This one or SN570 for the OS
You won't see any real performance difference.
Unless you're writing a lot of data. The SN570 500GB has a tiny 13GB of pSLC cache and once exhausted the speed drops down to 615MB/s. The P34A60 512GB has dynamic pSLC cache and after writing 67GB it fell down to a whopping 140MB/s. That's really slow!
I'd go for the SN570 personally.
When you say after writing 67GB it drops, is that test done with say a 100GB file transfer or something?
I'm struggling with where this would impact a single real world scenario?
(surely even 100GB+ games are broken down into many smaller files, and usually downloaded at a much much slower rate than even a choked ssd)
@Grish: Keep in mind the 67GB is dynamic, based on the existing free space. The drive is TLC, so the maximum possible dynamic SLC cache is 1/3 of the empty drive.
For example at 80% fill, the max SLC size possible is 34GB.
The actual answer is something like we don't know how the SLC cache size changes as the drive is filled (except that logically it must get smaller). If the drive maintains a 67GB cache until it's 60% filled, that would be fairly decent. If the drive keeps the same proportion of cache as an empty drive (e.g. 26GB cache at 60% filled), that would be quite bad given the terrible native write speed.
Probably pick up 1TB SN570 $75 after cashback.
SN570, it has the much newer controller which does perform well in PCIe gen 3 x4. Much newer type of NAND chips also.
You would only get this one if it is for a really old PC where you don't intend to do anything important on it (i.e. if the SSD went !@#!@#@ later on, you are not going to sweat about it). Basically, for a device that isn't really worth upgrading, but a dirt cheap SSD upgrade will still make a big difference (i.e. it currently uses a traditional HDD).
i had two of 1TB SP P34A60 in my NAS
they both died within the month of ownership.
with about 11TBW of life consumed and SMART reporting about 92% life left.
meanwhile, my spare Samsung 870 (i think its 870 evo) that's quite a few years old, is still fine, after 18TBW with 100% of life left
now i have the samsung and a wd blue 1tb (which is up to 8tbw) and still okay for now.
Other than $1 is there any difference performance wise between the SP 512GB and the Teams 512GB (https://www.ozbargain.com.au/node/755391)?
Both are el cheapo SSDs which rely on SLC cache to cheat in writes. SP is a little bit faster, but not by much. SP uses Intel NAND (older ones though) whereas Team uses Micron NAND. Both are cheap grade NANDs. The real TLC NAND performance is kinda like in BX500 class (not that bad, but not much better either).
Depends if it has an NVMe slot.
I can't believe how cheap SSDs are now. Does this one have DRAM or is it just not happening in this price bracket?
DRAMless, dated / old SSDs.
Acceptable to use two of these in a Synology Nas?
afaik synology only uses them for cache, so .. maybe ok.
i had two die in my qnap.
so .. no.
