ADATA 1 TB SU750 SSD

The ADATA SU750 is a 2.5″ form factor $SATa 6 GB/s SSD. The ADATA SU750 comes in 256 GB, 512 GB, and 1 TB variants. The drive itself measures 100.45 in length x 69.85 in width x 7 mm in height. The drive weighs all of 47.5 grams. The front of the ADATA SU750 has the ADATA logo with the works “Ultimate Solid State Drive” printed directly below. The SU750 branding is displayed most predominantly on the front of the drive.  Towards the right of the drive is the ADATA bird logo. The logo that gets my vote for most adorable tech mascot.

The backside of the drive is where you’ll find the model number to your specific drive. This is also where you’ll find the serial number, or warranty code, as well as the WWN number, There is also a list of several certifications across the bottom of the label.  The SU750 has a sequential read speed of up to 550 MB/s and a sequential write speed of up to 520 MB/s. The SU750 has an MTBF, or mean time between failures of 2,000,000 hours. The safe operating temperature is between 0°c and 70°c. Safe storage temperature is between -40°c and 85°c.

The ADATA SU750 uses the standard SATA power and data connections. ADATA advertises sequential speeds of up to 550 MB/s on the read and up to 520 MB/s on the write for the SU750. This is obviously due to the capacity of the drive which is why we test the drive both empty and at 75% capacity. The SU750 has a 3-year limited warranty.

Like with all 2.5″ SSD reviews, we tear them down to see what the internals of the drive consists of. The SU750 was far easier to take apart than most. In fact, most ADATA SSDs come apart rather easy as the simply snap together. There are no screws that keep the two parts of the housing together. So all you need is a spudger and patients to get the SU750 apart.

For the SU750, ADATA used the Realtek RTS5733DMQ controller. The SU750 is a DRAM-less drive and uses four ADATA memory modules. The SU750 uses 3D TLC or triple-level cell Nand.  TLC Nand stores three bits per cell, or triple that of SLC, or single-layer cell Nand. Although TLC Nand is the cheapest type of Nand to produce, it also has, on average, a shorter life span than MLC, or Multi-Level Cell Nand. TLC NAND is perfect for consumer SSD’s as with using TLC Nand, companies can produce cheaper SSDs for the end-user. However, due to the shorter life span, enterprise SSD’s will hardly, if ever, use TLC Nand. The average life span of TLC NAND is about 3,000 – 5,000 cycles per cell. Compare this to SLC NAND at 10,000 cycles per cell and you can see how and why TLC drives have on average, a lower MSRP.

The SU750 has support for SLC-caching. SLC-caching is used to speed up the read and write speeds of TLC based SSDs. With SLC-Caching, when the drive is at a lower capacity, workloads will stay within the SLC cache. The more the drive fills up, it could see slower write speeds, but only when the drive is over 75% capacity. There are four ADATA memory modules on the SU750, two on either side of the PCB.
