    Really fast, pretty small, 1 Jun 2011

    I picked up one of these a few days ago to complement a newer Sandy Bridge setup. For no reason I could ever figure out, my boot times were terrible with the motherboard (an Asus P8P67 Pro) using a conventional HD – on the order of 3 minutes from cold until the PC was responsive. Connected to a SATA-3 controller, this SSD reduced my boot time to around 35 seconds, and, once the desktop appears, the PC is fully responsive to whatever you want to do. It sounds obvious, but the main thing that differentiates SSDs from conventional HDs is this “snappiness” factor – seek times are completely flat, thus, the only delay is actually transferring data off the drive to RAM for CPU operations (and this drive is capable of >400 megabyte per second bursts). The drive is also completely silent, and it’s slightly weird not to hear the usual HD ticking & clicking. You may also need a 3.5″ drive bay adapter; physically, the drive is about 50% bigger than a credit card and very light – alternatively, I have seen these drives held in place by double-sided tape – with no moving parts, you can pretty much put them anywhere the data and power cables will stretch. Also, a side effect of the “solid state” part of the drive is that it is largely unaffected by any movements or accidental drops – anything that doesn’t destroy the casing will leave the drive completely unaffected – the interior is largely the same as a USB flash drive, but with larger capacity chips and a small controller.

    I initially had some trouble with the drive (some stuttering and pausing) after installing Windows7 then Intel’s RST drivers (the drive is connected to an Intel ICH9 port), and decided that a re-format would be my best option to completely get rid of the Intel drivers. When installing Windows only takes 12 minutes – and at that, you’re largely limited to your DVD drive’s transfer rate more than anything else, it’s no longer a chore, and using Win7′s built-in ACHI drivers fixed the problem completely.

    There’s also a little more to installing one of these compared with a standard HD. You should connect it to a SATA-3 drive port to get best performance (although it will remain very fast if you’re using a SATA-2 port on older motherboards). You also need to run the Windows Experience Index in Windows7 (and in fact, use Windows7 too, since it contains drive control commands optimised for SSDs not found in older versions of Windows). When Windows has run the Windows Experience Index, it will fully recognise the drive as an SSD and automatically disable some scheduled processes like defragmentation etc. Lastly you can check your speeds are what they should be with e.g. AS SSD Benchmark – sequential reads should be over 300 or 400 megabytes per second depending on the controller you’re using, and if so, you’re good to go.

    Obviously, the downsides to this drive are the high cost and relatively small capacity; at 120GB after formatting, a default installation of Windows7 itself will immediately eat another 17GB or so, so you’re basically looking at 100GB all told once you’re set up. While smaller applications like web-browsers etc. load more or less instantly now, more extensive applications show less benefit – e.g. a modern multi-gigabyte game will only show speed differences of a couple of seconds. In all, it’s a mixed bag, but, I could see myself abandoning conventional HDs in the future as prices come down over time. If you need very large quantities of storage space, you won’t want to use these, but 100GB is minimally useful for a working system plus a few apps. And of course, you can continue to use any existing HDs you have for secondary storage.

    EDIT : Been running this drive for slightly over a year now with no real ill effects, although I am finding the 128gb quite cramped now with the addition of a Dropbox account (weirdly, even though the Dropbox folder is on another, larger drive). A minor speed-bump was the firmware update Crucial sent out late last year where unless installed, the drive would reboot itself after (x) thousand hours of use. As a bonus, however, once you have the update installed, you get an extra 100mb/sec speed boost, so it’s not all bad – although the bug would effectively prevent you from using your PC for more than an hour at a time.

    Since I bought this, prices have roughly halved, and I’m strongly considering getting another one of these in the 256GB flavour to complement the existing one.

    Great Performance, 31 Oct 2011

    I got this to coincide with my intention to do a fresh install of Windows 7. I had originally upgraded to Windows 7 from Vista. This worked OK but then I upgraded again from Windows 7 32 bit to 64 bit and had all sorts of problems with the PC not seeing all my RAM and it kept crashing. I therefore decided I would buy an SSD and load Windows 7 64 bit onto it as a clean, new installation. Physically installing the SSD was simple with an adaptor tray to make use of a spare 3.5″ bay. I disconnected all my SATA HDDs so only the SSD was connected. I connected it to a SATA 3 socket, ensuring I used the correct cable that had been supplied with my motherboard (no cables supplied with the SSD). I put the Windows 7 64 bit disc in a DVD drive, ensured the boot sequence was set to the DVD drive and the Hard drive type was changed from IDE in BIOS, and booted up. The installation began OK but when it asked to choose a drive to install the operating system, there were none present. Clearly the SSD wasn’t formatted and there was nothing in the included instructions to suggest this. I therefore connected the HDD with Win 7 still on it, changed the boot sequence and switched on again. The intention being to use Win 7 to format the SDD, however when Win7 booted up it couldn’t see the SSD either! I tried all sorts but in the end I temporarily connected the SSD to a SATA 2 socket. Win 7 then saw it so I formatted it, reconnected it to the SATA 3 socket and checked Win 7 could still see it and it could. I then reset the boot sequence, disconnected my old HDD again and booted to the Win 7 disc. This time it saw the SSD and the installation was completed. I’ve now reconnected all my HDDs and restricted what I’ve loaded to the SSD to just those applications where I need speed. The PC is running reliably without crashing and it’s seeing all 8Mb of RAM. The main observation is the speed of boot up. Overall I’m very pleased with the performance and my only criticism is the lack of information included with the SSD. Crucial seem to assume these drives will only be installed by experts!

    Crucial M4 SSD Turbo-charged my PC, 29 Dec 2011

    I use my PC mainly for gaming (racing/simulator), photo processing, video creation, working on documents, entertainment (music and videos) and internet browsing.
    Before the Crucial M4, my PC configuration (based on a P55 chipset) looked something like this: Windows 7 64-bit, Processor: i5-760 (@ 2.8 Ghz), 8 GB RAM, 2xGTX 460 (in SLI), 1 TB HDD.

    My choice for the HDD (spinning at 5400 rpm) wasn’t the wisest and I could see how much it affected my system’s overall performance. Adding a SSD-HDD was really the only way I could maximise the potential of my system.

    I’ve been watching the evolution of the SSDs from the the past couple of years. Apart from the prices, (earlier) firmware issues kept me from investing in a SSD-HDD.
    However, as the performance of the SSDs had started to become more stable (compared to earlier), I thought it was the right moment to start looking for something to upgrade my system with.

    Since the SSD will be used as a system drive (OS+programs and the current game that I’m playing), a 120/128 GB SSD-HDD was my target.
    My criteria for selection were:
    1. Performance on SATA III (6 Gbps) – although my system supports only SATA II, I wanted something that was ‘future-proof’
    2. Performance on SATA II (3 Gbps) – this was a critical point for selection
    3. Reliability – many ‘performance oriented’ SSDs have the reliability of a leaking boat. I wanted something that had a proven track-record for reliability
    4. Performance per $
    5. Cost per GB

    It took me almost two weeks to gather enough information about all the SSDs in the market and check if they met my criteria.
    Many SSDs failed to meet criterion #2, which shortened my list to about 5 names.

    The controller on the SSDs impacts the performance and also the reliability of a SSD. Sandforce controller based SSDs show better performance, but reliability differs from SSD manufacturer to manufacturer.

    I was left with 2 names in the end: Mushkin Chronos Deluxe and Crucial M4.

    The ultimate winner for me was the Crucial M4 for the following reasons:
    1. Performance on SATAIII may not be the best, but with the 0009 firmware update, performance levels are right amongst the top Sandforce controller based SSDs.
    2. Crucial M4 SSD drives have shown the least percentage performance drop when operating on SATAII. The Sandforce controller based drives, except the Mushkin Chronos Deluxe, are hit badly.
    3. In terms of reliability, only Intel, Mushkin and Crucial have shown sustained stable results.
    4. Crucial M4 ranks amongst the top SSDs for performance per $. It is only bettered by its older sibling the C300.
    5. Crucial’s SSDs have by far the best (or almost the best) cost per GB over the entire range of SSDs offered by any manufacturer.
    6. Availability of Crucial M4 drives is better than Mushkin Chronos Deluxe.

    Migrating my system drive (C:) from my old HDD to the Crucial M4 with a $19.95 software made a big mess. After migration, the SSD drive was not configured for optimum performance and after 3 re-boots, my geniune Windows 7 got invalidated. This forced me to take the much preferred route of a fresh install.
    Doing a fresh install (or reinstall) in the past was always a daunting task taking me sometimes up to 2 days to set up my PC right – with all required programs, settings etc. This incredible drive shrunk that time to 4 hours!!!
    The performance after the fresh install also improved significantly. The AS-SSD score went from 365 (post-migration) to 515 (fresh-install) – not bad for a SATAII.

    To summarise, metaphorically, the addition of the Crucial M4 128 GB to my system is like the BMW M5. It is one of the best ‘track-day’ weapons, and it also seats 5 persons!
    Kudos to Crucial for a great product!
