I just bought a new SSD, and installed a fresh copy of Windows on it. I didn't see any noticeable difference in boot times, app start-up times, so I decided to benchmark it.

Asus P7P55D-E
Intel i5-760
Samsung 830 256GB SATA III
Windows 7 Ultimate 64-bit

The Windows experience index gave the drive a 7.3 rating, but real-world performance is not particularly impressive.

ATTO AS SSD Samsung SSD Magician

Any ideas why the numbers are so low?

UPDATE:

It turns out that SATA III support is turned off by default on the P7P55D motherboard. After enabling it in BIOS (Tools -> Level Up), the scores went up:

      Read  Write
Seq   325   183
4K    16    49
IOPS  32K   28K

It's an improvement, but still far below what they should be for this drive.

Recently I managed to completely mess up my ASUS 900, but I have no immediate desire to upgrade since it's only my travel laptop (and I'm waiting for a few months to see if anything interesting comes out). For now, though, I've hit an interesting problem. The 4GB SSD that is soldered onto the motherboard… >>> More
