Crucial P5 2TB NVMe M.2 SSD $238.50, Seagate BarraCuda Q5 2TB NVMe M.2 SSD $189 (Expired) Posted + Surcharge @ Shopping Express

180

Two M.2 NVMe SSDs on sale with the Seagate on sale from 9-10pm AEST as part of Epic Hour, while the Crucial is part of the 10% off sitewide sale. Both have free delivery.

The Crucial P5 is a PCIe 3.0 SSD (not for PS5) SSD with a seq. read/write of 3400/3000 MB/s, TLC or QLC flash, 2GB of DRAM cache and 1200TB endurance.

The Seagate BarraCuda Q5 is a PCIe 3.0 SSD (not for PS5) with with a seq. read/write of 2400/1800 MB/s, QLC flash, no DRAM cache and 531TB endurance.

Out of the two the Crucial P5 is the better one offering faster speeds, DRAM cache and higher endurance, while the BarraCuda Q5 has slower speeds, no DRAM and lower endurance. The BarraCuda Q5 would still be good for something not requiring a lot of writes, such as a Steam drive.

  • Crucial P5 is TLC

    • People always throwing up different answers with Crucial. TLC it is then.

      • Only concern for me is the P5 very hot

        • NVMe SSDs in general run hot. Heatsinks are cheap.

    • There's another OzB-er https://www.ozbargain.com.au/comment/12308254/redir who cited a TomsHardware article, that the current production has since switched to QLC…

      • That's P2, this is P5. That said, Crucial's naming for their NVMe is weird and inconsistent.

        • cheers mate, thank you for highlighting this, sorry I misread
          Thank you for pointing this out :). Cheers mate :)

  • $332.10 for the P5 plus is a pretty good price too!

    • -1

      Nearly an extra $100 for performance you're not going to notice in normal desktop usage?

      • It's compatible with PS5 which is definitely a big plus for some people.

  • Are these decent for a gaming laptop

      Based on Tom's hardware's review, it is not the best choice: runs hot is one of the cons. The thermal performance is a factor you generally want to consider for a laptop (unless your gaming laptop has good cooling for the m.2 NVMe slot).

      Quoting the review (page 2):

      The P5 runs hot. At idle, the Crucial P5's controller hovers around 50C. That's 10-15C higher than most M.2 NVMe SSDs. After we threw a few 50GB and 100GB file transfers its way, the P5 heated up and ultimately throttled. The controller measured 94C, while the SMART data reported upwards of 100-103C before the drive finally throttled down to speeds of 200MBps.

      That said, obviously Tom's hardware would test the thermal performance with heavy writes (coz. that's how you test worst case). For normal gaming, it is not a realistic usage pattern (the SSD does a lot more reads and hardly any writes during gaming). However, for a decent PCIe gen 3 class NVMe TLC SSD, you do take write performance into consideration. P5 is better suited for desktop. Thing is, we cannot have everything, fast writes with great thermal performance generally don't go together.

      We generally don't see reviews on thermal performance with mostly reads so you need to decide whether the heavy write throttle is really an issue for you or not.

  • Thanks for this link, but I went for the WD SN850 with heatsink, all up ~$219.
