IRDM gen. 2 SATA III 2,5″ SSD
IRDM GEN. 2 SSD is an upgrade to the Iridium SSD. GEN. 2 SSD is based on proven and reliable combination – MLC NAND flash and Phison S11 controller. IRDM is suitable to operate both as a cache memory and a main drive in 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 + technical support
Reliable MLC NAND flash
IRDM SSD design is based on robust and efficient MLC NAND flash memory. They are up to 10x more durable than the TLC NAND flash used in standard consumer drives.
Solid and universal
SSD IRDM offers solid parameters by reaching up to 540 MB/s for sequential read and 520 MB/s for sequential write. By using classic 2.5” form factor with SATA III interface, IRDM SSD can be widely adopted in older or less advanced applications that lack the PCIe connector or doesn’t require the highest level of performance.
Quality
IRDM SSD is built around selected MLC NAND memory chips and Phison S11 dual-channel controller. Detailed tests and selection of components made it possible to create an efficient
and durable SSD.

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.
