I have a 2017 MacBook Air with stock Apple 512GB SSD that I just inherited from my mother. I would like to upgrade it to 2TB. I'd rather avoid spending $349 on a Samsung EVO if I don't have to (for that price, I could buy a Feather M13 Turbo). The $250 price point is where I'd like to be. I was all excited about the
Sabrent Rocket 2TB because it is currently $230 on Amazon after coupon. However, now I'm a bit concerned. Are you saying that Sabrent won't work? Or are you just saying it won't work as well as the Samsung Evo?
Other 2TB sticks I am considering are:
All of those are in my price range so price is not my deciding factor among those three or the Sabrent. So, my question is which of those four (Adata, Toshiba, Crucial, or Sabrent Rocket) should I get? Or, is there another 2TB stick in that same price that I should consider?
Thanks in advance for your input.
For your Macbook Air.
Please note that your machine will at most do ~1400MB/s read/write. As the board can only handle PCIe Gen2 x4 lanes. There will be no reason to get a drive that perform better than that, as the bottleneck will be that.
What you might want to look into more is sustained write performance. (Bigger the DRAM cache ratio vs Capacity the better) You would also want to look into power consumption characteristics. For my main machine (rMBP 2015 15") It can do up to 3000MB/s due to it having PCIe Gen3 x4 slot. So I'm getting the most performing drive for it.
I'm not sure on which drives you listed use what controller. I'd research into what NAND they used, what endurance they are rated for. And how 'reliable' they are by glancing forums.
Now the sabrent had been a go-to for a lot of ppl here in this thread. But Samsung is the market leader when it comes to SSD. (their flagships are usually the ones that has fastest read/write, most IOPs, rated for most writes (?) for example; 1200TB rated for 2TB 970 evo plus)
Personally, I've always used Samsung drives for my past Macbooks (starting with 840 Pro for my first MBP late 2008)
I switched away from them (970 Pro 512GB) on my current 15" due to its tendency to hog power when ASPM is disabled. (It basically halved my battery runtime) But now that I can use them with ASPM. That's no longer the issue, and it makes Samsung drives one of the most efficient SSD around again.
For reference:
(I managed 6+ hr on a 11" MBA 2015 I delegated my 970 Pro with ~3-4W idle power, which is a significant improvement from before NVMeFix kext ~9W idle)
The 2TB Sabrent turns out to be quite the power hog also, with 11W consumption for active load (my 1TB Sabrent only has 8W load). (I pulled this number from smartmontools Power stat table) check my earlier comments for stats.
The other factor is the support that comes with the drives.
Samsung has its own Chip, with its own software, with a pretty decent firmware update utility/dedicated ISO.
Which is arguably pretty stable/mature. While Sabrent drives are basically another Phison-E12 based drives like a lot of other brands.
Now there is nothing wrong with that, but it makes it pretty confusing when it comes to firmware upgrade (firmware numbers are all over the place w/ different version with some cross-compatible, and some are not)
Also, different vendor may/maynot push firmware updates or push them slower/faster than another on essentially the same drive designs)
Furthermore, Sabrent utilities crashed on me 50% of the time I try to use it (When it worked. it tried to tell me it Doesn't know info about the newer 2TB drive with their latest utility I downloaded) that's not exactly re-assuring to me.
Don't get me wrong, Sabrent drives are pretty good (My primary had been running on Sabrent Rocket 1 TB for a year and it never failed me so far). But considering that they 'silently pushed' a significantly nerfed newer SKUs with basically 1/4th the DRAM cache it supposed to have. (ratio should be at least 1GB of DRAM per 1TB of storage)
(For comparison, 970 Evo plus 2 TB has 2GB of DRAM cache, as well as Sabrent's 2TB earlier revisions, but now only have 512MB!!) (cue the horror on my face when I realized that)
From realizing this, I felt betrayed. And I am most likely would not continue buying their drives (Or any Phison-based drives) into the future, due to potentially lower sustained performance, espc once DRAM is full.
I suppose it could be brand loyalty thing. But I have more trust in Samsung's SSD.
