Unhappy 20-25MB/s read on Apple SSD

My Dad's got a mid 2009 MacBook Air (2.13GHz) and has a 128GB Apple SSD inside. I thought it was a bit slow loading up for a computer with an SSD, so checked the read and write speeds, turns out it's reading at about 20-25MB/s, but writing at around 100MB/s.

I'm not sure what I can do to make it any faster, would anyone have any ideas?

Have you run a verification on the SSD using Disk Utility?

Those PATA SSDs were fairly slow to start with, if it's 3 years old, it may be on its last legs.

Oh really? Do you know if you can replace them at all?

You should be able to, OWC offer these drives, which should fit the 2008/2009 models.

I'd expect writes to slow down significantly long before reads.

Fair point, reads shouldn't be that low either way though.

I only know that reading at 25 MB/sec is not normal. Reads on an SSD drive should not slow down. I'd make sure that anything important is backed up. You should do that anyway, but I wouldn't trust the drive.

Always good advice.

SSDs are new enough that their failure behaviors are still kinda novel and unfamiliar. And 128GB SSDs are cheap enough that you can buy one, swap it out, and know that that won't be a problem anymore.
