Intel X25-M SSD: Intel Delivers One of the World's Fastest Drives

The Generic SSD
Intel isn't the first manufacturer to get into the SSD market, in fact quite a few of the companies we regularly deal with have SSDs. OCZ Technology, SuperTalent, Patriot, G.Skill, Mtron, and Silicon Power are just the names that contributed hardware for this review, but many more actually make SSDs.
Silicon Power drives provided by DV Nation
You'll notice that most of these companies are memory companies, not chip companies. Cracking open any of their SSDs reveals the true nature of their SSD manufacturing business: most of them simply rebrand someone else's SSD.
Let's take the MLC drives for example, here we have MLC drives from OCZ (the infamous Core), SuperTalent and Silicon Power:
Every last one of the drives has the exact same layout, same flash devices and same Jmicron controller (the JMF602).
The same is true for SLC designs, here we have SLC SSDs from G.Skill and OCZ:
They are the same, you could give them ice crea...nevermind
Note that these are the same drive, in this case purchased from Samsung and placed in new housing.
Only Mtron offers a slight amount of innovation by using its own FPGA as a controller:
But we know very little about any of these controllers so it's tough to say if Mtron's FPGA is done well.
For the most part however, all existing MLC drives on the market are built out of the same parts, as are all existing SLC drives. The MLC drives all use the JMF602 and the SLC drives use the Samsung S3C49RBX01 host controller with 32MB of on-board DRAM. The SLC drives are all priced above $640 for 64GB while the MLC drives are all under $300 for 64GB, Intel's 80GB MLC is priced in between the two (but closer to the SLC drives) at $595.
We'll soon see that Intel's price is justified in the market, but before doing that it's important to address an issue with these very tempting MLC drives...

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?Ph0b0s - Wednesday, September 10, 2008 - link
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 usingthese 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 agoYou 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!
