Be sure to read our latest SSD article: The SSD Relapse for an updated look at the SSD market.

The Prelude

I spent about three weeks working on my review of Intel’s X25-M SSD. Most of that was research and writing and re-writing to not only review the product but also to talk about the rest of the SSDs in the marketplace and their deficiencies. Truth be told, I spent more time working on SSDs that weren’t the X25-M than the Intel drive itself. The Intel drive just worked as it should, the rest of them didn’t.

If you read the article, you know I was pretty harsh on some of the SSDs out at the time and if you’ve ever used any of those SSDs, you know why. Needless to say, there was some definite fallout from that review. I’m used to negative manufacturer response after a GPU review, but I’m always a bit surprised when it happens in any other segment.

I took a day or two off after that review went live, I think it was a day. Afterwards, I immediately started working on a follow-up. There was a strange phenomenon a few people noticed, something I unfortunately picked up on after the review went live; if you filled the X25-M up and re-benchmarked it, it got slower. And I had no idea why.

A few weeks later, I had it figured out. But then Nehalem was right around the corner. I’d tackle it after that. But then a new batch of SSDs from OCZ and other vendors were almost ready. I told myself I’d do them all at the same time. Then CES happened.

The More Things Change, The More They Stay The Same

If you look at the SSD market today, you’d assume that it’s very different from what it was just six months ago when the X25-M launched. People are worried that the Intel drive has issues with degrading performance over time. Some vendors are now shipping “revised” JMicron drives with multiple controllers, supposedly fixing all of the problems I talked about last year.

I hate to break it to you guys. As different as the world may seem today, it’s all very much the same.

The Intel drive is still the best of the best. Yes, it, and other SSDs do get slower over time and later in this article I’ll explain why it happens and why it’s not as big of a deal as you’d think. The issues I complained about with the JMicron drives from last year are still alive and well today; they’re just somewhat occluded.

Delay after delay kept me from writing this article, but I believe it’s for the best. What went in to what you’re about to read is nearly six months of research, testing and plain old work with SSDs.

The timing couldn’t be more perfect. We’re about to see a new wave of SSDs hit the market and it’s time to separate the fact from the fiction, the benchmarks from reality and the men from the boys. The last time I wrote an article about SSDs I ruffled quite a few feathers. That’s never my aim, but we’ll see what comes of this one.

    I need to run HDDErase on an X25-M. No matter what bootable CD or flash drive I create, HDDErase does not see either of my SATA hard drives. I already disabled AHCI in BIOS. Also, I am using version 3.3. I know that 4.0 does not work with the X25-M.

    Can someone help me troubleshoot this please? Thanks.

    You point out that TRIM will only work on deletions, not on overwrites. But, couldn't a smart controller look at blocks that have a majority of invalid pages and "trim" them as well, recovering clean pages as a background process? Reply

    Why not just make the SSDs capable of individual page erases instead of blocks? Problem solved. Reply
