Having a bit a tough time deciding on best way of adding 1TB of extra SSD capacity to my workstation, I'm more focussed on read performance than writes, currently have 3 free M.2 Slots and a single spare U.2 port, + 4 free SATA ports. Have created the lists below (each list in order of expected perf) and I've striken off the stuff thats over budget, looking at the list, the SATA choices dont make a lot of sense compared to the perf of the NVME stuff, so am currently leaning toward getting a pair of 500GB 960 Evo's or SM961's and striping them (have already got a pair of 250GB striped 960 Evo's and they work quite well for the cost) SATA 1. || 2 x 512GB 860 Pro (£210) = £420 2. || 2 x 500GB 860 Evo (£140) = £280 3. || 1 x 1TB 860 Pro (£450) = £450 4. || 1 x 1TB 850 Pro (£390) = £390 5. || 1 x 1TB 860 Evo (£260) = £260 NVME - M.2 1. || 2 x 500GB 970 Evo (239) = £478 2. || 2 x 512GB 960 Pro (250) = £500 3. || 2 x 500GB 960 Evo (200) = £400 4. || 2 x 512GB SM961 (200) = £400 5. || 2 x 512GB PM961 (189) = £378 6. || 1 x 1 TB 960 Evo (349) = £349 7. || 1 x 1 TB PM961 (379) = £379 But then I've gone and found the 1TB Intel P4510 for just under budget with the following specs and wondering if it would be a better choice, slightly lower read spead than a single 960 Evo, much lower write speed - but should still be high enough for my needs, and it has a simply awesome figure for read IOPS - almost into intel 900p territory... Intel P4510 Performance Solid-state drive capacity = 1000 GB Solid-state drive interface = PCIEx4 (U.2) NVME 3.1 Read speed = 2850 MB/s Write speed = 1100 MB/s Memory type = 3D TLC Random read (100% span) = 465000 IOPS Random write (100% span) = 70000 IOPS Latency (read) 110 = µs Latency (write) 60 = µs TBW rating = 1920 MTBF = 2000000 h Anyone got any experiance with these drives or tried them? Are there any other options I should look at? Most of the NVME drives other than Samsung M.2 are either way out of budget - or way under capacity as far as I can tell. I think this would have lower read perf than striped M.2's, but would definetely be more reliable, and from the spec should last a very very long time. I also find the 960 Evo's I've already got to be quite "peaky" in there performance and wondering if the intel would do better at sustained r/w even if if cant hit the headline r/w rate of the samsung drives... arg - thoughts?!
