Samsung 850 PRO SSD Coming Q4

Old 1 Comment on Samsung 850 PRO SSD Coming Q4 71

Introduction

The Samsung 840 PRO and 840 EVO drives have been the pinnacle of 2.5″ SSD drives for over a year now. The drives have been commercially successful, ans Samsung is announcing the successor to the high end 840 PRO drives, the 850 PRO.

Specs

Specs anhd a preliminary review of the new drive have leaked on StorageReview.com, showing it to be a top performer. The drive boasts Samsung’s new V-NAND tehcnology, which stacks NAND vertically, instead of relying on more and more layers of cells. This technology effectively increases the life of the drive, and Samsung is now offering a 10-year warranty and is rating the drive for up to 150 terabytes of writes. Considering that in testing, the 840 PRO reached over a petabyte of writes, we can assume the 850 will have even greater endurance and that this is a conservative estimate from Samsung.  The Storage Review article lists the following specs:

Samsung SSD 850 PRO specifications:

  • Capacities:
    • 128GB (MZ-7KE128BW)
    • 256GB (MZ-7KE256BW)
    • 512GB (MZ-7KE512BW)
    • 1TB (MZ-7KE1T0BW)
  • Interface: Serial ATA 6Gb/s (compatible with SATA 3Gb/s and SATA 1.5Gb/s)
  • Form Factor: 2.5”
  • NAND Flash Memory: Samsung 32 layer 3D V-NAND
    • DRAM Cache Memory:
    • 256MB (128GB)
    • 512MB (256GB & 512GB)
    • 1GB (1TB) LPDDR2
  • Claimed Performance
    • Sequential Read: Up to 550MB/s
    • Sequential Write: Up to 520MB/s
    • Random Read (4KB, QD32):
    • Max. 100,000 IOPS
    • Reliability: 2,000,000 hours Mean Time Between Failures (MTBF)
    • TBW: 150TBW (30,000 P/E Cycles)
  • Power Consumption:
    • Active Read/Write (Average): 3.3Watt/3.0Watt (1TB)
    • Idle: 0.4Watt
    • Device Sleep: 2mW
  • Temperature:
    • Operating: 0°C to 70°C
    • Non-Operating: -40°C to 85°C
    • Humidity: 5% to 95%, non-condensing
  • Vibration: Non-Operating, 20~2000Hz, 20G
  • Shock: Non-Operating,1500G, duration 0.5m sec, 3 axis
  • Dimensions (LxWxH): (100.00±0.25) x (69.85±0.25) x (6.80±0.20) mm
  • Weight Max: 66g (1TB)
  • Warranty: 10-year

According to the review, even the early prototype they received trumps the old 840 PROs, EVOs, and every other major manufacture’s top performers.  Expect this to be the best performing 2.5″ SATA III SSD for some time to come, as it completely saturates the bus.  Keep in mind, however, within the next year or two SATA Express drives and M.2 PCI-E drives will start flooding in, dominating any SATA III drive, without much markup. The SSD wars are heating up, and it looks like Samsung had an Ace in its hand.

    It is interesting that the 840 EVO Pros have capacities of 128, GB, 256GB, 512GB, etc while the regular (consumer grade) 840 EVOs have capacities of 120GB, 250GB, 500G, etc. I have personally tested the consumer grade EVOs and find them lacking in performance for my 4k Blackmagic design cameras! Alternatively I have used SSDs by OWC such as the 240GB Mercury Pro 6G and find the performance to be fantastic in a 2010 Mac Pro. I will definitely I will need to try the 840 EVO Pros so see how they stack up against the drives from OWC!
