| 9.SAS VS SATA |
|
1.SAS - Serial Attached SCSI port is downward compatible with SATA port. SATA controller can't support SAS drives.
2.SAS use the same physical connector as SATA. So it's hot swap from SAS drives by SATA drives.
3.SAS controller can support SAS and SATA drives in mix in one system environment.
4.SATA 3.5" and SATA 2.5" use the same connector and cable. We have 3.5" frame kit for customers to install MemoRight's 2.5" SSD into 3.5" bay |

| 8.Do your SSDs have Secure Erase feature? |
|
There are two types of "disk erase".
A. Non-Destructive Erase: By writing the whole disk with "0" for clean up purpose. So a 32GB SSD needs around 327sec=32GB*1024/100MB/s. The SSD will remain in a reusable condition after the Non-Destructive Erase.
B. Destructive-Erase. By pumping the electricity into the SSD to destroy all the flash chips. It takes around 1-2 seconds. The SSD will be in a non-reusable condition. This function needs customized engineering works to address each different customers application requirements.

| 7.How can I test an SSD in a more practical way? |
|
Basically there are four major performance indexes for a drive, sustain read, sustain write, random read and random write. According to Flash¡¯s characteristic, reading is much faster then HDD but writing is much slower than HDD due to each write to the Flash needs an erase cycle. So the writing performance for an SSD is very key to the overall throughput for the Third party testing tools like HDtune and HDtach are good for performance reference but we believe the IOmeter is the one which can simulate your actual application environment most. The rule for IOmeter testing is to set the random read/write rate mix according to your daily application, only then will you get the result pretty close to your future operations.system since one slow write request will kill the advantages contributed by 100 reads. |

| 6.Why can¡¯t my PC recognize my SATA Drive in the BIOS? |
|
There are two modes of SATA Drive in the system BIOS setting, AHCI mode and Compatible mode. You have set the BIOS in ¡°Compatible Mode¡± for using MemoRight SATA SSD. |
|
|
|
| 5.Why does the formatted capacity of a 32GB SSD reduce to 30GB£¿ |
|
The hidden 2GB is reserved for the ¡°Bad Block¡± management. This is the industrial standard and is also apparent with traditional HDD.¡¡ |
|
|
|
| 4. Does MemoRight's SSD have more than 10 years life cycle? |
|
Taking 32G SSD as an example, the committed erase(write request) time from original flash chip suppliers at 10M times. Assume daily writing 500G then 32GX10M times/500G/365 days=17.53 years. Of course, writing 500G daily is an extreme case for an average daily usage of a typical drive. |
|
|
|
| 3£®Why is my IOPS readings of IOmeter is different from those published by MemoRight? |
|
There are two methods to test the IOmeter, one is ¡°Raw Drive¡± and other one is ¡°File System¡±. You have to test the IOmeter on the SSD in ¡°Raw Drive¡± mode. Otherwise the test will only be conducted on a particular ¡°File¡±. |
|
|
|
| 2£®Why can't my system recognize the SSD drive in DMA6 mode during the installation? |
|
The first thing you have to check is the cable. You should use 80PIN cable instead of 40PIN and sometimes the quality of the cable is another cause of this problem.
Second, you have to set the BIOS setting to ¡°AOTO¡±¡£ |

| 1. What are the current available models from MemoRight? |
|
There is one series in production,SATA interface with 32/64/128GB. |
