Crucial P3 for storage/backups?

wheresmycar · Dec 17, 2022

Hi,

I've been keeping an eye on 4TB SSD prices and the Crucial P3 looks tasty @ £251

Is the P3 a decent option for secondary storage? It's mostly for backups.... differential backups on a weekly basis and Full Backups every 2 months + phone/online cloud media backups. I've already got a fast system NVME for the primary drive and on top i don't fancy using spinners for secondary storage regardless of cost-effectiveness.

yeah of course.

Where are you getting a WD AN1500 for $336? That is a $1500 drive where I live.

i can not recommend this SSD at all...
it's extremely bad QLC trash that tanks down to two digit writing speeds (like an old samsung QVO drive where backing up another drive takes two hours instead of 10 minutes for 50 bucks more)

I didn't notice. Its showing on Amazon for £336 but seems like a listing error. The 2TB variant is going for around the same price (minus discount) hence defo a cock-up by a drunk employee high on "can't be bothered with this job" hehe

What am i looking at... how long would lets say a full back of 1TB take? How does it compare to SATA, something like a Crucial MX500 and Samsung 850 EVO (i currently own a few of these 500GB~2TBs)

Also which would you recommend? I don't mind stretching the budget although i was hoping some discount action with Xmas sales in the ~£250 region

Tomshardware P3 review says 100 MB per second for sustained sequential write (which is what a 1 TB backup would be) for the 1 or 2 (can't remember) TB version. A TLC drive such as the MX500 would be considerably faster than that. If you are looking at large 2.5" SATA drives then you may want to consider the SanDisk Ultra 3D 4 TB (which TPU has reviewed).

What about the P3 plus it is running on a faster interface. should be at least 3 GB/s sequential.

If you are willing if they honour it I will be more than happy to pay for it and shipping.

3 GB per second until the pSLC cache runs out, after that it is 100 MB (maybe 200 MB for a 4 TB model) per second, which doesn't even max out SATA II, let alone SATA III or PCIe 3.0/4.0-based NVMe

OP is going to have to decide whether 100 MB per second is acceptable to them for a backup drive or not. That is what it boils down to ultimately. I disagree with calling the P3 "trash" but at the same time a drive like this is clearly not for everyone and you get what you pay for.

It should be noted that while this is true, if it is only used for backups then differential backups wont likely run into this bottleneck after the first backup.

yes, it actually occurred to me this afternoon to bring up rsync and delta backups but I forgot to for some reason. That said, we don't know what kind of backups OP is making. If these are weekly (rotating) backups of huge files than delta backups may not make much of a or any difference.

I can but on the condition the payment is received first. My fear is this seller might not deliver. I checked his feedback comments and theres quite a few with used items sold as new, faulty items and non-delivery complaints which look recent. On top, i've viewed the sellers listings and oddly enough all of his available products are either 10 or 15 units remaining in stock... which is strange.

The seller is also based in the UK and lists this item as dispatched from the UK but delivery is set to 7-13th Jan (almost 4 weeks). Then again, there's a bunch of 5 star reviews too...

I suggest you check his credentials/activity yourself before considering green lighting the purchase: (UK seller) https://www.amazon.co.uk/WD_BLACK-AN1500-Card-6500MB-4100MB/dp/B08HBZCSHW/ref=sr_1_5?crid=2XW5F4BD84B4Z&keywords=an1500&qid=1671387700&s=computers&sprefix=an1500,computers,65&sr=1-5

Is an SSD really suited for backup?

a cost effective solution, no.

A preference over the clickity click spinner, yes. Added bonus, occasionally I'm shifting large files over to the HD from my x3-x4 fast NVME... the HD bottleneck always comes to mind.

I was worried about long term archiving which is why I suggested an M-disk system, but that suggestion was labelled as low quality post, so I deleted it.

Archiving is something completely different from backup.
