Crucial Readies the BX300 Mainstream SSD

[btarunr]

Crucial is giving final touches to its next-generation mainstream SATA SSDs, under the BX300 series. A follow-up to its MX300 series, the BX300 series will be launched later this Summer. The drives combine a Marvell-made controller with Micron 3D TLC NAND flash memory, and likely come in capacities of 240 GB, 480 GB, and 960 GB. Crucial will sell these drives only in the 7 mm-thick 2.5-inch form-factor with SATA 6 Gb/s interface, initially. While the company didn't talk about performance, it mentioned that the drives offer "SATA-saturating performance," meaning that at least its sequential reads could be around the 530 MB/s mark (that of the MX300), if not higher. With the BX300, Crucual is launching a new multi-media SSD install tutorial website that's made as simple to understand as possible, so anyone with a screwdriver can replace their HDD with a new SSD.

What is the improvement over MX300 other than a bit of speed?

 

[Readlight]

hwinfo64 is showing on my 750 evo tlc that the remaining life level is droping rapidly from instaling games lots off. I hope ther wil not be write protected drive but on sandisk extreme usb who has mlc life time waranty has still 100% Beter not to by these tlc drives. Becouse they are expensive 80 -100 euro and i can not by another one. Lexsar write protected made by Micron some kind of conection whit Crucial but made by chaina BARUN electronics.

Doesn't seem to be any...
BX uses weaker controllers, iirc and they may use different NAND chips.

Another clueless user giving advice...
PLANAR TLC can be problematic. 3D TLC is at least as good as planar MLC (which is very reliable).
You bought the worst possible drive (which isn't even offered in capacities over 250GB, thus creating another problem) for heavy usage. And now you're blaming the technology for it.

There isn't. It is their cheaper mainstream offering, while MX offerings are more performance oriented.

MX offerings are more performance oriented.

MX is a bad name choice... because of geforce series, bad memories.

Either way... I'll keep out from any TLC based device... they are really awkward working sometimes(really dislike like my EVO 750) and my favorite Cruicial drive was still M550 that really performed really stable across all storage span because of the amount of multiple channels/IC's without any cache mumbo jumbo.

I have a 120GB BX100 and a 240GB BX200, if this is priced right I might get the 480GB model to complete the set.

Considering the prices you could sell those old off as they were cheaper and get this larger one for free.

But then he wouldn't have a set.

Think Logitech MX then

This is 3D NAND, the same stuff Samsung is hawking now. 3d TLC is not the same thing as TLC, which does not normally last as long as MLC. 3-d TLC has them all beat. Don't get confused by the silly naming scheme.

this explains well the difference between planar TLC, or 2d, which is your bad experiences, and 3d TLC.

It doesn't change the fact I somehow manage to screw up the drive while transferring few games from primary drive to backup... ie around 100-150GB's and suddenly it starts to crawl to 50-30MB/s, I did a full format and it helped... still... sammy doesn't do well in budget department... it gimps the product too much, that applies to most consumer electronics they make.

TLC is still TLC... I avoid it as I can.

Think Logitech MX then

I will better think of my ex then.

Really? You're not gonna read the articles provided above?

Why should I? Because I am complaining about my 750 EVO.

That's the spirit!
Staying ignorant is the best way to ensure that you can continue to make ignorant comments.

And you think that drive is the same as completely different drives.

blah blah blah...

Whatever... TLC is TLC... even the older 3D TLC MX300 if gets dirty will start to walk like Long John Silver with a wooden leg dropping to the same 30ish megs per seconds... you expect some sort of magic there? TLC is designed to be like that and using it like a hot transfer backup SSD renders it useless, you need to format it fully each time to regain write speed and it will be a general rule for TLC. Same as with my crapped planar 750 EVO... SLC/MLC or 3D NAND FTW.

 

[rtwjunkie]

Just no. Normally you are really smart about technology, so I'm confused why you are being stubborn.

3D TLC like in the MX 300 and BX 300 as well as recent Samsung cards is not the TLC you are thinking of. They are two different things, and behave differently.

Anyway, no big deal. I'm with you in preferring MLC anyway.

Micron is late to the party... they add more layers, possibility to use less channels on controller for most popular drive densities, cheaper for them most probably not us, principally delivering the same, it will not exclude inherited three bit cell voltage level, it just needs additional time(algo) to make the ready to work again. Situations if you delete a large steam/gog game to make space in your stuffed drive and install a new one will result in no cache and dreadfull slow write speeds. I've linked in my previous post MX300 review and scroll down the tests where are the dirty writes resulting 28.9 MB/s(a common sight)... in books such write performances are no good... i write them off also, thus the attitude.

OK. Thanks for the link and additional reading.

Edit: I see what the problem is. The cache on the MX300, and presumably the BX300 here is old SLC, which got totally overwhelmed (not surprising).
