If you already used all the m.2 slots on the motherboard and wondering what to do witht the 6 Sata sockets… this could be a good option : )

Got 10 for my Pony Slaystation 5, going to be so fast now.
BX is not reliable, MX or Samsung much better.
Any good for storage for a 2nd drive?
Whats the difference between BX and MX?
The difference is like $10 recently might as well get the MX.
MX500 doesn't have quite common anecdotes of BX500 failing well within warranty, sometimes within months of purchase.
MX is usually (but not always anymore) TLC not QLC, and has DRAM.
Even if you got a QLC version; the DRAM ensures the same speed of the drive from zero to about 98% full.
The dramless BX series see's a dramatic dip once beyond about 85-90% full (as it shrinks its dynamic cache) and starts to slow down well before that.
Even if you got a QLC version; the DRAM ensures the same speed of the drive from zero to about 98% full.
That's wishful thinking. No, QLC suffers performance penalty far greater than a DRAM can solve. Furthermore, Micron has started to cut the DRAM size on 2TB and 4TB version of MX500.
1TB or below QLC SSDs are even more annoying, and for SATA space, we are looking at controllers often with even fewer channels, which adds insult to injury.
BX500 is inferior no doubt because even if you get the TLC version, it is inferior grade TLC.
@netsurfer: Wishful, yet proven.
The managment of DRAM to SLC is impressive on the latest MX firmware.
The fact that it's only required to reach somewhat SATA speeds seems to be the saving grace; because it's sure not maxing out the interface.I'm not about to erase my drives to test again; but I saw no notable performance drop doing a fill test until it pushed the last few %.
I guess YMMV, but mine was a smooth ride.
We know there's a mix of chips and controllers appearing, so I likely got a golden sample based on your experience with it compared to mine.@MasterScythe: It's not the DRAM (1GB normally, if you are lucky you get the 2GB for the 2TB version, from memory Crucial is doing 512MB max DRAM in newer batches of large size MX500s). The main use of the DRAM is to store the location of the files (where they are stored in the flash cells). MX500's TLC cells are decent enough so it is known to not doing aggressive SLC cache. The last few % is the foldback write so there will be a drop.
QLC SSDs have to use very aggressive SLC cache and the foldback write kicks in quite early. There is no free lunch for QLC (it is 4-bits per cell) so even if you factor in best case spare cells, it is at best 33% dynamic SLC cache when empty. The write back penalty kicks in on or before 33% (as the SLC has taken up close to all the cells).
I have an SSD with Micron QLC NAND chips. It's SATA3 based as well and it is terrible at QLC native write speed. Foldback write penalty for QLC is ugly. If 1GB DDR3 or DDR4 DRAM chip can make a QLC SSD runs at fast as TLC, don't you think SSD makers would utilise that everywhere?
NV2 (el cheapo DRAMless NVMe) 1TB's TLC native write speed is 600MB/s (SLC cache write speed is 2.7GB/s). We get these expensive SATA SSDs because we don't have that many m.2 slots.
these prices will cause the extinction of 1TB HDDs
I don't think I've even seen anything below 4tb posted here (for HDDs).
I meant eliminated from the market entirely
not until 1TB SSD's get to about $30. 1TB keep selling for about $15-20 on FB & Scumtree.
it's about time
You might not be able to use all your sata ports if you have filled all your m2 slots - might want to check that.
Solid point - the overlap of the chipset can mean you can only use some ports to the exclusion of others
This usually (but not exclusively) happens when one of your M.2 slots is a sata port.
Its not unheard of, but very uncommon for a whole sata controller to share a lane with an m.2 slot.
perfect for a last gen console upgrade
