Mtron MOBI-1000 Series MLC Flash Solid State Disks with MFT
|
Mtron has delayed the world wide general release of the 1000 series pending further testing with customer applications. Their concerns revolve around the slower write performance and lower drive life spans that are inherent in all MLC Flash SSDs. We agree with Mtron that MLC drives require careful deployment with applications that are designed specifically for MLC Flash drives.
EasyCo has made arrangements to distribute the Mtron 1000 series drive with immediate availability when this drive is used with EasyCo's MFT software layer. Mtron and EasyCo have done extensive testing of the 1000 series drives with the following results:
* Random writes are accelerated 100x to 350x
* Overall random IOPS performance is increased 60-fold
* Real-world life span is extended over 50-fold
This positions the 1000 series drive squarely as an ideal solution for laptop, workstation, and even mainstream server usage. It also allows for direct replacement of 15,000 rpm SAS arrays with Flash SSD with:
* 27% lower cost/GB
* 15x faster aggregate read/write IOPS
The MOBI-1000 with MFT also dramatically outperforms any other Flash drive. Though only about half the cost, it outperforms premium-performance SLC drives by between 7:1 and 12:1. Similarly, it offers a 10-fold longer wear life at about half the cost. When contrasted with other MLC drives running without MFT, the MOBI-100 with MFT outperforms these by between 25:1 and 400:1, and extends useful write life by between 50:1 and 400:1 depending upon the model tested.

The following graph shows the throughput of the Mobi 1000 drive both as a bare drive, and with the same drive MFT-enabled. 15,000 rpm and 7,200 rpm hard disk performance is shown for comparison purposes.
|
|
The following table demonstrates the point that the random read rate of a Mobi-1000 is extremely fast. A 15,000 rpm hard drive performs only about 250 random reads a second, and a 7,200 rpm hard drive only delivers 70. As a result, the Mobi's random read is literally 100 times faster than that of a Laptop hard drive. But the table also shows that the Mobi's native random write capability is literally as much as 400 times slower than its random read.
The table also shows how MFT's linear method of random writing improves random write speed almost to the random read rate. |

Higher is better. A single 15,000 rpm SAS drive has a value of 250, and a 7,200 rpm SATA drive rates at 70. Click here for explanation of calculation methodology. |

The following graph shows the projected daily erase life capability based upon data size written. Clearly, when MFT enabled, the Mobi-1000 can accept more than one and a half overwrites of the entire drive on a daily basis, no matter what the data size, and still be expected to last five years. Given that the vast majority of servers overwrite less than 20% of their surface a day, it is clear that an MFT enabled Mobi-1000 is an ideal solution for a broad spectrum of Servers and Workstations.

 |
The following table compares the Mobi-1000 both MFT enabled and bare with the reasonable write throughput of different hard disks. It also looks at the duty cycle to complete the work shown. This, in another way, makes the point that when MFT enabled, the Mobi 1000 is just a lot faster than hard disks.

Thruput per day is based upon an average data size of 10.66kb and a read/write mix of 70% reads and 30% writes. The values shown for the 7,200 and 15,000 rpm Hard Disks are the maximum possible attainable values if these drives are run at 100% duty cycle 7x24. Values for the flash media are calculated as described here. Here, the limit to throughput is not time, but rather the number of safely available write cycles based upon a goal-life of at least five years. |
