    I had high hopes for this unit mainly down to the transfer speeds but it just gets almost untouchably hot and so painfully slow that it is beyond use.

    I have tried multiple drive formats but nothing changes the overall outcome, it still remains slow and very hot indeed

    This is my review of the 2TB model.

    I’d like to start by explaining some details of how SSDs work, the best ones (Most expensive ones!) have SLC (Single level Cells) then the next best have DLC (Dual Level Cells), then TLC (Three Level cells) and then there’s QLC (Quad level Cells). SLC drives tend to have a very limited capacity (in the Gigabytes not Terrabytes).

    SLC are fastest and most stable. But as you can store less data on them, they cost significantly more. QLC are not very fast at all. Top level SLC based SSDs will have some normal RAM to act as a cache for the data before it gets written to the SLC.

    The X8 is QLC based, and has no RAM to act as a cache. It therefore does a little trick where the controller software, will designate some of the QLC storage area as Pseudo SLC, (Caching data in the same was a RAM would) this will give greater speeds until this Cache gets filled up with data waiting for it to be written to the slow QLC. This is why some reviewers mention the…

    Like a lot of people I own a modern MacBook Pro (mine is the 2018 15″ version which has 4 x Thunderbolt 3 ports), which you are totally scalped if you want more than 256GB of flash storage. I upgraded from a 2012 MacBook Pro, so really missed the capacity of the SATA SSD I had upgraded that to. I bootcamp my Macs too, which exacerbates the problem. Unlike the old MacBook Pros, the internal storage on modern ones aren’t user upgradeable, which is where this beauty comes in!

    I was lucky enough to wait (and WAIT!) for the price to drop around Black Friday, so I got the 1TB model for not much more than the normal price of the 500GB model. I’m so chuffed my patience paid off.

    The packaging is normal Crucial minimalistic and environmentally friendly other than the plastic the SSD is wrapped in.

    Inside the box you get:

    The Crucial X8 SSD
    A user manual
    A dual purpose cable

    The SSD itself is a really lovely and tactile design. Other than two slim plastic inserts for branding and model/serial…

    This drive is built using QLC flash. QLC can NEVER write at 1050MB/s It wasn’t designed to.

    Crucial get round that problem by changing the mode of some QLC to work as ‘Pseudo’ SLC write cache. This Cache can write at the advertised speed. The SLC cache is allocated from available QLC.

    The problem with TimeMachine is that it fills the drive with backup snapshots till the drive is near full and then it starts overwriting the oldest snapshots with recent snapshots. Simply put – Time machine is designed to keep a drive almost full.

    But full drive means no room for SLC cache so drive can only write at QLC speed. (less than 200MB/s

    This is not sour grapes. It’s a simple fact that these low cost QLC drives with pseudo SLC write cache can never work at anywhere near the advertised write speeds once the drive gets near full.

    So. if you want to just use the drive to build up a music, photo or video archive where fast reads are required then this drive is perfect. Buy it now.

    But if you’re a Mac…
