Kingston SSDNow V 30 GB (RAID 0)

SSD RAID: Do You Want A Cheap Array Or One Larger Drive?
By

The SSDNow V is a legacy product, which is currently being replaced by the V100. However, all the newer SSDNow products start at 64 GB capacity. This isn’t a bad thing, but it makes the product less accessible for such a RAID configuration, as users might specifically want to use four SSDs to maximize throughput. Obviously, four 64 GB SSDs are clearly more expensive than four 30 GB models. In the end, somewhere around $150 for two 30 GB SSDs isn’t that bad.

Be that as it may, we got ourselves two of Kingston’s SSDNow V 30 GB twin kits. This means that each kit consists of two 30 GB drives, providing us with a total of four test drives. All SSDNow products come with at least a three-year warranty, and the kits include a SATA cable and a Molex-to-SATA power cable. Finally, we also found mounting brackets inside the Kingston box. These are required to install the 2.5” SSDs into 3.5” drive bays for almost every desktop-class PC case.

Inside Kingston’s SSDNow V 30 GB

The SSDNow V 30 GB is based on Toshiba’s T6UG1XBG controller and Micron NAND flash memory chips. The solution typically provides limited I/O performance and nice throughput, but in such a minimum configuration with fewer flash memory channels and only 30 GB, we’ll see that the resulting performance does have its limits.

Kingston’s PCB is pretty small; it does not even use half of the footprint available on the 2.5” form factor. We doubt that this format could be recycled for the 1.8” form factor, but it would be technically possible to create a shorter 2.5” SSD based on this PCB. It’s also interesting to see that the entire PCB is labeled with ‘Toshiba.'

We used two and four of these SSDs for this article, each setup running in RAID 0 to maximize performance.

    How about a simple comparison of 2 of the smaller sandforce drives 2x60GB in raid vs one 120GB drive? There should be not much difference in price, which i assume people will pay (me included) if there is enough performance improvement. I see no point in comparing raid arrays of such low performing and phased out drives.

    Why would you pick such inferior drive in the RAID array for this test? $150 for two 30GB drives isn't saving you any money. Why not get two of the Zalman N Series SSD0064N1 for $129 at a website I could name? You'd get MORE storage for LESS money. You'd also have a far superior controller in a two drive array. THAT is the best setup.

    Nice read. I didn't even consider this when looking at SSD's but I'm glad you shined some light on this. I guess for gaming it's best to go with one bigger SSD. Thanks for the article. :)

    Please tell me of this website! I can only find one of those SSD's for that price...

    On another note, after reading this article I think I made up my mind in a future build to have SSDs in raid for my OS and games paired with three 320gb HDDs I already own for more storage and backup. I am particularly interested in the read speeds more than anything.

    This is coming Edisonmk, just an FYI. In the same piece I'll also be comparing the dual-controller RevoDrive and quad-controller RevoDrive X2 (along with Intel's X25-M and OCZ's IBIS).

    I agree... Apples to Oranges comparison isn't the best way to go forward with this.

    Pick a manufacturer, and a specific line of drives by that manufacturer, pick 4 low cap drives, 2 med cap drives, 1 high cap drive. Compare them! The final drive in these tests should be approx the same size.

    Test on all metrics per usual. Compare/Contrast results and provide Price/Performance analysis.

    I'd like to see the benchmarks on two 128GB Crucial RealSSD C300 in RAID 1.

    r_padI'd like to see the benchmarks on two 128GB Crucial RealSSD C300 in RAID 1.

    in RAID1, i imagine the performance would be almost as good as a single 128GB Crucial RealSSD C300

    I think raiding these would be nice and worth doing honestly most people looking for a SSD want them for the access time and sequential reads when it comes down to it and even the writes aren't horrendous for the S100 series I imagine in 2+ raid array setup they'd be very reasonable.

    Interresting test, but the comparisons are like comparing 4 paintball guns mounted on a stick with a common trigger to an AK-47.
    Redo the test with 1, 2, 3, and 4 SSD at 32 or 64GB compared against an SSD at 256GB using the same controller, and ffs, use a controller that is modern.
    I suggest SandForce or C300.
    I'm currently on an SSD RAID of 4x C300 64GB running on AMD SB850. I have 1150MB/s sequential read, 280MB/s sequential write, 32MB/s 4KB random read @ QD 1 (8k IOPS), 80MB/s 4KB random write at QD 1 (20k IOPS), 400MB/s 4KB random read at QD 32 (100k IOPS, maxed out at 2 drives), and 270MB/s 4KB random write at QD 32.

    4x SSD = 10 to 15 watt... When most video catds use 30 watts at idle, and capable of hiting over 200 watts, it kinda seems silly to think about a measly 10 to 15 watts of power for RAID storage.

    Then again... I do have 2 rooms in the house with LED lighting...

    I have one of these 30gb SSD from this brand and my results were a little better in other test than what you have gotten but I didn't get it as a os drive but as a paging drive. Modern hard drives are far to slow when it comes to random 4k and it shows up in games that have a very large memory foot print like GTA IV.

    What about TRIM???

    My understanding is that although it is possible to connect a single SSD to a RAID controller and use TRIM, it is *not* possible to use TRIM on an array.

    Has this changed??????

    If not, then your RAID array's performance will inevitably decrease over time. And I would opine that end users would be better off buying a newer/faster/larger single drive.

    Interesting article, the take away for me is this.....maybe I would enjoy getting a 2nd Intel X25-M G2 80GB drive and do a RAID 0 hehe

    I don't think soft raid is good if you want speed.

    Clearly explained in the last statement of the article: We'll also dive into the implications of using an SSD-based RAID array on TRIM support in an upcoming story, so stay tuned!

    I was wondering this all along. They should have used better small drives like OCZ's 40 GB Vertex2, which use the SF-1222 controller, instead of the Kingston units. The performance of the smaller SandForce-based drives is supposedly similar to their larger variants, so that would give you the best idea of RAID vs. one big drive.

    Actually, performance degrades only to a certain point, depending on your usage patterns, and affect only write performance. With the performance level of RAIDs of decent new SSDs, you wouldn't notice it, but could meassure it after heavy usage with a benchmark.

    And if you can do so, not having write-heavy things on your SSDs helps a lot too. If you're on a desktop, you probably have a mechanical HDD for data. Putting some of the write-heavy folders on the mechanical HDD will result in very few writes to the SSD. I did this with my two-drive SSD RAID and after two months of use, the SSDs still report less than 64 GB of writes as compared to half a terabyte of reads on each SSD.
