Final Words

At the high level, SSDs are still the key to truly solid performance and this is where the issues with the JMicron based MLC drives are really unfortunate, because it means that the most accessible SSDs on the market can actually deliver a pretty bad user experience. But if you look at what Intel's X25-M and the Samsung SLC drives can deliver, it's really quite good.

As I've mentioned before, the random write issues with JMicron JMF602 based MLC SSDs are simply unacceptable and in my opinion they make the drives unusable for use in any desktop or notebook that you actually care about. Next year we may see a JMicron controller that fixes the problem but until then, I'd consider those drives off limits.

This thing is fast, and I want one in my system...actually, two. It's the only SSD that I would actually go out, buy and stick in my desktop machine at this point. I think that's the first time I've ever said something like that in a review, but I'm absolutely convinced. I've been using SSDs in my systems for a few months now and I'm hooked.

What Intel did with the X25-M is show the world what is possible with MLC flash. You get better than SLC performance, at lower than SLC prices. Despite that, the absolute only thing that bothers me about Intel's X25-M is the price. Although Intel is totally justified in pricing the X25-M at $595, I was hoping for pricing inline with the JMicron based MLC SSDs. At $300 - $400 this would be a no brainer for any enthusiast, and honestly even at $595 it's worth considering if you have other drives for data storage.

The other complaint is obviously capacity; at 80GB you can get by with this being the only drive in a corporate notebook or even your personal notebook if you've got external storage, but in a desktop machine 80GB is a bit shallow. Thankfully with better reliability than conventional hard disks you should be able to put two of these in RAID 0, doubling capacity without any fear of reduced reliability. Then we get back to the pricing problem unfortunately.

If Intel can get capacities over 100GB at reasonable prices in the near future, I'd say that the X25-M would be the best upgrade you could possibly do to your system. I'm curious to see what pricing and availability will be like for the 160GB drives, but Intel is being pretty tight lipped about them.

The implications of the X25-M are tremendous. I mentioned before that it is the great equalizer between the notebook and desktop, you can finally have a desktop usage experience on your notebook if you've got one of these in there (or a SLC SSD). If capacities grow quickly enough, these SSDs could mean that desktops would start accepting 2.5" drives, allowing for smaller form factors. Apple is already doing this on the Mac mini, and we've seen 2.5" drives used in systems like the ASUS Eee Box, but now you don't have to give up performance.

Intel didn't start the SSD revolution but it sure did kick it into high gear. Companies like Samsung and JMicron are really going to have to step up their game if they want to compete with Intel going forward. While Intel was light on details about the tricks they implemented in their controller, it's clearly enough to completely change the way we look at MLC SSD performance. And if this is the sort of performance we can expect out of its MLC drive, I'm wondering what will happen when we look at its SLC drives.

To me this is bigger than Nehalem, but then I look at the price tag and think that Nehalem will probably be a cheaper upgrade. Intel redefined the performance of the MLC SSD, I only wish they also redefined the price...

    Wow.

    #1 Meaning; Great read.
    #2 Meaning; Why do you not use World of Warcraft in your testings more? This game still has huge system requirements on absolute full settings in crouded areas. No one is getting 60fps in that game in Shatt on a saterday night 16xAA/AF full distance view. Everything maxed running a high resolution. Also, the disk access of this game may not be as much as Crysis, but its far FAR more prolonged as people play this game for a matter of years, instead of a handfull of months tops.

    What?! Google Chrome Launch Time? Is this a new benchmark? The world was waiting for that test I can tell ya! Did Google slip a little something in your pocket? Reply

    Sorry if this repeats what anyone else has said, but I think this is the best harddisk review I have seen. All the other hdd reviews I have read though, all go into detail about how many mb/s the drive can transfer and what the access time is, I/O performance etc. This is all very nice, but all we really care about is how does the hdd perform in real world apps and games in comparision to other drives. How much faster is my browser going to load.

    And that is why I was so impressed with this review. I realise it probably took more time to create this review, but it was well worth it. You can see how much the drives in the comparision compare to the amount of money you will spend instead of having to extrapolate from throughput benchmarks.

    I would feel a lot more confident in putting down money on the X25 after this review. Because I can see what the benefit I would get after in comparsion to other drives. Though the X25 needs to be another $100 dollars cheaper...

    Anyway, please more hdd reviews like this...

    Anand, could you please post map load times for R6 Vegas 2 using
    these drives?
    That game was killing me, and I'd like to know just how much
    happiness is around the corner :)

    I am very familiar with the tech works of SSDs and it is interesting to know of the security risk that involves the technology. http://www.techworld.com/SECURITY/NEWS/index.cfm?n...">http://www.techworld.com/SECURITY/NEWS/...cfm?news...
    This is one reason why I am not going to upgrade to SSD just yet till they figure out a more secure encryption.

    RE: PLEASE LEARN HOW TO USE COMMAS! by ggordonliddy, 19 hours ago

    You are just making it clear that you do not have a firm grasp of English. You are afraid of those who criticize poor grammar, because you know that you yourself will be exposed for the fraudulent pustule that lies beneath your slimy veneer.

    I have a life. I'm just sick of illiterate authors. Just because it is a tech site is no excuse for extremely poor writing skills. I'm talking about skills that should be completely mastered before being allowed to graduate from elementary school.

    ^
    Take your elitism elsewhere. If you actually practiced what you preached then you'd note your own comma abuse:

    "You are afraid of those who criticize poor grammar, because you know that you yourself will be exposed for the fraudulent pustule that lies beneath your slimy veneer."

    The second clause is dependent. Therefore, it does not necessitate a comma.

    "Do keep in mind though, the numbers we're talking about here are ridiculously low - even 900 µs to write to MLC flash is much faster than writing to a mechanical hard disk."
    But when it comes to random writes ssd's in general - this intel ssd included - fails miserably.

    Yes as the other poster say, the Intel drive have solved the issues with small random writes that the OZC and other MLC drives so far have been suffering from. If you read the whole article thoroughly you will see that clearly.

    Lets hope OCZ can come up with a better controller in their next generation MLC SSDs. We really need the competition here to bring those prices down, the Intel drive is a tad too expensive atm imo.

    Random writes are exactly as fast as sequential writes on this Intel SSD (10,000 random 4k writes per second).

    The article you referenced uses data from an SSD which appears to suffer from issues relating to the JMicron controller.

    The Intel SSD is obviously not affected, this is clearly shown by the numbers in this very review!
