\nWhy you can trust Tom’s Hardware<\/p>\n <\/span> The good news is that Sandisk is still putting out SSDs for consumers, and these are not just cheap replacements. The Optimus GX Pro 850P is a bona fide high-end Gen 4 SSD that puts Sandisk\u2019s name on the WD Black SN850X\u2019s legendary design. This means DRAM, TLC flash, and good performance for any role.<\/p>\n Like the Black SN850P, which is a Black SN850X made with a heatsink and for the PS5, the 850P is made for the console. Its heatsink is excellent, and it would fit right into your desktop PC, too. We wouldn\u2019t recommend shucking it for use in a laptop, but theoretically it could work there as well. Our main concern would be the pricing, which is a bit steep \u2013 this is a nice drive, but you\u2019ll pay a premium for it.<\/p>\n Swipe to scroll horizontally<\/p>\n Product<\/p>\n 1TB<\/p>\n 2TB<\/p>\n 4TB<\/p>\n 8TB<\/p>\n Pricing<\/p>\n $309.99 <\/p>\n $609.99 <\/p>\n $1,139.99 <\/p>\n $2,249.99 <\/p>\n Form Factor<\/p>\n M.2 2280-S3-M (PS heatsink)<\/p>\n M.2 2280-S3-M (PS heatsink)<\/p>\n M.2 2280-D5-M (PS heatsink)<\/p>\n M.2 2280-D5-M (PS heatsink)<\/p>\n Interface \/ Protocol<\/p>\n PCIe 4.0 x4 \/ NVMe 1.4<\/p>\n PCIe 4.0 x4 \/ NVMe 1.4<\/p>\n PCIe 4.0 x4 \/ NVMe 1.4<\/p>\n PCIe 4.0 x4 \/ NVMe 1.4<\/p>\n Controller<\/p>\n Sandisk Proprietary<\/p>\n Sandisk Proprietary<\/p>\n Sandisk Proprietary<\/p>\n Sandisk Proprietary<\/p>\n DRAM<\/p>\n Yes<\/p>\n Yes<\/p>\n Yes<\/p>\n Yes<\/p>\n Memory<\/p>\n Sandisk TLC 3D NAND<\/p>\n Sandisk TLC 3D NAND<\/p>\n Sandisk TLC 3D NAND<\/p>\n Sandisk TLC 3D NAND<\/p>\n Sequential Read<\/p>\n 7,300 MB\/s<\/p>\n 7,300 MB\/s<\/p>\n 7,300 MB\/s<\/p>\n 7,200 MB\/s<\/p>\n Sequential Write<\/p>\n 6,300 MB\/s<\/p>\n 6,600 MB\/s<\/p>\n 6,600 MB\/s<\/p>\n 6,600 MB\/s<\/p>\n Random Read<\/p>\n 800K<\/p>\n 1,200K<\/p>\n 1,200K<\/p>\n 1,200K<\/p>\n Random Write<\/p>\n 1,100K<\/p>\n 1,100K<\/p>\n 1,100K<\/p>\n 1,200K<\/p>\n Security<\/p>\n TCG Opal v2.01<\/p>\n TCG Opal v2.01<\/p>\n TCG Opal v2.01<\/p>\n TCG Opal v2.01<\/p>\n Endurance (TBW)<\/p>\n 600TB<\/p>\n 1,200TB<\/p>\n 2,400TB<\/p>\n 4,800TB<\/p>\n Part Number<\/p>\n SDSG81100TAH-000E0<\/p>\n SDSG81200TAH-000E0<\/p>\n SDSG81400TAH-000E0<\/p>\n SDSG81800TAH-000E0<\/p>\n Height<\/p>\n 9.89 mm (w\/ HS)<\/p>\n 9.89 mm (w\/ HS)<\/p>\n 10.31 mm (w\/ HS)<\/p>\n 10.31 mm (w\/ HS)<\/p>\n Warranty<\/p>\n 5-Year<\/p>\n 5-Year<\/p>\n 5-Year<\/p>\n 5-Year<\/p>\n Today’s best Sandisk Optimus GX Pro 850P 2TB SSD deals<\/p>\n The Sandisk Optimus GX Pro 850P is available at the same capacities as its WD Black SN850P forebear: 1TB, 2TB, 4TB, and 8TB. This also matches the original WD Black SN850X and its later 8TB SKU. Prices at the time of review for the Optimus GX Pro 850P are $309.99, $609.99, $1,139.99, and $2,249.99. These prices are well above the $234.99, $494.99, and $1,019.00 that the Black SN850P is currently demanding. We think the prices will come down on the Sandisk drive, but be aware of the comparable alternatives when making a purchase.<\/p>\n Latest Videos From<\/span>Tom’s Hardware<\/span><\/span><\/p>\n The drive can reach up to 7,300 \/ 6,600 MB\/s for sequential reads and writes and up to 1.2 million random read\/write IOPS. This performance is at the top for a Gen 4 drive and, frankly, is capable of delivering an excellent experience even for heavier workloads. The drive\u2019s warranty is standard at five years with 600TB of writes for every TB of capacity. The Optimus GX Pro 850P supports data-at-rest encryption through TCG Opal v2.01, but this is not explicitly listed for the SN850P, likely as this model is designed for use in the PS5.<\/p>\n Sandisk fully supports its drives with downloadable software. For the Optimus GX Pro 850P this includes the Sandisk Dashboard, which is Sandisk\u2019s version of WD\u2019s Dashboard, and Acronis True Image for Sandisk. The former is an SSD toolbox with all of the expected features: drive health and SMART monitoring, firmware updating, performance testing, etc. Acronis True Image is OEM-licensed software used for backing up files and imaging drives.<\/p>\n \n
