Q1. How do I determine if the product is included in the warranty?
Please refer to Innodisk’s warranty policy. If you need to check the product warranty, please go to warranty policy page.
Q2. What is the maintenance fee for products outside of the warranty?
The fee is calculated from the replacement materials plus an added NT$200 inspection fee.
Q3. What are the specifics of the RMA process?
Q4. How can I apply for an RMA?
There are two methods of applying for an RMA:
(1) MyInnodisk online RMA application:
Log in to your MyInnodisk account, from there you will be able to access the RMA application page. Follow the instructions of the RMA application and acquire your RMA authorization code. Securely package your product with the application form attached visibly to the outside and send to our maintenance center. (MyInnodisk is only for Innodisk’s customers. If you want to apply for an account, please ask your Innodisk sales representative.)
(2)Download and fill in the RMA application form:
Please fill in the RMA application form and provide product model, quantity and product status. E-mail to Innodisk maintenance center ([email protected]). After confirming your application, an RMA number will be provided. Please complete the RMA application form with contact information and address and attached the form to the package. Please send the product to the Innodisk maintenance center within 14 days after receiving the RMA authorization code. Shipping and insurance fee are paid by the customer.
Q5. What should I do if the same problem occurs after the product returns from RMA?
The product has passed the standard testing procedures before being returned to customer. If the problem is still unresolved, we suggest sending the product to FAE. They can check if there are any compatibility issues with your system.
Q6. How is the warranty after paid maintenance calculated?
We provide six months warranty after paid maintenance. If it is a separate maintenance issue, we will provide a separate quotation.
Q1. When is the P/E cycle of the SSD considered to have reached its limit?
The limit is reached when the limitations below is reached (MLC: cycles exceed 3000, iSLC: cycles exceed 20,000, SLC: cycles exceed 60,000)
Q2. What is the difference between SLC and MLC?
The main difference between SLC and MLC is the number of bits stored in each NAND cell. SLC stores 1 bit of data per cell, while MLC stores 2 bits per cell. SLC can be written up to 10 times that of MLC devices, but the data storage density is smaller. SLC SSD is usually used in high-end consumer product like servers while MLC SSD usually more prevalent in mainstream consumer products because of the lower price.
Q1. What is ECC?
ECC (Error Correcting Code) is a coding method for DRAM that allows for detection and correction of single bit memory errors. As these errors can severely impact performance, EEC memory is often used for server and other mission-critical applications.
Q7. Why is golden fingers turned black considered human error?
Every Innodisk DRAM PBC will go through a burn test before being shipped out. If it is a defective product, it will be shown in the test. The gold fingers usually turn black because of an incorrect plug-in or due to contaminants inside the motherboard connector.
Q3. When I buy a 128G SSD, why does the disk's capacity not reach 128G?
- The caculation of HDDs and SSDs are differrent. In a HDD, 1GB is 1,000,000,000 byte which is 10 to the 9th power. But each GB of SSD is 1,073,741,824 byte which is 2 to the 30th power. Due to the different calculation methods between an HDD and an SSD, SSDs will seem to have 7.37% less capacity than HDDs.
- Additionally, SSDs need to reserve some capacity to let the controller run algorithms such as ECC and Wear-leveling as a buffer to enhance its performance and life.
Q4. Why can an SSD be detected by the OS, but not by the iSMART tool?
An SSD's detection in the iSMART tool is through the SMART command of the ATA command. On some older platforms, there are SATA ports which are not native SATA ports. The bridge on these platforms are designed to only transfer SATA signals such as SATA2 to SATA3. Therefore, some of the bridges will block the SMART command which leads to the non-detection of the disk under the iSMART tool.
Q2. What platform might exhibit compatibility issues with DDR 400?
There might be compatability issues with AMD LX800. For this platform the DDR 333 is recommended as it has a much more reliable performance.
Q8. What is the procedure if the defective product is not purchased from Innodisk or direct affiliates?
Please ask the original vendor to apply for an Innodisk RMA.
Storage - Q1.Why is the USB device connected to EMPU-3201/3401 not recognized by the OS?
Please check the power supplied to the USB device, EMPU-3201/3401 can supply port1 and port2 200mA by default. However, if the devices needs a current over 200mA, you need to provide external power to the EMPU module.
Q5. Why do SSDs need 4K alignment?
Each NAND flash chip is divided into write units called pages. Normally, the size of a page is 4KB.
In traditional HDD caculations, the beginning of a partition starts from the 63rd sector, and is 31.5KB. Because 31.5KB cannot be equally divided into 4KB, it will cross over to a 2nd page when 1 page of data is written. Therefore, 4K alignment is necessary in order to have the lowest impact possible on SSD performance and lifespan.
Q3. Is DDR4 2400MT/s RDIMM backwards compatible with DDR4 2133MT/s platforms?
Yes. In a majority of cases the DDR4 2400MT/s modules are compatible with platforms designed for 2133. However, the modules will only have a maximum speed of 2133MT/s.
Storage - Q2.Does the EMPU-3201/3401 have a Linux driver?
Linux kernel after 2.6.31 have xHCI driver natively.
Q6. Will AHCI mode enhance SSD performance?
Yes, it will. The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host bus adapters in a non-implementation-specific manner. The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities, such as hot swapping and native command queuing, so that host systems can utilize them.
Storage - Q3.Why does the speed of devices connected to the EMPU-3201/3401 not reach USB 3.0 speeds on Window 7?
The USB host/device and the OS needs to support UASP for to reach full USB 3.0 speed, otherwise the USB devices will use BOT mode to transport data and will not be able to reach the speed of USB 3.0.
UASP is supported on Window 8 and above, if use Window 7, please contact your USB device manufacturer to obtain a UASP driver.
