Acer Aspire 5 A515-54G hdd

Geagichi

It's says Acer Aspire 5 A515-54G cu procesor Intel® Core™ i5-10210U pana la 4.10 GHz Comet Lake, 15.6", Full HD, 8GB, 512GB SSD, NVIDIA® GeForce® MX250 2GB, Endless OS, Black.

My question is: WHAT TYPE AND MANUFACTURER IT IS THE HDD INSIDE? (SSD or M.2 NVMe)

JackE

There are several A515-54G submodels. It could be a 2.5" SSD or an m.2 SSD depending on the submodel. It's likely a 2.5" SSD from your description. The manufacturer could be Samsung or WesternDigital or HGST or Seagate or etc. But show me the link to the ad so I can confirm. Jack E/NJ

If they would write on the web site I would not be here. Why dont ACER make those SPECIFICATION PUBLIC into a MANUAL.PDF?

Da. Acest submodel pare să aibă o carte NV.2 m.2. Dar va funcționa numai la aproximativ jumătate din viteza maximă NVME cu maxim două lățimi de legătură PCIe sau aproximativ 8 Gb/s. Jack E/NJ

Yes. This submodel seems to have an m.2 NVME card. But will only operate at about half the maximum NVME speed with maximum two PCIe link widths or about 8Gb/s. Jack E/NJ

Thank you very much JacKE for your answer but how did you find out?

I don't understand, can you tell me where I can find that info?

JackE

On the site you posted. The 512GB SSD is an m.2 NVME The only other options non-m2 for this model are a 1TB or 2TB HDD. The PCIe link width is 2X  so the NVME will operate a half its rated maximum speed. Jack E/NJ

Thanks Jack E/NJ. And why did you said 
"But will only operate at about half the maximum NVME speed with maximum two PCIe link widths or about 8Gb/s. Jack E/NJ"?

JackE

Because max NVME card speed depends on using up to 4 PCIe bus lanes or links to the CPU on the mainboard. Each mainboard lane can accomodate 4Gb/s. So 4 lanes is 16Gb/s maximum NVME card  speed.

The A515-54G mainboard has only 2 PCIe lanes out 4 lanes available to the NVME card. So it will operate at 2/4 or half maximum speed.
