Crucial Readies the BX300 Mainstream SSD
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.

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.
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.

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

TLC is still TLC... I avoid it as I can.I will better think of my ex then.
Staying ignorant is the best way to ensure that you can continue to make ignorant comments. :D
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 megsper 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.
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.
:toast:
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).
