Sony is no exception when it comes to producing high quality products especially when they fall into the audio, mobile and TV categories. Now, the company has decided to tap into the SSD market, with its latest products being called SLW-M series.


SLW-M Series From SONY Use The SATA 3.0 Interface And Deliver Impressive Read And Write Speeds

Sony has introduced two capacity models, and they have been listed below:

  • SLW-MG2: 240GB
  • SLW-MG4: 480GB

The SSDs use a 2.5 inch form factor and since they use a SATA 3.0 interface, they will obviously deliver high read and write speeds. Keep in mind that these speeds will obviously be lower as opposed to those that use the PCI-E interface, but they are still impressive regardless. Coming to the actual metrics, these solid state drives will be able to deliver up to 560MB/s sequential read and 530MB/s sequential write speeds. Sony has not managed to list the random read and write speeds, which is common practice, primarily because it discourages the consumer from purchasing the drive due to those lower speeds.



In addition, the aforementioned speeds have been achieved based on the company’s own internal testing environment, and having said that, it is definitely possible that the testing environment will be extremely different compared to yours, thus resulting in different speeds. Coming to additional details of what is present inside these blazing fast storage modules, Sony SLW-M SSDs are based on the Phison PS3110-S10 controller as well as Toshiba’s TLC flash memory. The use of TLC NAND indicates that Sony’s SLW-M are entry-level client solid-state solutions, since they do not cost a lot of money to money to make as opposed to SLC solutions, which are normally targeted to enterprises.

Additionally, we should point out that these SSDs have not taken the same approach as Samsung’s V-NAND flash memory, which not only increases reliability, but overall read and write speeds as well. We were hoping to see that Sony incorporated this approach so that consumers have a better reason to invest their funds in the latest storage products, but we are sure that the company had its reasons. Pricing details have not been detailed, but we will get to know in the coming months.
