EasyCo 1000 Series MLC Flash Solid State Disks with MFT
|
|
Mtron has delayed the world wide general release of their 1000 series MLC Flash SSD in order to do more to improve their random write performance. (The Mtron Mobi 1000 has superb randon read performance is superb, which is typically three to four times as fast as any other MLC Flash disk we have tested). In the mean time, after extensive testing by both EasyCo and Mtron, Mtron have appointed EasyCo as private label marketer of this drive series because MFT avoids the performance concerns Mtron have had.
When the series 1000 drive and MFT are combined, random write performance jumps 100 to 350 fold, and the overall performance of the 1000 drive jumps more than 60 fold to a rating of 4776. This is almost twenty times as fast as a 15,000 rpm SAS Hard Disk, and more than 60 times as fast as the hard disks commonly used in workstations.
Similarly, the effective erase life of the 1000 with MFT increases more than 50-fold from that expected of the base 1000 model. As a result, the 1000 drive with MFT can be used with an expectancy of seven years (or more) of life provided that the drive is over-written with new data less than once a day on average. This means that this drive with MFT is practically suited for any Workstation, as well as about 95% of all servers.
The reason we have pushed for distribution of this drive is that in addition to being well built, it is 2 times as fast as any other MLC drive we have tested to date, and 2.5 times as fast as most. That's important to us and our customers because it lets us deliver high performance at low cost.
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
* 19x faster aggregate read/write IOPS

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 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 1000's random read is literally 100 times faster than that of a Laptop hard drive. But the table also shows that the 1000'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 EasyCo 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 EasyCo 1000 is an ideal solution for a broad spectrum of Servers and Workstations.

The following table compares the EasyCo 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 EasyCo 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. |
