ADATA SU900 vs SU800: Which Solid State Drives Are Better?

The average PC game takes between 40GB and 50GB, a movie 1.6GB, and each app can be around 465MB. Individually, it doesn’t sound like a lot, but when you start adding up all you have, plus any photos and videos, you can see how your storage space is quickly used up. This leads to poor-performing devices and even the risk of losing your crucial data.

USBs and external hard drives have been fine, but why settle when you can upgrade to an internal solid state drive for improved performance and reliability. We are going to compare two examples, the ADATA SU900 vs ADATA SU800. We will look at specifications like size and capacities, speeds, technology, and durability. With a side-by-side chart and some pros and cons, we will decide which is the better solid state drive.

There are various similarities between the ADATA SU900 and the ADATA SU800. We will start with these features.

Appearance

Aside from the ADATA SU900 being gold and the ADATA SU800 being blue, the SSDs are identical. They measure 3.95 x 2.75 x 0.28 inches and weigh just 1.6 ounces. They have a 2.5-inch form factor.

SATA 6.0 Gb/s

Both the ADATA SU900 and the ADATA SU800 are third-generation SATA 6.0 Gb/s solid state drives. They have a bandwidth of up to 600MB/s and are backward compatible with SATA I and SATA II.

Cache

The cache of an SSD is temporary storage for quicker access. The ADATA SU900 and the ADATA SU800 use SLC caching that transfers one bit of data per cell. This is in addition to the DRAM memory cache buffer for faster transfer speeds and improved performance.

Mean Time Before Failure (MTBF)

The mean time before failure is an estimated number of hours before you may run into issues. The mean time before failure for the ADATA SU900 and the ADATA SU800 is 2 million hours.

Durability

The long MTBF is helped by the shock and heat resistance of the ADATA SU900 and the ADATA SU800. The drives are shock-resistant at up to 1500G/0.5ms. They can also withhold operating temperatures from 0ºC to 70ºC.

Now we will move on to how the ADATA SU900 and the ADATA SU800 differ.

It’s not really a deciding factor as the storage capacity will depend on your needs, plus the difference is very small.

ADATA SU900

There are 5 drives, 128GB, 256GB, 512GB, 1TB, and 2TB.

ADATA SU800

There are also 5 drives, the difference is instead of 256GB, there is a 250GB drive.

These solid state drives come with a good range of technology and software.

ADATA SU900

This is a 3D MLC (multi-level cell) NAND drive with RAID Engine and Data Shaping for security, LDCP EEC (low-density parity-check error-correcting code) to significantly reduce data errors. DEVSLP lowers the power consumption while the ADATA Toolbox software allows for monitoring and managing the drives. It also has a Migration Utility for software backup.

ADATA SU800

The technology is the same with the exception of Migration Utility.

The Winner Is- The ADATA SU900

We looked at the price and the warranty to determine the value for money.

ADATA SU900

There is a 5-year limited warranty with all storage capacities. It’s a more expensive series, with the 128TB costing around the same as the 250GB ADATA SU800.

ADATA SU800

Although they are cheaper, the warranty is only for three years.

The Winner Is- A Tie

Finally, we have some pros and cons of the ADATA SU900 and the ADATA SU800.
