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_!
