eee PC 1000HE WinSat Disk SSD performance

Since we have been on the topic of WinSat performance in the various configurations we have had here in the shop with Intel’s new second generation solid-state drives, we did not test the Netbook that started the whole thing off!

So, here are the results:

The specific Asus Eee PC 1000HE SSD performance variables we look at:

• Disk  Sequential 64.0 Read                133.19 MB/s          7.0
• Disk  Random 16.0 Read                    122.65 MB/s          7.3
• Disk  Sequential 64.0 Write                73.57 MB/s          6.1
• Total Run Time 00:01:31.76

This was the Toshiba Tecra S10’s 160GB Intel SSD’s Winsat performance (previous blog post) the last time we measured it.

Here are the Tecra S10’s single 160GB SSD read/write stats that we retook today:

• Disk  Sequential 64.0 Read              215.06 MB/s        7.4
• Disk  Random 16.0 Read                    63.50 MB/s        6.7
• Disk  Sequential 64.0 Write              87.69 MB/s          6.3
• Total Run Time 00:01:28.20

It looks as though the I/O bottleneck has been dealt a serious blow on both configurations. Though, the S10’s Random Read number does look a little low relative to the Netbook.

The Netbook is running Windows 7 Professional x86 (32bit) with no BitLocker Drive Encryption while the Tecra S10 is running Windows 7 Enterprise x64 (64bit) with BitLocker Drive Encryption enabled.

All in all, bumping out the 160GB 5400RPM SATA drive in the Netbook was a _really good decision_!
