Just trying to figure out what is the difference between M.2 PCIe NVMe and M.2 2280, PCIe-NVMe, TLC ??

I need to choose one.

I mean which one is better?

  • Is it just the length of the chip in mm? And no difference in the performance?

    All the "facts" of the latter one also apply to the other one. The only distinction would be TLC, which results in 3 bits being stored per cell, and usually results in slightly lower speed and durability compared to SLC SSDs - which only store one bit per physical cell. Chances are the other one is TLC too though, especially since it's the same price.

    It seems like both 256GB and both 512GB SSDs could be duplicate options in their system because they are the same price, but they could be different models/brands! You should ask this retailer/company what the difference is because the first option could also be a 2280 (22mm x 80mm) SSD with TLC memory. No way to know without the exact model number.

Repeating comments as an answer.

2280 is the size designation for an M.2 card, such as an SSD. This is the typical size for a PC.

TLC is the type of memory used in the drive. It stands for Three Level Cell which means that each cell holds three bits. This is again typical for a consumer drive. MLCs, with two bits per cell, are used in high-end drives like the Samsung Pro series, while QLC, with four bits, are used in low-end drives like the Intel 660p.

While this is likely a duplicate entry, but personally I would pick the one with more details, otherwise you could get a terribly overpriced Intel 660p.

If that price is in USD the drive is expensive anyways - if you can and are able to put in the drive yourself, get something like the Kingston A2000 which has a suggested price of 99 USD for a 1 TB model. It should be good enough for any non professional uses.

  • Thanks for kind reply and comments @Jan. Well, I can't buy separately as trying to buy a Lenovo machine here in New Zealand and these are the options in the customization that I can chose/change. Will ask for more details though. Appreciated :)

    @ViKiNG I just looked at a quick conversion which says 150 NZD is 100 USD - that disk is still overpriced unless it's a high-end TLC. Nov 27 '19 at 15:59
  • Thanks Jan. Much appreciated :). I'll make sure if it's worth buying :)

    @ViKiNG if you want to play games you don't have much choice - unless there are other drives available - since 256 GB is too little for modern games. Nov 28 '19 at 10:09
  • Strongly Agreed.
