SSD SATA Recommendation

[MOBMAT]

I need a recommendation for an internal 2TB SATA SSD.

I'm trying to consolidate all my EGTBs which I currently have on a 256Mb USB3 flash drive. I can't fit the Nav 6 man files on it though, but in total, all the EGTBs I have take up about 1.2TB

I saw this unit on Amazon (cheapest)
Crucial BX500 2TB 3D NAND SATA 2.5-Inch Internal SSD - CT2000BX500SSD1

I don't have much experience with this type of device.
Any recommendations?

Samsung 860 PRO and 860 EVO series are good in my experience. M.2 drives are faster though (Samsung 970 series).

oh, the PCLe devices.
I do have a M.2 port for one of those, though it is directly next to the GPU which I would have to take out to see if an SSD would fit. The speed is very impressive but it appears the 970 series is very expensive (twice as much as a SATA drive).

If you have an M.2 slot in your motherboard it's better to use it than a sata drive. e.g.
Sabrent Rocket Q 2TB NVMe PCIe M.2 2280 Internal SSD High Performance Solid State Drive R/W 3200/2900 MB/s (SB-RKTQ-2TB) for $229 is MUCH MUCH faster than any SATA drive. The "2280" means is 22 mm wide by 80mm long, which is a "standard" size drive and should fit in almost all MB M.2 slots. You can either check your motherboard manual or measure the distance from the connectors to the retaining hole.

If you have a really fast CPU it matters a lot to use the m.2 drives.
My 3970x was definitely bottlenecked by using a 5MB/Sec thumb drive.
The 1 TB thumb drive would saturate at 100% and the NPS rate would go to 10% of the full NPS. Changing to ultra-fast m.2 SSDs I see no slowdown whatsoever and at over 100MB/sec in TB heavy positions, the drive is nowhere close to saturated.
I guess if you have a slower CPU you can buy a cheaper drive and it will not matter much.

If you have ATX (not laptop) PCI-E to NVME adapter cost $3 and you do not have to invest in outdated technologies


PCI-E 3.0 x4 SSD are about 5x faster (seq read) than SATA-III

2TB Intel 660P (SSDPEKNW020T8X1) is about +15% in price to Crucial SATA.
It has 1800/1800 MB/sec linear speeds and 220 000 IOPS (Crucial = 95 000 IOPS)

Samsung 970 is much more expensive, but much faster: linear speeds are 3500/3300 and 560 000 IOPS

I've seen my M.2 PCIe Ver.4 drive sustain 3.5Gb/sec for many minutes as a result of massive TB requests by the CPU. The drive is rated at 750,000 IOPS and 5Gb/sec. Even at this very fast pace it slows the NPS down by about 30% or so (90Mnps reduced to 60Mnps with heavy TB requests). The disk que was between 3 and 10 requests long (mostly around 5). In order to have as little effect as possible a 3 or 4 drive raid array with 10-15Gb/sec and ~3,000,000 IOPS sustained is likely needed. This is my next upgrade!

Does it really exist such kind of controller? Which interface bus will it use?
