IRDM gen.2 SATA 2,5″ SSD

SSD IRDM gen.2 is an upgrade of the Iridium drive. The drive uses proven and reliable solutions – MLC memories and Phison S11 controller. The IRDM gen.2 drive will prove itself as a cache, but also as the main drive in computers for a wide range of applications.

Key features
  • Available capacities:
    120 GB 240 GB
  • 2,5" form factor
  • SATA III (6 Gb/s) interface
  • MLC NAND Flash technology
  • 3-year warranty limited by the TBW* parameter and free technical support

High performance

The IRDM gen.2 SSD offers solid performance, achieving sequential transfer speeds of up to 540 MB/s for reads and 520 MB/s for writes. With its classic 2.5″ format and SATA III interface, the IRDM gen.2 drive will find use in many solutions that do not have faster PCIe connectors.

Feel the difference

If your computer is running slower than it used to, replacing your HDD with an SSD is the easiest, yet cheapest way to change that. SSDs are faster because they make it easier to access data, which in turn speeds up boot-up and application loading times. SSDs are not only good for everyday use, but also for gaming – faster and smoother loading of data will make a significant difference to the level of gameplay and the smoothness of the game environment – there will be less stuttering.

Durable MLC

The IRDM Gen.2 drive is based on robust and high-performance NAND FLASH memories using MLC technology. These are up to 10 times more durable than the TLC memories used in standard consumer drives.

Quality & endurance

The IRDM SSD is based on high-performance 3D NAND Flash memories in MLC technology and the Phison S11 controller. Intensive testing and a skilful selection of components has made it possible to create a high-performance and durable drive. As a proof of the highest quality components and extraordinary attention to detail, the IRDM drive comes with a 3-year manufacturer’s warranty.

New IRDM gen. 2 SSD is using the updated version of MLC NAND flash.

Both drives are based on MLC NAND flash, which means they deliver good performance and reliability. The basic difference between them is a built-in DRAM cache in IRDM PRO. This makes IRDM much more suitable for professional use.

The actual storage capacity of solid state drive depends on the technology used. In the case of newer NAND FLASH technologies, the controller reserves space for the operations and execution of tasks that happen during the use of drive. As the latest NAND flash memory require larger system structures, the controller uses additional space to ensure correct operation of the wear levelling algorithms. In practice, this means longer SSD lifetime, optimized memory performance and significantly increased data security.

The percentage drop is determined by the amount of data written and the number of program/erase cycles. It often happens that the first percentage (from the maximum value of 100% to 99%) changes faster. The further percentage change should advance at a slower pace.

The purpose of heatsink is to reduce the SSD temperature which reduces the effect of thermal throttling. Thermal throttling effects in the SSD performance drop once it reaches certain temperature.

In some situations, slight slowdowns may be noticeable. They depend on the performance of the entire system. Since the processor must decrypt the encrypted data, this can affect the system or application launch speed.

Very often sudden freezes may result from driver issues or power management services within the operating system. Another reason may be that the drive is under massive load, causing internal garbage collection mechanisms to slow down the drive's operation. These mechanisms are activated in idle mode, but there may be cases when they operate while the drive is in use. If you are experiencing such problem, do not hesitate to contact us.

No, warranty for GOODRAM SSD is not limited by the TBW value.

Yes, the drive will be compatible with the SATA II interface, but its performance will be limited to performance, provided by SATA II interface.

To initialize a new SSD, perform the following steps:
- Check the disk connection: Make sure the SSD is properly connected to the SATA port and power in your computer.
- Manage disks: In Windows, press Windows + X and select "Disk Management".
- Initialize and format: In the Disk Management option, find the new disk marked as "Unallocated". Right-click on it and select "Initialize Disk". Then create a new volume and format it, selecting the NTFS or exFAT file system, depending on your needs.

To transfer data from an existing disk to a new SSD, you can use our SSD Optimum Tool, which we provide at the link
The disk cloning process using this tool includes several steps:
- Tool installation: Download and install the SSD Optimum Tool on your computer.
- Connecting the SSD: Make sure the new SSD is properly connected to the computer.
- Start cloning: Open the SSD Optimum Tool and select the disk cloning option. The tool will detect the source disk and the new SSD.
- Start the process: Follow the on-screen instructions to start the data copying process. This process may take some time, depending on the amount of data to be transferred.
- Completion and testing: After completing the cloning, restart the computer, setting the new SSD as the main boot disk in the BIOS, to check if everything works correctly.
Detailed instructions for using the program can be found on our blog.
