SSD-uri NVMe in Moldova: Samsung 9100 PRO PCIe 5.0, 990 PRO Gen4, Crucial T705

9100 PRO 4TB Gen5 (20 790 MDL): sequential read 14.8 GB/s, write 13.4 GB/s, IOPS 2.2M/2.6M random read/write, controller V-NAND 8th gen TLC, target enthusiast cu workflow 8K video plus gaming AAA cu DirectStorage native. 990 PRO 4TB Gen4 cu Heatsink (19 499 MDL): sequential read 7.45 GB/s, write 6.9 GB/s, IOPS 1.6M/1.55M, controller V-NAND 7th gen, target mainstream gaming AAA plus creator 4K. Real-world workload: Adobe Premiere 4K timeline scrubbing fluid pe both, 8K timeline export 9100 PRO completes in 8 min vs 990 PRO in 13 min (38% faster). Cyberpunk 2077 load time: 9100 PRO 8.2s vs 990 PRO 9.4s (1.2s faster, imperceptibil pentru utilizator typical). Pentru creator video 8K sustained: 9100 PRO clear (38% timeline export speedup). Pentru gaming AAA primary + 4K video edit casual: 990 PRO sweet-spot value (saving 1 500 MDL pentru 95% workflow identical perception).

Samsung 870 QVO 8TB SATA (31 190 MDL, 3.9 MDL/GB): 2.5 inch SATA SSD cu sequential read 560 MB/s, write 530 MB/s, QLC NAND 4-bit. Connection SATA III 6 Gbps max via motherboard SATA port. Target: secondary storage Plex media library, game library Steam, photo/video archive cold storage. 4x Samsung 990 PRO 2TB NVMe Gen4 (4x ~8 500 MDL = 34 000 MDL total, 4.25 MDL/GB): NVMe Gen4 cu sequential read 7.45 GB/s per drive (12x mai rapid vs SATA QVO). Connection M.2 PCIe 4.0 x4 (necesita motherboard cu 4 sloturi M.2, X670E plus Z890 premium). 870 QVO castiga pe: pret cu 9% mai mic per GB (3.9 vs 4.25 MDL/GB), single drive simple management plus zero motherboard slot limitation, capacity 8TB single unit. 4x NVMe castiga pe: throughput 12x mai mare (random read parallel 4 drives), redundancy RAID acceptable (RAID0 stripe = 2x performance, RAID5 = 1 drive fail safe). Pentru bulk media library cu prioritate cost: 870 QVO 8TB clear. Pentru workstation render cu RAID0 scratch disk sustained: 4x NVMe Gen4.

Kingston XS2000 4TB (18 149 MDL): USB-C 3.2 Gen2x2 20 Gbps, sequential read/write 2000/2000 MB/s sustained, dimensiuni 69.5x32.6x13.5mm 28.9g weight (cea mai mica plus usoara SSD external 4TB pe piata), IP55 splash resistant. Samsung T9 4TB (estimat 12 000-15 000 MDL tier): USB-C 3.2 Gen2x2 20 Gbps similar, 2000 MB/s read/write sustained, dimensiuni 88x60x14mm 122g weight, IP65 dust+water resistant superior, password protection AES 256-bit hardware encryption. Kingston castiga pe: pret similar tier dar form-factor cel mai mic plus usor portable extreme, build aluminum solid premium. Samsung castiga pe: IP65 vs IP55 (mai bun pentru travel outdoor harsh conditions), hardware encryption AES 256 pentru data security (Kingston software-only). Pentru creator travel cu prioritate footprint minim plus weight: Kingston XS2000 clear. Pentru data sensitive plus rugged outdoor (camera RED CFexpress backup field): Samsung T9. Pentru utilizator standard backup laptop monthly: ambele acceptable, alege pe pret disponibil.

PCIe Gen5 M.2 slot: necesita motherboard chipset cu PCIe 5.0 lanes routed la M.2 socket dedicat. AM5 chipsets: X670E plus X670 mainstream toate au PCIe 5.0 M.2 dedicated (lane allocation rezerva PCIe 5.0 x4 pentru slot M.2 primary). B650E (entry-Extreme) suporta PCIe 5.0 M.2. B650 mid-mainstream NU suporta PCIe 5.0 M.2 (doar PCIe 4.0 max). LGA1851 chipsets: Z890 toate PCIe 5.0 M.2 suport. B860 mid: PCIe 5.0 M.2 suport partial (verify motherboard specific spec). LGA1700 legacy: Z690/Z790 high-end PCIe 5.0 M.2 dedicated single slot. B660/B760: PCIe 4.0 max. Pentru utilizator cu Samsung 9100 PRO Gen5 SSD: motherboard X670E sau Z890 mandatory pentru utilize Gen5 speed. Pentru B650 mid-tier cu Gen5 SSD instalat: SSD ruleaza in compatibility mode PCIe Gen4 speed (max 7.5 GB/s, pierde 50% throughput Gen5). Pentru build budget cu B650/B760: NU justifica Gen5 SSD purchase, alege Gen4 990 PRO/SN850X.

TBW (Total Bytes Written) rating: total amount of data written to SSD lifetime under warranty. Samsung 990 PRO 4TB: 2.4 PB TBW. Samsung 9100 PRO 4TB: 2.4 PB TBW. Calculation real-world workload: utilizator gamer mainstream scrie ~20-50 GB/zi (game install 50-150GB plus updates 5-20GB plus saves plus cache browser). Sustained 50 GB/zi = 18.25 TB/an = 109.5 ani pentru atinge 2 PB. Practical: 95% utilizatori NU vor atinge TBW limit in 5-10 ani sustained utilizare. Edge cases unde TBW relevant: creator video sustained editing scratch disk on-SSD daily (200-500 GB/zi write workload), Steam game library cu reinstall frecvent (200+ games totala 5+ TB write per cycle), virtualizare Docker cu image rebuild daily. Pentru workload extreme creator video sustained 500 GB/zi: 2 PB TBW = 4000 zile = 11 ani (acceptable). Pentru utilizator standard: TBW limit irrelevant practical. Pentru workstation server 24/7 enterprise: utilize Samsung PM1735 enterprise tier (17.52 PB TBW = 8x consumer).
