Cheap SSD Buying Tips - Adata SU650 review

Get cheap SSD purchase tips

SSDs cheaper, but it's a trick!

The price of SSDs has dropped a lot lately, due to the production that has increased a lot, and the capacity of the faces is more and more. - Cheap SSD Buying Tips

Not only does it store multiple bits on the same cell, but also multiplies the number of layers. Practically put the layers of cells on top of each other.

SSDs are like homes!

A good analogy would be living spaces. A NAND memory is like a living space, where people in a building are the data.

Imagine that the first single-layer NAND SLC memories were like a studio in a one-storey building, and NAND QLC memory is a suite of rooms in a building with 96 floors.

Resistance or rewrite cycles!

Each time you write and erase, the cell on the SSD is worn out. Older generations, that is, the SLC NAND was more resilient, because a cell was written and deleted less often, because I had one bit on the cell.

At new NAND, cell wear is more accelerated, because a cell is accessed more often.

Cycles for rewriting to different types of NAND:

  1. NLC SLC memory - 100.000 rewrites
  2. Nand MLC memory - 10.000 rewrites
  3. Nand TLC memory - 3000 rewrites
  4. Nand QLC memory - 1000 rewrites

NAND memory cycles are like the front door! - Cheap SSD Buying Tips

To continue the analogy, the rewrite cycles are like the entrance door in a block. The more locals use it, the faster they wear out.

My cheap SSD recommendation! - Cheap SSD Buying Tips

Addition of SU650 is an SSD entry level, but with NAND more robust than other cheap SSDs from other brands.

    Hi, what do you think of Kingston uv500 SSD for windows and some games?

  2. wolfwarine said

    Hello Cristi
    Very useful tutorial. I have an 650 drive and sincerely for a year I have had no problems with it. I honestly did not know what acronyms mean and what are the differences between them.

  3. wolfwarine said

    However, I have a question: exactly in the specifications where should we look to see if it has or not that RAM you talked about in the tutorial? On emag, for example, I did not find anything in the specifications for ADATA like this. Should it write cache or memory or…?

  4. Adrian Gudus said

    You can usually find this specification in the specifications section under "Memory Type"

  5. Hello, a good and cheap SSD for your laptop if you can recommend it to me?

  6. Hi Adi, and what do you do if there is contradictory information, I looked for references for this model (WDS480G2G0B), I did not find a concrete specification of the type of memory, on some sites it is SLC, on others TLC and on the official site neither a reference to such a thing …… .I have a dilemma in this regard, it is quite possible that some put these specifications only for the sake of selling the product (eg it may be TLC and in the specifications to be passed SLC.
    You have a method eg. to specifically check what type of memory it is?

  7. I have this SSD and I want to use it for system and storage. The base plate is MSI Z77A-G43 (MS-7758). The question is whether this SSD is compatible with the motherboard and whether it is a good SSD. The processor is Intel Core i5 3570K @ 3.40GHz

    Sorry I forgot to give what SSD I have. I have this SSD SAMSUNG - 860 QVO - 1To - 2,5 ″ (MZ-76Q1T0BW) and I want to use it for system and storage. The motherboard is MSI Z77A-G43 (MS- 7758) .The question is whether this SSD is compatible with the motherboard and whether it is a good SSD.The processor is Intel Core i5 3570K @ 3.40GHz

  9. Marian said I have a Ssd Kingston a400 240 GB, I have now seen on the site that it is with TLC memory site also writes that it is with the type of controller on two channels, what does it refer to? I put in a laptop Lenovo this ssd, I am pleased with how it moves, but I wonder how many years I would keep, not to wake up one day when I can not access laptop data anymore; is this scenario possible?

    Greetings to all. I recommend 2 SSDs:
    - SSD Patriot VPN100 256GB PCI Express x4 M.2 2280; new model, launched this year, where Endurance / Resistance in time or that TBW (Total Bytes Written) is 380 TB! I leave it to you to draw conclusions compared to other SSDs from other companies.
    - SSD Patriot Burst 240GB SATA-III 2.5 inch; Endurance / TBW is 180 TB.

  13. Ultimate SU650 added a bad SSD after a few months of normal use has not started. I lost the last data I did not back up. He did not give any sign that he would. It's a shame to advertise such a brand even if you gave it for free (for testing)

  14. At the very least you can say that your SSD is bad, and you seem to be the same if you did not save your data and you're going here, the rest of your statements are pure speculation, and after all the SSD or HDD is perfect and to leave critical data without backup?

    Hello Cristi,
    What do you think of the 4bit MLC NAND - of this ssd Samsung 870 QVO SATA3 (MZ-77Q1T0BW), has a very good write and read speed, respectively 560/530 MB / s and an affordable price. I paid 1 lei for this 440TB ssd and I am very satisfied. Of course, your tutorial was also very helpful. If you think it's worth it you can update the tutorial for this product, I'm very satisfied.

      PS: I forgot to specify that it also has 1 GB Low Power DDR4 SDRAM is compatible with SATA 3 and a state-of-the-art Samsung MKX controller
