Ultimate SU740 Solid State Drive

The ADATA Ultimate SU740 solid state drive not only brings you increased capacity, but also ups the ante on efficiency and reliability. 

Equipped with 3D NAND memory and intelligent SLC caching, the SU740 reaches read/write speeds of up to 520/450MB per second.

3D NAND - High Capacity, Very Durable

Implementing advanced 3D NAND Flash, the SU740 features higher storage capacities up to 2TB, improved efficiency, and rugged reliability with better cost-performance ratios than ever. 

The SU740 also sports data protection and error correction technologies for a higher TBW (Total Bytes Written) rating.

Fast Transmissions

The SU740 features continuous read/write speeds of up to 520/450MB per second and supports SLC caching. 

It delivers random read/write performance of up to 50K/65K per second, which is 2.5 times faster than traditional hard drives, for seamless file transfers.

Accurate Transmissions

Low-Density-Parity-Check (LDPC) error correcting code has been implemented on the SU740, which helps to reduce data errors and an equal increase in data integrity. It therefore protects your valuable content against corruption.

The SSD Advantage - Robust & Whisper Quiet

Unlike a hard drive, the SU740 has no mechanical parts, making it more resilient against drops and bumps. It also has the advantages of being wide-temperature resistant (0°C ~ 70°C), whisper quiet, and power efficient. Make the switch to SSD and see the difference!

SSD Toolbox and Migration Utility

Every SU740 purchase qualifies for free downloads of ADATA SSD Toolbox and Migration Utility. 

SSD Toolbox allows users to monitor and manage the SU740, with drive status, wear level, and lifespan information. 

The Migration Utility is especially helpful for users making the move from HDD to SSD, as it is designed for simple and quick backup and migration of the contents of entire drives, including the operating system.

Q: Why is my SSDs capacity less than indicated on the packaging?

A: The difference in capacity is mainly due to the different calculation methods used by your PCs operating system and the SSD. 

SSDs calculate capacity based on the decimal system, 
e.g.: 1KB - 1000 Byte bytes, 1MB - 1000KB, 1GB - 1000MB, 1TB - 1000GB, and so on. 
Your PCs operating system uses the binary system, 
e.g. 1KB x 1024 Byte byte, 1MB x 1024KB, 1GB x 1024MB, 1TB x 1024GB, and so on.

For example, if the packaging shows capacity or 500GB, it is calculated as follows: 500GB x 500 x 1,000MB x 1,000KB x 1,000Byte x 500,000,000,000Byte. 
Your PCs operating system will calculate as follows: 500,000,000,000 Byte/1024KB/1024MB/1024GB, or approximately 465GB.

Q: What is the difference between SATA 3.0 and SATA 2.0?

A: According to the Serial ATA International Organization the SATA 3.0 specification offers transfer speeds up to 6Gbps compared to 3Gbps for SATA 2.0.  Regardless, SATA 2.0 and SATA 3.0 use the same interface and cables.
