Final Words

When Kingston released its 40GB version of Intel's X25-M last year, I liked it a lot. At $125, I still like the X25-V especially now that it has TRIM support. It's unfortunate for those who bought the Kingston drives last year, but it looks like there is a way to get TRIM working on your drives as well.

The X25-V is a great way to get an SSD into your system if you're not quite ready to splurge on a larger drive. With roughly 37GB of free space to install an OS and apps to, you can easily get your most frequently used programs on the drive. Pair it up with a cheap TB hard drive and you'll have ultra fast storage and a ton of capacity for under $250. Or if you're looking for something to make your travel notebook/netbook a lot snappier, the X25-V is perfect. The limited capacity does have performance implications as there's potentially fewer blocks to be used for cleaning, however TRIM helps alleviate that as an issue assuming you have a TRIM enabled OS.

Intel is quick to point out that pairing up two X25-Vs can give you more performance than a single 80GB X25-M for around the same price. While I'm still looking at RAID performance, the problem is that today there's no way to pass the TRIM command to drives in a RAID array. You gain better sequential performance and concurrent IOPS, but you have no way to actively curb performance degradation. In my opinion, that's not a worthy tradeoff. Intel did hint that its driver teams are looking at ways to pass TRIM down to RAID arrays however.

Kingston's answer to the X25-V is very interesting. You do give up another 10GB of space compared to the Intel drive for a formatted capacity of around 28GB, but in exchange you get better sequential write performance. Ultimately the tradeoff here is between sequential write speed and random read/write speed. The former is Kingston's advantage, while the latter is the X25-V's domain. PCMark Vantage favors Intel's X25-V, while our own storage bench preferred Kingston's 30GB Boot Drive. Given the X25-V's capacity and random read/write performance advantages, Intel gets the nod here over Kingston's 30GB drive if you're looking for a sub-$130 SSD. Note that if Kingston's pricing does manage to stay significantly lower than Intel's (thanks to Newegg's current pricing after MIR), Kingston might be a good alternative if you're looking to spend as little as possible and don't mind giving up some capacity for it.

While it's good to see competition at the low end of the SSD spectrum, I'm not expecting to see much more movement here until 25nm flash hits the market in Q4.

    Given it's in a similar size category...
    Shouldn't the 50GB OWC Mercury Extreme be included in this?
    Or is it only allowed to sit in X25-M territory?

    Is that the only other competitor for the Mercury Extreme?
    If true...
    In which scenario/s might one pick the Extreme over the X25-M?

    Thank-you!

    I actually bought one intel-v 40g and i got the shipment today. The sequential read is very good, 190mb/s with nvidia SATA controller driver and 170mb/s with win7 driver. However, the random read speed is only 22mb/s with both drivers, much lower than the test result 60mb/s. I still need to find out why.

    Hi Anand,

    I think it's misleading that you continue using the phrase "IMFT Nand". This gives the impression that all IMFT Nand is equivalent.

    IMFT does not sell Nand -- they are the just legal way that Micron and Intel can share the cost of manufacturing Nand together. Each parent company has the ability to define their own litho process or their own test strategies.

    This means that the Nand on the X-25 series is "Intel Nand", not IMFT or Micron Nand. Moreover, the Nand on the X-25 series receives much more extensive testing than what is sold to the removable memory market.

    Because of the growth size of the winsxs folder, I think 40GBs are to small for a boot drive.

    That might be the case for you, but not for everyone. I just upgraded my father-in-law's PC with one of the Intel 40GB SSD and a 250GB regular HD for data storage. Installation of Windows 7 Home Premium left just under 23GB of usable space. Besides IE, the only other thing he needed was Office 2003 (this took less than 350MB total). Still had 22GB of space left. It boots up very quick and opening programs in very fast (nearly instantaneous). A nice improvement over the previous incarnation with XP on a regular 7200rpm HD.

    28 or 37GB is definitely too small for me. If you're going to buy a SSD to speed things up, there must be enough space on it to actually install some stuff on it to speed up. If you can only speed up a few percent of your disk operations, it's pretty pointless.

    60GB would be the minimum for me, preferably 80+ GB. 30GB is barely enough for Win7 itself *or* a couple of games. I'm using 410GB on my "Applications" drive, the one that contains the OS and games and programs I use (almost no user data like movies or pictures).
