MFT-3000 Series Flash Solid State Disks

MFT-3000 drives mate the MFT software layer with Mtron MOBI series Flash SSDs and use long-lived SLC Flash memory. When compared with the next step dowm - the MFT-1000 - MFT-3000 drives are built with single level cell flash memory which lasts ten times as long as MLC (Multi Level Cell) memory. Their random read performance is about 3% better than the MFT-1000 while their linear write speed, and thus the speed of MFT writes, is about 70% greater. In a typical read/write mix, MFT-3000s are about 25% faster than MFT-1000 drives.

The following graph shows the throughput of the Mobi 3000 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. Note how even a Mobi 3000 without MFT outperforms a 15,000 rpm SAS drive.

The following table demonstrates the point that the random read rate of a Mobi-3000 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 130 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 80 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.

The following graph shows the projected daily erase life capability based upon data size written. Clearly, when MFT enabled, the Mobi-3000 with SLC media can accept more than fifteen 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-3000 is an ideal solution for a broad spectrum of Servers and Workstations.

The following table compares the Mobi-3000 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 3000 is just a lot faster than hard disks.
