Mtron MOBI-3000 Series Flash Solid State Disks

Mtron MOBI series Flash SSDs are designed to excel in Mobile applications such as laptop computers.  Featuring a rugged no-moving-parts design encased in a lightweight plastic housing, MOBI drives deliver enterprise performance in a small, lightweight package.  The read performance of Mtron MOBI drives is amazing.  Featuring sustained read rates of 100 Megabytes/sec and random IOPS of > 12,000 with 4K transfers, the MOBI series is one of the fastest SSDs you can buy.  This level of read performance takes the tedium out of computing.  Programs load faster.  Searches finish quicker.  Backups no longer take hours.  Never again will you need to defragment your laptop drive.  With Mtron MOBI at work, any sector on the disk is available in less than 100 microseconds or over 200 times as fast as traditional laptop drives.

When writing, the Mtron MOBI series is also designed for speed.  With sequential write speeds of 80 Megabytes/second you can load large media files quickly.  When randomly writing, MOBI drives write about 115 4k IOs per second. This is faster than a 7200 rpm disk drive, and about four times as fast as a typical SLC Flash Drive, but about a hundred times slower than the same drive used with MFT. From a pure performance perspective, applications that are read intensive will see disk throughput nearly 100x the speed of a typical laptop hard drive.  For update intensive applications, the Mtron MOBI series performs on-par or slightly better than a 15K SCSI drive.

When the MOBI-3000 is wedded with MFT, its performance and projected wear life increase dramatically. MFT improves typical random read and write IOPS performance by 15 times, while enhancing the projected random write life of the product more than 50-fold. This wear improvement is so dramatic that Mtron warrants the MOBI-3000 for server use when used with MFT, but specifically discourages its use in servers when MFT is not present.

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.

Mobi 3000 Performance Graph

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.

Aggregate IOPS without MFT 392 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-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.

100,000 Life Cycle Graph

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.

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.
