Probably not the right community for this, but I’ve been searching for a new 2TB SSD for my Thinkpad T14 G1, It’s only PCIe gen 3.0, so both are going to be limited by that anyway. I specifically need resonably fast sustained write speeds, and both of these can write at >1GB/s for 15 minutes. The Samsung seems to be the better choice, but I remember them having some data loss issues a while back and that is worrying me, and the P510 is quite new, so not much time for any issues to be found. I can get both of them for the exact same price, which of these is the better pick? The P510 also seems to use a bit more power, so maybe not a good idea for a laptop?
EDIT: Thanks for the help, ended up getting the Samsung 990 pro
The Samsung has DRAM-cache. Better performance on write speeds and less wear.
Between those two devices, get the Samsung, after you get it installed just run their Magician software and make sure it’s on the latest firmware and you’ll be fine on that data issue.
Thanks, ended up getting the Samsung
I agree
FWIW the only metric that really matters is 4k random io without queue depth. If it’s anywhere near what the modern drives offer it’ll be fine regardless of pcie generation.
Doesn’t matter one bit if you’re running a 14000MB/s drive vs a 500MB/s drive. The 4k io is sitting under 200MB/s for all nvme options I know of in the consumer world.
How is that? I need good >250MB/s sustained synchronous transfer for saving real time sample data, does the random 4k io still impact that?
I suppose it depends on your data size. If it is small data at very high speed yes it will be close to 4k random. If it is big files, probably not.
If saving speed is that important maybe think about compressing data. The other solution would be to have a second SSD and write on both simultaneously
I’m need to save high speed radio samples, think a single super high speed ~100MHz audio wav recording, so not really compressible and can use large block IO. Thankfully it’s about as close to a synthetic write test as you could get. I ended up getting the Samsung
On a gen 1 t14 what you pick is irrelevant. Get the cheapest thing possible.
I normally would get a cheap P3+, but those SSDs have terrible sustained write performance, I needed the sustained speed here, ended up getting the samsung
