Intel s3500 write amplification

In that workload, latency spiked only as high as 21ms. Please click the help button "? In these tests, we span workload intensity from 2 threads and 2 queue up to 16 threads and 16 queue.

Intel has also soldered power-fail capacitors on one edge of the board to protect in-flight data in the event of a power failure. For additional assistance, intel s3500 write amplification about this tool or to contact Intel, visit the Contact Us page.

Routinely, it beat out all of the competition soundly, except for the Seagate Pro. The sides of the SSD feature four screw holes that enable the drive to be mounted easily. Drilling into the average latency measured throughout the entire testing period, the Intel S shines in our NoSQL environment, with latency spikes staying between ms over the entire test.

For most buyers, the claimed latency figures are good starting points, but it really comes down to how the SSD performs in the workloads its destined to drive. The Seagate Pro came in towards the bottom in our MarkLogic NoSQL testing, with latency picking up significantly as the drive neared steady-state performance.

The sharp performance drop off is attributed to increased write amplification, as the drives are having to perform read-modify-writes for randomly written data going through garbage collection. This could be a major deal-breaker for enterprise customers.

Samsung 840 Pro or Intel S3500?

It handily beat out the Seagate Pro by a huge margin, keeping latency figures grouped closer together over the duration of the test.

Most capacities will be offered at launch, while others will show up over the next few months, and an early morning check on the day of release showed absolutely great great Amazon pricingwell below that of the DC S Series. It was an all-in-one drive that was just as comfortable with write operations as it was with reads.

The S also comes in a massive range of capacities that start as low as 80GB and range all the way up to GB.

In our application tests we did note exceptionally strong performance from the S, including class-leading performance in our MarkLogic NoSQL test. Bombarding the drives in this manner forces each SSD to run out of the free blocks that initially allow fast write times.

Taking a closer look at maximum latency shows us how consistent the drives are. Indeed, benchmark any of the above drives in a factory-fresh state and what you see are solid performance numbers throughout.

The test repeats itself over 24 intervals, requiring between hours total for the SSDs in this category. Compound this with great pricing and a controller that many have been just itching to see in a consumer SSD for some time and Intel just may have unexpectedly stumbled on a new crowd of buyers.

This test measures average TPS Transactions Per Secondaverage latency, as well as average 99th percentile latency over a range of 2 to 32 threads.

When left unchecked, drive-specific default WAF values are used in the calculations. Both draw a near-perfect line across the bottom of this graph, and this level of consistency is key in enterprise environments, where entire RAID arrays can suffer from performance anomalies in any one drive.

In one test, one SSD will edge ahead of the pack, then in the next, it will fall behind by a few percentage points.

Intel® SSD DC S3500 Series

The initial burst was near the middle of the group, though the S sustained its burst longer than several drives. They started with their world-dominating Pro, tweaked the firmware and pumped out the SM Specifically, WAF is calculated by taking the number of bytes actually written to an SSD divided by the number of bytes written as requested by the host.

Alternatively it could mean the percentage of time per day that the drive is being used at max performance. When it came to SysBench, the S was the top-performer in the light-enterprise group, though it lagged slightly behind the S When checked, each drive will have an additional input field where you can specify a custom value for the WAF.

From what we have observed on our test bench, SSDs in this class offer performance that is nearly identical. It had latency that crept up slightly compared to the S, with spikes measuring between ms.

The consumer drives from Samsung and Crucial have a wide scatter, occasionally taking up to 1,ms or up ms, respectively, to respond to a write transaction. Comparables for this review: Beyond that, the S features an in-house designed controller - the same controller that drove the S to deliver exceptional performance.

You can see the excellent read performance across the capacities. The burst and steady-state performance out-ranked the competition except at the very end of the test where the Seagate Pro caught up.Performance Consistency.

In our Intel SSD DC S review I introduced a new method of characterizing performance: looking at the latency of individual operations over time. The S promised a.

Intel® Solid-State Drive DC S Series Overview This document describes the specifications and capabilities of the Intel ® SSD DC S Series.

Intel® SSD DC S Series SATA storage for data centers provides fast, consistent read performance with strong data protection and low power levels. With peak and average sequential read/write speeds of / and / MB/s the GB Intel is about half as fast as the current group leaders.

Peak small file 4K read/write speeds clock in at 19/37 MB/s, again around half. The provenance of each drive makes some of the design decisions more understandable. But, before we get down to this mainstream enterprise showdown, lets have a deeper look at the S INTRODUCTION.

The Intel SSD DC S Data Center SSD is a read-oriented, enterprise SSD that comes in both 7mm ″ and 5mm ″ form factors.
