Intel DC S3500 Data Center SSD Review (480GB x 4) – Speed, Great Features and Rock Bottom Prices

MEASURING PERFORMANCE

As with all of our tests, the following tests were performed after a secure erase of the drive. The drive was also conditioned with a predefined workload until it reached steady state.  We also test across the entire span of the drive.

IntelS3500-SeqWrite

IntelS3500-SeqRead

For sequential operations, both the S3500 and SM843 are pretty evenly matched.  The S3500 holds a slight lead for writes, while the SM843 wins for reads.  Neither drive really separates itself from the other.  What was fun was putting four 480GB S3500s on an LSI HBA.  With a simple software RAID, we were able to get over 1200 and 1800MB/s for sequential read/write operations, respectively.

IntelS3500-RandWrite

IntelS3500-RandRead

Random 4KB reads and writes were the exact opposite of sequential operations.  The SM843 holds a slight lead for write operations while the S3500 pulls away in random 4KB reads.  On the flip side, it took four S3500s to match a single S3700 for random 4KB writes.  Those same 4 drives had no problem posting nearly 300K read IOPS.

Two things concern me with this SSD. The power protection caps look rather outdated compared to other enterprise SSDs. Secondly, the SSD label indicates a +12V line is required along with the usual +5V. My OCZ SSDs only required +5V . What’s the +12V being used for?

dravo1 – The S3500/S3700s can operate on both the 5 and 12V rail. 12V is useful in enterprise rack systems where it may be more readily available than 5V. All of our testing was performed in systems using only 5V, so don’t worry too much.

what about the SM843 with tantalum caps? or the SM843T with super caps and e-mlc?

We can’t say much about products that are not released, but if the 843 had power loss caps, it would be much more attractive to enterprise. If they add a high endurance option, that would put it in a difference price/performance class, so it’s hard to tell how it would stack up,

they are just sold through oem like samsung was before their consumer SSD. Used to be microcenter was the only place to get samsung hard drives. SM843T is the same as the 840 pro as far as they are concerned the factory OP is higher. the 840 Pro only worked after we moved to 30% OP with some megascu love to the LSI 9266

The write endurance seems to be pretty low though! 450000GB/800GB = 562 cycles. Others do something like 2-3000!

You need to the into account the WA aswell, especially becouse it uses no compression, it will always be more than 1.

Yes, with the JESD standard, the write amplification is 5-7X, from my experience. If you are looking at a workload where WA=~1, you are looking at slightly over 3000 PE cycles.

Does it work with macbook pro early 2011, core i7, 500gb? looking to upgrade to SSD.

Of course it will.
