SSD Review: 850 EVO Versus 850 PRO
For the past decade we’ve been hearing people say that it was only a matter of time before Solid State Drives (SSD will nearly completely kill off magnetic drives. Traditional hard drives will still exist in niche markets they said, but SSDs will eventually reign supreme with regards to performance, cost, form factor size and capacity. Any PC enthusiast that has built a system in recent years knows that SSDs have already won the performance and form factor battle, but they are still lacking in storage capacity and cost. The $/GB argument is very subjective, but it appears that many are wanting to purchase flagship SSDs wellbelow the $0.50 mark when it comes to cost per GB.
Samsung has raised the bar with regards to storage capacity in its SSDs todayby releasing massive new2TB models in the 850 PRO and 850 EVO product lines. These areSamsung’s highest capacity SSDs to datefor the consumer market and they are being released now because Samsung feels the market and pricing will finally support large 2TB SSDs. Samsung’s previous highest capacity SSD could hold just 1TB of data, so Samsung has doubled the storage capacity of their consumer SSD product line!
Both of the 2TB drives are also priced below $0.50 per GB!
These drives are just a capacity increase for the existing Samsung 850 PRO and 850 EVO series, so there isn too much new to talk aboutunder the hood as the amount of NAND is the only thing of significance to change. We already did reviews on the Samsung 850 Pro 1TBand Samsung 850 EVO 120GB and 500GBdrives when those series first were launched, so we let you go back and read those if you like all the background information on each series.
Both drives useSamsung’s newest MHX controller along with the latest 3D V NAND technology, in which storage chips are placed on top of each other. By utilizing 3D V NAND you can get up to 50% power savings over 2D planar NANDand do so in a smaller package! The Samsung 3D V NAND is stacked 32 cell layers vertically over one another and thestorage chips are connected through a thin, high speed connector called TSV (Thru Silicon Via). This is one of the reasons for the cost and warranty difference between the 850 Pro and 850 EVO as the 850 Pro is using what many would argue is better NAND. Many will say that 2 bit MLC NAND far exceeds the needs for consumer SSDs,
but we had our fair share of SSDs die here over the years and weare big fans ofendurance and reliabilityafter having numerous failures.
When it comes to performance the 850 EVO 2TBSSD’s sequential read speed is 540 MB/s and write speed is 520 MB/s, according to Samsung’s measurements. The random read speed of the drive is 98,000 IOPS and the write speed is 90,000 IOPS. The Samsung SSD 850 PRO is able to slightly best those numbers with 550 MB/s read and 420MB/s write sequential side of things and 100,000 IOPS read and 90,000 IOPS write with regards to 4K Random performance at a Que Depth of 32. The performance numbers are super close on the 850 Pro and 850 EVO, so the key differentiation factors between these two drives would be the endurance and the pricing. Both drives even offer AES 256 bit Full Disk Encryption (FDE),
TCG/Opal V2.1 and eDrive security support
When it comes to pricing the Samsung 850 series is the number one selling line of SSDs right now and one of the reasons is that the pricing on the Samsung 850 EVO is pretty spectacular. You are looking at just $0.32 per GB on the 500GB model and that the 480 512GB capacity range is very popular withgamers and enthusiastsright now as you can hold a decent number ammount of information on a boot drive of that size. The Samsung SSD 850 EVO 2TB drive that has a suggested retail price of $799.99 ($0.39 per GB) and the Samsung SSD 850 Pro 2TB drive is slightly higher at $999.99 ($0.48 per GB). Samsung is charging 25% more for the Samsung 850 Pro and that higher price is based primarily on theendurance difference.
