Random & Sequential IO Performance

Similar to our other Enterprise Iometer tests, queue depths are much higher in our Iometer benchmarks. To measure sequential performance I ran a 1 minute long 128KB sequential test over the entire span of the drive at a queue depth of 32. For random performance, I ran a 3 minute long 4KB random read test over the entire span of the drive at a queue depth of 32. Random write performance was measured at steady state (QD32), which varies depending on capacity and other factors. The results reported are in average MB/s over the entire test length.

Enterprise Iometer - 4KB Random Read

Random read performance is just excellent. The S3500 gives up nothing compared to the S3700 and ends up being one of the fastest enterprise drives we've tested.

Enterprise Iometer - 4KB Random Write

Random write performance takes a big hit compared to the S3700. At 47MB/s, the S3500 isn't bad but it's not class leading like the S3700.

Enterprise Iometer - 128KB Sequential Read

Sequential read speed is limited by 6Gbps SATA, and the S3500 has no issues hitting that limit given the number of NAND die inside the 480GB model. It's not until you get down to the 160GB version that performance will drop below 500MB/s.

Enterprise Iometer - 128KB Sequential Write

Sequential write performance is substantially better on the S3500, making this drive even better for large sequential caching applications.

    The difference is that the S3500 comes over provisioned and the others don't. While you and I have the knowledge and skill to do it ourselves, most people - even IT staff - would have zero clue or interest in how to do something like that.

    Give me a break, "most people" aren't interested in an S3500 period or even a prosumer drive, their primary focus would be capacity and cost (since at that level any modern SSD at all will be great). By definition, anyone interested in this or other such drives isn't "most people". "IT staff" or prosumers can perfectly well format/partition a drive, an easy GUI for it comes with every OS they'd use, it's hardly the kind of technical operation that'd make it a rare case. And since it only ever needs to be done once and then can be ignored forever, it can even be setup by someone else.

    Anand has considered it important enough to spend significant time on and test in all other recent reviews, and I think that speaks for itself. It's of direct relevance.

    does increasing overprovising on the intel drive change the performance much? this article compares s3500 to 600 pro but overprovising is much higher on the seagate drive (512gb of flash to get 400gb of storage). the intel drive is listed as 264gb of flash for 240gb and that translate to 512gb of flash for 480gb.

    also wondering how the pricing works out considering for the same amount of flash the seagate drives get 20% less storage space.

    As of right now it's been nearly 6 weeks since the last retailer and wholesaler received their shipments of S3700s. The word from most of them is that we're at least 6 more weeks away from the next expected deliveries. For those of us in the server world, it would be great if they could just produce and ship what they already make... and thus far throwing money at my monitor has done nothing.

    Regarding the testing methodology: on page 3, Mr. Shimpi said (as usual) the following: "To generate the data below I took a freshly secure erased SSD and filled it with sequential data". Ok, so how EXACTLY he did that? I mean, secure erasing the Intel SSD. I was in a couple of very frustrating positions, when I tried to secure erase Intel and Samsung SSD's, following the kind (read DUMB) suggestions of Samsung SSD Magician and Intel SSD Toolbox. On the Samsung drive I finnaly did it, I secure erased the drive. On Intel, no way. Intel SSD Toolbox kept saing that I must power down the drive, and then power on. But that din't work. I noticed a lot of angry users of Intel SSDs who could not secure erase their drive.
    So allow me to repeat the question: HOW MR. SHIMPI SECURE ERASED THE DRIVE? Thanks!

    Interesting, the comment about the high idle power usage making this drive not ideal for consumer use... Our channel partner was recommending this as a replacement for the 320 Series for our laptops.
  • mjz - Thursday, June 13, 2013 - link

    why would you even have to upgrade the SSDs in the laptops? I think your channel partner is just trying to make some money. The intel 320 ssd when used in a laptop is good for 98% of tasks

    Unrelated question but if you guys had a choice between having the Crucial M500 480GB or the Samsung 830 512GB for the same price which would pick overall?

    I continue to be a firm believer in Micron/Crucial and Intel's drives-quality and reliability and non-flakieness over (sometimes) better performance. ANY decent SSD for years now has provided crazy performance. As far as I'm concerned, that's now a moot point, save for drives that dip super low weirdly.

    What I care about is reliability and the testing these two companies do compared to other companies. I mean whoopdedo if one company makes an SSD that's 400 bajillion MB/s and another does 400 bajillian + 20 MB/s if the latter is going to corrupt my data after six months.

    I've currently got two Intel drives and Crucial in active use (one in my Playstation 3) and all of them have run great with zero issues. Thrilled that Intel's using their own controllers again and not the "we spent an entire year fixing Sandforce's gigantic bugs and it still has gigantic bugs" Sandforce stuff.

    Hmm, I guess actually I have a Samsung in my Macbook which has been okay too.

    Excellent job Anand! I just hope Intel can keep up with supplying these things; I tried to get my hands on an S3700 after they came out and they were all completely sold out everywhere.
