I saw a guy post about the lack of SSD reviews. I thought that the ioDrive from Fusion-IO is unique enough to merit a post. This review shows a PCI-E SSD that has 4X more performance than any other SSD. One server tests shows it 170X faster than a 10K RPM Raptor HDD!

I want one!

Yes, finally a drive that looks like it will actually live up to the hype. I really want one. I guess I will have to go to Vista 64 to get it, and I want to boot from it too.

Why so much difference between HDtach & ATTO ?

That is a $3K drive for 80GB. Waste of money i believe for an end user. Good for being a guinea pig though. Each and every SSD was groundbreaking since 2 years... Yet we still have nothing that works.

Besides, you will be needing a secondary drive on your system... And for bigger file operations, that disk will be used due to its capacity (movies, entertainment, etc). Your system will feel still slow since majority of high throughput file operations will be done on the 2nd drive.

Better to wait another year while it explodes on people's systems and matures. I would pay $1000 for 320GB. Those are stellar numbers.

Does anyone know what file system they're using in these benchmarks? It seems like this device should have maintained a high level of throughput even when the block size was very small due to its extremely low access time. Unless they were using a filesystem with a minimum cluster size much greater than their block size and the throughput was being wasted over-reading.

[gfody]

Notice how peak throughput is achieved at 32kb. I think this is due to them testing a volume formatted NTFS with 32kb clusters. At each block size less than 32kb the drive is over-reading and throughput nearly halves (some is reclaimed due to overlapped IO and NCQ). In spite of that the drive is doing 400mb/sec with 8kb IOs. Insane!

I would really like some REAL benchmarks from a neutral source.
While i appreciate the link in the OP, a page which proclaims itself as the sole distributed of the reviewed product doesnt really readiate credibility.

Is a Database benchmark good enough for you? This was out many months ago.

We finally got a Fusion IO-Drive to test and found it had two distinct modes.

When it is "Empty" it performs very well (as advertised). There are probably no Erases going on or any garbage collection.

After enough Writes to fill it up, it changes to "garbage collection" mode. Write bandwidth drops to 20 MByte/sec (5K IOPS), 90% less than when it is "Empty".

So, it seems the "Sustainable Random Write IOPS" is 5K.... similar to other SSDs.

[Loomy]

90% is a big performance drop. Performance dropping 90% when it hits a certain not-full capacity level would not be good. For consistent performance the required buffer space should be reserved and not displayed to the user.

How full was it when the performance dropped?
