SSD Ranking: The Fastest Solid State Drives

Want to remove the speed limit on your PC? How about revving up the transfers and reads on your servers? Here’s the list of the fastest SSDs around at the time of writing.This list is not attempting to be the final word on SSD performance – just a rough guide to NAND Flash-based storage. It is primarily based on sequential read and write speeds (ideal circumstances); keep in mind that there are several other factors that should be taken into consideration when choosing a solid state drive, not least reliability. To put it simply, an SSD’s life span is determined by the number of times each block can be written to before it wears out. SLC (Single-Level Cell) NAND is more durable than MLC (Multi-Level Cell), which in turn is more durable than TLC (Triple-Level Cell) NAND. On top of which an older (e.g. 34nm) production process is more durable than a newer (e.g. 25nm) process and so on. For the average home or office user this is not really an issue though, since any MLC-based drive will still last for years and likely outlive the rest of an average home or office computer by a wide margin. But don’t rely on affordable drives with cheap NAND in a server, or any other environment with a continuous, high workload and similarly high reliability requirements.

Consumer Drives (2.5-inch SATA, 6 Gbps)

1. Samsung 850 Pro

Available Capacities: 128GB – 1TB
Interface: SATA III 6Gbps
550MB/s read (256GB)
520MB/s write (256GB)

Samsung’s biggest strength in the SSD segment so far has been reliability–many have opted for Samsung drives mainly on account of their hassle-free operation. Unlike many other known brands that rely on third-party components, including NAND modules as well as the even more important controller, Samsung uses its own hardware throughout. The 850 Pro series uses its own MEX controller in combination with state-of-the-art 3D NAND (V-NAND), which increases density without compromising on performance. Indeed, the 850 Pro series is consistently ahead of the competition in most areas, so you will have to move away from the SATA interface to see better performance.

2. SanDisk Extreme Pro

Available Capacities: 240GB – 960GB
Interface: SATA 3 6Gbps
550MB/s read
520MB/s write

SanDisk’s Extreme Pro is a direct successor to the Extreme II (see below). Just like its predecessor the drive lives up to the expectations implied in the model name. It is slightly ahead of the Extreme II in most areas with sequential read speeds of 550 MB/s and write speeds of 520 MB/s (4K random read/write 100K/90K IOPS), although you will hardly notice the difference in everyday tasks.

More importantly though, SanDisk is confident enough to offer a 10-year warranty with the Extreme Pro – a unique offer in the consumer (or prosumer) segment. The 19nm MLC NAND is allegedly good for writing 22 GB of data per day for 10 years. Consequently, when this drive finally wears out in the average system built today, the SATA interface will be long since obsolete. The Extreme Pro is rather old by now, but then again so is the SATA interface and the drive should definitely be on your short list when evaluating high-end SATA 6 Gbps drives.

3. Mushkin Striker

Available Capacities: 240GB – 960GB
565MB/s read
550MB/s write

Mushkin is one of the few companies that does everything in-house in the US, from design to engineering to testing. The drive uses the Phison PS-3110-S10 controller and a Micron 16nm MLC NAND. The Striker is rated at sequential speeds of up to 565MB/s (read) and 550MB/s (write). 4KB random reads for the drive is 88K IOPS and the 4KB random write is 91K IOPS.

The drive features TRIM support, SmartECC for error correction, SmartRefresh for fixing weak storage blocks, and SmartFlush to safeguard against power loss. Unfortunately it “only” comes with a 3-year warranty, which might be somewhat discouraging for professional users.

4. Corsair Neutron XT

Available Capacities: 240GB – 960GB
560MB/s read
540MB/s write

Corsair has long been a crowd favorite when it comes to fast drives. This gamer-focused drive promises better reliability, being backed by a 5 year warranty and SmartECC for fixing ECC failures.

The Neutron XT uses a Phison PS3110-S10 controller and high quality Toshiba 19nm MLC NAND. The 4KB random read goes up to 100K IOPS and the 4KB random write goes up to 90K IOPS. Corsair offers a 5-year warranty on the drive. It also support SmartECC, SmartRefresh, SmartFlush, and end-to-end data path protection.

5. Transcend SSD370

Available Capacities: 120GB – 480GB
Interface: SATA 3 6GBps
560MB/s read (256GB and up)
460MB/s write (512GB and up)

The SSD370 uses a Transcend TS6500 controller (which itself is just a rebranded Silicon Motion SM2246EN controller) with Micron 128Gbit 20nm MLC NAND. The random 4KB read goes up to 75K IOPS and the random 4KB write goes up to 75K IOPS as well. Its incompressible sequential read performance is excellent, while write performance is not as great overall. However, the drive has other advantages than pure speed.

Transcend bundles it with a custom firmware which enables encryption. While DevSleep is supported, slumber power modes, particularly HIPM and DIPM, are not. The drive comes with a 3.5″ desktop adapter for older machines, as well as a cloning utility via SSD Scope. It also features a StaticDataRefresh, which is similar to what other drives do to correct data errors due to cell degredation.

6. SanDisk Extreme II

Available Capacities: 120GB – 480GB
Interface: SATA 3 6Gbps
550MB/s read
510MB/s write

The Extreme II from Flash storage-giant SanDisk delivers excellent performance at a reasonable price point. It’s a predecessor to the Extreme Pro (see above), and likewise pretty old but still going strong as of 2016. Its sequential read speeds of 550 MB/s and write speeds of 510 MB/s are complemented by very good random read/write figures as well (95K/78K IOPS). SanDisk uses a controller from Marvell in this particlar line of SSDs – a chip with the fanciful designation 88SS9187 (also known as Monet) – with SanDisk’s own firmware and 19nm eX2 ABL MLC NAND (also from SanDisk), which makes for a particularly long-lasting combination according to several reports.

7. Samsung 850 EVO

Available Capacities: 120GB – 1TB
Interface: SATA 3 6Gbps
550 MB/s read
520 MB/s write

In spite of its low-end characteristics, i.e. Samsung’s use of TLC (Triple-Level-Cell) NAND, the 850 EVO performs extremely well. Not only is the sequential bandwidth excellent – the EVO also manages random read/write speeds of up to 100K/90K IOPS, according to the drive specs. While durabilty might be a concern with TLC-based drives, Samsung offers a 5-year warranty on the new EVO lineup, which is more than what you get with many high-end MLC SSDs.

It’s worth noting that the 850 EVO remains a technically superior alternative to its 2016 entry-level “successor”, the 750 EVO.

8. ADATA Premier Pro SP 920

Available Capacities: 128GB – 1TB
Interface: SATA 3 6Gbps
560 MB/s read (512 GB/1 TB)
500 MB/s write (512 GB/1 TB)

Adata also uses a Marvell controller in its SP 920 lineup, with the designation 88SS9189. This is combined with synchronous 20m MLC NAND from Micron, which results in excellent performance in the higher-capacity variants of the SP 920. The drive is available in capacities ranging from 128 GB all the way up to 1 TB, with the 512 GB and 1 TB models offering the best performance (and most likely durability).

It is important to note that there’s a large reduction in sequential write performance in the lower-capacity variants: Sequential writes drop to 360 MB/s in the 256 GB model and a mere 180 MB/s in the 128 GB model. 4K read/write IOPS also take a hit, particularly in the 128 GB version of the SP 920. Consequently, we award the spot in the ranking to the 512GB/1TB models only.

9. Corsair Neutron (GTX)

Available Capacities: 120GB – 480GB
Interface: SATA 3 6GBps
555MB/s read
333-510MB/s write

The Corsair Neutron GTX in many ways came as a surprise; not because Corsair produced another high-end SSD, but because of the unfamiliar controller from Link_A_Media Devices (LAMD)–a U.S.-based SoC manufacturer that was recently acquired by Hynix. The Neutron GTX’s sequential read speeds approach the limits of the SATA III interface at 555 MB/s. Sequential write speeds are 511 MB/s in the 240 GB and 480 GB capacities and 330 MB/s in the 120 GB unit. What is also impressive is that random read/write performance is equally high. In all, the Neutron GTX is a surprising but welcome addition to the high-end SSD market and shows that LAMD is a force to be reckoned with going forward.

10. Intel 730

Available Capacities: 240GB – 480GB
Interface: SATA 3 6GBps
550MB/s read
470MB/s write (480GB)

Intel was the number one choice in the SSD space for several years, with its semi-proprietery SandForce controllers and an endurance that few competitors could match (with a few exceptions). While the latter is still likely true (Intel offers a 5-year warranty on the 730 series) the latest drives from “Chipzilla” have not quite measured up to the competition in the high end. The 730 is nevertheless a very fast drive, particularly the 480 GB model. While the sequential read speeds are an impressive 550 MB/s in both capacities, sequential writes are significantly slower in the 240 GB model (270 MB/s).

M.2 Drives (2280/2260)

1. Samsung 960 Pro

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 512 GB, 1 TB, 2 TB
3500MB/s read
2100MB/s write

Samsung stays in the lead with this blazing fast m.2 PCIe drive. Like its predecessor, this m.2 drive supports 4 lanes of PCIe and uses NVMe for maximum bandwidth utilization and increased throughput. It uses Samsung’s own Polaris controller in combination with Samsung MLC V-NAND.

The 960 Pro supports TGC Opal and AES 256-bit data encryption. In the random read/write area, it delivers up to 440K IOPS for 4KB (QD32) random read and 330K IOPS for random writes (also 4KB/QD32). Reduce the queue depth to 1 and it still reaches an impressive 14K IOPS/50K IOPS read/write. These numbers, by the way, apply to the higher-capacity drives, while the 512 GB model is slightly slower.

Samsung offers a 5 year warranty with the 960 Pro as well as impressive endurance ratings of 1200 TB for the 2 TB model, 800 TB for the 1 TB drive and 400 TB for the 512 GB version.

2. Samsung 960 Evo

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 250 GB, 500 TB, 1 TB
3200MB/s read
1900MB/s write (1 TB)

The strongest competitor to the 960 Pro in the M.2 enthusiast segment is probably Samsung’s own 960 Evo – the more affordable variant of the 960. It is not quite as fast, although the difference is small enough not to be noticeable in everyday usage scenarios.

It might be slightly more concerning for some users that the 960 Evo uses cheaper TLC NAND circuitry. This cuts the durability rating in half, from 400 TB to 200 TB for the popular 500 GB capacity. The warranty is also reduced from 5 to 3 years. This won’t be a problem for the vast majority of the intended users, but worth keeping in mind.

In terms of raw performance, the 960 Evo is rated at up to 380K/360K IOPS random read/writes (compared to 440K/360K for the Pro) in the largest capacities (QD32).

In short: This is probably the M.2 drive to get at the time of writing if the price/performance ratio is an issue at all, and if you don’t plan to write copious amounts of data to it too often.

3. Samsung 950 Pro

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 256 to 512 GB
2500MB/s read (512GB)
1500MB/s write (512GB)

Samsung’s previous-gen champion is still a speed demon compared to much of the current competition; this m.2 PCIe drive also uses NVMe, a Samsung UBX controller and V-NAND.

The 950 Pro also supports AES 256-bit data encryption and reaches up to 300K IOPS for 4KB random reads and 110K IOPS for 4KB random write. As for reliability, Samsung offers a 5 year limited warranty.

The only reported problem that has been reported, as far as we can tell, seems to be that the drive could get too hot due to the increased clock speeds, and thus you may encounter thermal throttling if you’re not ventilating the chips well.

4. Kingston HyperX Predator

Interface: PCIe Gen2 x4 M.2
Available Capacities: 240 GB – 480 GB
1400MB/s read (480GB)
1000MB/s write (480GB)

While not as speedy as Samsung’s flagship, the Predator is still way faster than your standard SATA SSD. It’s flexible enough to use with every board thanks to the on-board OROM.

The HyperX Predator uses a Marvell 88SS9293 controller and Toshiba A19 MLC NAND. It can go up to 160K IOPS for 4KB random read and 119K IOPS for 4KB random write. Its mean time between failures is 1,000,000 hours. It also comes with a PCIe bracket since it’s aimed at desktop users who wish to upgrade. Finally, the warranty for this drive is 3 years.

According to some reports, it delivers lower battery life versus other Samsung drives, which makes it a less than ideal choice for laptops.
