Hi,

I found that the newest SSD DC S3520 has slight changes on the current consumption showed on the label of the SSD.

Originally, the SSD had the +5V with the 2.0A and +5V/+12V with 1.0A/0.5A.

Currently, the label on the SSD shows that +5V with 0.6A and +5V/+12V with 0.3A/0.7A.

Could anyone please advise on the followings,

- What is the VDC? Voltage input?

- What is the AMPS? Max Current on the certain VDC?

- Would there be any significant impact to the user's CPU?

- What is the advantage of improving the current?

Thank you!

Regards,

Chin Yong

Hello Chin Yong,

Thank you for your interest in the Intel® SSD DC S3520 Series. I understand that you have several questions regarding the VDC and AMPS values present in the SSD's labels. VDC is an abbreviation for volts direct current, this means that the SSD should be powered with a constant voltage. For your particular SSD, this voltage can be either +5 V or +12 V. AMPS is used to denote amperes, which is the basic unit of electric current. This value represents the current used by the SSD to operate. Since the current required by your SSD varies depending on the workload, a specific value may be required by the SSD at a given time, so the label shows the typical value as well as minimum values. In the first picture (ISN: PHDV647600YP150MGN) 2.0 A indicates the typical value drawn by the SSD when it is powered by +5 V. The second picture (ISN: BTDV74220G63150MGN) shows that 0.6 A are typically required by the SSD when connected to the same + 5 V power supply.

For each VDC value, there is a minimum current required for operation, and that is the additional information shown in the label. Here is the same information shown on the label but pointing out the previous descriptions:

ISN VDC [V]Typical AMPS [A] Minimum AMPS [A] PHDV647600YP150MGN + 52.01.0+ 12-0.5BTDV74220G63150MGN+ 50.60.3+ 12-0.07

Regarding the difference in values between the two labels of the same SSD, I'll keep investigating and get back to you as soon as I have relevant information.

Thank you for your patience. Regards,Andres V.

Hi Andres,

Please correct me if my statements were wrong,

1) The "change" of the AMPS value is not a change, but in fact, there is just a correction made on the labels only

2) There is no any firmware/hardware update, which has improved the AMPS value from the higher current consumption (ISN: PHDV647600YP150MGN) to lower current consumption (ISN: BTDV74220G63150MGN).

Thank you!

Hello Chin Yong,

Both your statements are correct, the AMPS value change is a label correction, and it does not reflect any change, neither on a hardware nor a software level.Regards,Andres V.
