Crucial BX300 240/480 GB 3D MLC SSD - £79.19 and £121 @ Amazon

Found 25th Oct
A mainstream consumer SSD that actually comes close to or matches the 850 Evo in performance AND price... took long enough!

3D MLC flash with improvements on the MX300s latency issues, and that had TLC - inferior to MLC. Not even the 850 Evo has MLC. This is very much an unusual spec for this segment, hopefully signals the beginning of the end of the flash shortage...

I feel this is a much better value for momey than the 240GB SanDisk SSD Plus deal posted earlier (but still costs less than 850 EVO) as that is firmly a low end SSD with no DRAM cache, with a variable bill of materials, so you don't know what type of flash memory you're getting until you test it!

Not megga price? Need space though as current SSD is almost full, as in 2Gb left!

It's quite a new model, the first from Crucial with the new Micron/Intel MLC flash (I think, happy to be corrected), so for new-ness, 850 EVO class performance AND the context of the current prices, I think the prices 'makes sense'.

The MX300 isn't bad at all for the average PC user though, and might offer better £/GB value for less performance (that you might not even notice), though not checked prices. Horses for courses etc.

Seems like my M500 was a good purchase in 2014.

Guessing that's an MLC drive... Price was probably about the same as now I'm guessing? Supply and demand (mostly supply) in action.... I actually get mine off eBay but of course many would prefer to stay safe and go for new.

Yeah MLC, £83 in May 2014. The current RAM climate is even worse for both DDR3 and DDR4, got 2x8GB Kingston HyperX DDR3 1866 MHz for £50 a year after that.

I have a crucial, toshiba and sandisk SSD drives. I much prefer the Crucial and Toshiba as they have much better build quality. The sandisk feels flimsy and fragile at the sata connector.

Frankly they are all very fast compared to mechanical drives so any speed difference between these is unlikely to be noticed.

This is a good current deal - although I paid less than £90 for 480/500 gb over a year ago.

Agreed, the average user should probably concentrate more on endurance rather than performance (although they sort of go hand in hand), and I imagine 3D MLC drives like these should do very well in that department.

I think by Black Friday-ish time next year prices for brand new across the board will be nearer to what they were in 2015/2016... hopefully sooner though. QLC flash is on the horizon, too...

I've got a Macbook Pro 2012. Have already doubled the Ram and will look to replace the CD Drive with an SSD like this.
Would this be a good choice or better to opt for the 480gb? I know that its user dependent but I've heard that the improved performance is mainly due to the mac not having a CD drive and I have an external anyway.

The 480GB is actually the far better deal of the two, and larger SSDs are generally faster than the smaller ones due to increased parallelism (more flash chips for writing data to at the same time). I suppose I just included the 240GB since it is still good against the other SSDs available.


Not sure I get what you're saying about the lack of a CD drive contributing to better performance? Do you mean a HDD (Hard disk drive)? If you don't already have an SSD it will probably be the biggest upgrade you can make to your Mac, probably more so than the RAM (which is still a very good thing to get more of). Highly recommended if the upgrade is doable.

Does this have encryption like the EVO does? Don't really need another complication.

ok nice one yes I'll go for the 480gb. Re CD drive, someone in IT just told me that once you lose the optic drive it will speed up anyway. Maybe I got that wrong. So installing it is quite straight forward? Some youtube vids on it. Just a philips head screwdriver and the Caddy?

Hmm, can't say I've heard of CD drives reducing performance like that, Google not much help either. I'd imagine it could only have a noticeable impact if it was actually in use anyway...?

Google did show me that upgrading a MacBook pro (at the very least, the older ones) was a lot easier than I'd thought. If you've got YouTube vids for the same model as yours, definitely go for it.

From what I can see online, the SSD controller supports Opal/TCG but Crucial have apparently disabled this on the BX300. I don't have any direct experience with this, so not sure if there's any other possible hardware encryption available (assuming software encryption is not on the table).

Thanks for the reply. I'm not after encryption. I'd prefer to go without. Just takes that to foul up and *pouf* gone.

If I recall correctly from when I upgraded my macbook pro 2012, you'll be better off moving the hard drive into the caddy where the CD drive was and installing the SSD where the hard drive was previously. The CD drive is connected on SATA 2 which is far slower than the SATA 3 connection to the original hard drive. Hope that makes sense.

The equivalnet spec PC that I built in Jan 2016, would cost me ~25% if built today. What happened? Oh yeah...Brexit vote.

imo average users have ZERO need to worry about endurance , as they normally write very little.Endurance is a done deal now unless you are doing full DWPD + .
I cant remember which is better mx or bx, but FYI the mx300 gives 525gb for only 128 , Actually I'd rather have the MX300 as its 10% more space for only £7 extra ...........

The problem with 'cheaper' DRAMless drives like the smaller SanDisk SSD Plus variants is that instead of updating data tables on the (much faster) DRAM cache, it is constantly writing it instead to flash, which over time does have an impact on endurance. MLC could probably take it but wouldn't think so for DRAMless TLC drives. The 480GB SSD Plus apparently does have a DRAM cache.

Definitely agree that for some, the additional storage on the MX300 might/is be the better choice, but this generation the BX is the higher performance drive in most aspects due to having MLC. One thing this drives apparently excels at compared to its competitors is that it mostly retains its performance when almost full, often something that SSDs suffer with (from personal experience) especially in this segment.

So for a boot drive, I'd recommend the BX300 but for additional storage the MX300 is likely better.

Yes it does thank you for advice. So in essence the pro will boot from the SSD. I will now just decide on the slightly cheaper 480gb at £121 which is newer or the 525g at £128. Thank you

Hot_Rod11516 h, 22 m ago

... the Caddy?


You can leave the SuperDrive (DVD) and replace the old drive with a SSD.
If you want to replace the DVD with a SSD then do not buy a cheap caddy.
Ground [ESD] yourself properly before any work.

Yes you will want to reinstall macOS on your SSD, the increase in boot speed is great. I normally use the SSD for boot drive and the majority of applications, then HDD for large file storage, music films etc as they don’t get much of a boost from being on an SSD.

Thanks for posting op.

One can also order the BX300 240GB from Crucial for the same price with 3 - 5 days free delivery. There's potential for 3% Quidco too.
Hope this helps someone.

Absolutely ridiculous pricing, just buy a used SSD especially if you are only only planning for gaming, I bought a brand new 1TB ssd from sandisk for £150 last year, I would wait for Black Friday or some Christmas deals maybe

I personally use eBay for SSDs but many, many consumers prefer to go for new with the security of the warranty (and easy returns with Amazon) Demand far outstripping supply, probably until mid 2018, it's been a problem for a while. The 480GB price (or 525GB MX300) are still good in the current market.

Also, I'm not sure I'd buy an SSD just for games unless it really was a super bargain, only certain ones see consistent and noticeable benefits vs a HDD... think this is backed up online. Could pick up a cheap 2TB HDD (very cheap used) for much less.
